to examine the type material, but I think there can be no 
question of the varietal identity of my own insects. The galls 
are very similar to most anther galls, but bear a scattered 
wool. There are irregular traces of parapsidal grooves near 
the scutellum on some of my males, but not on all of them. 
The occurrence of the type galls on leaves and of my galls 
on aments is merely typical of the gall polymorphism in this 
subgenus, where any young tissue may be attacked, the insects 
showing little specialization in their choices of points of 
oviposition. 
Neiiroterus dubius variety digressus, new variety 
FEMALE. — Mouthparts rufous; the first four (at least) antennal 
segments yellow; mescnotum almost entirely smooth, with distinct, fine, 
continuous, smooth parapsidal grooves extending to the pronotum; scu- 
tellum only in part roughened, quite hairy, the basal furrow smooth; 
legs golden yellow except the piceous coxae; areolet small, but a little 
larger than in other varieties. 
MALE. — As described for the species. 
GALL. — Not known. On Quercus lobata. 
RANGE. — California: Coalinga. Probably occurs thruout the 
range of Q. lobata in Central California. 
TYPES. — 5 females, 1 male, no galls. Holotype female and para- 
type female in The American Museum of National History; paratype 
females and male in the Kinsey collection. Labelled Coalinga (Alcalde), 
California; March 21, 1920; Q. lobata; Kinsey collector. 
The type material was found among a lot of insects from 
ament galls of N euroterus pad ficus, and the galls of digressus 
were not identified, probably because they are small, simple 
cells in the aments, in the accompanying buds, or on the young 
leaves. The insects emerged sometime before the end of 
March in 1920. Altho geographically distant from the range 
of variety dubius, there is no doubt that digressus belongs 
to the same species.
