 punctured, scutellum small, elytra regularly punctate-striate, the 

 interstices sparingly and finely punctured, their epipleurae broad 

 and concave, legs short , posterior femora strongly incrassate, the 

 second joint of the tarsi very short, prosternum broader than 

 long, mesosternum covered by the metasternum. 



Hab. Si-Oban. 



From similarly coloured species of Sphaeroderma the present 

 insect may be separated by the long basal joint of the antennae, 

 their close approach at the insertion and by the shape of the 

 clypeus.

 ceous, the antennae (the basal joints excepted) black, head and 

 thorax very minutely punctate, elytra closely and finely punc- 

 tured, the base and a narrow transverse band below the middle 

 obscure pale fulvous, the disc testaceous. 



Length 2 lines.

 incrassate , antennae extending to the base of the elytra only, 

 black, the basal joint fulvous, long and slender, second joint 

 very short, fourth and following joints transversely widened, 

 pubescent, gradually narrowed towards the apex, thorax very 

 short, at least three times broader than long, the sides nearly 

 straight, with a narrow margin, anterior angles strongly oblique
