299 Report or THE ENTOMOLOGISTS OF THE 
there has been a notable increase in the number of caterpillars 
in New York and throughout the New England States. 
But little was written about the history of this insect in the 
west previous to 1870, when Dr. C. V. Riley’ mentions its ravages 
during the previous two years in Arkansas, and also states that 
“in many parts of Missouri it has been very destructive during 
the past two summers.” From the statements of Riley, Bruner, 
Murtfeldt and Lugger it appears that the caterpillars have caused 
a similar and probably equal injury from time to time in the 
middle states. ‘The extent of its distribution in the west is not 
definitely known, but it probably occurs sparingly as far west as 
California. 
History iv New York State-——Among the first to write about 
the ravages of the forest tent-caterpillar in this State was Dr. Asa 
Fitch, our first State Entomologist. ‘There are no indications in 
his writings that the insect was considered of especial economic 
importance in this State during the first half of the present cen- 
tury. He refers to it but twice in his fourteen reports. ‘The first 
reference® was in 1856 in which he states that “ here at the north 
this insect is far less common than the other species” (the apple- 
tree tent-caterpillar, C. americana). In this report and later? he 
considers it a serious pest to the oak, but otherwise of no especial 
economic importance. | . Fieeaes : 
One of the earliest outbreaks in the State of which there is a 
record was in Western New York in 1866 and 1867 when the 
caterpillars occurred in great numbers upon the foliage of both 
forest and fruit trees. In 1886 Dr. J. A. Lintner,” second State 
Entomologist of this State, referred to their serious depredations 
in apple orchards in some sections of the State. During the past 
ten years this insect has attracted much more attention than at any
