writes that he could have obtained any number. The length varies 

 from 2.2-6 mm., of wing the same. On the fore leg I can see only 

 two seta? in any case examined ; on the hind leg they sometimes run 

 as high as ten. The palpi being so much lighter than the antennae 

 is a noticeable character ; the latter are black, the former yellow or 

 brownish. Above the fore coxae is a considerable group of setae 

 extending upward so as to coalesce with the infra-humeral group. 

 Specimens from Idaho were taken in March, April and May. There 

 is also a single female from Pullman, Wash., collected by Mr. C. V. 

 Piper. 



At first sight it would seem that this species is very close to the 

 European P. spinosissima Strobl, to which it will go in Becker's 

 table, but it differs decidedly in wing neuration and tibial cheatotaxy. 



■ 'It urn olympise sp. nov. (Fig. 7.) 



Female. Keddisb yellow ; the front, pleurae, metanoturn and first three abdom- 

 inal segments black. 



" Front broad, black, whitish pollinose and not shining, the lower edge in the 

 projecting center red ; lowest frontal bristles reclinate, moderately divergent. 

 Antennae red, with long, bare, slender, brown arista, which is yellowish at the 

 base. Palpi with strong setae, it and the proboscis yellow Close to the eye, 

 below the antennae on each side, a group of three setae. Dorsum of thorax red- 

 dish chestnut, hardly at all shining, with one pair of dorsocentral and four mar- 

 ginal scutellar bristles; pleurae black, indefinitely reddish along the sutures; 

 halteres wholly yellow. The abdomen presents a very decided contrast in color, 

 as indicated above ; the venter is darker on the apical part than the dorsum. 

 Legs, including coxae, yellow ; tips of tarsi scarcely darker; fore tibiae with one, 

 hind tibiae with two serial setae about the middle, intermediate tibiae with two 

 paired setae near the base; hind femora moderately compressed. Wings large 

 and long, venation exactly as in P. spinipes Coq." (J. M. A. MS.) 



Length 5 mm, of wing 6 mm. 



One female from Olympia, Washington, from Mr. Trevor Kincaid. 

 This is a very distinct and readily recognized species. 



Phora sculellata sp. nov. (Figs. 8 and 11.) 

 Female. Length 3.75 mm. Shining black. Head black, delicately punctured 

 and very shining; front evenly convex, its bristles very stout but not unusually 

 long, all reclinate. Ocelli placed on a slight tubercle. Antennae fuscous, not 

 prominent, palpi rufous, with moderately long bristles. Thorax above piceous 

 black, subshining, covered with fine, brown, recumbent hairs. One pair of dorso- 

 central macrochaetae and four marginal scutellar bristles. Scutellum broadly 

 margined with white behind, the margin extending forward in the middle so 

 that the black basal part is distinctly bilobed. Abdomen broad, shining black, 

 each segment narrowly margined with yellowish white; venter yellowish, hairy, 

 as is also the tip of the abdomen. Legs yellowish, but much in fu seated in places,
