Astathes and allied Genera of Longicom Coleoptera. 61 



a large obtuse tubercle on the middle of the disc. Elytra nearly 

 parallel-sided, broadly rounded and unarmed at the apex. Inter- 

 coxal process of the presternum raised in the middle almost to a level 

 with the coxa3 ; mesosternal process vertical in front, turned back at 

 the end to meet the anterior process of the metasternum, which is 

 advanced nearly three-fourths of the way between the middle coxae. 



Type of the genus : Astathes nigricornis, Thorns. 



1. Anastathes nigricornis.

 TetraophthalnuLS nigricornis (Dej. Cat.). 



9 . Reddish -testaceous ; with the elytra somewhat paler towards 

 the apex ; antennae entirely black. Head sparsely and rather feebly 

 punctured ; front slightly concave in the middle between the 

 antennae, convex in its lower part. Antennae reaching about to the 

 apical third of the elytra ; first joint very closely punctured. 

 Prothorax almost equally broad at the base and apex, rather deeply 

 canaliculate at each side behind the lateral tubercle, less deeply in 

 front of it ; the discoidal tubercle extending almost from the base to 

 the apex, strongly and rather closely punctured. Elytra about one- 

 half longer than broad, sparsely and not strongly punctured from the 

 base to a little beyond the middle ; each with two feebly raised dorsal 

 costae. Last ventral segment with an impressed line along the 

 middle, and a faint depression near the apex.

2. Anastathes bijrfagiata, sp. n. (Plate IV, fig. 9.) 



9 . Yellowish-testaceous ; elytra each with a large oval black spot 

 placed transversely just before the middle ; antennae with the first 

 three joints black and glossy, the remaining joints dark brown and 

 dull. Head strongly but not closely punctured ; the front broad, 

 nearly flat above between the antennae, slightly convex below and 

 furnished with a very faint median carina. Antennae scarcely 

 extending beyond the middle of the elytra ; the first joint very 

 closely punctured ; the last eight joints together hardly longer than 

 the first three together. Prothorax almost as broad in front as at the 

 base ; the centro-notal tubercle large and obtuse, extending almost 

 from the base to the apex, strongly and rather closely punctured. 

 Elytra distinctly but not closely punctured, the punctures becoming 

 gradually smaller on the posterior half ; costae almost entirely 

 obsolete. Last ventral segment as long as the three preceding it
