insignificant. Elytra hardly broader at base thau prothorax, but 

 broadening regularly behind; confusedly punctate, in some places 

 the punctures show a tendency to form longitudinal rows, especially 

 towards the sides. Underside', anterior coxal cavities open behind ; 

 legs short ; posterior femora strongly iucrassate ; posterior tibiae 

 short and stumpy, not longer than the corresponding tarsi, 

 broadening towards the apex, where there are two broad blunt 

 spines ; the posterior tarsi do not arise from the ends of the tibiae, 

 and their first segment is equal in length to the following two 

 together ; claws appendiculate. 

 Range. China, Japan, India.

213. Argopistes lamprotes, sp. nov. 



Body strongly convex, rounded. Upper side shining pitchy- 

 black ; lateral edges of pronotum and elytra brown ; underside 

 rich brown. 



Head with vertex, seen under a high power, extremely finely 

 punctate; eyes very large, consequently the interocular space is 

 narrow, but it contains a few deep pits ; frontal tubercles absent, 

 clypeus deeply concave. Antennae extending to a certain distance 

 beyond the base of the pronotum ; first segment long and club- 

 shaped, almost equal in length to the following three together, 

 second thicker and longer than third, fourth also thicker and 

 longer than third ; from the fifth the segments gradually become 

 thicker. Prothorax much broader than long, sides straight but 

 oblique, anterior and posterior lateral angles rounded and each 

 with a seta-bearing pore, front margin deeply but not uniformly 

 concave, the middle portion being somewhat sinuate, posterior 

 margin sinuate at each side and having a central lobe ; surface 

 closely and finely punctate, the lateral brown border being 

 somewhat raised. Scutellum sharply triangular, with surface 

 impunctate. Elytra : the lateral margins of the prothorax and
