Zusammenfassung Vorliegende Arbeit ist eine Fortsetzung und gleichzeitig ein vorläufiger Abschluß der obengenannten Artikelserie, von welchen der letzte Beitrag in den Annalen des Natur- historischen Museums 78, 1974: 457 — 472 erschienen ist. Es handelt sich um die Be- schreibung einer neuen Gattung, Xylocryptus, 50 neuen Arten und 3 bisher unbekannten Geschlechtern von Scolytiden, sowie 34 neuer Platypodiden, zum größten Teil aus einer breit angelegten Versuchsserie mit Leimtafeln in der Umgebung von Bulolo stammend. Mit diesem Zuwachs erhöht sich nun die Zahl der festgestellten Scolytiden aus Neu Guinea und den umliegenden Inseln auf 46 Gattungen mit 374 Arten und 9 Gattungen mit 218 Arten an Platypodiden, von welchen nur ein sehr geringer Teil auch aus den westlich an- grenzenden Sundainseln bekannt ist. Die weitaus größte Zahl der Arten sind demnach endemisch für Neu Guinea, wohl ein Zeichen dafür, daß das in Frage stehende Gebiet als ein randständiges Evolutionszentrum zu betrachten ist. Die Veröffentlichung dieser Arbeit in den Annalen des Naturhistorischen Museums wurde mit Herrn Wirkl. Hofrat Dr. Rudolf SCHÖNMANN besprochen und scheint umsomehr berechtigt, als die dabei festgestellten Holotypen in der Sammlung SCHEDL = Natur- historisches Museum eingeordnet sind.

Abstracts This paper, the preliminary last of a series, deals with the description of a new genus, Xylocryptus, 50 new species and three new sexes {<$) of Scolytidae, 34 new species and four new sexes ( $) of Platypodidae gained from large scale sticky trap experiments carried out near Bulolo, Morobe District, from 1972 to 1974, organized by the Department of Forests, supervised by Dr. Barry GRAY and assisted by F. R. WYLIE and P. SHANAHAN. Including this material in New Guinea and the surrounding islands so far have been found 374 species of Scolytidae belonging to 46 genera and nine genera of Platypodidae with 218 species. The fauna consists of rather few species also found on the western Sunda Islands while by far the majority is endemic to New Guinea and the islands east- ward to New Caledonia thus indicating that this region represents a distinct evolutionary centre still in progress not expected a few years ago. This situation may still become more

Scolytidae P achy cotes araucariae n. sp. Male. — Piceous, 2.7—3.0 mm long, 2.3 times as long as wide. From Pachycotes australis SCHEDL it might be distinguished by the smaller size, the more elongate shape, and the extreme short pubescence on the elytral declivity. Front convex and minutely punctulate below, with a shallow transverse depression showing a dense rather coarse punctuation above, without remark- able pubescence. Pronotum wider than long (31: 28), trapezoid in outline, widest at the base, postero-lateral angles rectangular and closely attached to the elytra, sides slightly narrowed in nearly straight lines in the basal half, thence with a distinct subapical constriction, apex very broadly rounded; disc slightly ascending from apex to base, with a very shallow depression connecting the subapical constrictions on the sides, surface minutely punctulate, therefore silky shining, also very densely covered with large moderately deep punctures, pubescence inconspicuous. Scutellum submerged. Elytra but little wider and 1.5 times as long as the pronotum, base finely crenulate, sides parallel on the basal three fifths, apex very broadly rounded, declivity short, strongly convex; disc striate-punctate, the striae rather deeply impressed, the striai punctures indistinct, interstices wide, convex, minutely punctulate, therefore nearly opaque, each one with a median row of remotely placed punctures near the base, replaced by small granules behind, all bearing (as far as not abraded) short semierect hairs, the granules but little larger on the declivity, moreover with an extremely short and densely placed ground vestiture. What is believed to be the female has the front more uniformely convex. Holotype (male) in Collection SCHEDL, allotype in the Collection of the Department of Forests in Bulolo.

Cladoctonus contractus n. sp. Ferrugineous, 1.8 mm long, 2.4 times as long as wide. Compared with Cladoctonus elongatus SCHEDL the new species is smaller, a little stouter, the elytral disc with its striate-punctate sculpture more clearly defined and con- tinued on the declivity. Front convex, shining, very densely moderate finely punctured, nearly glabrous. Pronotum about as wide as long, postero-lateral angles rectangular, slightly rounded, sides straight and somewhat convergent on basal half, ©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at New Scolytidae and Platypodidae from Papua and New Guinea IV. 341

apex rather narrowly rounded, with a very distinct subapical constriction; disc uniformely convex from apex to the base, a summit rather difficult to recognize, shining, covered with medium sized punctures being crowded on anterior third, more remotely placed around the supposed summit, a few scattered erect hairs anteriorly and on the sides. Scutellum submerged. Elytra little wider (37 : 34) and 1.7 times as long as the pronotum, base crenate, sides parallel on basal half, apex broadly rounded, declivity comprising the distal half of the elytra and rather strongly convex; disc somewhat shining, striate-punctate, the striae wide and deep, the striai punctures large, partly rectangular and closely placed, interstices narrow, each one with a fairly regular row of more remotely placed smaller punctures, towards the base these punctures replaced by blunt granules, on the declivity by larger pointed tubercles and short erect hairs.

Cosmoderes papuanus n. sp. Testaceous (immature), 1.5 mm long, 2.8 times as long as wide. General appearance as in Stephanoderes birmanus EICHH., but smaller, more slender and with the antennae corresponding the description of Cosmoderes EICHHOFF. Years ago I have seen the Type of Cosmoderes monilicollis from the Museum Hamburg. Unfortunately both antennae were missing, therefore identification can only be based on the original description by EICHHOFF. Front convex, subopaque, minutely punctulate, also somewhat coarsely punctured, eyes large, stout oval, without distinct emargination on inner side. Antennal club large, subcircular, narrowly emarginate at the insertion of the funicle consisting of one rather longe cylindrical joint and the large pedicellus, exterior face of the flat club with scattered long hairs. Pronotum little longer than wide (28 : 26), postero-lateral angles rectan- gular and slightly rounded, sides subparallel on basal fourth, thence gradually incurved, apex moderate broadly rounded, apical margin with six asperities, decreasing in size laterally, the two median ones large and fused at the base, blunt at the tip; summit rather high, situated in the center, anterior area steeply convex, with numerous large remotely placed blunt asperities, basal area very densely covered with medium sized punctures bearing minute inclined hairs. Scutellum triangular, finely punctured. Elytra little wider (28 : 26) and 1.7 times as long as the pronotum, sides parallel on little more than the basal half, apex moderate broadly rounded, declivity restricted to the distal two fifths of the elytra, obliquely convex; ©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at 342 K. E. SCHEDL disc shining, with not quite regular rows of rather small partly indistinct punctures, interstices wide, each one with a row of fine punctures bearing slender semierect hairs, towards and on the declivity these hairs replaced by spatulate scales and the groundsculpture becoming minutely punctulate.

Cosmoderes elegans n. sp. Castaneous, 1.44—1.66 mm long, 2.6 times as long as wide. Easily dis- tinguished from Cosmoderes papuanus SCHEDL by the finely asperate anterior part of the pronotum, the numerous small and closely placed asperities on the apical margin of it and the regularly striate-punctate elytra. Front convex, but little shining, finely granulate-punctate, with a small tubercle in the middle shortly above the epistomal margin. Pronotum about as long as wide, appearing more slender on account of the oval outline, postero-lateral angles little more than rectangular, sides slightly divergent on basal fifth, thence gradually incurved, apex moderate broadly rounded, apical margin with numerous small triangular asperities ; summit little behind centre, anterior area obliquely convex, densely covered by small asperities but not arranged in concentric semicircles, basal area nearly opaque, very densely granulate-punctate, the interspaces minutely punctulate, entire surface with short erect hairs. Scutellum moderate in size, subopaque, finely punctulate. Elytra as wide and 1.7 times as long as the pronotum, sides parallel on basal half, slightly incurved behind, apex rather broadly rounded, declivity commencing in the middle, rather obliquely convex; disc striate-punctate, the striae very shallow, the striai punctures rather coarse, the interstices narrow, minutely punctulate and each one with a median row of punctures bearing short semierect setae; on the declivity the striae more impressed, the setae of the interstices somewhat spatulate at their tips.

Margadillius concentralis n. sp. Dark reddish brown, 1.1 — 1.2 mm long, 2.4 times as long as wide. A new species easily recognized by the asperities of the anterior part of the pronotum arranged in concentric semicircles and fused at their base. Front convex, minutely punctulate, also with some scattered fine punctures. Pronotum about as wide as long, postero-lateral angles rectangular, sides subparallel on the basal half, semicircularly rounded at the apex, without distinct subapical constriction; summit situated in the centre, anterior area convex, minutely punctured and with three to four rows of asperities fused at their base and therefore arranged in concentric semicircles, basal area somewhat transversely impressed and very densely granulate-punctate, pubescence very short, scattered, inconspicous.

Xyleborus granulosus n. sp. Ferrugineous, 3,2 mm long, 2.3 times as long as wide. A very peculiar species with a rectangular pronotum, a shape so far observed in males only, but as these two specimens have been taken on sticky traps, they must have been on the wings, and after our large experience males within the genus Xyleborus can not fly at all.
