I . T7V0 bees with jitiexpedcd habits. 



Hal ictus galpiJisice, n. sp. 



Halictns amicus., var. u, Ckll., An. Mag. Nat. Hist., Jan., 1901, p. 

 126. 



A single specimen was collected one evening at Las Vegas, at a 

 flower of Gaura coccinea. I then remarked of it : " Face narrower than 

 type ; possibly a distinct species." It seemed strange that it should be 

 visiting the Ganra, but it did not occur to me that I had a genuinely 

 vespertine bee. On June 22, 1903, at Pecos, I was astonished to see a 

 number of bees busily collecting pollen from the flowers of Galpinsia 

 feudleri (a large yellow evening primrose) after sunset, at 7.30 p. m. I 

 collected some, and found that they were my " Halictns amicus, var. a," 

 which is evidently a distinct species. It is readily known from H. atnicus 

 by the narrower face and more sparsely punctured clypeus. It belongs to 

 Robertson's genus Evylaeiis, and is distinguished from the species in his 

 table by the following combination of characters : Abdomen pruinose 

 with white hair, the thin pubescent fasciae entire ; first segment shining, 

 distinctly but minutely punctured ; hind spur of hind tibia with five teeth, 

 the basal three very long ; enclosure of metathorax minutely caiicellate, 

 semi-lunar, concave, with a raised rim ; stigma large, reddish-honey- 

 colour. The scape is very long ; flagellum dark, faintly brownish beneath 

 at the end. The type specimen is from Pecos. 



Halictns ovaliceps, Ckll., 1898. 



Pecos, N. M., at flowers of Castilleia ititegra, June 23 and 24 (W. 

 P. Cocker ell.) 



This peculiar bee was known only by a single example, taken at 

 Santa Fe. My wife has rediscovered it, and has ascertained that it 

 habitually visits the Castilleia, which has not been considered a bee- 

 flower at all. (Compare Robertson, Trans. St. Louis Acad., 1891, p. 598.)
