Bees from New Mexico. 13 



slightly greyish, not at all mixed with black ; tegular clear 

 testaceous ; wings nearly clear, costal nervure ferruginous ; 

 abdomen rather broad, but parallel-sided, clothed with 

 greyish-white hair, hind margins of the segments with con- 

 spicuous entire white hair-bands ; apex rounded, irregularly 

 serrulate, not emarginate ; apex of venter with a rather 

 large tooth on each side and a small one in the middle. 



Has the general aspect of M. Townsendiana, from which its 

 front legs and abdominal structures at once separate it. The 

 non-emarginate apex of abdomen allies it with M. manifesto,, 

 but it has not the long median ventral apical tooth of that 

 insect. 



? . — Similar to the male, except for the usual sexual 

 differences. Hind border of scutellum and sides of meso- 

 thorax conspicuously bounded by white pubescence; apical 

 teeth of mandibles very little developed ; ventral scopa white, 

 black on the last segment.

Megachile manifesta, Cress. ; 1878. 



J 1 . — The abdominal bands, described as white by Cresson, 

 are often ochraceous. 



? . — Similar to the male, except in the usual sexual 

 characters, the broader more shovel-shaped abdomen, and the 

 vertex and disk of mesothorax (but not the scutellum) being 

 clothed with black hair. The abdominal hair-bands are entire 

 and very distinct, and the second and following segments 

 have their dark portions clothed with black hair. Ventral 

 scopa white, black on the apical segment and apex of penulti- 

 mate one, white, however, at extreme base of apical segment.
