Sept., 1916.] ACKERMAN : CaRPENTER-BeES OF U. S. 223 



The four intermediate legs and posterior coxae, trochanters and 

 femora, and the two anterior coxae, trochanters and the external sur- 

 faces of the femora are reddish black; legs otherwise yellow; the 

 anterior and intermediate tibiae deeply hollowed ; hairs fulvous ; tibial 

 scale small and black. 



Tvpc. — Location unknown. 



Distribution. — Mexico, Central America, Brazil, Peru and re- 

 ported from Yosemite Valley, California. 



Fimbriata is a neotropical species and the report of its occurrence 

 in California does not seem to be authentic. It has been collected in 

 Mexico and may possibly occur in some of the semitropical regions 

 of the southwestern United States, and therefore I include it in this 

 paper. 



This species is one of the largest forms of Xylocopa. The sexes 

 differ greatly in color. The male is entirely fulvous while the female 

 is entirely black. This wide contrast in color of the sexes seems to 

 be characteristic of many other neotropical species of Xylocopa, espe- 

 cially among the larger forms. The female of fimbriata can be easily 

 distinguished from its closest ally frontalis (01.) by the form of the 

 carinas in front of the posterior ocelli. The males of these two spe- 

 cies, however, resemble each other very closely and are not so easily 

 separated. Fimbriata has been confused with varipuncta (Patt.) 

 from California (which I reduce to a variety of brasilianornm Vdihv. ) , 

 but can easily be distinguished from it.
