UESQUITE 
A MIRID ( Mel ano t r i chu s mimus Knight (?)) 
Arizona. T. P. Cassidy (May 6): We have had several complaints recently from 
cattle people about the foliage on mesquite dying and drying irp as though 
the tree had blight. The people arc very much concerned, as they depend 
largely on the mesquite foliage for feed until the summer rains occur. 
At Sawyer Ranch a similar situation was reported. The blighted trees were 
spotted through the mesquite breaks and were very heavily infested with 
hoppers; found hoppers on all of the mesquite trees swept, even though 
they did not show signs of blight, but they were not as numerous on the 
nonblighted trees. (Det. by H. G. Barber.) 
AN UNDERWING (Catocaiinae) 
Arizona. C. D. Lebert (May ?.l): Larvae (species undetermined) were found by 
the thousands under the bark of some large mesquite trees in a Phoenix 
yard. The larvae cone out at night, dro v ) from the trees, cover the lawn 
below, and crawl into the home, where they annoy the occupants. When 
disturbed, many of the larvae suspend themselves "by a silken thread from 
the trees. 
OAK . • 
OAK GALL ( Andricus coronus Beut.) 
New York. W. E. Blauvelt (May 2U): A heavy infestation was noted on a few 
specimens of pin oak at Ry*;, Westchester County, on May 10. Most of the 
galls had already fallen to the ground. 
PINE 
EUROPEAN PINE SHOOT MOTH (Rhy acionia buoliana Schiff.) 
New Jersey. J. V. Schaffner (May 22): Recent observations in the northern 
and central parts of New Jersey show that the European pine shoot moth 
is generally distributed throughout this area. In several localities it 
is apparent that the infestations are on the increase. 
New York. W. E. Blauvelt (May ?k): Light- to-heavy infestations in red, 
mugho, and Austrian -fines were observed from May 10 to lo in various 
localities throughout Westchester, Nassau, and Suffolk Counties. Numerous 
larvae were collected but no pupae were found. 
A SAWZLY ( Neodiprion spp.) 
Massachusetts. J. V. Schaffner (May 24): The sawfly reported in 1335 and 1936 
as seriously injuring red pine in plantations in Middlesex County con- 
tinues in outbreak form. Hatching was general on May 7 and on at least 
two plantations the infestation was so heavy that spraying was necessary 
to prevent serious defoliation.
