and has an entirely yellow thorax. The carinated hind femora is one of the characters 
mentioned by Lacordaire as distinguishing the genus Gambria from Cyphosterna.

A genus hitherto supposed to be peculiar to the United States, whence four species

lowing South-Mexican species is perfectly congeneric, approaching nearest B. ignicollis
