72 SECOND YARKAND MISSION. 



reposing on the shoulders of elytra; sides gradually expanded from apex to the middle, 

 thence slightly and sinuately narrowed to the base ; margins irregularly depressed, and 

 transversely rugose ; a faint depression at each side the disc, and another within each hind 

 angle : scutellum small, triangular : elytra a little depressed above, more convex posteriorly 

 and somewhat rapidly declivous behind ; base a little wider than base of prothorax, slightly 

 sinuate, shoulders slightly rounded, sides gradually, but feebly, rounded to the middle, gra- 

 dually narrowed behind, on each elytron eight rows of punctures, more or less effaced at base, 

 sides, and apex ; intervals finely punctured, faintly transversely rugulose, the alternate ones 

 a little convex, especially towards the apex ; very finely and shortly hispid, most distinctly so 

 at sides and apex ; lateral margins costiform : epipleurae distinct ; the fold broad, gradually 

 curvedly narrowed from humeral angle to near the apex, faintly rugulose punctate : last 

 ventral segment with a broad depression in middle of front margin : front tibiae trigonal, 

 gradually, but not strongly, expanded outwardly ; outer edge a little sinuate : hind tibise 

 slightly curved : middle tarsi moderately expanded : intercoxal process truncated in front. 



Length 6 lines. 

 Sind Valley. 



CHIANALTJS, n. g. 



Closely related to Bioramix ; differs in havingthe head longer and narrower, the epistoma 

 distinctly larger, and more produced anteriorly ; the elytra costate and clothed with short 

 erect hairs ; the epipleural fold continued to the apex ; the anterior tibiae finely denticulate 

 down the outer edge, the outer apical angle very strongly dentiform ; the intermediate tarsi 

 very feebly dilated, the joints being distinctly longer than wide. In both sexes the last ab- 

 dominal segment has a semi-circular depression in the middle of the basal margin. 



CHIA.NALUS COSTIPENNIS. 



$ . More or less oblong-ovate, dark brown, head and prothorax still darker, and nitid : head 

 but little wider than long, rather strongly and somewhat closely (except on the crown) punc- 

 tured, finely densely granulose punctate behind ; the front is declivous to the epistomal suture, 

 which is well marked and sub-angulate ; epistoma distinctly produced beyond the base of 

 antennae, broadly rounded anteriorly ; labrum strongly transverse, closely punctured, nearly 

 entire in front, the angles rounded : prothorax transverse, but little convex, sides well rounded, 

 a little uneven ; the margins narrowly irregularly depressed ; finely and not closely punctured, 

 lightly (almost obsoletely) impressed down the median line, usually with a slight foveate 

 depression at each side, and a distinct depression at each side at the base, half-way between 

 the middle and the angles ; apex narrower than base, lightly emarginate, front angles strong- 

 ly depressed, lightly rounded ; base faintly sinuately truncate, hind angles obtuse : scutellum 

 small, transversely triangular : elytra more or less oval, sides more or less rounded, generally 

 widest at the middle, suture costiform, and on each elytron four stout prominent, rounded costae, 

 the second and third united before the apex and continued thence as but one ; running down 

 each interval is also another costa, narrower and much less prominent ; both costae and inter- 

 vals are finely granulose-punctate, and transversely rugulose, and the entire surface is moder- 

 ately densely covered with short erect hairs : epipleural fold broad, very gradually narrowing
