A wide flat species, in general appearance strikingly like 

 python, but apex of elytra tuberculate, tubercles on posterior 

 declivity nearer the summit, eacb shoulder with the outer 

 tubercle the larger instead of the smaller, and the femora 

 somewhat different. The scales very densely clothe the sides 

 of the prothorax ; on the elytra a pale irregular stripe of scales 

 appears to extend from the shoulder to the apex, with an inner 

 dilation near the middle, but this appearance is mainly due to- 

 the comparative sparseness of scales along the middle. 



POROPTERUS LATIPENNIS, U. Sp. 



More or less densely (in places almost glabrous) clothed 

 with scales varying from ashen-grey to sooty, but mostly of a 

 rather light-brown ; tubercles usually with dark fascicles ; 

 legs densely clothed and feebly ringed. 



Head wide ; punctures normally concealed. Ocular fovea^ 

 shallow. Rostrum short, stout, and feebly curved, dilated 

 in front of antennae : apex with dense and clearly-defined punc- 

 tures. Antennae rather stout, inserted about one-third from 

 apex of rostrum ; second joint of funicle distinctly longer than 

 first. Prothorax wide and lightly convex, sides strongly 

 rounded, apically strongly narrowed and produced, apex bifas- 

 ciculate ; median carina absent : subapical constriction feeble. 

 Scutellum absent. Elytra wide, subcordate ; shoulders pro- 

 duced and tuberculiform ; with rows of large, deep punctures, 

 becoming smaller posteriorly ; each elytron with two fascicles- 

 at summit of posterior declivity, one on the second, the other 

 on the third interstice ; third with two other fasciculated 

 tubercles, one about middle, the other at basal fourth ; fifth 

 interstice with two feeble fascicles ; apex feebly bif asciculate, 

 several feeble fascicles elsewhere. Mesosternal receptacle 

 large, medio-basal portion triangular owing to a large exca- 

 vation on each side, apical portion wide; emargination shallow. 

 Abdomen with deep sutures; first segment almost as long as 

 three following combined, its apex incurved to middle, near 

 base with a strong curved groove ; second shorter than third 

 and fourth combined. Legs rather short; femora stout, hind 

 pair extending to tip of elytra; third tarsal joint not very 

 wide. Length, 9 mm.

At a glance apparently close to the following species, but 

 really belonging to the exitiosus group. The rostrum of the 

 type is clothed along the sides to the antennae, but not along 

 the middle, but this may be due to abrasion. Owing to the 

 shape of the receptacle the pectoral canal appears to terminate 

 between the front legs. From some directions the forehead 

 appears to be trisinuate, but only the median sinus is at all 

 distinct.
