dorsal or ventral keel; process on outer side of hind tibia bidentate, the anterior 

 tooth about twice as long as the posterior. 



^a&.— Guatemala City, Guatemala, Dec. 1911 {W. M. Wheeler). 

 Very much like Brazilian A', rotundiceps Smith, but distinguished 

 by the narrowed vertex (that of rotundiceps is exceptionally broad) 

 and the pun'ctation of the abdomen. From X. ordinaria Smith 

 it is readily known by the absence of a keel on under side of abdo- 

 men. 



Xylocopa vt^ilmattae Cockerell, ined. 



Guatemala City, Dec. 1911 (W. 21. Wheeler). Exactly like 

 the type.

 to Guatemala. 



Bombus vinifasciatus Smith.

DROSOPHILA REPLETA WOLLASTON. 



By Frederick Ivnab, 

 U. S. National Museum, Washington, D. C. 



A series of this species has been recently received at the U. S. 

 National Museum from Calabacillas, State of Chihuahua, Mexico, 

 through Dr. S. McGibbon, In the course of determination it 

 was found that aithotigh this species is a very widely distributed 

 one, but little has been published concerning it. The species 

 stands in the Aldrich catalogue as Drosophila punctulata Loew, 

 but Becker, in the "Katalog der palaarktischen Dipteren, " vol. 

 4, 1905, makes Loew's species and D. adspersa of Mik synonyms 

 of D. repleta Wollaston, and there seems every reason to accept 

 this synonymy. In justice to Mik it should be added that he 

 himself suspected the identity of his species with Loew's, but 

 he had no means of verifying it.
