Mr. A.Murray on Coleoptera from Old Calabar. 155 



dentata, strigaque media recurva subinterrupta incumbente, 

 albis ; femoribus subtus rufis. 

 Long. 4-5 lin., lat. l^^-lf lin. 



The specimens I have from Old Calabar differ slightly from my 

 other specimens of vicina, Dej., but not sufficiently to constitute 

 a distinct species. The labrum is more prominent in the 

 Old Calabar species, but that part varies a good deal in form, 

 and particularly in the development of the three teeth in front. 

 In the males they sometimes appear almost entirely wanting. 

 The first joint of the antennse in vicina, Dej., is green. In the 

 Old Calabar species this joint is either wholly brown, or brown 

 below with a virescent tinge above. The white marks on the 

 elytra are broader in vicina than in this variety, and its apical 

 margin of white slopes somewhat parallel with the margin, 

 while in this variety its upper edge is nearly square or parallel 

 with the base; but the breadth, extent and form of the white 

 markings on the elytra vary a good deal in different individuals. 



I obtained a specimen identical with my Old Calabar examples 

 from M. Jekel, under the name of confusa, Gehin ; but I have 

 not been able to ascertain that it has been anywhere described 

 by M. Gehin, whence I presume it is a MS. name, which I 

 have preserved for the variety. M. JekePs ticket bore " melan- 

 cholica. Fab. non Dej.*' as a synonym ; but I know not on what 

 grounds this statement was made. 



Var. ohliteranda, mihi. 



I have two specimens which I also consider as a variety of 

 the above. The white markings on the elytra have here greatly 

 diminished, so that the humeral lunule and middle band have 

 disappeared, leaving only a white spot where they terminated ; 

 the distinct white margin has also been attenuated to an inter- 

 rupted thread along the margin, and it is very little broader at 

 the extreme apex. A more important distinction is that the 

 granulations or punctuations on the thorax are much finer than 

 in the var. confusa, in which they are coarse. 



3. C. Lowei, mihi. 



Capite thoraceque obscure cupreis ; elytris obscure viridi-seneis ; 

 margine laterali intus tridentato, punctis duobus apicem ver- 

 sus albis. 



Long. ^\ lin, lat. 2 lin. 



Closely allied to C, Luxerii, Dej. Dejean's description of 

 Luocerii applies to this species, with the following exceptions : — 

 This is rather larger, being 5;^ lines in length instead of only 4J,
