This insect, according to Townsend, produces a fleshy, poly- 

 thalamous, tumorlike, twig gall on Atriplex canescens. 

 It was taken May 13, 1892 near Las Cruces, New Mexico. 



Gall. The gall has been described as 12 mm long and 4.5 to 6 mm 

 in diameter. It is smooth, pale greenish becoming more or less 

 reddish when dry. The gall is rather oblong, more or less irregular 

 in shape, fleshy green, tumorlike and occurs on one side of the twig 

 which is more or less surrounded by the gall. The galls are normally 

 bilocular, each cell being 2 by 3 mm in diameter. 



Exuviae. Length 4.5 mm, light brown, the cephalic horns, long, 

 stout, subapically and mesially rounded and finely serrate; dorsum 

 of the third or fourth abdominal segment with a regular row of 

 moderately stout, chitinous spines on the distal third, the basal 

 half sparsely and irregularly clothed with smaller spines; terminal 

 segment with a posterior row of about ten rather weak, chitinous 

 spines, the latero-ventral ones stouter, the basal half with sparse, 

 much weaker spines. 



Female. Length 4.5 mm. Antennae as long as the body, sparsely 

 fine haired, pale yellowish; 14 segments, the third with a length about 

 five times its diameter. Palpi; the first segment short, stout, sub- 

 quadrate, the second rather stout with a length nearly three times 

 its diameter, the third nearly twice the length of the preceding, 

 greatly dilated near the middle and tapering apically to an acute 

 apex. Mesonotum slaty gray, the submedian lines dark gray and 

 sparsely clothed with fine, whitish hairs. Scutellum a variable dark 

 brown, postscutellum yellowish. Abdomen rather thickly clothed 

 with grayish hairs, dark brown. Wings hyaline, costa light brown, 

 subcosta uniting with the margin near the basal third; halteres pale 

 yellowish, basally, yellowish white apically; coxae dark brown; 

 femora, tibiae and tarsi . yellowish white, the distal tarsal segments
