single puncture on each side of apex; elytra with third interstice 

 impunctate. A second specimen (9) has the third elytral inter- 

 stice unipunctate at beginning of apical declivity. (Chaudoir 

 described the el3^tra as with third interstice bipunctate).

M. Tschitscherine has pointed out that I have not referred to 

 the supraorbital punctures of the head, and the marginal punc- 

 tures of the prothorax when describing this species. This 

 omission has had the unfortunate effect of causing him to assign 

 a wrong position to it in his table of f^pecies. I take the 

 present opportunity of noting that these features are normal, viz., 

 two supraorbital punctures on each side of head, and two 

 setigerous prothoracic marginal punctures. It would come into 

 section "22" of M. Tschitscherine's table, having all the char- 

 acters necessary to bring it into that position; it could then be 

 separated from C ivilsoni, Casteln., thus: — 



Prothorax with basal angles obtuse C. porphyriaca. 



Prothorax with basal angles rectangular C. wilsoni. 



Genus Notonomus. 



Since my "Revision of the Genus Notonomus,"* certain infor- 

 mation in regard to the species has been obtained to which 

 attention should be directed : — 



(1) M. Tschitscherine has brought under my notice that, while 

 in Notonomus it is usual for the fifth joint of the tarsi (onychium) 

 to be glabrous beneath, yet in some species this joint is spinulose 

 beneath. This seems a useful observation of a good aid to the 

 identification of some species. I therefore record here the follow- 

 ing as all the species known to me with the onychium {a) spinulose 

 beneath, viz., N. kosciuskianus^ rainbowi, safrapa, colossus, eques,
