The only difference of importance between Ccelomera and Monocesta seems to be the 

 very long third joint of the antennae, a constant character. The rather numerous species 

 are also generally of a more parallel form, and often have uniformly fuscous, black, or 

 metallic elytra. 



This genus is confined to Tropical America ; one species is noted by Clark as being 

 probably a native of our country, whence seven others are now known. 



1. Ccelomera cayennensis.

Hah. Panama, Volcan de Chiriqui, Bugaba, David, Tole (Champion). — Colombia 4 ; 

 Guiana, Cayenne x 2 3 4 ; Peeu 4 5 ; Brazil 4 . 



The specimens obtained by Mr. Champion agree in all particulars with those from 

 Brazil contained in my collection. 



2. Ccelomera lanio.

Eab. Nicaragua, Chontales (Belt). — Brazil 1 2 , Rio Grande 3 . 



A single individual before me from Nicaragua seems to differ only in its very large 

 size (7 lines) from the Brazilian specimens contained in my collection. 



3. Ccelomera nigricollis. (Tab. XXVII. fig. 8.) 



Ccelomera nigricollis, Jac. P. Z. S. 1879, p. 785 \ 

 Eab. Costa Rica, Rio Sucio, Cache, Volcan de Irazu x (Rogers). 



The elytra are slightly metallic purple in colour, subdued by the short greyish 

 pubescence ; the head, antennae, and the thorax are black, the latter is scarcely visibly 

 punctured ; the underside and the femora are testaceous. 



* Latreille also gives Xalapa and the island of St. Thomas as localities, the latter possibly in error.
