downwards it is not at all convex. The femoral dentition is also 

 different. The clothing is almost exactly the same except that on the 

 elytra there is a feeble tendency for it to become fasciate. 



652. POROPTERUS ALBOSCUTELLARIS n. sp. 



Black, antennae and tarsi more or less diluted with red. Densely 

 clothed with stout scales, varying from white to black, and forming 

 numeroiis fascicles. 



Rostrum moderately stout, sides slightly incurved to middle; 

 coarsely and densely punctate, punctures smaller in front of than 

 behind antenna?, on basal half more or less concealed ; with a fairly 

 distinct median carina in male, but absent or almost so in female. 

 Antennae inserted about one third from apex of rostrum; first joint 

 of funicle distinctly longer than second, second as long as third and 

 fourth combined. Prothorax about as long as wide, sides strongly 

 rounded, base distinctly but not mucli wider than apex; with dense 

 and rather coarse, but partially concealed punctures; with a narrow 

 and almost continuous median carina; feebly tuberculate beneath 

 fascicles. Scutellum small, round and distinct. Elytra about thrice 

 the length of prothorax, but not much wider; with rows of large, 

 somewhat irregular and partially concealed punctures, becoming 

 larger and less concealed towards sides; with feeble tubercles 

 beneath fascicles, those at summit of posterior declivity larger than 

 any of the others but still small; with a few granules scattered 

 about. Under surface with dense and rather coarse but more or less 

 concealed punctures. Hind femora extending to apex of elytra. 

 Length 8-10 J /2 mill.

The posterior declivity is quite as abrupt as in zopJierus, but the 

 species is wider than that one, or any other member of the antiqiius 

 group (to which it belongs). Di general appearance it is much like 

 communis, and other species of the Uthodermus (varicosusj group, 

 but all the species of that group have the scutellum apparently or 

 really absent. 



The bulk of the scales are of a dull smoky brown, but sometimes 

 have a decided reddish tinge, those forming the fascicles are usually 

 black or blackish; on the scutellum they are always whitish, and a 

 few white ones are generally scattered about. On the legs and under 

 surface in fresh specimens they are generally prettily variegated, 

 the bulk of the scales usually being more or less ochreous. The 

 rostrum is denselv clothed for about half of its length in the female,
