Rev. H. Clark on Dejean's Genus Coelomera. 321 



Olivier gives C. nigripennis (Fab. Ent. Syst. Em. 2. 14. 9, 

 published 1775 ; Syst. El. i. 480) as a synonym of this species. 

 C. nigripennis, F., is from Surinam. I cannot quite trace the 

 reasons of Olivier's position, but prefer to retain his name with- 

 out hesitation, as being well established, as well as based on his 

 excellent authority.

 ceum, basi nigra ; thorax satis magnus, transversus, lateribus

Amazons. Taken by Mr. Bates. 



9. C. tibialis, Dej. 



C. robusta, paulum ampliata, flavo-fusca, tibiis tarsis et antennis 

 nigro-fuscis ; differt a C. bajula Oliv. in corpore robusto, parum 

 depresso, vix ampliato, in antennis gracilioribus, fuscis (vix nigris), 

 in colore quoque corporis subtus, prothoracis et femorum. 

 Long. corp. lin. 6 ; lat. lin. 3^. 



Probably a distinct species from C. bajida, which is very va- 

 riablejn form and size ; it may be separated as well by its colour 

 (rufo-flavous prothorax and underside) as by the greater attenua- 

 tion of the antennas. 

 Cayenne.

C. parallela, robusta, subpubescens, fusco-rufa, tibiis, tarsis, antennis, 

 fronte capitis et maculis thoracis tribus nigris ; caput longitudina-

 transverse leviter depressus, fortiter punctatus, nigro maculatus,
