To destroy a first brood in bearing fields, it will of course be 
necessary to use means which will not injure the fruit. The only 
insecticide which it will be proper to employ under these circum- 
stances is pyrethrum, and it is not certain that this would be effei 
tive as no experiments have been made upon this precise species. 
I have found it sufficient, however, for the destruction of the rose-slu ? 
(Selandria rom, Harris), a species closely allied to that under con¬ 
sideration. Further than this, I know of no feasible remedy, excepl 
hand picking, or capture with an insect net As the .larvae an 
easily startled, and drop to the ground when alarmed it is not im 
possible that they might be . swept from the vines with a net, and 
destroyed by emptying them into a pan or bucket containing a filn, 
of kerosene upon water. 
If the fruit-grower should be watchful enough to detect the nie 
in earlv spriim, as they frequent the vines for the purpose of deposit) 
ing thL eggs it is quite likely that lie might protect his fields b| 
usrng the insect net to capture them, in the cool of the day, whej 
they are sluggish, and slow to take flight. 
To destroy the second brood, where it occurs, or the first in youn 
fields not yet in bearing, or where the crop itself has already bee 
ruined Paris green or London purple will be found efficient, accon 
ing to the observations of Prof. Osborn reported in the Transactor 
of the Iowa State Horticultural Society for 1882. Hellebore wou] 
doubtless prove equally effective, as this is the general specific f( 
all saw-fly larvae. It is further quite likely that mowing and bun 
ino- the fields, as for the leaf-roller, would likewise serve for tl 
extermination of the second brood of this species. 
The Eose Slug, (Selandria rosae, Harris.) 
Order Hymenoptera. Family Tenthredinimi. 
This species is mentioned here only to call attention to the h 
that it has been reported by Mr. Townend Glover, formeily Um . 
States Entomologist, to attack the strawberry when its ordm£| 
food fails. 
The Brown Strawberry Span-Worm. 
(■Cymatophora pampinaria, Pack.) 
Order Lepidoptera. Family PhAL iENiDiE. 
This species was found by us in midsummer so frequently, fill 
ing upon the leaves of the strawberry in Southern Illinois, as 
make it worthy of brief mention here. It is a slender loop

caterpillar, brown in general color, about an inch in fiir 
and gives origin to a gray moth which expands from three-rouu
