L. Has eiian (May 21): Imported cabbage worms have been doing 
Much.' damage on early cabbage. 
DIAMOND- BACK MOTH ( Plutella macul^mnis Curt.) 
"7. G. and L. D. Anderson (May 26): The hymenoxiterous para- 
site Angitia hellulae Vier. (det. R. A. Cushman) has been very 
effective in. controlling this insect. About 90 full-grown 
diamond-back larvae and pupae were collected in the field on 
April 6 and 8; over 95 ioer cent of these wore -parasitized. 
One hyoerparasite Callitula an. (det. C. F. V7. Muesebeck) was 
also reared from this material at Norfolk. 
G. M. List (May 24): The diamond-back moth was found very 
numerous on stocks in a greenhouse at Sterling May 1. Serious 
damage was being done to this planting. 
G. F. Knowlton (May 2): Diamond-back moths are abundant 
upon mustard in several Darts of Box Elder and Tooele Counties. 
HARLEQUIN BUG ( Murgantia histrionica Hahn) 
L. V7. Brannon (May 5): Adults were fairly numerous on scat- 
tered seed kale plants on April 28 at Norfolk. Several egg 
masses were seen. An egg mass which was collected on April 
14 hatched in the inscctary on the 25th. 
E. N. Cory (May 13): More numerous than last year in Talbot, 
Kent, Baltimore, and Prince Georges Counties. 
'.7. A. 'Thomas (May 23): V7c are now witnessing a very definite 
demarcation of broods of this insect at Chadbourn. Ordinarily 
there is no apparent distinction between broods, both adults 
and nymphs being t esent at the same time. 
Ten days 
ago adults were very numerous with practically no nymphs. To- 
day the reverse is true. Few adults can be seen, while thou- 
sands of nym-ohs are observed on the -plants, with hatching still 
in -progress. On some plants these nymphs are so abundant as 
almost completely to cover the foliage and stems. 
J. E. Gill (May 26): They have been abundant all the spring 
on cabbage and collards at Albany. 
L. Haseman (May 21): The harlequin cabbage bug is reported 
as abundant on cabbage, radish, and related crops all over the 
State; it was laying eggs May 20. 
C. Lyle and assistants (May): This insect is quite generally 
abundant and in many cases doing injury to various crucifers.
