Species of the American Genus Astylus. 363 



triangular one, the sutural tooth slightly overlapping the one 

 on the opposite elytron. 



o*. Metasternum with two compressed conical tubercules 

 in the middle behind. Ventral segment 5 deeply arcuato- 

 emarginate, 6 elongate, compressed. 



Length 6±-8, breadth 2^-3^ mm. ( <$ ? .) 



Bab. Colombia (ex coll. Fry), Magdalena (Mus. Brit.). 



A mainland form of the Antillean A. gorhami, Pic, the 

 markings on the disc of the elytra united into an almost 

 straight vitta, the tooth at the sutural angle in the ? elongated 

 and longer than the outer one, which is also more acute. 

 Three males and two females seen, one female bearing the 

 MS. name Dasytes spinosus, Gruer., and one male, ex Deyrolle, 

 labelled B. amabilis, Dej. The apices of the elytra are 

 truncate in two of the males and rounded in the third. This 

 insect seems to be referable to the species briefly alluded to 

 by Pic under the name A. amabilis : he describes the elytra 

 as having a complete pale discal band and a narrow black 

 tip. His type, from Colombia, was also obtained from 

 Deyrolle, and under the same MS. name. 



35. Astylus octopustnlatus. 



Astylus octojmstidatus, Giorh. Biol. Centr.-Am., Coleopt. iii. 1, p. 330, 

 t. 12. fig. 25 (J). 



$ . Elytra truncate at apex. Metasternum with the small 

 dentiform processes arising from a tumid space in the middle 

 behind. Ventral segment 5 very deeply emarginate, 6 long, 

 compressed. Tegmen simply bifurcate and clothed with 

 long, projecting, blackish hairs at tip. Penis-sheath drawn 

 out into a long point at the apex. 



$ . Elytra deeply emarginate at apex, the sutural and 

 outer angles sharply dentate. 



Hob. Panama, Chiriqui. 



Gorham correctly identified the sexes of this insect, but he 

 overlooked the metasternal dentiform prominences of the <$ , 

 which are wanting in the same sex of his A. vittatus.

 Dasytes lebasii, Dej. Cat. 3rd edit. p. 124 (1837). 



Elongate, narrow, shining, clothed with long, erect, black, 

 bristly hairs intermixed with scattered adpressed cinereous 

 pubescence, the vestiture of the legs and under surface
