Hab. ueigbbourhood of Saiiju, apparently common. 



Encarpaj and clypeus tliickened, the former pyriform, con- 

 tiguous, separated from tbe front by a deep transverse groove ; 

 antenna? filiform, half the length of the body, the second joint 

 short, the third one-half longer than the second, more than half 

 the length of the fourth. Thorax nearly three times as l:)road 

 as long ; sides rounded, slightly converging in front, the hinder 

 angles rounded, the anterior ones obtuse ; disc closely punctured. 

 Scutellum trigonate, shining, impunctate. Elytra rather broader 

 than the thorax, oblong, closely punctured. 



Closely allied to A. ccendea, it may be known from that 

 insect by the relative lengths of the second and third joints 

 of the antenua\
