that I have connected thorn with a peculiar blemish on the 
rind of ripening oranges that has "been arousing no re and 
more con-olair.t and speculation. Certain crops suffered 
considerable reduction in grade fron this cause during 1330. 
The injury evidently is becoming increasingly greater. 
E. 0. Fssig (February 24): Hibernating adults are more 
numerous than ever before noted. 
California S. Lockwood (February 26): The grape leaf hopper, has 
evidently wintered very well. The overwintering adults during 
the v<"ar~; days are very readily found in the grasses in the 
vineyards and adjacent roadsides and ditch banks. Unless these 
are checked, cohere ial damage will occur over a large part of 
the San Joaquin Valley. 
PACIFIC BSD SIIDEE (Tctrmychus p acificus McG.) 
California {February 13): For several years this mite 
has oeen becoming increasingly common and disastrous — chiefly 
as n pest of vineyards. It is also a serious menace to various 
deciduous fruit trees and ornamentals. It is my opinion that 
if its aggrego/te damage were computed, it would be shown to 
be the -r.ost costly -oest operating in the northern three-quar^ 
ters of California. To say that it is a major pest is no 
exaggeration. 
3. 0. Fssig (February 24): There are many hibernating mites 
under the bark of grapevines in the San Joaquin Valley.

3. \7. Earned (February 23): Dev.'bcrry plants that had 
evidently been injured ^y the larvae of Aarilus r uf ic ollis 
were received from 'Vinona on February 15. One larva 
tentatively identified by J. M. Lan gston as this species was 
found. 
AH APHID (A mohoro-hora rubi Kalt.) 
- : . v7. Baker (February 12): Ifegs and very recently hatched 
young were found on and close to the buds of evergreen black- 
berries, especially those near the ti~. From one to five 
or six were usually present in each case and the -majority of 
e^gs *ere nore or less concealed in the crevices at the sidef 
of the buds. As the eggs and young appear identical with 
those found on thimble b< rry this is possibly Amahoro^hora 
rubi (Kelt.). In the ease of the thimble berry there were
