each member of the inferior forceps (fig. 113) have the usual 

 pair of mesad projecting spines, the usual pair of dorsal spines, 

 a single very stout ventral, outward projecting spine (b) and a 

 hood surmounted by 40 or 50 palmate spines. Fore tibia with 

 2 or 3 very small setse on outer side; middle tibise with 4 on 

 outer and 4 on inner extensor surface; hind tibia with 12 to 15 

 in 3 irregular rows on extensor surface ; empodium brush-like ; 

 each claw with a single tooth; the second fore tarsal joint about 

 half as long, the fore metatarsus subequal to the tibia in length. 

 Wings hyaline, yellowish tinged, veins yellowish brown ; sub- 

 costal crossvein placed at the base of the small cell, which is 

 oiightly shorter than broad, the distance of the humeral cross- 

 vein to the subcostal crossvein is 1.25 times as great as from 

 the latter to the apex of the costa ; cubitus forks under or 

 very slightly proximad of tip of subcosta; anal vein strong but 

 incomplete. Length of wing 3^ mm. Kingston, R, I., in 

 May (Barlow) ; Lawrence, Kas. (Aldrich). 



7. Sciophila novata n. sp. 

 Male. Length 4 mm. Subshining brownish black, halteres 

 and legs including coxae, yellow, body hairs yellow, basal joints 

 of antenn^K rather paler than the remainder. Fore metatarsus 

 15-16 as long as the tibia. Dorsal plate of the hypopygium 

 (fig. 117) with a slightly emarginate posterior border and with 

 a pair of long setae (s) very sparsely feathered; superior for- 

 ceps acute, much reduced, not produced beyond the dorsal 

 plate; dorsal lobe of the inferior forceps (fig. 119) with 3 long 

 slender but blunt spines (s) and 16 to 18 palmate spines ar- 

 ranged in more or less of a spiral, those outermost much longer 

 and less crowded than the others ; no stout spine on ventral side. 

 Wing yellowish hyaline, veins yellowish ; subcosta ends slightly 

 proximad of the fork of the cubitus; the distance from the 

 humeral crossvein to the subcostal crossvein about 1.25 times 

 as far as from the latter to the apex of the subcosta ; subcostal 

 crossvein is placed close to the base of the small cell which is 

 slightly longer than the R-M crossvein; anal vein strong but 

 incomplete. Ithaca, N. Y., May. Several specimens. 



8. Sciophila inipar n. sp.
