Habitat. — Island of Dominica, West Indies. 



Described from one specimen. 



Type.— Cat. No. 16732, U.S.N.M. ' 



M. cajennensis which has similarly colored legs has the mandibles 

 yeUow at base and no dark hairs on the doi-sum of the mesonotum. 

 The specimens recorded from the West Indies, as this species, are 

 probably M. rufodentata Smith, which, however, may be a synonym 

 of cajennensis. 



MELISSA IMPERIALIS Ashmead. 



Three females and eight males. 



One female. 

 One male. 



XYLOCOPA BRASILIANORUM Linnseus. 

 MEGACHILE FLAVITARSATA Smith. 



MEGACHILE MULTIDENS Fox. 



One female and one male. The latter smaller than the typical 

 specimens and with the median pair of teeth on the apex of the 

 abdomen longer and narrower. This species appears to be close to 

 M. concinna Smith, wliich I have not seen. It differs in the female 

 from the description of that species only in being smaller and having 

 the ventral scopa on the penultimate segment black only at extreme 

 sides. 



MEGACmLE ELONGATA Smitli. 



Two males which differ slightly in the last segment but otherwise 

 agree perfectly. They are, in this one character, slightly different 

 from another male in the collection of the United States National
