No. 22.] HYMENOPTERA OF CONNECTICUT. 403 



the length of the third, third to ninth joints gradually shorter 

 and each larger at the apex than at the base ; thorax hairy, with 

 parapsidal grooves extending from the scutel forward but dis- 

 appearing before reaching the pronotum; in addition to these 

 grooves two parallel lines extending from the pronotum to the 

 middle of the mesonotum, and a median line beginning at the 

 border of the scutel but not extending far forward, the line above 

 the base of the wing distinct and deepest at the scutel, which 

 latter is hairy and without foveae; wings slightly smoky, areolet 

 present, cubitus disappearing before reaching the first transverse 

 vein, the second transverse vein heavy, especially at the base of 

 the open radial area ; legs dark brownish red, the claws bidentate ; 

 abdomen black and shining. 



The galls of this species are globular, sessile and subclasping 

 on the young branches of Quercus hicolor. In form they are 

 somewhat like the Minie rifle balls. The galls are often so 

 densely crowded that they become misshapen. Their surface 

 is finely pulverulent and very hard and dry. The type locality is 

 Waterbury, where females were observed emerging in October 

 and November and were eaten by English sparrows and other 

 small birds as fast as they appeared.

Female: length 4-5.5 mm., mostly dark brown, with dense 

 appressed pubescence on the thorax and along the hind margins 

 of the abdominal segments; legs mostly brown, anterior knees 

 and tarsi reddish ; wings hyaline ; head black, punctate and pubes- 

 cent, palpi reddish, antennae 14-jointed, third joint about as long 

 as the first and second combined, the fourth to sixth gradually 

 decreasing in length, the seven penultimate joints nearly as long 

 as broad, the last joint somewhat longer than the preceding but 

 not as long as the two preceding combined; thorax with its 

 pubescence yellowish, not sufficiently dense to entirely conceal 

 the sculpture, which latter consists of a rather dense punctuation 

 and shallow grooves, two of which extend from the pronotum 

 backward and end about the middle of the mesonotum in a smooth
