PROGEESS EEPOET OX THE EUROPEAN CORN BORER 11 
Hampshire, southern Maine, seven townships in Rhode Island, and 
six scattered townships along the shore line of Connecticut. An 
infestation was also found during the summer of 1923 by scouts of 
the Federal Bureau of Entomology on Fishers Island. N. Y.. which 
is located only about 7 miles offshore from the Connecticut infestation. 
DISCOVERY AND DISTRIBUTION IN EASTERN NEW YORK 
The insect was discovered during the latter part of January, 1919, 
at Scotia. X. Y.. one of the suburbs of Schenectady, by F. V. Oster- 
houdt. in his garden at 223 Sanders Avenue. Mr. Osterhoudt had 
observed unfamiliar worms injuring the sweet corn in his garden 
during the previous summer, and when a popular article on the corn 
borer by R. H. Allen, of the Massachusetts State Department of 
Agriculture, appeared in the Country Gentleman the descriptions 
and illustrations led Mr. Osterhoudt to believe that 'this foreign pest 
was present in his corn. He sent specimens of the larva to C. R. 
Crosby, of Cornell University, who in turn referred them to the 
Lepidoptera specialist, AY. T. M. Forbes. Doctor Forbes recognized 
in these the larvae of P. niihllaUs. a determination which later was 
confirmed by Carl Heinrich/ of the Federal Bureau of Entomology. 
Professor Crosby immediately notified the Bureau of Entomology of 
this discovery on January 29. 1919. 
Subsequent scouting by State and Federal men showed that a 
sparse but widespread infestation existed in the region surrounding 
Schenectady and portions of the Mohawk and Hudson River Yal- 
leys, together with adjacent territory. By the end of 1924, 72 
townships and cities, containing 2,882 square miles, were known to 
be infested in this region. This area also included two adjoining 
townships containing 90 square miles in southwestern Yermont.

DISCOVERY AND DISTRIBUTION IN THE LAKE ERIE SECTION 
During the latter part of September. 1919, an infestation was dis- 
covered on the farm of Alfred Morrison at Xorth Collins. Erie 
County, X. Y.. about 25 miles south of Buffalo and a short distance 
from Lake Erie. Specimens of the larvae were collected by Mr. 
Morrison and sent to Cornell University, where they were identified 
as P. nubilalis by W. T. M. Forbes. This discovery was reported to 
the bureau by E. P. Felt. State entomologist of Xew York. Larvae 
and adults were later submitted to Carl Heinrich. who confirmed the 
determination. 
In September, 1919. an infestation was also found on the farm of 
a Mr. Eagley of North Girard, Erie County. Pa., by D. M. DeLong, 
J. R, Ever, and H. E. Bachus. of the Bureau of Plant Industry, 
Pennsylvania State Department of Agriculture. Specimens of the 
larvae were forwarded to Washington, through P. T. Barnes. 
Subsequent scouting during 1919 and 1920 revealed that the in- 
festation in the Buffalo section was very extensive, whereas the 
Girard infestation was very sparse and confined to a single field; 
in fact no specimens of P. nubilalis were found in the Pennsylvania 
4 Mr. Heinrich has also been responsible for the determination of all other corn-borer 
material mentioned in this review of the occurrence of the pest in the United States 
to date.
