 Neuroterus fragilis Bass-. '00, p. 335, cf 9 , Q. vire7is (?) Cal. Like majalis but smaller. 



(E) Gall spherical, hemispherical or conical, usually succulent, and consisting of a 

 wall that encloses a chamber in which the larval cell hes free; some of these. galls are 

 loosely attached to the leaf, but more often they are imbedded in the blade. 



(a) Gall globular.

 O. S. '62, Q. falcata, Q. coccinea, Q. tinctoria; 0. S. '65,- Q. tinctoria, Q.falcata, Q. 

 coccinea, Q. imbricaria, Q: ilicifolia; O. S. 70, p. -54, 56, N. Y. Late May: Walsh

 Cook '05, Q. palustris, Ind. Fly, May: Bass. '63, p. 329, Q. ilicifolia, Conn.: Pro- 

 vancher Canada (F. Can. vol. 2, p. 163.) 



Q. rubra, Q. ilicifolia, R. L, Mass. Mid-May. Fly early June. Succulent, globular. 

 The generic position is uncertain: O. S. '61, p. 62, called it Cynips (Trigonaspis f) : 



Mayr '81, placed it in Callirhytis "doubtfully": Ash. '85, Callirhytis: Ash. '87, Cresson 

 '87, Dryophanta. The presence of scutellar pits instead of a furrow and the simple 

 (?) claws are Callirhytis; the smooth thorax, long radial area and shape of the abdo- 

 men favor Dryophanta. (Dnjphanta according to Bassett.) 

 Di-yophanla.
