Homaspis nigripes, n. sp. 



Distinct from either of the two species described by Davis in its larger 

 size and its largely black legs. 



Female. Length 16 mm. Head transverse, the temples rather broad 

 and strongly rounded; clypeus hardly more than a fourth as long as wide, 

 sparsely punctured and obscurely transversely rugulose; eyes nearly 

 touching the mandibles, parallel within and broadly, weakly emarginate; 

 face nearly twice as wide as long, gibbous immediately below the antennae, 

 flat below, rather coarsely, densely punctured; front impressed on each side 

 above the antennse, scupltured like the face but smooth in the impres- 

 sions; vertex and temples weakly punctured; ocell-ocular and postocellar 

 lines equal and somewhat greater than diameter of lateral ocellus; thorax 

 weakly, densely punctured, notauli rather weak; propodeum with eight 

 areas, five basal and three apical, areola and petiolar area separated, 

 areola polished, the other basal areas weakly punctured and apical areas 

 more or less transversely rugulose; spiracle oval; abdomen slender, its 

 sides very gradually divergent nearly to apex, weakly punctured; first 

 tergite four times as long as apical width, parallel sided before the spiracles, 

 which are placed somewhat beyond the middle, half as wide at spiracles as 

 at apex, dorsal carinae weak, fading out shortly beyond the spiracles, 

 but with a weak median impression extending somewhat further; second 

 tergite about two-thirds as long as first with weak median impression; 

 third and fourth subequal to second, fifth only about a third as long as the 

 others, mostly hidden above; wings without areolet; nervellus broken 

 slightly above middle; hind tibiae somewhat longer than their tarsi and 

 about a third longer than their femora. 



Black with abdomen, except basal three-fourths of first tergite, rufous; 

 clypeus, mandibles, except apices, inner orbits below, irregular spot in 

 middle of face, scape beneath, spot above eye, and scutellum above, yellow; 

 wing bases, tegulae, spots in front and below teguke, front coxae outside, 

 two small spots on middle coxae, front and middle tibiae and tarsi and apices 

 of their femora, and articulation between hind femora and tibiae white; 

 legs otherwise black, the front and middle ones somewhat piceous; wings 

 yellowish-hyaline. 



Type locality: Estes Park, Colo. 

 Type: Cat. No. 19304, U. S. N. M. 



A single specimen taken by F. H. Snow August 1892 and bear- 

 ing the label U. of K. Col. Lot. 153. 



Notopygus scutellatus n. sp. 



In my table 1 to the North American species of this genus this species 

 runs closest to virginiensis Gush., from which it is at once distinguishable 

 by its pale scutellum, postscutellum, and front and middle coxae and its 

 apically black hind tibia; and tarsa] joints.
