semblance to sonic of the (Edemeridoc ; itH very distinctly five-jointed 

 tarsi, however, independently of otlier characters, show at once that it 

 can have nothing to do with that family. But there can be no hesita- 

 tion, I think, in referring it to the Dasytida^, notwithstanding tho 

 structure of the mouth and the presence of two well-marked spurs 

 to the tibiae : in regard to the first, the lip and epistomo are so com- 

 pletely hidden by the scarcely prolonged anterior margin of tho head, 

 that, Avithout dissection, their existence can only bo assumed ; be- 

 tween tliis margin and the mandibles there intervenes a sort of 

 cavity, and the latter, not being covered in the usual way by the lij), 

 arc fully exposed almost to their base. My specimen, which is 

 unfortunately, I believe, unique, was taken by the well-known 

 traveller Anderson, in Southern Africa, in the country near Lake 

 N'Gami. 



Phenace oedemerina. (PI. XVI. fig. 6.) 

 P. gracilis, fuscescens, parce pilosa ; scutello elytrisque pallidioribus. 

 Hah. N'Gami. 



Slender, dark olivaceous brown, sparsely clothed with rather long, 

 pale-gi'eyish hairs ; head and prothorax shining, dark brown ; scutelluiu 

 elongate, rounded below, a depressed longitudinal line in the middle ; 

 elytra narrow, elongate, nearly parallel, the shoidders rather promin«'ut, 

 substriate, olive-bro\A-n, paler as it recedes from the base ; mandibles 

 bright ferruginous ; legs reddish brown ; body beneath dark brown, 

 hairy. Length 3^ lines. 



OcnoTYEA [Lampyridae]. 



Head partially exposed, short, broad in front. Eyes very large, contiguous 

 beneath, constricted behind. Antennas very short, 12-jointed, the two 

 basal thickened, the rest sen-ated. Prothorax transverse, naiTOwer 

 than the head. Elytra broader than the prothorax, subparallel, shorter 



^ than the abdomen. Legs moderately short, all the cox£E nearly con- 

 tiguous; tarsi slender. Abdomen eight-jomted in the male, the joints 

 gradually decreasing in breadth to the apex. 



This genus is allied to Dioptoma (ante, p. 118), and the nearest 

 affinity of the two is apparently with Luciola, Lap. {^Colophotia, 

 Dej.). In the only example I have seen of the former the abdomen 

 has been removed, but, judging it from what wo now see of this, it 

 is probably also exserted, with the same number of segments — the 

 normal number, in fact, in the males. The females of both are un- 

 known. 



Oeliotyra semiusta. (PI. XVI. fig. 7.) 

 (). pallide fulva ; capite prothoraceque piceo-fuscescentibus. 

 /frt6. India (Malabar). 



Pale fulvous yellow, very sparsely covered with greyish nppressod 



hairs ; head pitchy-browni, concave between the eyes, epistome with
