the pan a strip of cloth reaching the whole length and pour- 
ing upon it at least a pint of kerosene. The canvas at the 
back of the pan should also be kept wet with the oil. This 
plan of using the hopperdozers is as used by Dr. Lugger 
who has had a large amount of experience with them in 
Minnesota. Every grasshopper that comes in contact with 
these cloths and gets the oil upon any portion of itself will 
soon die. As the oil evaporates more must be added. 
In orchards, vineyards and gardens where the pans can- 
not be used, poisoned baits made by mixing one pound of 
Paris green with six to ten pounds of bran, with just water 
enough to moisten the whole, may be prepared and scat- 
tered about in small quantities where the hoppers are thick- 
est. Many will eat the poisoned bran and die. Paris green 
or London purple may also be sprayed on the food plants 
of the grasshoppers where it is safe to use it. Care must 
also be exercised in the use of poisoned bran that chickens 
and other domestic animals may not be poisoned. 
THE MEDITERRANEAN FLOUR-MOTH. {Epliestia kulinieUa 
Zell.) 
This insect has attracted attention in this country and 
in Europe almost exclusively as a pest in flouring-mills. My 
attention was first called to the insect in Colorado on Sep- 
tember 14th, 1893, when I received some honey comb from 
Mr. R. C. Aikin of Loveland, which was very badly infested 
with the larvae and webs of this insect. The moths were 
also appearing at the time. The moth is gray in color with 
narrow wings and spans about three-fourths of an inch and 
is very well represented, at Phg. 48. Eig. 49 shows the ap- 
pearance of the webs on a frame of honey comb. 
'' Fi^. 48.— Mediterranean Flour-Moth: a, moth with wings spread; b, moth 
with wings closed; c, larva; d, chrysalis; e, two segments of the larva greatly en- 
larged. All soniewhat enlarged. (Riley & Howard, Insect Life, Vol. II, U. S.
