Australian and Tasmanian Cryptocephalides. 429 



interstices posteriorly. Apex of pivsternum rather widely triangu- 

 larly excised. 



Length 5 mm. 



9 . Differs in being larger with the antenna? much shorter and 

 thinner and the second joint not at all transverse ; the head 

 is smoother with smaller punctures and the median line less 

 deeply impressed ; the fourth segment of the abdomen is hidden 

 across the middle ; apical fovea large and deep, with feeble lateral 

 extensions. 



Length 6-7 mm.

The colour of the under-surface and legs (independently 

 of sex) varies greatly, in some specimens these parts are 

 almost entirely testaceous, in others they are almost 

 entirely deep black ; in one specimen the antennae (except 

 for parts of the second, third and fourth joints) are entirely 

 black, in this specimen also (a $ ) the dark facial line is 

 connected with the antennae so as to appear something like 

 a Y. its prothorax is blackish, with the sides and several 

 obscure discal spots testaceous, the sutural marking instead 

 of being narrow and confined to the suture itself gradually 

 widens out so that near the apex (but not at the apex itself) 

 it covers about four interstices on each. In several speci- 

 mens the middle of the scutellum is pallid. The middle 

 of the apex of the prothorax is sometimes black. The dark 

 median line of the prothorax varies considerably in width, 

 the spot on each side is sometimes distinct and fairly large, 

 sometimes small and obscure, and occasionally absent. The 

 elytral punctures frequently have a watery appearance so 

 that (to the naked eye) they appear much larger than they 

 really are. The elytral punctures are not alike in any two 

 of the six specimens before me, on two of them only they 

 are very decidedly geminate in arrangement, on one speci- 

 men they are much sparser and larger at the base than 

 in the others. From each shoulder almost to the apex 

 there is a distinct lateral ridge, but this is invisible from 

 above, 



I drew up the description of this species as new, but 

 subsequently came to the conclusion that it was really 

 Cryptocephalus crassicornis, Chp., of which an unique 

 male only (and without exact locality) was known to 

 Chapuis.
