SNOW: DESCRIPTIONS OF NORTH AMERICAN TRVPETID.^. 1 69 



Carphotricha culta Witd. 



Eastern and Western Kansas, Colorado. 



Eurosta solidag-inis Fitch. (PI. VII, f. 5.) 



Numerous specimens showing considerable variation. Eastern 

 specimens (figured), Maine, Connecticut, measure 5 mm. in length, 

 wings, 5 mm. Two of these bear date of May 23. Others from 

 central Illinois are 6.5 to 7 mm. long; wings, 7 mm., with wing pic- 

 ture of a much darker brown than in the foregoing. In nearly all 

 the specimens the large hyaline spot which arises upon the basal 

 posterior border of the wing, extends nearly if not quite to the third 

 vein; in one it stops abruptly at the fifth vein. There are usually a 

 few light spots in the second costal cell. It is well to add to Loew's 

 description (Monogr. I, p. 82) that the hairs of the thorax are golden; 

 the abdominal segments are normally banded with black anteriorly 

 and their pile is yellowish-white, except at the base of the segments, 

 where it is black; the ovipositor while very convex above is flattened 

 ventrally; scutellum often somewhat bilobate at tip. 



Eurosta comma AVied. (PI. VII, f. 3.) 



Four specimens, Connecticut, Virginia (Sept. 23), vary in depth 

 of color and distinctness of wing-drops. In one the hyaline spot at 

 the end of sixth vein is very large. The figure is not dark enough. 



Eurosta fenestrata n. sp. (PI. VII, f. 7.) 



Female. Light brown. Head yellowish; front with weak brownish 

 bristles. Face quite deeply excavated, oral margin projecting and 

 drawn up anteriorly; oral opening of moderate size; palpi brownish 

 at tip, broad and extending past the edge of the mouth. Eyes much 

 longer than wide. Cheeks broad, with one or two stoutish bristle- 

 like hairs. Dorsum of thorax covered thickly with yellowish pollen 

 and glistening yellow pile. The very convex scutellum with two, 

 large, lateral, brown spots and two bristles. Metathorax dark brown 

 with yellow pollen. Pleurae with blackish bristles, a few yellow hairs, 

 and thickly dusted with yellow. Abdomen rather slender, bright 

 brown, mostly yellow pilose, and dusted with the same color, espe- 

 cially on the last segments; a not very distinct pollinose stripe down 

 the middle; each segment at base with a subobsolete darker band. 

 Ovipositor reddish brown, shining, narrowly black at tip, conical, not 

 flattened beneath. The sixth segment is equal in length to the fifth. 

 It is much shorter than the fifth in the female of solidaginis. Legs 

 yellowish-brown, tarsi more yellow, rather long. Wings moderately 

 broad, very obtuse at tip, in pattern of picture resembling conwia but 

 with more hyalinity. Two large clear drops occur in the second
