CYPHOSTERNA. 
Cyphosterna, Chevrolat, Ann. Soc. Ent. Fr. 1862, p. 756 ; Lacordaire, Gen. Col. ix. p. 188. 
According to Lacordaire the following is the only species really belonging to this 
genus, the others described by Chevrolat belonging probably to the genus Cambria. 
All are unknown to me. | 
1. Cyphosterna quadrilineata. 
Cyphosterna quadrilineata, Chevrolat, loc. cit. p. 757°. 
Hab. Mexico, Yucatan (Pilate +). 
GAMBRIA. 
Cyphosterna, sect. Gambria, Chevrolat, Ann. Soc. Ent. Fr. 1862, p. 760; Lacordaire, Gen. Col. ix. 
p. 189. 
One species only, from Brazil, was referred by Chevrolat to Gambria as a section of 
Cyphosterna. Lacordaire, on the other hand, proposed to limit Cyphosterna to those 
species in which the second ventral segment of the male was abnormally lengthened. 
As he knew only one of Chevrolat’s species which possessed this character, he referred © 
the rest doubtfully to Gaméria, a view which we provisionally follow. The species are 
very rare in collections; two were described by Chevrolat from Mexico and three from 
Brazil and Bolivia. To these I am able to add one from Sonora.
