Blepharipus Columbia?, n. sp. (Crabronidje.) 

 9 . — Differs from B. iiigricoiiiis in having the posterior tarsi entirely 

 black instead of yellow at the base ; the abdomen is less elongate, and 

 the propodeum has indistinct transverse ridges on the posterior face, and 

 short longitudinal ridges on the base above joining the postscutellum. 

 Habitat. — Ground-hog Basin, Selkirk Mts., B. C. July 24, 1905. 

 Type. — One $ in the collection of Cornell University. 



Spilomena alboclypeata, n. sp. 



$ . — Head and dorsum without the scattered punctures of Foxii ; 

 antennae fuzzy pubescent, the scape lemon-yellow, the pedicel yellowish ; 

 sides of the face, clypeus and mandibles white, tibiae and tarsi pale, 

 otherwise black. 



Habitat. — Revelstoke, Selkirk Mts., B. C, July i, 1905. 



Type. — One male in the collection of Cornell University. 



The male of this genus has not been heretofore known in America. 

 There is a specimen of pusilla male in the collection of the American 

 Entomological Society which differs from the female in having the clypeus 

 and sides of the face yellow and the legs entirely honey-yellow. 



Gonatopus cyphonotus, n. sp. 

 {Kv<\nMvoro% = hump-backed.) 



9. — Black, except scape, pedicel, face, mandibles, trochanters, all 

 coxse beneath, knees, posterior and middle tibiae in the middle, and 

 anterior tibiae and tarsi above, lemon-yellow, rest of legs beyond the 

 swollen part of the femora reddish-yellow. Thorax above and abdomen 

 smooth, polished and shining ; thorax on the side, constriction between 

 the mesothorax and propodeum above, head, and coxae, finely-roughened; 

 propodeum posteriorly a little more coarsely roughened ; hump of thorax 

 without a V-shaped emargination, with an ocellus-like tubercle on each side. 

 Length, 2.5 mm. 



Habitat. — Downie Creek, Big Bend Country, Selkirk Mts., British 

 Columbia. 



Type. — One female in the collection of Cornell University. 



In the type of contortulus, Patton, the entire thorax is covered with 

 a fine transverse striation, more prominent on the propodeum. This is 

 entirely wanting in cyphonotus., and in the latter the constriction between 

 the mesothorax and propodeum is less marked.
