NO. 1932. EUCERINE BEES OF NORTH AMERICA— COCKERELL. 265 



Genus XENOGLOSSA Smith. 



Type. — Xenoglossa fulva Smith. 



Maxillary palpi five jointed, longer and more slender than in Xenoglossodes, the last 

 joint well developed. The mandibles are bidentate at apex in the male of X. fulva 

 Smith, the type of the genus, as determined from an examination of one of F. Smith 'b 

 specimens. In the similar X. patrida they are simple at apex in the male. They are 

 also simple at apex in male X. mustelina. 



Subgenus. 

 Peponapis Robertson. 



Type — (Xenoglossa) Peponapis pruinosa (Say). Mandibles bidentate at apex in 

 female. Male with first joint of flagellum short.

 at Quirigua, Guatemala, shows that it is a Xenoglossa of the subgenus Peponapis. 

 Third antennal joint of male very short.

In Proc. California Acad. Sci., 1894, p. 118, Fox treated this as a synonym of X.

 and with paler wings, than fulva.
