bat are of similar habits, species of each of 





three genera being found upon the male-flowers of palms. Nesotkus, Perkins, from 

 the Hawaiian Is., an insect living: in the wood of Cheirodendron (order Araliaceae), and 

 Sphceracus, Faust, from Brazil, referred to the Cossonina and Cholina respectively by 

 their describers, seem also to belong here.

The sexual characters are so marked in this genus that, as Lacordaire states, the 

 males and females might be taken as belonging to different genera : in the former sex 

 the rostrum is long, almost straight, and opaque, and the antennae are inserted near 

 the tip, and in the female the rostrum is short, slender, curved, and almost

Sent us in numbers from Vera Cruz, these specimens agreeing with others before

 on the disc beyond the middle. The femora are dentate in the male and almost
