few species. It will, therefore, be some help to entomologists 

 to add the following notes on the species in question. 



The four following species were wrongly placed under the 

 section "pronotum black." The notes appended are by Mr. 

 Blair except where initialled by the author. 



Ch. puer, Blackb., "has a blue pronotum and would come 

 in your table next to laztus, Blackb., which it very closely re- 

 sembles. The head is black, the eyes sulcate as in Icetus; the 

 prothorax is more strongly and closely punctured with a smooth 

 median line, but not perceptibly different in shape, as one 

 would gather from Blackburn's table. I doubt whether it is 

 really distinct." [A specimen sent seems to me conspecific 

 rather w T ith C '. eremita, Blackb. — H.J.C.] 



Ch. palmer stoni, Blackb., "has a greenish-blue opaque 

 thorax. In your table it would, I think, come next to eyrensis, 

 but it much more closely resembles C. minor, Blackb. With 

 this it agrees in colour, form of head, and general facies, but 

 differs in having, the elytra! puncturation a little stronger, 

 and the tarsi nigro-setose." 



Ch. mundas, Blackb., "has the thorax b rig /^-greenish, 

 subopaque. It runs down next to pulcher, Blackb., from which 

 it may be distinguished by its more elongate form, almost 

 like that of mimus, but more convex, with flat intervals. 

 The elytra are tipped with coppery, unlike either species men- 

 tioned. Mimus, by the way, has the elytra unicolourous, 

 purplish-blue, not varicoloured." 



Ch. minor, Blackb., "has a blue thorax" — "a specimen you 

 return as 'probably hartmeyeri, Geb.' "I sent a specimen 

 to Gebien for verification, and he replies, The species is rightly 

 determined.' Hence hartmeyeri sinks to minor, Blackb." 

 [In the description of minor the colour is stated to be "niger, 

 elytris cyaneis," while in palmerstoni it is given as "niger, 

 elytris coeruleis." — H.J.C] 



[The following three species were wrongly placed under 

 the section "pronotum metallic or coloured." — H.J.C.]: — 



Ch. inconspicuus, Blackb., "has thorax absolutely black. 

 It would run down to your latifrons, but apparently less- 

 strongly punctured. The elytra! sculpture is like that of 

 proxpiciens, Blackb., which is not unlike, though broader." 



Ch. leai, Blackb., "has a black thorax. It would come 

 next to carinaticeps, Blackb., to which it is closely allied. It 

 differs in its more nitid thorax, less-developed ocular carina, 

 more convex elytral interstices, and the finer punctures in 

 the series." 



Ch. proditor, Blackb., has "the thorax black and finds its 

 natural (and tabular) position next to obscurus, Blackb., from 

 which it differs in the convex interstices." [Mr. Blair also
