The antennal joints are proportioned i7iter se almost exactly as 

 in the preceding two species, the antennae as a whole being, how- 

 ever, a trifle more slender than, but of about the same length as, 

 those of C. Vicioriensis ; they are clearly less slender than those 

 of C. antipodum. The puncturation of the upper surface is con- 

 spicuously less flne than in C. Victoriensis. In the male the 

 front tarsi are only gently and the intermediate scarcely if at all 

 dilated. The general appearance is very suggestive of the Euro- 

 pean C. Wilkini, Spence ; but the puncturation is distinctly 

 coarser, and the antenna3 are more slender than in that species.

 This singular insect would have to be referred to the 

 Anisotomides, on M. Lacordaire's arrangement, although its facies 

 is much more that of the Silphides. The species before me has 

 the appearance of a very wide robust Choleva, with extremely fine 

 slender antennae and variegated elytra. The antennae are 

 evidently longer than the head and prothorax together ; all the 

 joints are much longer than wide, and are tliinly beset with 

 longish fine seta? ; of the basal six joints, joint 2 is the stoutest (1 

 being much longer, but scarcely so stout), 3-6 very slender (4-G 

 scarcely, 3 considerably, shorter than 1), 7-11 form a feeble club 

 (being together very little sliorter, but evidently stouter, than 

 3-6 together), and are somewhat equal inte7' se, except joint 8, 

 which is much shorter and evidently more slender tlian the rest 

 (nevertheless, joints 7 and 9 are evidently longer than 10 and 11). 

 The mesosternum is not carinated, althougli it is very convex, and 

 presents somewhat the appearance of coming to a ridge down the
