The apparent rarity of sexual propagation~ which might possibly lead to the formation of cocoons so small as to be readily carried about by the wind, may have something to do with this encystment. The cysts are small enough to travel very easily, and the wide distribu- tion of the species may have been thus brought about. III.~Notes on Lon.qleorn Coleoptera of the Group Cerambycinab with Descriptions of new Genera and Species. By CItARLES J. GAI-IXN, M.A.,'Assistant in the Zoological Department, British Museum. [Concluded from vol. vii. p. 34.~ I~r my two papers on this group of Longieornia which have already appeared I have dealt with African~ Indo-Malayan, and Australian species. The present contribution is confined to South-American species of the group. t[amraaticherus macrus~ Bates. Mr. Bates's clear description of this species leaves no room for doubt that it is identical with tile Itammaticl~erus bellator of Dejean's collection. It isvery doubtful, however, whether Serville's description could possibly have been drawn up fi'om the same species ; if it is to be accepted as accurate we must regard the tt. bellator of Serville as a species allied to but quite distinct from H. macrus, Bates (=//. bellator, Dej.). It may be remarked that in the latter species the anterior cotyloid cavities are distinctly open behind, while in all the other species known to me they are completely or almost completely closed in behind.

Prothora,~ crossed above by about nine tolerably regular transverse ridges~ exclusive of the raised anterior and posterior margins ; fur- nished at the middle of each side with a rather feeble tubercle. Elytra each truncate and bispinose at the apex. Prosternal process feebly tubereled. This species is to be distinguished by the structure of its antennse t¥om every known species of the genus. In eolour and general appearance it most nearly resembles a variety of IL pl(catus~ Oliv, which is characterized by the absence of the dark bands from the margins of the elytra.

Tile colour of the eiytra is ahno.st the sam% but the pubescence has a slight greenish or yellowi.sh tinge. Tile ridges of tile prothorax are more numerous and a little less regularly transverse. The fifth joint or' the male antenna is without a distinct spine. Tile head is more distinctly carinate between the upper lobes of the eyes. Hammatlcherus yt~ncttdatas, sp. n.

P~othorax crossed above by about eleven transvers~ ridges in addition to the raised anterior and posterior borders the sides each with two tubercles--one at the middle, the other, distinct though obtuse, a little behind the anterior margin. Elytra elongate, feebly and somewhat sparsely punetulate, reddish brown, with a faint greyish pubescence, each truncate and bispinose at the apex. This species may be distinguished from H. barns, Linn., and its allies by the punctuation of its elytra, by the second distinct tubercle on each side of the prothorax, and by having the fifth joint of its antennae equal in length to the third. In H. batus and H. mexicanus the fifth joint of the antenna~ is a little shorter than the third ; the prothorax has a slight thickening of the ridges, or callosity~ on each side near the anterior margin ; the elytra are ahnost destitute of punctua- Downloaded by [Moskow State Univ Bibliote] at 13:36 28 January 2014 tion beyond the excessively minute pits from which tile hairs of the pubescence spring. ]n H. punctulatus the stridulating surface of the meso- notum is less finely striated than in allied species ; but [ do not yet know whether this character may be relied on as a specific distinction.

This species somewhat closely resembles tt.plicatus, Oily., bnt the prothorax is more pubescent and its plication some- what less regular towards the middle, and the elytra are without dark margins.
