The Dinu'oa material was emerging: on January 20 (in 1925). 
My Scott Valley material emerged on January 21 (1926). 
The eggs, layed in mid-winter, give rise to the galls of the 
bisexual incepta in March or April.

bisexual form incepta, new form 
Figures 25, 182 
FEMALE AND MALE. — With the entire antenna in both sexes 
brownish black; the parapsidal grooves distinct to the pronotum; the 
scutellum distinctly smooth, most so anteriorly, the foveal groove smooth 
at bottom. Figure 182. 
GALL. — Closely resembling the galls of the other bisexual forms 
of the species; perhaps more ovoid when fresh, the surface then pebbled, 
bearing low, indefinite ridges which terminate in short, soft spines 
especially near the apex of the gall; on young twigs of Quercus Doug- 
lasii. 
RANGE. — Probably as given for the agamic form of variety vicina 
(fig. 25). The bisexual form known definitely only from Kelseyville, 
California (P. Schulthess coll.). 
TYPES. — 2 females, 8 males, and 11 galls. Holotype and paratype 
females, males, and galls in the Kinsey collection. Galls at the Ameri- 
can Museum of Natural History and the U.S. National Museum. 
Labelled Kelseyville, California; galls April 11 and May 8, 1926; in- 
sects April 21, 1926; Q. Douglasii; P. Schulthess collector. 
The galls collected by Miss Schulthess on April 11 (1926, 
at Kelseyville) were full-sized and contained larvae that soon 
transformed into adults which emerged on April 21. Ten 
adults were recovered from eleven galls, but only two of the 
adults were females. Galls collected from the same locality 
on May 8 (also 1926) were all empty of adults. 
We may expect to find the bisexual forms of two varieties 
of this species on Quercus Douglasii at Kelseyville, since there 
are two agamic insects, echinus and vicina , on that oak in 
that locality. The material here interpreted as the bisexual 
form of vicina is certainly distinct from ribes. The type 
material of ribes came from Oroville, a locality well inside the 
range of form echinus and therefore the probable alternate 
of echinus rather than of vicina. Incepta then should be the 
alternate of the agamic vicina , a conclusion that is also favored 
by the fact that vicina is the more common of the two agamic
