are well filled with rounded scales." Evidently Pascoe's specimen 

 was a female in good preservation. 



C. ARANEUS. — •" Carina near the eye obsolete." This, according 

 to Pascoe, is its strongest character, and as it is one sexually and 

 individually variable, it is not worth consideration. 



C. ALBUMINOSUS. — "There is no appearance of scales on the 

 upper surface of this species, which is a very remarkable one, on 

 account of its smooth, somewhat varnished look, including also the 

 spines." Evidently described from an old ^. See notes under 

 " varnishing." 



C. HUMEROSUS and C. funereus. — In the tabulation these are 

 separated by such characters as "Elytra scaly," and "Elytra 

 with a few straggling scales only." The punctures in abraded 

 and perfect specimens of the same species look very different to 

 the eye, and Mr. Pascoe makes a leading feature of the density 

 or otherwise of the scales in his tabulation, evidently assuming 

 that all his specimens were in perfect condition. Another leading 

 and equally untrustworthy character he employs is — " Posterior 

 spines stout, broad at the base," in comparison with " Posterior 

 spines more slender, not so broad at the base." 



C. BREVicOLLis. — Probably described from a female specimen; 

 the width of the prothoi"ax appeal's to be subject to sexual and 

 individual variation, but this is more apparent than real. 



C. MARGiNisPiNis. — Described from a small and well preserved (J. 

 In his description Mr. Pascoe mentions — " Two minute tubercles 

 on each side of the scutellum at the base." In many of my 

 specimens there is an appearance of small tubercles close to the 

 scutellum; they vary in size sometimes even on an individual, and 

 are usually more pronounced in the males. 



C. CAPiTo. — "Scales on the elytra mingled with a sand-like 

 exudation." There appear to me to be two ways to account for 

 this; the mealy exudation (noted under "scales") in greasy or 

 old specimens sometimes rolls up into minute balls which give a 

 sandy appearance to the parts affected; on the other hand, it may 

 actually have been sand. The country about Champion Bay has
