albohirtus Crwf. in the U. S. National Museum, and found it 

 considerably smaller and quite differently colored from Craw- 

 ford's species. The following characters of H. albohirtus were 

 noted as distinctive on comparison with pallidellus: Head and 

 thorax yellow-green, almost golden green ; front dull and 

 coarsely granular, vertex shining in contrast ; mesothorax very 

 yellow, shining, with strong, not dense punctures ; area of meta- 

 thorax rugulose, with median impressed line and shining rim 

 (area smaller, apical part hardly sculptured, in pallidellus} ; 

 white hair on apical part of abdomen very long and abundant ; 

 anterior wing about 4.75 mm. long (much less in pallidellus} ', 

 hind tarsi, knees and apices of tibiae clear light fulvous. The 

 color of the wings is about the same in both species. 



Halictus microlepoides sp. nov. 



9 Length 5.5 mm. Bright, metallic blue. 



Face almost round, only the shiny, black, apical half of the clypeus 

 produced below the eyes ; f rons and vertex finely and closely punc- 

 tured, the punctures more scattered on the finely roughened lateral 

 areas of the face; clypeus and supraclypeal area shiny; cheeks very 

 shiny. 



Thorax opaque; the mesopleurae with coarse punctures above and 

 coarse f ovea above the middle ; upper half of the metapleurae with 

 rather strong plicae. Mesonotum with fine scattered punctures and 

 sharp, close and rather coarse lineolations. Basal area of the meta- 

 thorax a little longer than the scutellum, with a low, rounded, faintly, 

 shiny rim extending well laterally; the surface finely lineolate and 

 with rather numerous, strong, reticulate rugae. Tegulae dark testa- 

 ceous, impunctate. 



Wings hyaline, stigma pale testaceous, the nervures darker, costal ner- 

 vure piceous ; second submarginal cell very little smaller than the 

 third. 



Legs black, knees and tarsi dark brown. 



Abdomen almost nude, very shiny throughout, discs of all of the 

 segments with very minute punctures ; the narrow apical margins of the 

 segments dark testaceous. 



Pubescence very scant, pale gray on the legs and under side of the 

 body. 



Habitat. Organ mountains, La Cueva, New Mexico, alti- 

 tude 5300 feet, i (type) 5.5 mm. at flowers of Datura
