PERGANDE — NORTH AMERICAN PHYLLOXERIN^. 235 



the veins the discoidal vein is darkest, and all are bordered with 

 a slight dusky l^shade. The discoidal vein arises slightly nearer 

 the stigma than the base of the wing and its branch near its 

 middle. The stigmal vein is but slightly curved and arises at 

 about the middle of the stigma. Legs rather short. The tarsi 

 provided with the usual pair of knobbed hairs at the tip of the 

 under side of the first joint and at the upper side of tip of the 

 second joint. 



The phpse are orange, their meso-thorax, wing-pads and three 

 last abdominal segments whitish; eyes, and ocelli light cherry 

 brown ; antennae and legs pale dusky. lyarvse and youngest 

 pupae almost colorless.

A few galls belonging to this species, growing along the mid- 

 rib of the leaves of the Pecan, Hicoria olivceforniis , were received 

 July 3, 1877, from Mr. J. Monell, St. lyouis, Mo., which bear a 

 general resemblance to those of Ph. caryescaulis when growing 

 upon the leaves, though more convex above and more conical 

 beneath, where they split into a number of rather long and slen- 

 der pubescent bracts or filaments. The color of these galls, 

 which had partly become quite dry, appears to have been some- 

 what reddish above and green or yellowish beneath. Their shape 

 was more or less oval above and compressed laterally beneath, 

 caused evidently by the drying of the substance. Their largest 

 transverse diameter was 5 to 10 """■ and the vertical diameter 3 to 

 8"""-. 



Apparently the same species of galls on leaves of Pecan was 

 received June i, 1891, from Mr. L. Biedeger, Idlewild, Tex., but, 

 unfortunately, all were empty when received, the contents of 

 most having been destroyed by some Tortricid larva. 



The .same kind of galls were found during August of 1891 to 

 be very numerous on the leaves of young trees of a variety called
