Head convex, slightly flattened in front, separated from 

 rostrum by a distinct, transverse impression; forehead with two 

 small granules above; supraocular crests conspicuous, upright, 

 projecting forwards and upwards. Rostrum short : upper 

 surface very feebly concave, median line not sulcate; lateral 

 margins not raised. Prothorax (4 x 5 mm.) widely rounded on 

 the sides, disc feebly convex from side to side; subapical con- 

 striction well-marked; median line distinctly impressed, carinate 

 in middle; closely set with rather small, rounded granules: sides 

 granulate above. Elytra (9x6 mm.) suboval, humeral angles 

 rounded; striae moderately deep, punctures slightly transverse; 

 interstices with feeble granules, concealed by clothing, on the 

 central interstices, with more distinct granules towards the sides. 

 Undersurface depressed at base, coarsely punctate, especially on 

 second and fifth interstices. Anterior coxse contiguous; anterior 

 tibiffi moderately strongly sinuate; posterior tibiae with an 

 antero-posterior curvature most marked in upper portion, and 

 with an inward curvature most marked in lower portion; the 

 undersurface of the posterior tibiae distinctly thickened, all the 

 tibiae granulate beneath. 



5. Smaller than male, with narrower prothorax, vith lateral 

 margins ridged; undersurface convex; tibiae simple. Dimen- 

 sions : (J, 13x6 mm. 



Hah.- New South AVales, Victoria, South Australia. 



Type (9) in Macleay Museum. 



The above description was drawn up from a male from Mul- 

 wala (Riverina) in my own collection. With it, I group the 

 majority of New South Wales specimens in my collection; but 

 it is quite possible that some of these will prove worthy of 

 specific rank. The chief variation lies in the size of the elytral 

 granules, and in the degree of curvature of the posterior tibiae. 

 The variety called hrevipes Lea, is included amongst the number, 

 also the species frequently identified as C. morosus Boisd. Much 

 more study and dissection will be necessary before the question 

 of specific distinctness of some of the forms can be regarded as 

 settled.
