 Astylus subgriseus, Pic, L'Echange, xvii, p. 35 (1902). 



$ . Moderately elongate, shining, thickly clothed with 

 rather long, adpressed, cinereous pubescence intermixed on 

 the upper surface with long, erect, black, bristly hairs ; 

 nigro-aeneous or nigro-caeruleous, the basal joints o£ the 

 antennae partly red, the elytra with three narrow luteous 

 stripes — one near the suture and extending along it at the 

 tip, one running down the disc to the middle, and narrowing 

 from the base, and one marginal, complete; the head and 

 prothorax closely, very finely punctate, with coarser punc- 

 tures intermixed, the elytra roughly punctured. Head well 

 developed behind the eyes ; antennae moderately long. 

 Prothorax a little broader than long, strongly rounded 

 at the sides, and much narrowed behind. Elytra moderately 

 elongate, subparallel, somewhat abruptly and obliquely 

 narrowed at the tip, the apices narrow, the sutural angles 

 sharp. Lees long; anterior and intermediate tibiae curved ; 

 anterior trochanters drawn out into a long, blunt, spii.iform 

 process, which is finely denticulate beneath. Vential seg- 

 ment 5 deeply arcuato-emarginate, 6 elongate, subcorneal. 

 Teoinen with very long lateral lobes, which are subtruncate, 

 slightly incurved, and flavo-ciliate at the tip. Penis-sheath 

 abruptly acuminate at apex. 



Length 6f-7, breadth 2|-3 mm. 

 Hab. Brazil [type], Pernambuco (Gounette). 

 Two males, each with the genital armature protruding. 

 They are provisionally referred to the imperfectly described 

 A. subgriseus, Pic, from Brazil, which is said to have three 

 yellowish vittae on the elytra, the one on the disc not reaching 

 beyond the middle, and the suture black. It is the only 

 species of the genus known to me with a long spiniform 

 process extending outward from the anterior trochanters
