INSECTS AND INSECTICIDES.

May, laying its eggs beneath the skin of the raspberry 
leaf. The larva is the color of the leaf, but its work 
reveals its presence. It may be destroyed by hellebore, 
an ounce to a pailful of water. 
The cabbage and turnip aphis are always destructive 
in a dry climate. The kerosene emulsion will kill them 
whenever they can be reached. It is not difficult to 
counteract them, if the work is begun in time. The work 
of these aphidae may, however, be lessened by planting 
those plants in rich ground only. If they once become 
stunted, then this insect will work their destruction. 
The blister beetles ( Lytta cinera and Lytta attrata) we 
received from the Arkansas Valley this season. They 
feed voraciously on the potato, beans and other garden 
vegetables. We are annually more or less troubled with 
the striped flea beetle ( Ilcdtica striolata). These beetles 
are very small, but active, and are present usually in 
great numbers on cabbage, radish and turnips, while the 
plants are still small. We made one application of Paris 
green on June 2nd, and succeeded in saving the plants. 
Grasshoppers were very injurious in various portions 
of the State, owing to lack of rain on the range, render¬ 
ing the latter destitute of green herbage. 
The corn worm ( Hehothis armigera), is annually injur¬ 
ious to corn in the ear wherever the plant is grown in 
the State. The moths were abundant in the month of 
October in Southern Colorado this year. 
The bee killer ( Trupcmeaapivora). This fly is numerous 
enough on the plains and in the mountains. It is said to 
prey especially on the honey bee. We have witnessed it 
the past season at high elevations in the mountains 
attacking and killing dragon flies ( Libellulidce ). It seizes 
these powferful hies on the wing, and, after a severe 
struggle, both fall suddenly and with force to the ground, 
where both are readily captured. 
The three-lined leaf beetle ( Lema trilineata ) was noticed 
in numbers on the tomato and potato. The larva is read-
