THE SNOWY TREE CRICKET. 6i 
THE 10 MOTH. 
I tomeri* to Fab. 
Larva 1 of the io moth were found working on cotton at Pari-. Tex., 
in August, 1904. September 8, about a dozen wore found on a single 
stalk of cotton at Cooper, Tex.: one of them had pupated by October 
1. This is a not uncommon species on cotton, but the injury i- only 
local. 
INSECTS AFFECTING THE STALKS. 
THE SNOWY TREE CRICKET. 
(Ecanthus nireus De<i. Fig. 20. ) 
This insect is of little economic importance in the cotton held, being 
beneficial, if anything: hut the fact that the ego> found in the stalks 
in winter have been generally mistaken for those of the boll weevil 
by persons unacquainted with the habits of the latter inject makes 
it of interest. The 
eggs are laid in the 
fall in the stalks of 
cotton and various 
large weeds. They 
are arranged in a 
longitudinal row. 
and form a scar with 
numerous punctures, 
like the scars upon raspberry canes and fruit tree- dig. '21). These 
^gg> hatch in early spring and the young feed upon plant lice. The 
habits of the nymph- have been well described by Prof . C. O. Hough- 
ton." and our observations confirm his statement- regarding the food 
habits, except that we have observed the adults to feed somewhat 
upon the tender portions of the foliage. The young become full 
grown by the middle or latter part of June in Texas, whereas in 
Delaware they did not mature until July 25. In the North there is 
but one generation a year, but there seems to be good evidence that 
two generations occur in Texas. 
Two females were placed in a cage June 12. 1904:, at which time the 
adults were common. A week later it wa- observed that the leaf 
petiole had been eaten until almost severed and the lobes of the Leaves 
had also been attacked for food. July 1 it was found that the under- 
side of the petiole toward the leaf was the favorite feeding point. 
July 8 egos were found deposited in a leaf petiole, sometimes the egg- 
puncture extending through it. The egg- are about 1 by 4 nun.
