mosa. The insects of this Jacumba material vary somewhat 
in color, averaging darker than the types of dumosae , suggest- 
ing that another variety, perhaps centering in Lower Cali- 
fornia, interbreeds with typical dumosae on the California- 
Mexican border; but our present data do not yet warrant the 
recognition of such a variety. In the San Bernardino area the 
present variety seems to be replaced by another insect, variety 
mista. 
From galls collected by Miss Stanley at Jacumba four in- 
sects emerged (out-of-doors at Bloomington, Indiana) on Jan- 
uary 7 (1927). The type material was collected near Upland 
on February 3 (in 1920), when the galls showed that many 
of the insects had previously emerged, altho other adults 
emerged on that day and still later. All the gall makers had 
emerged from the galls collected later in February at several 
other points in southern California. Thus, emergence is later 
with this insect than with the more northern varieties of the 
same species. 
I have no further data on the life history of dumosae. The 
more northern varieties of the species have two, alternating 
generations, but it is possible that this southern variety has 
but one, an agamic generation each year. Such a condition 
certainly exists among some of the other Cynipidae of south- 
ern California, the young galls appearing in February and 
March a few weeks after the agamic adults have emerged from 
the practically identical galls of the previous generation. 
In addition to the undescribed variety indicated by our 
Jacumba material, galls of still another segregate of echinus 
were collected at extreme southern points in California. It 
occurs on Q. dumosa and its range overlaps that of variety 
dumosae near the town of Alpine.
