(Pablished by permission of the Trustees of the British Museum.) A SMALL collection of Diptera Nematocera recently made by ]Hr. J. C. F. Fryer in Ceylon contains a number of interesting forms which it seems desirable to place on record: several appear to be new to science, while others, previously known from other regions, have not till now been recor~ted from Ceylon. The types of the new species have been generously presented to the National Collection by Mr. Fryer. In addition to the species referred to in more detail below, the Downloaded by [ECU Libraries] at 10:07 30 March 2016 collection contains the follo~ving :wSciara rufithorax, Wulp ; Leiomyia areuata (Brun.); Allaetoneura eineta, Meij.; Pleeia fulvleollis, F.; Phlebotomus maeulatus, Ann. ; /~s~- ehoda albopicta, Brun. ; Ochlerotatus palliclostriatus (Theo.); W~jeomyia greenii, Theo.; PsellioThora taprobanes (Walk.) ; Tipula ochripes, Brun. ; _Pachyrhina Tleurinotata, Brun.; _Paehgrhiua P javensls, Dol. ; Libnotes pceeiloptera, O.-S. ; Teueholabisfenestrata, O.-S. ; Teucholabis (6~ymnastes) e~tanea, Edw. ; Conosia irrorala~ Wied. ; ~riocera cr~/stalloptera, O.-S. ; ~7. tuberculifera, Edw.; E. etenophoroides, Edw.; E. albonotata, Lw. 200 Mr. F.

Head yellowish, more brownish on the vertex; antennm with the first three joints yellowish, the remainder dark brown; palpi brownish. Thorax yellowish brown; a dark brown vertical stripe on the pleurm, extending on to the sides of the mesonotum, situated between the first two pairs of legs. Abdomen brownish yellow, the middle segments indistinctly darker at the base. Legs yellowish brown, the tarsi somewhat darker. Wings bare; apical third occupied by a large dark brown patch, the anterior edge of which is rather irregular and has a large angular projection on Cul ; another brown patch towards t-he costa near the middle of the wing, filling the greater portion of the eell R1 ; a small one near costa, more towards the base, including origin of Rs, and a brown spot in t!m cell Cul a little way from the base ; Se reaching costa opposite origin of Rs. H~lteres yellowish, knobs dark. Peradeniya, ix. 1911 ; 4 d'- The strongly darkened apical third of the wing plainly marks this species off from the seven described by Brunetfi from the Orient.

There is no doubt as to the above syrronymy, since tim genitalia of the Ceylon and Seychelles specimens appea. Diptera IYematoeera from Ceylon. 201 identical and the coloration is practically the same, the only difference being that the Seychelles specimens have a more or less distinct dark fascia near the apex of the wing, which in the Ceylon specimens is so faint as to be practically absent. The lateral oeelli are absolutely contiguous with "tim eye- margins and the subcosta is very faint in its apical portion, not distinctly reaching the costa. These two peculiarities no doubt led Brunetti to place the species in Rhymosia, but the general appearance and (apart from the evanescent subcosta) tire venation are those of a typical Leiomyia. Precisely the same peculiarities are exhibited by Leia seyehellensis, End., and by some undeseribed African species which I have examined. Brunetti's Rhyrnosia annulieornls and R. flume- falls are doubtless also species of Leiomyia. Le~omyia, Rend. (emended form of Lejomya, RondO, is the name which should be used for Glaphyroptera, Winn. Leia, Mg., is wrongly applied to it. Since Winnertz was the first person to divide Meigen's Leia~ by the rules of the Zoological Congress hm mterprctatmn must be followed. Gurtrs desl¢- nated a type of ieia whictt Winnertz did not accept, and Rondani renamed the genus, thinking the original name was preoccupied ; but these facts are altogether irrelevant.

This species is very much iike the following ; it differs in the dull brownish-black (not shining black) thorax, which is only very slightly produced forwards and does not end in a sharp point; also in the yellow (instead of black) femora and tibim. By the last-named character it also differs from M. albitarsis, Mg. 6. Macropeza #ibbosa, Wied. Analecta Enf. p. I0 (1824:). Calylotopo#on albitards, Kieff. Mere. Ind. hIus. ii. p. 209 (1910).

Wiedemaun's brief description of M. glbbosa notes all tile more salient features of Kieffer's G. albitarsis, and tile two m~mes may be safely considered to apply to the same species. The genera Macropeza and Cal!/lololooyon are so similar that the propriety of their separation seems open to question. Tipulid~. 7. Tipula gracilllma, Brun. Fauna Brit. Ind. p. 302 (1912).
