Sept., 19 16.] ACKERMAN : CaRPENTER-BeES OF U. S. 215 



Perez probably had reference to some small Central American 

 form according to his description of hinotata. Maidl lists three fe- 

 males of hinotata Perez from Georgia and one male from Texas, but 

 his short description of hinotata does not agree very well with that 

 of Perez. I think that the insects which Maidl calls hinotata are 

 probably synonymous with niicaus Lep.
