496 Longicornia Malayana. ^ 



being then unknown in our collections. The prothorax 

 of the male varies much in breadth, as is usually the case 

 in exceptional dilatations or projections of parts, but it is 

 strongly and broadly sinuated at the apex, its anterior 

 angles a little rounded, and then dilating into what may 

 be called a broad lobe, which, in the female, is replaced 

 by a stout tooth ; at about midway a notch occurs, but 

 only in the male, and directly below this notch is the 

 infra-marginal spine; from the middle the sides of the 

 prothorax are slightly narrowed to the base.

Dark bronze-brown, more or less spotted with grayish ; 

 head finely pubescent ; prothorax pubescent at the sides, 

 the central line glabrous, very distinct ; elytra strongly 

 grooved, the intervals between the grooves forming 

 elevated glossy lines, two or three of which are united 

 on the middle before reaching the apex, the grooves with 

 oblong or linear spots of grayish or ochraceous tomen- 

 tum, the most densely tomentose spots forming two irre- 

 gular and interrupted bands, one before and the other 

 behind the middle, the apices truncate, the external angle 

 with a long spine ; body beneath glossy brown, a single 

 grayish spot on each side of each abdominal segment 

 except the last ; legs and antennae brown, slightly pubes- 

 cent. 



Length 9-10 lines. 



The deeply-grooved elytra, each groove filled with a 

 slender line of pale grayish pubescence, contribute to 

 make this species one of the best marked of its sub- 

 family.
