the punctures much larger than those on the thorax ; 

 on the first stria they are less regularly placed than 

 on the others; interspaces shining, finely but remotely 

 punctured, convex behind the middle, thickened near the 

 apex, those on the outer disk convex for their -whole 

 length; inflexed limb smooth and shining, impressed on 

 the inner edge with a single row of punctures.

 et profunde punctato; elytris thorace paullo latioribus, sub- 

 parallelis, fortiter punctato-striatis, stria prima confusa ;

Long. 1 lin. Hah. — Western Australia; collected by 

 Mr. Duboulay. 



Head very similar in form to that of C. megalopoides, 

 rather less exserted ; vertex finely transversely rugulose ; 

 front rugulose-punctate, sparingly clothed with short 

 griseous hairs; sutural grooves separating it from the 

 interocular spaces, nearly obsolete, being only visible on 

 their inner portion ; apex of clypeus obtuse, separated from 

 the front by a transverse groove ; antennas about half the 

 length of the body, pale fulvous, six outer joints stained 

 with fuscous ; second joint thickened, more than half the 

 length of the first, third distinctly shorter than the second. 

 Thorax twice as broad as long ; sides straight and parallel, 

 anterior angles thickened, obliquely and narrowly trun- 

 cate ; upper surface transversely convex, deeply and closely 

 punctured, rugulose on the sides ; on either side, near the 

 lateral margin, are a few short griseous hairs, similar to 

 those on the front. Elytra scarcely broader than the 

 thorax, narrowly oblong, sides subparallel ; above mode- 

 rately conxex, strongly punctate-striate, the punctures on 

 the short stria next the suture irregularly placed ; inter- 

 s])aces transversely granulose-strigose, distinctly convex, 

 those near the outer margin subcostatc.
