Asphondylia integrifoliae Felt 

 1908 Felt, E. P. N. Y. State Mus. Bui. 124:376 



This species was reared April 15, 1886 from the flowers of Sumac, 

 Rhus integrifolia,in Los Angeles county, Cal. It evidently 

 came from a subglobular, apparently monothalamous flower bud 

 gall some 3 mm in diameter. 



Exuviae. Length 4.5 mm, light brown, the anterior horns short, 

 stout, subcorneal, the dorsum of the third or fourth abdominal 

 segment with a regular row of stout, chitinous spines at the distal 

 third, the basal half sparsely clothed with smaller spines. Terminal 

 segment invisible. 



Female. Length 2.5 mm. Antennae nearly as long as the body, 

 sparsely haired, rather dark brown; 14 segments, the third with a 

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

 subquadrate, the second slender, with a length about four times its 

 diameter, the third a little longer than the second, more dilated, 

 acute distally. Mesonotum dark brown, the submedian lines sparsely 

 fine haired. Scutellum reddish brown with a few apical setae; 

 postscutellum a little darker. Abdomen reddish brown, sparsely 

 and finely haired; ovipositor light reddish brown. Wings hyaline, 

 costa pale brown; halteres yellowish basally, slightly fuscous apic- 

 ally. Legs a variable reddish brown, the tarsi slightly darker; claws 

 long, stout, slightly curved, the pulvilli nearly as long as the claws. 

 Ovipositor one-fourth longer than the body. Type Cecid. 868. 



A number of specimens of this sex were reared by Mr P. H. Timber- 

 lake in early June 19 14 from hypertrophied flower buds of Rhus 

 trilobata, taken near Salt Lake City, Utah, and as the galls 

 are very similar to those from which the above-described female 

 was reared, and the two sexes present many similarities, we have 

 provisionally referred them to the same species. 



Male. Length 2.5 to 3.5 mm. Antennae extending to the fourth 

 abdominal segment, sparsely haired, blackish brown; 14 segments, 

 the fifth with a length about five times its diameter, the terminal 

 segment with a length four times its diameter. Palpi triarticulate, 

 the first segment small, subquadrate, the second broad, with a length 

 three times its width, the third more slender and one-half longer than 

 the second. Mesonotum dark reddish brown. Scutellum reddish 

 brown apically, yellowish basally, postscutellum yellowish. Abdomen 

 grayish brown. Halteres yellowish red, fuscous apically. Coxae 

 slate colored, the legs yellowish brown, the tibiae and tarsi mostly 

 pale straw; claws stout, strongly curved, the pulvilli as long as the 

 claws. Genitalia; terminal clasp segment very short, bidentate 

 apically ;_dorsal plate short, divided, the lobes narrowly oval; ventral 

 plate short, narrowly and triangularly incised and densely setose. 

 Cecid. 1 644.
