274 Appendix to the Proceedings 



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

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

 cholica, Fab. non Dej." as a synonym ; but I know not on what 

 grounds this statement was made. 



Var. obliterates, 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 ; 

 margin e laterali intus tridentato, punctis duobus apicem ver- 

 sus albis. 



Long. 5^ lin, lat. 2 lin. 



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

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

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

 and proportionately broad. In Luxerii there are two small 

 oblique whitish spots, near to and parallel with the angular sides 

 of the scutellum, which are wanting in this species ; a longish 

 tear- shaped white spot alongside of the suture, distant from the 

 base about ^rd of the length of the elytra, is also wanting here. 

 In Luxerii there is an oblique triangular spot near the apex, in 

 some examples connected with the margin by a slender band, 

 showing that this is merely a part of an interrupted hooked 

 band. In Lowei this spot is confined to a small round or thread- 

 like dot. The white margin is a good deal broader than in 

 Luxerii, and a blackish violet-coloured edging on the outer side 

 of the white margin is more conspicuous than in that species. 

 The greater extent of the interior obscure space and the want 

 of the small white spots in the middle and towards the base of 

 the elytra, readily distinguish this species from Luxerii. 



I have received four specimens, all of which are constant in 

 the above characters. 



I have named this species after my valued friend, Dr. William
