80 REVISION OF THE AUSTRALIAN AMARYGMIDES, 



antrorsum angiistato ; elytris niulto magis fortiter (quam 

 C. variabilis, Blessig, fere magis fortiter) seriatim punctu- 

 latis, interstitiis vix subconvexis, tarsis subtus fulvo-setosis ; 

 cetera ut C. lonyipennis. [Long. S-J, lat. 4V lines. 



This species presents one of the difficulties of tabulation which 

 I have found it impossible to exclude in dealing with this genus. 

 It belongs to the aggregate having the following characters in 

 combination — ocular sulci absent, underside not iridescent, tarsal 

 vestiture fulvous. This aggregate I have divided into two groups, 

 in one of which the prothorax is gradually narrowed forward from 

 the base, while in the other that segment is of equal width from 

 the base to the middle. But the prothorax in this species does 

 not seem quite in place in either of those groups, being when 

 viewed from above very little (but still perceptibly) narrowed from 

 the base to the middle and then much more strongly thence to the 

 front. I have with some hesitation placed the insect in the former 

 of the two groups ; if it were regarded as belonging to the second 

 of them, it would stand beside colossus, Blackb., from which it is 

 at once distinguished inter alia by the very much larger punctures 

 of its elytral series. From the Western Australian C. similis it 

 is separated inter alia by its very much more transverse pro- 

 thorax, as well as by the larger punctures of its elytral series. 

 It may be noted that there is a suiall obscure carina close to the 

 inner margin of each eye, and that the anterior inner corners of 

 the eyes are cut very obliquely, so that the space between the eyes 

 narrows considerably hindward — characters which I do not find 

 in any very nearly allied species.
