This is a very remarkable species, the head presenting a good 



deal of the character of that of the genus HyhoThjnclius. The 



crest is formed of a large round tubercle on each side of the 



head between the eyes, while behind and near the centre of the 



forehead there are two small tubercles and considerable inequality 



of surface. The thorax is narrow and very rough and scaly, with 



the dorsal tubercles, on each side of the medial line irregular and 



obtuse, and the sides armed with a strong pointed but not acute 



tubercle. The elytra are rather convex, with perpendicular sides 



and apex. Their sculpture consists of a series of large rugose 



punctures and granules, with three scarcely traceable rows of 



tubercles on each. There are four curious nodular lookins: 



tubercles on the base of the elytra, which project a little forward! 



one is situated on each side of the scutellum, the other two 



between that and the shoulders. There is a narrow white vitta 



on each elytron. 



I captured a male and female of this insect a few weeks ago 

 at Shelley's Flat, near Goulburn ; and curiously enough, about 

 the same time, Mr. Masters found a dead specimen apparently 

 of the same species near Sydney. I have never before seen any- 

 thing like it in any collection.

 This species is about the size of C. Bohemani, but differs 

 from it, and indeed, from all the species I have seen in the ridged 

 and angular appearance of the fourth interstice of the elytra, and
