250 Mr. G. R. Waterhouse on some new Coleoptera 



adorned with scales. The legs are bright red. The rostrum is finely- 

 punctured above, and has a short central impressed line at the base, 

 and a large fovea on each side at the base. The head is separated 

 from the thorax by a deep transverse impression, and has a longitu- 

 dinally impressed line and some punctures between the eyes, which 

 are round and prominent. The thorax is subglobose, but contracted 

 and somewhat produced before and behind ; the surface is covered 

 with largish, rounded, glossy tubercles, and there is an indistinct 

 dorsal channel. The elytra are twice as broad as the thorax, very- 

 convex and nearly spherical, but they are produced into a kind of 

 neck in front to meet the thorax, and near the apex they are sud- 

 denly contracted ; at the apex they are pointed. The upper surface is 

 coarsely sculptured, rugose and subtuberculated, and the impressions, 

 though irregular, have a tendency to be arranged in lines. Length, 

 5 to Q\ lines ; width 2 \ to 3 lines. 



The specimens before me are females. They have the antepe- 

 nultimate segment of the abdomen extremely narrow in the antero- 

 posterior direction, and the penultimate segment is large, produced 

 over the last segment and deeply emarginated, and terminating in 

 two spines or pointed processes behind.

The above description, from Erichson, is applicable to the female 

 sex of a species which Mr. Cuming found in great abundance in 

 the Philippine Islands. It is very closely allied to the Ap. pro/a- 

 nus, but differs in form and in sculpturing. It is of a dullish black 

 colour and sprinkled with blue-green scales ; the thorax is globose, 

 and thickly studded with glossy rounded tubercles ; the elytra are 

 thickly, but not very coarsely punctured. In the male, the rostrum 

 is rugosely punctured, somewhat concave at the base, and has a mo- 

 derately broad and deep longitudinal furrow in the centre, and a 

 deepish oblong fovea on each side in front of the eye — the trans- 

 verse furrow at the base of the rostrum runs into this. The head is 

 punctured and has an impressed line between the eyes, which are 

 but little prominent. The thorax is as broad or broader than the 

 elytra — these are nearly cylindrical, or but indistinctly swollen in 

 the middle, from whence they become gradually narrower, and are 

 rounded at the extremity. The abdomen is punctured beneath, and 

 is tolerably well- clothed with minute ash- coloured hairs ; the ter- 

 minal segment is semicircular and rather coarsely punctured. The 

 female has the rostrum convex above, more thickly punctured than 

 the male, and with the longitudinal impression indistinct ; the trans- 

 verse impression at the base is very deep, and suddenly curves in 

 front of each eye to join the lateral fovea, which is deep. The sides 

 of the thorax are boldly rounded, but this segment is narrower than 

 the elytra — these are distinctly dilated in the middle and acuminated 

 behind ; the apex is somewhat produced. The abdomen is convex 

 beneath, and the terminal segment is smooth, glossy, and slightly
