By J. C. Crawford, 



Associate Curator, Division of Insects, United States National Museum. 



In this paper where both sexes of a species are described, that last 

 described is the allotype. 



Comparative measurements where given in figures were made with 

 the Zeiss binocular microscope equipped with No. 2 eyepieces and the 

 ag objective and an eyepiece micrometer. 



Superfamily APOIDEA. 



EUGLOSSA SURINAMENSIS Linnaeus. 



A single male of this species was taken at Brownsville, Texas, 

 March 23, 1908, on Opuntia lindheimeri (Jones and Pratt coll.). This 

 is, so far as I know, the first record of a species of this family in the 

 United States.

 on the clypeus coarser than on sides of face; above insertion of 

 antennae the punctures finer and closer; process of labrum subtruncate 

 apically and the sides straight; flageUum beyond basal joints fulvous,
