A TUSSOCK MOTH ( Halisidota ingens Hy. 3dw. ) 
Arizona. M. W. Blackman (March. 26): These caterpillars are apparently 
doing serious damage to Ponderosa pine in the Apache National forest. 
The conditions as described seem rather alarming. (Determined "by 
C. Heinrich.) 
WHITE-PINE WEEVIL ( Pissodes strobi Peck) 
Pennsylvania. E. P. Pelt (April 2U) : Some injury to Austrian pine occurred 
in the Philadelphia area, though in New England this insect shows a 
marked preference for white pine. 
A MIDGE ( piplosis inopis 0. S.) 
Connecticut. G. H. Plumb (April 20): A light-to-moderate infestation has 
been observed on Scotch pine in New Hartford. Where the larvae were 
working near the tips of the twigs, the bud clusters appeared to be 
affected. In most cases the lesions were formed about the base of 
a needle, although this was not always true. 
PINE NEEDLE SCALE ( Chionaspis p inifoliae Pitch) 
Connecticut. W. E. Britton (April 2^): Specimens received from' Bristol 
and Wethersf ield, where they were taken on niugho pine. 
Nebraska. M. H. Swenk (April S): On April S some spruce trees in Sioux 
County were reported to be infested with the pine leaf scale. 
WILLOW 
BEAKED WILLOW GALL (Phytophaga rigida O.S.) 
New Jersey. E. P. Felt (April 2U) : Reported as somewhat abundant on 
willows at Palisades Park. 
INSECTS AFPSCTING GREENHOUSE 
AND ORNAMENTAL PLANTS 
CUBAN-LAUREL THRIPS ( Gvnaikothrips uzeli Zimm. ) 
Plorida. J. R. Watson (April 23): Complaints were received of the 
depredations of the Cuban-laurel thrips from Sarasota and Babson Park, 
This is a very serious pest of Picas hiti&a and P. religiosa , making 
the growing of these ornamentals almost impossible. Because the 
thrips curls up the young leaves very tightly it is impossible to get 
at it with an effective spray.
