coming from an inconspicuous blister gall. Polygnotus species 

 was reared, probably from this midge. 



Gall. The blister gall from which this species was presumably 

 reared is yellowish brown, narrowly oval, nearly 4 mm long and 2 

 mm in diameter. 



Female. Length 1.75 mm. Antennae dark brown; 13 segments, 

 the fifth with a length one-third greater than its diameter, the 13th 

 compound, nearly twice the length of the preceding, irregularly 

 rounded. Palpi; uniarticulate. Mesonotum dark brown, anteri- 

 orly and laterally rather thickly clothed with short, golden yellow 

 scales. Scutellum dark reddish brown, postscutellum yellowish 

 brown. Abdomen dark brown, the segments narrowly margined 

 with white, the latter interrupted laterally and mesially. Ovi- 

 positor fuscous yellowish. Wings hyaline, the third vein uniting 

 with costa a little before the basal half, the white discal spot small; 

 halteres yellowish transparent, fuscous subapically; coxae and 

 femora basally fuscous yellowish, the distal portion of femora, 

 tibiae and tarsi dark brown. Ovipositor moderately short, terminal 

 lobes narrowly oval. Type Cecid. ai87oa.

This species was reared from a blister gall on a leaf, presumably 

 aster, taken at Albany, N. Y., March 16, 1907. Polygnotus species 

 and Eurytoma were reared, probably from this midge. 



Gall. Length 2 cm, diameter 1.2 cm. It is a clouded, sooty, 

 blister gall, yellow beneath and dirty whitish above. It looks much 

 like the large blister gall commonly found on aster. 



Female. Length 2 mm. Antennae- dark brown; 16 segments, 

 the fifth with a length scarcely equal to its diameter; terminal 

 segment slightly produced, obtusely rounded distally. Palpi, one 

 somewhat irregular, prolonged segment, swollen distally; face 

 fuscous with yellowish white hairs ventrally. Mesonotum dark 

 brown, the submedian lines rather thickly clothed with golden yellow 

 scales, an inconspicuous patch of the same at the anterior margin 

 and a larger one in front of the humeri. Scutellum a dark brown, 

 postscutellum fuscous yellowish. Abdomen black, the second to 

 eighth segments narrowly margined posteriorly with silvery white, 

 the markings broadly interrupted on the median line; ventral 

 surface suffused with silvery white scales. Wings' hyaline, costa 

 dark brown or black, discal spot yellowish white, the third vein 

 uniting with costa near the basal half; halteres a variable yellowish, 

 fuscous subapically. Coxae and base of femora fuscous yellowish, 

 other portions of legs a nearly uniform dark brown or black; claws 

 rather long, strongly curved, pulvilli as long as the claws. Ovipositor 

 about one-half the length of the abdomen, the distal lobes broadly 

 rounded. Type Cecid. ai36ia.
