ORECTOCHILUS BIPARTIÏUS. 65 



sutural angle is a right one. In the cf the anterior legs 

 are stout, the tibiae broadly triangular, with the outer api- 

 cal angle rectangular, not obtuse and not projecting; the 

 tarsus, which is somewhat broader at the base than the 

 tibia, has a shortened oval shape. In the Q the tibia is 

 as usual less broad and the outer angle is very blunt.

This species is closely analogous to Orectochilus margi- 

 nipennis Aube (suhsulcatus Régimb, ^) , but may be distin- 

 guished from it by several characteristics which will here 

 be enumerated: somewhat larger size and somewhat more 

 elongate shape, less ventricose at the shoulders; black la- 

 brum , bordered with red at the front margin , whereas it 

 is entirely yellow in the other species ; the tomentous bor- 

 der of the prothorax is broader, that of the elytra very 

 broad, triangular and dividing the elytra diagonally from 

 the inner portion of the shoulder down to the sutural angle 

 in two portions of about equal size: the inner smooth por- 

 tion showing only four superficial glossy grooves, whereas
