large dark patches on the elytra form isosceles triangles, of which 

 the widest side extends from each shoulder to the 3rd interstice 

 beyond the middle; on perfect specimens the triangles are sharply 

 defined, but when rubbed, these are less distinct. 



Genus A x i o n i c u s, Pascoe. 

 Journ. Linn. Soc, ZooL, x. 1869, p. 455. 

 Eyes large, finely faceted, rather widely separated. Rostrum 

 rather stout and almost straight. Antennce rather stout. Legs 

 rather long; femora feebly grooved and dentate, posterior not 

 extending to apex of abdomen ; tibi?e flat and thin, almost 

 straight, external edge of the intermediate angular. Other 

 characters as in Verissofs. 



This genus is very close indeed to Perissops, but as its type is 

 a well marked and well known species it was not thought advisable 

 to propose its degradation; more especially when it is considered 

 that some of the species now placed in Perissops may not remain 

 there. 



AxioNicus iNsiGNis, Pasc; I.e. No. 5501. 



(J. Elliptic, strongly convex, as deep as wide. Black or 

 brownish-black. Densely and irregularly clothed with short or 

 subelongate scales, varying from snow3'--white to velvety-black. 



Head with, dense but shallow and partially concealed punctures. 

 Rostrum almost the length of prothorax, almost parallel-sided; 

 coarsely and irregularly punctate. First joint of funicle longer 

 than 2nd. Prothorax subconical, no wider than long; with 

 irregular and rather coarse punctures; with several longitudinal 

 waved and obtuse ridges, and a very distinct median carina. 

 Elytra strongly convex throughout, not much more than twice 

 the length and outline continuous with that of prothorax; 

 punctures not very large ; alternate interstices very distinctly 

 raised and usually shining, the 3rd subtuberculate near base; a 

 subtriangular space from the shoulders to the suture beyond the 

 middle with distinct granules, each of which is hollow and bears 

 a seta on its posterior face. Under surface with dense, partially
