ducecl near the middle. Elytra parallel-sided or very slightly

 straight. Length 4 J, width IJmm.

^. Depressed, suboblong, shining. Black; head (except sides 

 behind the eyes, extreme base, and the middle of the base beneath), 

 antennae (except joints 4th-7th), prothorax, apical third of four 

 anterior and tip of posterior tibia?, reddish-testaceous; four 

 posterior tibiae and tarsi piceous, anterior somewhat paler; eyes 

 dark brown. Head moderately densely and shallowly punctate, 

 prothorax more feebly; elytra, abdomen, and undersurface obso- 

 letely punctate. Above with sparse greyish hairs, a few at the 

 base of the head, short on prothorax, longest on elytra and sides 

 of abdomen; undersurface with moderately long straggling hairs, 

 densest on abdominal segments; tibiae moderately densely clothed 

 with whitish pubescence. 



Head transversely suboblong; two wide impressions occupying 

 most of upper surface, separated in front by an irregular elevation 

 (which Yy-hen looked at from behind appears three-pointed), a fovea 

 on each side behind it; eyes moderate, lateral, scarcely prominent; 

 antenna? scarcely reaching posteriar coxae, inserted almost at apex, 

 equidistant at their bases with the middle of the eyes, 1st joint 

 scarcely as long as 2nd-3rd combined; 2nd scarcely shorter than 

 3rd, 3rd-10th subequal, 11th not as long as 9th-10th combined. 

 Prothorax transverse, scarcely as wide as head; apex truncate, 

 base rounded, sides widest in front; anterior angles scarcely, 

 posterior moderately rounded; median line feebly traceable, a 

 transverse impression at base. Scutellum almost concealed by 

 prothorax. Elytra about one and a quarter times as long as head
