entirely bare, a few hairs on the sides of the penultimate segment. 



The galls of this species measure from 3 to 9 mm. in 

 diameter, and occur in dense clusters along the midvein of only 

 the largest grown leaves of the thriftiest shoots of young red 

 oaks (Quercus rubra). These clusters contain from one or two 

 dozen galls up to one hundred or more and extend along the vein 

 of the leaves to the distance of 7 or 10 cm. 



This species was probably described from specimens collected 

 in Waterbury. 



*A. pulchellus Bassett. 



Female : length 2.5 mm. ; black and glistening ; antennae 14- 

 jointed, dark reddish brown, first joint globose, the third and 

 following joints of uniform length ; thorax ovate, punctate, 

 sparsely hairy, parapsidal grooves closely converging toward both 

 the pronotum and the scutel, the foveae of which latter are shin- 

 ing ; legs clear reddish brown ; wing veins pale brown, radial area 

 open, areolet bounded by veins of uniform size, cubitus indistinct 

 and reaching half way to the first transverse vein ; abdomen 

 short, its first segment equal to four-fifths of its entire length, 

 black and smooth. 



The specimen from which this species is described was found 

 ovipositing in the buds of Quercus prinoides, and was probably 

 collected in Waterbury. 

 *A. patiens Bassett. 



Female : length 3 mm. ; head very dark red, hairy and rugose, 

 vertex flattened, antennae 14- jointed, the first joint dark and club- 

 shaped, second joint one-third the length of the first and some- 

 what lighter in color, third equal to the first and second com- 

 bined, fifth a little shorter than the fourth, and the sixth a little 

 shorter than the fifth, the succeeding joints equal in length, all of 

 the joints except the first dusky red or coppery ; thorax and scutel 

 dull red and covered with hair, parapsidal grooves, median lines 

 and lines near the bases of the wings all present, the median lines 

 reaching about one-third the distance from the pronotum to the 

 scutel, scutellar foveae present, not smooth and shining; wings 

 faintly fuscous, the larger veins pale red, the smaller almost color- 

 less, radial area open and broadest in its middle, areolet present, 

 the anterior sides bounded by indistinct veins; abdomen black
