This species was reared in numbers August 9-14, 1907 from a 

 large, terminal rosette gall on Solidago canadensis col- 

 lected at Albany, N. Y. Both white and reddish larvae were 

 observed in the gall, which latter presents no marked difference 

 from that of R. capitata. Polygnotus species was reared 

 from this midge. The gall is illustrated on plate 4, figure i. 



Male. Length 4 mm. Antennae distinctly longer than the body) 

 presumably thickly haired; 21 segments, the fifth with a stem three- 

 fourths the length of the basal enlargement, which latter has a 

 length one-half greater than its /•;■ 



diameter and tapering at both 

 extremities. Palpi; the first seg- 

 ment stout, with a length one-half 

 greater than its diameter, the second 

 slender, one-half longer than the 

 first, acute apically. Mesonotum 

 dark brown, the submedian lines 

 sparsely haired. Scutellum. reddish 

 brown, postscutelltrai fuscous yel-

 claws. Genitalia; basal clasp segment short, stout; terminal clasp 

 segment very short, stout, greatly swollen basally; dorsal plate short,

 deeply and narrowly incised. Harpes short, convolute, narrowly 

 rounded.

 abdominal segment, sparsely haired, light brown; 21-22 subsessile 

 segments, the fifth with a length twice its diameter and tapering 

 at both extremities. Ovipositor one-half the length of the abdomen, 

 the terminal lobes long, slightly constricted basally, roundly tapering, 

 otherwise practically as in the male. Type Cecid. ai655.
