by larvee of Syrphus americanus and parasites, among which is Lys?- 
phiebus myz. Ashm. At several points the eggs of this aphis were 
very abundant, but few lice appeared and did but little damage. 
Myzus sp.¢—During the last week in April the stem mothers of an 
aphis, determined by Mr. Th. Pergande to be a species of Myzus, were 
found depositing young with A. mali. These stem mothers were 
large, globular, bluish-black, shghtly pruinose, and the young were of 
a light-brown color. This species curls the leaves much worse than 
the former, and has been found very common on apples throughout 
the State. On June 16 I found that they had been destroyed in one 
badly infested orchard mostly by parasites, among which were 
Lysiphtlebus cucurbitaphidis Ashm., and some undetermined species, 
and also by syrphid larve and Chilocorus bwulnerus. The adults of 
the next generation are of a brown color, marked with yellowish 
where the embryos show through the abdomens. The larve, pupe, 
and nearly molted adult apterous forms of the next generation are of 
a decided pinkish color, while the winged individuals are of a brown- 
ish-black color. The following generation is also partly composed of 
winged aphides. 
Aphis sp.—tLate in May an undetermined species of Ap/dzs spreads 
to the apples from wild-cherry trees and soon becomes thickly clustered 
upon the terminals. This species is bright yellowish and green, prom- 
inently marked with black. 
Lophoderus quadrifasciana Fern.—As the buds commenced to 
unfold in April, fine silk threads could be seen running here and there 
between the terminals. These were found to be made by small, yellow 
Tortricid larve, evidently just hatched from the eggs. Later these 
became a bright green color, and when full grown were about 10 mm. 
long. They pupated May 16 and emerged May 25 to June 2, the 
species proving to be Lophoderus quadrifasciana Kern, one not previ- 
ously noted as an apple insect. The larvee were quite common, and 
did more or less damage by webbing the leaves together. 
The larvee of Penthina chionesema Zell. have similar habits and have 
previously been noted as apple pests in Missouri by Miss Murttfeldt. 
The larve are so similar to the latter species that they were not dis- 
tinguished, though I find subsequently that they are considered larger. 
A larva of this species pupated May 14 and the moth emerged May 22. 
Larvee of Cacecia rosaceana Harr., are common, but not sufficiently 
so to do much injury. Moths emerged May 30. 
Cases of Jineola indiginella Zell. were found very common during 
the winter, but I did not observe much work of the larve in the 
spring. They pupated about May 15 and the moths emerged the first 
week in June. 
A small, reddish larva was observed to do considerable damage by | 
boring into the young buds, but I failed to rear it. Mr, Busck thinks
