ing species of the genus Chenopodium, although it fed 
indiscriminately upon the native weeds here. Among 
cultivated plants, it attacked all vegetables, except squash, 
egg plant and Irish potatoes. An acre of tobacco was 
untouched, but field and sweet corn, wheat, oats, alfalfa, 
clover and strawberry plants were devastated. On alfalfa, 
it fed to its tops, and in some cases defoliated young plum 
trees four feet from the ground. The first larvae were 
noticed May 29 (then quite small); trom this date to July 
15, larvae of all sizes were working together, and were in¬ 
jurious as late as July 4. The cocoons were readily found 
in the rubbish at the collar of the plants attacked. The 
larvae appear to be gregarious, as they fed in numbers on 
the same plant, over which they spun an intricate web, 
along which they traveled with alacrity when disturbed. 
Remedies —We made our first application of Paris 
green June 1st, using one pound of the poison to one 
hundred gallons of water, which proved to be very effect¬ 
ive and not injurious to the plant, but we had to make a 
second application on the 20th of June, and finally on 
July 3rd, after which, garden plants that had been 
treated were not further troubled, although mature larvae 
were to be obtained for some days afterwards on fields of 
alfalfa. We used a hand machine to spray a six-acre gar¬ 
den. On a large scale, and by using the barrel or tank 
and pump and a good cyclone nozzle, much quicker and 
cheaper work could be accomplished. Although we have 
had a formidable visitation of this insect, we do not con¬ 
sider it at all difficult for the gardener to control. The 
farmer, because of his broad acres and general lack of 
preparation to meet such contingencies, is apt to suffer 
most.

This weevil continues to damage field and garden peas 
considerably. Our seeds of all the varieties grown this
