478 Mr. F. Bates's descriptions of 



p.ioRAMix, n. gen. (Plafj/sceh'des). 



Head strongly transverse : epistoma very short, broadly 

 rounded, or truncated, in front ; prothorax variable, always trans- 

 verse, more or less convex, sometimes a little flattened at the 

 lateral margins, front angles generally depressed, subacute, or 

 rounded, hind angles variable, sides usually rounded in front 

 and subparallel behind : scutellum rather large, transversely 

 triangular: elytra variable, usually elongate oval, regularly 

 convex; diffusedly, or seriately punctured; more or less hispid 

 (generally only at the apex); epipleurte usually continuous with 

 the sides, the fold geiierally Inroad, always attaining the humeral 

 angle and gradually curvedly narroAved from the base to near 

 the apex: legs robust; front and middle tibiae more or less 

 expanded outwardly, the outer apical angle of the front pair 

 not dentiform; the hind straight, or feebly curved. The mouth 

 organs and the tarsi do not materially differ from Platyscelis. 

 The 9 have all the tarsi simple; and are generally more robust 

 and convex; and elytra more rounded at the sides.

Elliptic oval, black, a little nitid, underside and legs dark 

 brown: head finely punctured, closely so, and pubescent behind: 

 prothorax finely vmiformly punctured, gently convex direct from 

 the side margins, not closely applied to base of elytra, sides 

 contracted in front, subparallel behind, hind angles rectangular: 

 shoulders of elytra broadly rounded, sides feebly rounded, 

 gently declivous behind, moderately, but distinctly, punctured, 

 with traces of a longitudinal seriate arrangement, faintly irregu- 

 larly rugulose and alutaceous, thinly hispid at sides and apex; 

 epipleural fold pimctured : underside finely corrugated and 

 appearing granulous, front tibia3 moderately expanded outwardly, 

 and trigonal, outer edge sharp and sinuous. Length 5 lines. 



Pamir, from Sirikol to Panga. 



Bioramix ovalis, n. sp. 



Oval, less elongate and relatively broader than preceding; 

 head more closely and slightly rugosely punctate, not pubescent 

 behind : prothorax more transverse, less convex, sides more 

 rounded, more contracted behind, slightly depressed at the 

 margins, foveolate at each side the middle, punctuation less 

 clean, the angles distinctly more obtuse: elytra more convex,
