ri/pe.—^o. rA'A, r.s.iN.M. 



Described from 5 specimens — 4 female, 1 male — labeled Utah, .lune 

 20, 1885. In my own collection are many specimens of this species 

 collected by Mr. E. A. Schwarz at American Fork Canyon, Alta, ^lilk 

 Creek, Salt Lake, and Wasatch, L'tah, during the mouth of June, 1893. 



Genus DRYOPHANTA, Forster. 

 J. DRYOPHANTA VESICULOIDES, new species. 



GaU. — In size, color, and general api)earance exactly similar to the 

 gall i)ro(luced by I), vesicvla, Bassett ; I can detect no ditference, but, 

 whereas that species is developed from the buds of Q. alba, this one is 

 developed from the buds of Q. ohtiisiloba. This, in itself, would not be 

 a sufficient reason for considering it a distinct S))ecies, but the galltiy 

 which issues therefrom is very distinct and much smaller. 



Gallfi/. — Fenude. Length, 1.4 mm. Black, i)olished, the autenn;e 

 yellowish, obfuscated toward tii)s; legs yellowish, the coxa- at l>ase, 

 all femora in the middle, and posterior tibiae obfuscated or biownisli. 

 Antenna* 14-jointe(l, long, nearly the length of the body, the third 

 joint one-third longer than fourth, the eight terminal joints short but 

 widened. Thorax short, broad, the parai)sidal groo\"es distinct, sliglitly 

 convei'ginii" posteriorly; pleura smooth; scutellum minutely rugose, 

 rounded, convex, the fovcie small but distinct. Abdomen broader 

 vertically than long, compressed, the ventral valve slightly exserted, 

 testaceous, ^^'ings hyaline, pubescent, the Acins pale yellowish; the 

 cubital cell is almost closed, but the cubitus is very ])ale and indistinct. 



Malr. — Length, 1.8 mm. In colorational detail like the female, but 

 the antenna' are 15 jointed, yellowish, the third joint as long as the 

 two basal joints united, straight, but slightly thickened ajiically; the 

 scutellum ditfers in being smooth an<l i)olished; Avhih^ the abdominal 

 ])etiole is short, and the legs are a little darker or more obfuscated than 

 in the female.
