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 setse 
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 Plafyscelis : 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. 
S . All the tarsi simple. Eorm 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. 
Bioramix pamirensis. 
3 . 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 ; epipleurae 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
