gall. The surface is closely pubescent and of a smoky gray color. 

 They are about one-'fourth*of an inch long and one-fifth in diameter 

 across the widest part of the base or rim of the saucer. The leaves 

 to which they are attached are those of Q. alba, I think. 



Gall-flies. — Two females bred from galls sent me by Mr. E. H. King, of Napa 

 City, Cal. Head and thorax brownish red. Eyes and ocelli black. An ten rise 

 dusky brownish red, fourteen jointed, or the thirteenth long and quite distinctly 

 annulate, first and second equal in length, the first clavate, the following gradu- 

 ally shorter to the thirteenth. Thorax microscopally punctate and with a few 

 minute hairs. Parapsides — small and indistinct. Scutellum heavy, coarsely 

 punctate ; fova?. subobsolete, or rather replaced hy two dark, round, hairy, scarcely 

 depressed spots. Abdomen red, approaching black, a very few, widely scattered 

 hairs on the sides of the basal half of the first segment. Legs slender, brownish 

 red. Wings large, hyaline, veins slender, pale brownish red. Radial area open, 

 long and narrow. Areolet well defined by very small veins. Cubitus pale, 

 reaching less than half way to the first transverse. Body .10, antenna" .08, 

 wings .14. 



.Mrs. E. H. King has sent me several Cynipida?, and I take pleas- 

 use in giving her name to this fine species. 



Andricus incertus n. sp. 



No galls. One gall-fly taken ovipositing April 22, 1890, in buds 

 of Q. bicolor. 



Head black, broad. Antennae fourteen jointed, first shining black, clavate, 

 second -very large, ovate, third one-half longer than one and two together, 

 fourth equal to one and two, the following gradually shorter, all dark brown. 

 Thorax black, rough and hairy. Parapsides — -two parallel lines reaching half 

 way from the collare to the scutellum, two widely separated and diverging lines 

 from the scutellum half way to the collare, a short line over the base of each 

 wing, all these very obscure because of the hairiness of the mesonotum. Scu- 

 tellum very small and rough ; fovae extremely minute and almost as lustreless as 

 the scutellum. Abdomen black and shining. First segment two-thirds the 

 entire length. Legs dark, shining brown, nearly black, but a trifle lighter at the 

 joints. Wings hyaline, veins slender. Towards the base of the wings there is 

 a smoky brown spot. Areolet medium size. Eadial area open. Body 13, an- 

 tennas 07., wings 11. 



Andricus ignotus n. sp. 



A single female gallfly of an unknown species appeared in a box 



of fresh galls of A. pruinosus, which, though not differing much in 



size, is certainly distinct from that species, or any other known to me. 



Head black, vertex very finely punctate. Antennae long, fourteen jointed, 

 first large, broad at the apex, but with a remarkably small base, second ovate and 

 placed like an egg in the deep cavity of the first, third nearly twice the length 

 of the first two, fourth one-third, and the fifth one-half shorter than the third, 

 the remaining joints nearly equal. Color one and two clear reddish brown, the
