New Hex i co R* Middle oro ok (March 11): Mr. Emory reports that many of the 
grape leafhoppers are present. 
PH'T A r ~"~S TO^MJF S"Y 
Massachusetts A. I- Bourne (March 24): There is one other brief item which has 
core to cur attention here, and which ray be of sore slight inter- 
est. Early in February, during; the course of pruning in the vine- 
yard at the College, a' section of cane from a weakened vine was 
brought down to the office as there had been found one or two 
specimens of apparently coleopterous larvae in the case. r 'e 
succeeded in finding a larva and .pupa, which were very evidently 
'coleopterous and which we forwarded to Dr. /. G. Bo'ving for iden- 
tification. He identified this as the larval and pupal stages 
°- Monophylla terminata Say, a cierid which is predacious on cer- 
tain other forms, no-t ao ly ffhym at odes a moen us , and which is report- 
ed as very plentiful, on dry wood attacked by Sinoxylon. Later 
we bred something like 20 adults of Phym at c d e s am eg nus from this 
small section of cane which was scarcely 10 inches long. Still 
later, about the first of March, several specimens of a red- 
shouldered Sinoxylon, Sinoxylon basilare Say, emerged from this 
same section. This is interesting' as giving a record of the 
breeding of two of Say's species from the sare canes, and also 
of the finding of a predacious form of another of Say's species 
frcm the same source. Apparently from our study of" literature 
on the subject both the Phymatodes and Sinoxylon are purely second- 
ary in the nature of their injury, Deing attracted to weakened, 
dying canes in which t.hey hasten the death and decay of the vine. 
CITRUS 
CITFOPhlLUS I EALYBUG (Pseu &o coc cus gahani Green) 
California H. S. Smith (.''arch 19): The so-called citrophilus mealybug is 
spreading ;;itn extreme rapidity in the citrus orchards of southern 
California. This insect was first discovered in 1013 in an or- 
chard at Uplands- For a numoer of years the pest was more or 
less confined tc this area along with an infestation near Pasadena 
ana another in the San Francisco Eay district. L-^ss than two 
years ago , however, an outbreak was found in Orange County and 
since that time it has spread until no"' it covers an area' of 
over 7,000 acres of orchards in parts of which it is doing severe 
damage to the citrus trees. Biological control work is, however, 
being carried en on a large scale and with great success. Much 
inconvenience is experienced by packinghouses and bi-product plants 
on account cf the necessity of restricting the distribution of 
picking boxes and other orchard appliances in an attempt tc pre- 
vent its further uistriuution.
