cles at base, followed by a row of small granules. Prosternum 

 with an obtuse tubercle in front of coxse; ventral segments sub- 

 nitid, with fine subobsolete punctures. Anterior coxa? separated; 

 anterior femora strongly bent; anterior tibia? moderately strongly 

 falciform, posterior tibiae strongly curved forwards in posterior 

 third, intermediate tibia? with a moderately definite, subapical 

 notch. 



9. Elytra more convex; third interstice with the granules 

 slightly more conspicuous towards the declivity, curved inwards 

 and ending in a short, acute spine; fifth interstice with the 

 granules somewhat larger and more conspicuous than on the 

 other interstices, and larger posteriorly; seventh with a row of 

 three small tubercles at shoulder; prosternal tubercles smaller 

 than in the male; abdomen convex, with scattered punctures; 

 anterior coxa? separated; anterior tibijB almost straight: inter- 

 mediate tibiae not notched; posterior tibiae less strongly curved 

 than in the male. Dimenaions : $, 17x7 mm.; 9, 16x7 mm.

I have given a full description of the male, as, so far as I 

 know, only the original description, which appears to have been 

 based on a female, has been published. I know of no other 

 species with which this one can be compared. The spines, which 

 are outwardly-projecting, are very different from the tuberculi- 

 form granules on C. Bohemani, and do not extend down the 

 declivity, but turn inwards across the base to the large tubercle 

 at the end of the thii-d interstice. The fourth interstice thus 

 bears a spine. In specimens from Beverley, W.A., the spines 

 are smaller near the base, and the spine on the fourth is repre- 

 sented by a small acute granule, the row of spines thus appear- 

 ing interrupted. The tubercles at the base of the seventh inter- 

 stice are also smaller. The female also difiers in having the 

 apical spine hardly larger than the other granules. Possibly 

 the form is distinct, but I regard it as a variety only, as the 

 species seems to vary a good deal in the size of the spines. 



A specimen marked "^4. Dohrni Wat. var. B " was sent to me 

 for examination by Mr. Blair, of the British Museum. It was a 

 large, obese female, with the tubercles larger than usual.
