its into a pulp and carry it away, but the little time I spent in 
erving them was insufficient to determine anything further re- 
cting their habits. Doubtless in this instance the leaves so 
sumed were used in the construction of suitable nests, in which 
deposit the eggs and rear the young of those insects.” 
f this species should ever become seriously destructive (as is 
y unlikely), its injuries could probably be checked by the use of 
pet poison, since the time when it made the attack above de- 
ibed, was after the fruiting of the plant.

'his insect, a green or yellowish slug-worm, which devours the 
ves of the strawberry in midsummer, seems capable of mischief 
serious as any attacking that plant; but it is removed from the 
t rank of strawberrry insects by the fact that it is evidently es- 
ially subject to some undiscovered check upon its multiplication, 
ch prevents its appearance in undue numbers, except at com- 
atively rare intervals. As far as known, it has not usually oc- 
red in destructive numbers for more than two years in succession 
: t;he same place. 
'rom any other strawberry caterpillar, it may be at once distin- 
ffied by the number of its legs, which is twenty-two, including 
three pairs of thoracic legs; while the true caterpillars of the 
lidoptera have never more than sixteen legs, all told. 
LITERATURE. 
his species was first described in 1861, from adult saw-flies cap- 
id in Connecticut,* and again in the transactions of the Ameri- 
Entomological Society for 1867 (p. 232), where its occurrence 
Maine and New York also was reported; but nothing was known 
its early stages, until six years later, when the larva was dis- 
ered in strawberry fields in Illinois and Iowa. Its life history 
. first published by Prof. Riley in the Prairie Farmer, of Chicago, 
May 25, 1867, the article being illustrated by figures of all 
?es but the egg; and brief notes by the same author also appeared 
die transactions of the State Horticultural Society of Illinois for 
t year. In the issue of the Prairie Farmer for June 22, 1867, 
ition is made of the occurrence of the larva on strawberries in 
stern Iowa and Central New York. 
early two years after (January, 1869), the same writer repeated 
substance of the preceding accounts in the American Entomolo- 
; and notes upon it, drawn from the same sources, were also 
>n in Packard’s Guide to the Study of Insects (1869), and in the 
rd Eeport of the Ontario Entomological Society (1872). In the 
i irth Report of that Society, published the following year, the first 
earance of this insect in the strawberry fields of Canada, was
