Geometridae 



cognataria Guen., Lycia 



The larva of Lycia cognataria is green and is 4^ 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., Ennomos 



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 canker worm) 



The small greenish or brownish larvae of Alsophila pometeria are fairly 

 common on native hawthorns in May. 



subsignarius Hub., 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. 



titea Cram., Phigalia 



Two larvae of Phigalia titea were found feeding on Crataegus punctata 

 leaves on June 2 and June 5. 



vernata Peck, Paleacrita (Spring cankerworm) 



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 Sesia scitula. 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-
