48 PYGIDICRANIDiE. 



well developed, there are probably not two species in the Island 

 of Ceylon, and the author therefore maintains his opinion that 

 Dyscritina Jongisetosa of Westwood and Nannopygia gerstceckeri of 

 Dohrn are identical. 



9 a. Diplatys gerstaeckeri, var. calidasa, Burr. 



This name was proposed for a few females, in the Paris 

 Museum, from Northern India, which resemble the females of 

 B. gerstceckeri in every respect but size. They are a great deal 

 larger, their dimensions being as follows : — 



Length of body 12-12-25 mm. 



„ forceps 1-1-25 ,, 



It is possible that when the male is discovered it will prove to 

 be a yellow variety of the large D. siva.

10. Biplatys ernesti, sp. n. (Fig. 9.) 



Small and slender ; with long dense pale pubescence ; dark 

 fuscous brown. Antennae with 16 segments ; yellowish, rather 

 darker towards the apex, the second segment fuscous. Head 

 black, S \vith the tumid frons not entirely replete, passing fairly 

 sharply into the depressed occiput, but the transverse suture not 

 distinct ; postocular keels rather blunt, shorter than the promi- 

 nent eyes ; posterior margin with a short broad raised space in 

 the middle, divided by the short but distinct median suture ; in the 

 2 the tumid frons is replete, and passes gradually backwards, 

 reaching the posterior margin itself, so that the occiput is not 

 depressed ; the postocular ridges are short, blunt, and obtuse, 

 capped with a low sharp crest ; as usual in the genus, the 

 head is somewhat more quadrate posteriorly in the $ , and the 

 eyes a little smaller. Pronotum dark brown, about as broad as 

 long, decidedly convex anteriorly, gently narrowed posteriorly, 

 slightly longer iu the $ than in the S , the sides straight, the 

 posterior margin truncate, and the posterior angles rounded ; flat 

 margin very narrow. Scutellum brown, relatively large. Elytra 

 ample, broad, blackish brown, paler towards the shoulders. Wings 

 blackish brown. Legs long and slender ; femora distinctly crenu- 

 late, fuscous -, tibise pale, banded with fuscous ; tarsi pale. Abdo- 

 men nearly black, relatively not very slender, very gradually and 

 slightly broadening towards the apex in the c5' , almost parallel-sided 

 in the $ . Last dorsal segment of S quadrate, sloping, scarcely 

 wider than the abdomen ; narrowed in the 5 . Penultimate 

 ventral segment of S quadrate, ample, deeply emarginate on the 

 posterior border, the apex of the emargi nation produced again
