70 SECOND YARKAND MISSION. 



parallel, or sinuate (asidioides), behind: scutellum rather large; transverse; angulate, or 

 rounded, behind ; more or less exposed : elytra variable ; more, or less (asidioides), elongate- oval, 

 regularly convex, or depressed on the back (asidioides), more or less strongly declivous behind ; 

 shoulders prominent, or not, the angles distinct, or rounded; diffusely, or seriately, punctured ; 

 in the latter case (asidioides) the punctures are rather large and somewhat oblong, the inter- 

 vals being more finely punctured and alternately feebly costiform ; these punctures are more 

 (asidioides), or less (sometimes only to be detected at the apex), visibly setiferous, the setae 

 being very short, and erect only at the apex : epipleurse continuous with the sides, or (asidi- 

 oides) vertical and marked off from the sides by a well-defined costa, which extends from 

 the humeral angle to just within the apex ; epipleural fold more or less broad, always attaining 

 the humeral angle, which it sometimes reflects, and gradually somewhat curvedly narrowed 

 from the base to near the apex, which it does not quite attain : prosternal process more or less 

 horizontal, generally contracted and more or less vertical behind : intercoxal process truncate, 

 or rounded, in. front. The legs are less robust, and much less scabrous, and more finely 

 pilose, than in Platyscelis : the outer apical angle of the anterior tibiae is not dentiform ; the 

 hind tibiae are straight, or slightly curved (asidioides). The oral organs, and the tarsi (except 

 that the middle joints of the intermediate pair have the basal angles well rounded) do not 

 materially differ from the same parts in the genus Platyscelis. 



$ . All the tarsi simple. Form generally a little more robust and convex, the elytra more 

 rounded at the sides, less nitid, the punctuation, &c., fainter, and the antennae a little shorter 

 and stouter. 



BlORAMIX PAMIRKNSIS. 



$ . Elliptic oval, black, a little nitid, underside and legs brunneous, antennae and palpi 

 rufescent : head finely irregularly punctured in front, coarsely punctured behind the eyes, finely 

 closely muricate punctate and pubescent behind ; broadly rounded in front ; epistoma very 

 short, the suture arched and well impressed ; labrum strongly transverse, very feebly emar- 

 ginate in middle of front margin, the angles broadly rounded, finely and densely punctured : 

 third joint of antennae nearly as long as 4-5 united : prothorax finely, sharply, and somewhat 

 uniformly punctured, gently convex direct from the lateral margins, not closely applied to 

 base of elytra, truncated at base and apex ; sides contracted anteriorly, sub-parallel from before 

 the middle to the base and finely bordered, base and apex still more finely bordered, but only at 

 each side ; hind angles rectangular ; front angles depressed, slightly obtuse : scutellum strongly 

 transversely triangular, densely punctured : elytra scarcely wider at base than base of pro- 

 thorax, shoulders broadly rounded, leaving a distinct open angle between them and the 

 prothorax ; sides very feebly rounded, attenuate and gently declivous behind ; moderately 

 but very distinctly punctured, and showing here and there slight indications of a longitu- 

 dinal seriate arrangement, faintly irregularly rugulose and alutaceous ; thinly hispid at the 

 apex and sides ; epipleurse very narrow, rounded ; the fold broad, gradually curvedly contract- 

 ed from humeral angle to near the apex ; the punctuation, &c., as on the elytra above, but 

 more closely and less cleanly : underside somewhat closely and very finely corrugated, and 

 appearing granulous on the flanks : abdomen finely imbricately rugulose, pilose, first segment 

 with a depression at the middle of its hind margin : intercoxal process rounded in front : front 

 and middle tibiae stout, moderately expanded outwardly, the front being also trigonal, the 

 outer edge sharp and a little sinuous ; hind tibiae larger than the others, and more feebly
