middle of end of second sul)marginal cell ; light mark (upper 

 margin of rosette) immediately beyond stigma small and 

 narrow ; posterior cells crossed diagonally by several series 

 of disconnected or semi-disconnected moniliform marks, and 

 all except fourth with a light mark in distal angle on wing- 

 margin ; discal cell with a minute light mark in proximal 

 angle, a transverse mark before middle, and a more or less 

 incomplete loop in distal half ; markings in basal and axil- 

 lary cells of normal type, apex of anal cell not light-coloured.

Hcematopota torquens is closely allied to H. cordigera, Bigot 

 (Ann. Soc. Ent. Fr. Ix. 1891, p. 3G9 *—nec Bigot, Mem. 

 Soc. Zool. Fr. V. 1892, p. 62Gj, the type of which from 

 Assini, Ivory Coast, I have been enabled to examine through 

 the courtesy of Mr. G. H. Verrall, in wdiose possession it 

 now is. These two species present a strong similarity to 

 each other in certain details, such as the shape of the frontal 

 callus and antennas, but H. torquens is distinguished, inter 

 alia, by the disk of the scutellum being brown, like the 

 remainder of the dorsum of the thorax, instead of smoke- 

 grey, by the deeper yellow colour of the hair clothing the 

 dursum of the thorax, the paler femora, the first joint of the 

 hind tarsi being cream-buff except the distal third, instead 



* Syn. H. guineensis, Bijrot, Bull. Soc. Zool. Fr. xvi. 1891, p. 76. 

 Although the name guineonds was published before cordiyera, Bigot 

 (Auu. boc. Eiit. Fr. loc. cit.), the description (only two Hues) is too short 

 to be recognizable. In the original label on the type of H. cordiycra 

 (Ann. Soc. Ent. Fr. loc. cit.) the word cordiycra has been struik out and 

 (fuineensis inserted below in Bigot's handwriting. It is evident that 

 Bigot, after reading (February 11, 18'.)1) his piper on the Diptera 

 collected by M. Ch. AUuaud in Assini, in whith the original //. cordi- 

 yeia was described (Ann. Soc. Ent. Fr. loc. cit.), thought that the name 

 C'</v/!(/era would be more appropriate to the species from India to whicli 

 it was applied by him (without, however, a recogniz;ible description) in 

 the " Tableau Synoptique '' of the species of the genus Hccmatopotu. read 

 before the Socit^le Zoologiqiie de France on February 24, 18'Jl (Bull. Soc. 

 Zool. Fr. loc. cit.), in which the West-African species .'-tyled cordiyera in 

 the paper i*ead thirtetMi days previously is called yuinectisis. Although 

 read lati^r, the paper in the Bull. Soc. Zool. Fr. was actually published 

 some months earlier (certiinly before the end of May IS'.U ) than that in 

 tiie Ann. Soc. Ent. Fr., which did not appear until December 2'!, \^\)\ ; 

 but, as has already bei'u stated, //. yuiincusis, Bigot, is insufliciently 

 characterized. It follows from this that the name cordiyera. Bigot, must 

 lie reserved for t lie West- African sjiecit's and tln\t J f. cordiyera, IVigot, 

 Mem. Soc. Zool. Fr. 1892, p. (i2t), from Bengal, must be renamed. I 

 would propose to term the latter species JlioiuUopota fiuscijrons.
