i.he whole surface of tlie latter being more or less violaceous, 

 very brightly so along the front. The frontal canals are very 

 -distinct, also, from those of any specimen of C. Icevigatum that 

 I have seen ; from the front of the forehead they diverge ior- 

 -svard very strongly (as usual in Carenum), and backward only 

 moderately at first ; they are very deep and run back pretty 

 ■evenly to about the level of the back of the eye, and there they 

 -curve outward and run obliquely for a short distance towards 

 the sides of the neck with scarcely any diminution of depth, 

 finally merging into a shallow ill-defined depression which 

 fades away before reaching the margin; just at the point 

 where they begin to curve outward they are connected, not by 

 Si vague depression, but by a clearly cut fine arched line. The 

 thorax differs very little from that of IcBvigatum except that 

 ihe base is less strongly sinuate, but the proportion of the 

 thorax and el^'-tra is different, the former being distinctly 

 narrower than the latter (as seven to seven three-quarters) 

 whereas in all the Icevigatum I have measured there is no differ- 

 ence between those parts in width. The thickened part of the 

 humeral margin of the elytra is turned over exactly as in 

 IcEvigatum, but is smaller, otherwise the margins are very 

 similar ; on the anterior tibiae the lowest tooth in the exterior 

 ridge above the apical large ones is less visible from a point 

 perpendicular to the upper surface of the tibia than in Icevigatum^ 

 and the topmost tooth is less defined, while the inferior ridge 

 has only seven teeth, which commence at about the same place 

 iis in Icevigatum. I took a single specimen of this insect at 

 "Wallaroo.

A well-marked species. Its elongate elytra (half again as 

 long as together wide), somewhat concave dorsally, point to 

 the probability of its being allied to C. suhplanatum. Bates, 

 which, however, has bidentate anterior tibiae and uusculptured 

 -elytra. The frontal foveae are well defined, and diverge
