Approaches the genus Amblycoleus (Chaud.), which is known to me only from the 



■ 





description. Its seems to differ by its less broadly rounded apex of elytra and less 

 dilated tarsal joints. In facies it much resembles Calleida pallidvpennis. One example 



only has been received.

About ninety species of this widely distributed genus have been described. Its head 

 quarters, as far as number and variety of specific forms are concerned, are in Tropical 

 America, a much smaller number occurring in Tropical and Subtropical Africa, Asia, 



# 



and Australia. Three species are found in Temperate North America.
