 to show their actual relationship. 



On Corymb Ites Protractus. 



In the Bulletin for June, p. 77, a Corymhites from California 

 is mentioned and provisionally named Joutelii. Dr. E. C. Van 

 Dyke, of San Francisco, immediately suggested that it was a 

 light form of C. protractus Lee. The specimens were sent to 

 him and he writes : Your Corymhites is, as I was certain, nothing 

 more than a rufescent form of C. protractus. It cannot be a 

 species, nor even a subspecies. A number of our species of 

 Elateridee have that tendency to lose their pigment and become 

 a reddish or yellowish, passing into a condition called "rufinism" 

 and comperable to albinism and melanism, in fact intermediate. 

 It is very common among the Carabidag, among the subterranean, 

 littoral and arctic species. 



I am sending for comparison some typical protractus and 

 the reddish form taken with them. Also C. fraternus, a species 

 which is often confounded with it. The latter is found at higher 

 altitudes and is generally beaten from the coniferous trees, 

 whereas protractus is generally to be found in rather wet meadows. 



Calosoma Frigidum and C. Willcoxi at Wading River, L. I. 



By Wm. T. Davis, New Brighton, N. Y. 

 On May 29, 1913, it was observed that the trees about 

 Wading River, L. I., were being defoliated by a geometrid cater- 

 pillar since identified by Dr. Dyar as that of the "Fall Canker 

 Worm," Alsophila pometaria. The larvae were in great numbers 

 and their excrement fell in a ceaseless patter on the dry leaves 

 or the vegetation yet undestroyed. These caterpillars were 

 more abundant in some places than in others and to the south 

 of the railroad station, in the fiat country, none were observed. 

 They were particularly fond of hickories and oaks, but devoured 

 the foliage of all the trees and some of the lesser plants, excepting 

 the evergreens. They, however, wasted much of their food supply 

 for the ground was covered in places with bits of partly eaten 

 green leaves that constituted a considerable part of the foliage.
