272 THE CANADIAN ENTOMOLOGIST 



in the Vienna Museum, collected by Morrison in Colorado, and not previously 

 recognized by me. 



HaJictus arapahoniim Ckll. One male, this sex previously unknown. It is 

 like il. provancheri nearcticus (Vach.), but the abdomen is olive green, with 

 very distinct, faintly ochreous hair bands. Femora light ferruginous, with- 

 out dark markings. 



Halictus pruinosiformis Crawford. One female. 



Halictus riiidoscnsis Ckll. One fem.ale; a rather large form with strongly 

 dusky wings, perhaps separable. 



Halictus galei, n. sp. 9 . Length about 4.5 mm.; head and thorax bluish 

 green, not bright, somewhat shining but not polished; hair of head and thorax 

 white, not dense; head oblong, facial quadrangle much longer than broad; front 

 minutely excessively densely punctured all over, but this does not extend to the 

 region between the ocelli; antennae black, flagellum obscurely reddish beneath 

 toward end ; tegulae dark, not punctured ; wings clear hyaline, nervures and 

 stigma testaceous; mesothorax m.icrcsccpically tessellate and with distinct 

 punctures, about the diameter of a puncture apart; area of metathorax with 

 very irregular strong plica^, and smaller ridges between, the apical part hardly 

 sculptured, its surface microscopically reticulate; legs black; hind spur with 

 three long spines; abdomen black, shining; sides of second segment (especially 

 basally) and all of the following covered with white hair, not so dense as to 

 entirely hide the shining surface, the little hairs beautifully plumose; hind 

 margins of second and following segments narrowly pallid. 



In my manuscript key to the subgenus ChloralictusAhis runs to H. perdi- 

 fficilis Ckll., which it resembles in the hairy abdomen. It dift'ers ivom. perdijjicilis 

 by being very much smaller, with narrower head, and also in coloration. The 

 narrower face, Avith straighter inner orbits, at once separates it from H. ruidosensis, 

 but the peculiarity is not carried nearly so far as in H. longiceps Rob., which I 

 have from Southern Pines, N. C. (Manee). 



Andrena lupinorum Ckll. Comirxn on flowers of Rubus, and also collected 

 from Potentilla. I had only the type cf this fine species. 



Andrena apacheorum Ckll. One fem.ale at Potentilla. 



Andrena prtinorum Ckll. Femiale at Rubus; scape red, clypeus mainly red. 



Melissodes confnsiformis Ckll. One male at Geranium . 



Epeolus hitei Ckll. One male at Geranium; differs from the female b\- hav- 

 ing the first two antennal joints black, and the third red only in part. I had 

 only the unique type of female. 



Anthophora smithii Cress. One male. 



Chelynia elegans Cress. One male at Geranium. 



Osmia armaticeps Cress. One female at Gaillardia. 



Megachile piignata Say. Both sexes at Gaillardia. 



Bombus juxtus Cress. Workers common on Frasera. 



The Rubus referred to is R. melanolasius Focke. 



Summing up the principal results; the morning's collecting gave us one new 

 species, two previously unknown males, one species described in Europe and 

 not before recognized by us, and several specimens of a species of which we 

 previously had only the single type. Also, the M. confnsiformis was the first 

 male in good condition. In connection with Mr. Sladen's recent interesting
