Dorcaschema nigrum, Magdalis pandura, and M. barbita have all 
been reared from hickory twigs. Yomoderus constrictus has been 
reared from the stems of Heleniwm autumnale. 
Pholisora catullus has been reared from strawberry leaves in August. 
Palthis angulalis, Blastobasis glandulella, and the parasitic species 
Elachista proteteratis were all reared from seed cluster of sumae. 
Desmia funeralis with its parasite (Habrobracon gelechice), Pyralis 
costalis, Blastobasis glandulella, and Galasa rubidana have all been 
reared from masses of grape leaves collected in vineyards. 
Dichelia sulfureana and EHudemis botrana with the parasite Bracon 
mellitor were all reared from seeds of the garden sunflower. 
Lophoderus velutiana, Oxyptilus tenuidactylus, Exartema permun- 
dana, and a species of Glypta have all been reared from larvee feeding 
on the leaves of blackberry. 
Conchylis bunteana, together with the parasite Bracon iellitor, 
were reared from seed clusters of Vernonia noveboracensis. 
Grapholitha prunivora was reared from berries of a species of 
Cratzgus. ; 
Mellisopus latiferreana and Blastobasis glandulella were both reared 
from acorns. ; 
Tischeria malifoliella and Ornix geminatella, with the parasite 
Pimpla indagatrix, were all reared from leaves of the apple. 
A number of spraying experiments were carried out with the follow- 
ing results: Swift's arsenate of lead, 3 pounds to 50 gallons water, 
was applied to potato vines badly infested with Doryphora 10-lineata, 
and, though there was a heavy rainfall the night following the appli- 
eation, all small and medium-sized larvze were killed, and about half 
of those nearly or quite full grown. Later, the same experiment was 
tried, but again the application was followed by a heavy rain, despite 
which about 75 per cent of all larvee were killed. As against Ling 
lapponica, on willow, 3 pounds to 50 gallons water killed small and 
medium-sized larve, but did not seem to affect the older and larger 
larve. In another experiment, where 5 pounds of the arsenate of lead 
was used in 50 gallons of water, all larvee were killed and the foliage 
was not injured. 
Adler’s green arsenoid gave us the following results: For Lina lap- 
ponica, 1 pound to 100 gallons water killed small and medium-sized 
larve, but not the larger ones, with no injury to the willows upon 
which they were feeding. One pound to 50 gallons killed all larve, and 
also the foliage, though the latter put out anew later in the season. 
On rosebushes, and against Monostegia rose, 1 pound to 1450 gallons 
water was apparently effective and did not injure the foliage. 
Comparative experiments were carried out with green arsenoid and 
Paris green, with the following results: One pound to 100 gallons 
water, and 1 pound to 150 gallons water, with and without lime, did 
not appear to affect either the adult Doryphora or the foliage of the
