distance in the field. In collecting in January (1920) in the 
Santa Rita Mountains of southern Arizona, I camped at four 
thousand feet among trees on which nubila galls were common. 
A mountain storm had banked these evergreen oaks with wet 
snow, offering a background against which the wine-purple 
galls appeared too fantastic to be real anywhere but in the 
enchanted lands of our Southwest. 
The galls of the Arizona varieties probably appear early in 
the summer ; they are full-grown by September, and the adults 
probably mature in another month or so. The insects, how- 
ever, do not emerge until late in December or in January, 
during a season of cold weather and snow. Perhaps the more 
southern, Mexican variety, incompta, has a different life 
history. 
While nubila is common in Arizona south of Globe, it has 
not yet been recorded from north of there or from New Mexico. 
If must be very rare in these latter regions if it occurs in them 
at all. 
While the hairy gall of this species appears superficially 
different enough from the galls of most Cynips , it is nothing 
but a villosa gall with the spines much lengthened. The spines 
are inserted on the surfaces of the two in the same way, in 
two varieties of nubila they are enlarged basally, quite as they 
are in villosa, and in both species they are surrounded basally 
by peculiar, short, crystalline hairs. The resemblances are so 
striking that, once having seen them, one wonders why they 
are not apparent at first glance.
