HahHat. — Central America, West Indies; (Jarolina {Sausaure). 



EtymoUuiy. — Lat., quick. 



The locality [Varolina] assigned to this species by Humbert and 

 Saussure is probably erroneous and no doubt their sj>eciineu was from 

 Mexico or some West Indian island, where, on the same trij), most of 

 their collecting was done. For a description of this spe(;ies see " ]Meiu-
