COLLATIA.—CEBRENIS. | 149 
Hab. Mexico (Bilimek, Mus. Vind. Ces.). 
This species differs from the two preceding in the acutely pointed and forwardly- 
directed lateral angles of the pronotum. In most other respects it is closely allied to 
C. emarginata. | 
NIROVECUS. 
Nirovecus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 454. 
One species of this genus is alone known at present, and appears to be peculiar to 
Central America. | 
It is at once distinguished from the preceding genus (Col/atia) by the non-prominent 
lateral angles of the pronotum. From the following genus (Cedrenis) it is separable by 
the spinous condition of the posterior femora. 
1. Nirovecus claviger. (Tab. XIV. fig. 18.) 
Nirovecus claviger, Stal, Otv. Vet.-Ak. Férh. 1859, p. 455. 11; En. Hem. i. p. 199. 1. 
Hab. Mexico (Mus. Berol.1); Guaremata, Capetillo, Duefias (Champion). 
A Guatemalan specimen is figured which entirely agrees with a typical Mexican one 
in the Berlin Museum. 
CEBRENIS. 
Cebrenis, Stal, Stett. ent. Zeit. xxiii. p. 298 (1862); Ofv. Vet.-Ak. Forh. 1867, p. 548. 
This appears to be a truly Neotropical genus; of six described species three are found 
in Central America, two of which, as at present known, are peculiar to that region. The 
posterior femora are unarmed; and the fourth joint of the antenne is incrassated and 
shorter than the preceding.

I have here figured a Guatemalan specimen, Herrich-Schaffer’s figure being some- 
what misleading in not having the pronotal angles prominent. This character also 
applies to the most southern form of the species, as Prof. Berg ° remarks, “ Los angulos 
laterales del pronoto son mas puntiagudos que los de la imagen.” The colour is also 
different.
