cognatarta Guen., Lycia 
The larva of Lycia cognataria is green and is 44 centimeters long. It 
has two pairs of prolegs. On its head are blunt horns, and it bears a 
prominent red tubercle on the next to the last segment. It feeds on 
Crataegus punctata and C. pruinosa foliage in July. It is not a common 
species. 
magnarius Guen., Hnnomos 
A moth of Ennomos magnarius emerged from a brown silken cocoon on 
a twig of Crataegus pruinosa on September 30. Eggs were found on 
a C. punctata twig on November 12. The brownish larvae, 5 centimeters 
long, were found occasionally in May and June. 
pometeria Peck, Alsophila (Fall cankerworm) 
The small greenish or brownish larvae of Alsophila pometeria are fairly 
common on native hawthorns in May. 
subsignarius Hiib., Ennomos 
The white moths of Ennomos subsignarius emerged on July 6 and July 
18 from pale yellowish pupae which were found tied with silk between 
the leaves of Crataegus punctata. A few of the brown and red larvae were 
found feeding on the foliage of native hawthorns in May. 
tiliaria Harris, Erranis (Lime-tree spanworm) 
The yellow-and-black-striped larvae of Erranis tiliaria are common 
on native hawthorn foliage in May and June.

The larvae of Paleacrita vernata are common on foliage of native and 
European hawthorns in May and early June. 
Sesiidae (Aegeriidae) 
scitula Harris, Sesia 
A single Crataegus punctata tree about eight years old and 5 feet high 
was killed by the larvae of Sesza scztula. The trunk was entirely girdled 
by four larvae which tunneled beneath the bark two inches above the 
soil. The sapwood was only slightly indented by their burrows around it. 
They pupated during June in silken cocoons covered with frass within 
the burrows, and the moths emerged from July 18 to July 24. In emerg-
