Genera and Species of Coleoptera. 323 



semblance to some of the (Edemeridae ; its very distinctly five-jointed 

 tarsi, however, independently of other 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 Dasytidae, notwithstanding the 

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

 to the tibiae : in regard to the first, the hp and epistome are so com- 

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

 that, without dissection, their existence can only be assumed ; be- 

 tween this margin and the mandibles there intervenes a sort of 

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

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

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

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

 N'Gami. 



Phenace cedemerina. (PI. XVI. fig. 0.) 

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

 Sab. N'Gami. 



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

 pale-greyish hairs ; head and prothorax shining, dark brown ; scutellimi 

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

 elytra narrow, elongate, nearly parallel, the shoulders rather prominent, 

 substriate, olive-brown, paler as it recedes fi-om the base ; mandibles 

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

 hairy. Length 3| lines. 



OcHOTYEA [Lampyridae]. 



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

 beneath, consti-icted behind. Antennae very short, 12-jointed, the two 

 basal thickened, the rest serrated. Prothorax transverse, narrower 

 than the head. Elj'tra broader than the prothorax, subparallel, shorter 

 than the abdomen. Legs moderately short, all the coxae nearly con- 

 tiguous; tarsi slender. AbdcTmen eight-jointed in the male, the joints 

 gi-adually decreasing in breadth to the apex. 



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

 affinity of the two is apparently with Lticiola, Lap. (ColopJiotia, 

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

 has been removed, but, judging it from what we 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. 



Ochoiyra semiusta. (PL XVI. fig. 7.) 

 O. pallide fulva ; capite prothoraceque piceo-fiiscescentibus. 

 Hub. India (Malabar). 



Pale fulvous yellow, very sparsely covered with gTeyish appressed 



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