-19U- 
on a, trip made May lU, recently hatched and devouring leaves of oak, 
hickory, and elm in farm wood lots of western Ohio. Many of these trees 
near Dayton probably will be defoliated, as the outbreak seems to be more 
intense than that of a year ago. The spring canker worm (Paleacrita yer- 
nata Peck.) is injuring apple trees in unsprayed home orchards in the 
western third of Ohio and is very abundant on many elms in forest and 
dooryard plantings. 
Missouri. L. Haseman (May 26): One of the heaviest outbreaks of cankerworms 
I have seen in many years is showing up throughout central and northeast- 
ern Missouri. The larvae are about half-grown at this time and are strip- 
ping some large elm trees in the Clarksville district. At Columbia they 
are very abundant but not yet seriously stripping trees. 
Kansas. H. R. Bryson (May 25): Very little injury has been caused by canker- 
worms this year. Two or three areas around Manhattan have experienced 
some injury, 
Oklahoma. F. A. Fenton (May 2k) : Cankerworra injury was reported from Okmulgee. 
FOREST TENT CATERPILLAR ( Malacos oma disstria Hbn. ) 
Vermont. J. V. Schaffner (May 2h): Hatching of the forest tent caterpillars 
in Bennington County was general on May 3« The majority of the cater- 
pillars were in the third instar on May 22 and the effect of this group 
feeding was becoming noticeable, particularly on sugar maple. 
New York. R. D. Glasgow (May 22): The forest tent caterpillar, abundant 
again in parts, of eastern New York, is reported to have defoliated some 
pin oak at Chatham. 
South Carolina. F. Sherman ('.May 2^-): Forest caterpillar locally abundant in 
Dorchester and Berkeley Counties, in the eastern section. 
W. C. Nettles (May 21): The forest tent caterpillar was 
causing serious forest tree defoliation about May 1 in the lower part of 
the State. 
Minnesota. J. E. G-rathwol (May ll): Hatching of forest tent caterpillar 
started about May 11. Very abundant. 
GYPSY MOTH ( Porthetria dispar L.) 
Maine. F, ,H. Lathrop (May 19): Larvae were observed hatching from egg clus- 
ters .in the experimental orchard at Monmouth, Kennebec County, on May h. 
Hatching proceeded very slowly during the next 10 days. On May l6 large 
numbers of newly hatched larvae were observed on the experimental trees, 
but little or no feeding had taken place. The insect is unusually abun- 
dant this spring. In southern Maine it threatens to do considerable 
damage in apple orchards located near infested woodland.
