not much longer than the fourth.

Eight species of this genus have been described *, all Tropical American, ranging, 
like those of Himatidium, from Southern Mexico to Brazil. In Calyptocephala the 
first and second ventral segments are connate, and the mentum is carinate down the 
middle.

Central-American specimens agree with one from Brazil, determined by Boheman, 
in the Baly collection. The species varies considerably in size.

* C. procerula, Boh., from Peru, the type of which is before me, doubtfully belongs to the same genus ; it 
has the third joint of the antenne very little longer than the second.
