punctiiration of the underside is very sparing, scratcliy, and 

 obscure. 



Port Lincoln ; occasionally in hard fungi on trees. As far 

 :as my experience goes the commonest species of the genus, but 

 I have not found any commonly. 



C (Bqualis, sp. nov. Minus latus ; sat elongatus ; vix pubes- 

 cens ; aequaliter, minus f ortiter, minus crebre punctulatus ; 

 coloribus ut in O. Australi. Long, f 1. 

 The colouring of this little species is exactly that of the 

 preceding, than which it is much more elongate in form, and 

 much more shining. Under a strong lens a very sparing and 

 very short silvery pubescence can be traced, but under an 

 •ordinary lens it appears glabrous. The puncturation is very 

 even over the whole surface, is tolerably strong, but not at all 

 ■coarse or rugose, moderately close, and without any tendency 

 to run in lines. The thorax (which is decidedly transverse) 

 viewed from above appears to be narrowed m something of a 

 curve from the base to the apex ; when examined from the 

 side the lateral edging is seen to be considerably finer than in 

 C. australis and less strongly rounded in outline ; the front 

 margin also is much less convex, not projecting conspicuously 

 over the head. The sculpture of the underside, as in the pre- 

 >ceding, is extremely ill defined and scratchy in appearance. 



C. mimitus, sp. nov. Sat latus ; minus nitidus ; breviter 



pubescens ; subtiliter confertim punctulatus ; f uscus, 



antennis, palpis pedibusque testaceis ; maris capite pro- 



thoraceque lamina transversa erecta instructis. Long. 4- 1. 



This is a wide, very short, species, with elytra not much 



longer than the head and prothorax together. The latter is 



very massive, not much wider than long, contracted in a curve, 



very little from the base to about the middle, and thence 



rather strongly to the front ; the actual lateral margin (which 



is extremely fine) is, as in C. australis, invisible from above. 



The puncturation of the whole upper surface is rugose, fine, 



and very close, without any tendency to run into rows. In 



the male the clypeus is raised in front. into a wide erect lamina, 



emarginate at its apex, about equal in height and width, both 



height and width being about equal to the distance from the 



base of the lamina to the apex of the thorax ; the front of the 



thorax rises into a similar lamina, parallel to, and about equal 



in size with, that of the clypeus.
