460 APHRODISIUM TIBIALE. 



duced in the middle and separated from the disk by an 

 obsolete groove; just before the base the thorax is nar- 

 rowly constricted; the disk is provided with four obsolete 

 tubercles which are arranged two by two; between the 

 posterior pair a short naked keel is present; the sides of 

 the prothorax are strongly angulated. The scutellum has a 

 somewhat elongate triangular shape. 



The elytra are rounded at the shoulders; their lateral 

 margins are sinuate, the sutural ones dehiscent from a 

 little beyond the middle which makes the elytra narrower 

 towards the end than at the base ; the apices are rounded 

 both at the sutural and external angles, more broadly 

 however at the latter ; each elytron is provided with three 

 slightly raised longitudinal lines of which the central one 

 is distinctly curved. 



The under surface of the head is sparsely wrinkled. The 

 prosternum between the anterior coxae is rounded, slightly 

 raised along the middle. The posterior margin of the 5th 

 ventral segment is nearly straight, that of the 6th broadly, 

 not deeply emarginate with rounded lateral angles ; an 

 impressed line runs along the middle of the 6th segment. 



The middle and hind legs are elongate, the femora of 

 the latter do not fully reach to the end of the elytra and 

 the tibiae of the same pair are not compressed but rounded, 

 and slightly constricted at some distance from the apex. 



One male example from the Khasia Hills (Assam) in the 

 collections of the Tring Museum. 



It may be that this somewhat aberrant species is not 

 correctly referred to the genus Aphrodisium. But I do not 

 see any better place for it.
