Report of the State Entomologist. 139 



Fletcher has rej^orted two captures of it at Ottawa (latitude 45°), and 

 Mr. Saunders has cited several other instances of its capture in 

 Canada during the past few years {Canadian Entomologist, xii, 1880, 

 p. 211). 



We have no knowledge of the early stages of this insect beyond 

 some brief notes upon its eggs and the first stage of the caterpillar, 

 made at Nassau, New Providence, by Mrs. Blake, and recorded by Mr. 

 H. T. Fernald, in Entomologica Americana, iv, 1888, p. 36. 



Zerexe CATEX.4.RIA Cramer. — Numbers of this moth were taken by 

 'Mr. Erastus Corning, Jr., on the evening of September 21st, 1887, 

 from the windows of a drug-store, fronting Capitol Park, to which 

 they had evidently been attracted by the lights within. Fifty or more 

 examples, it is thought, could have been taken at the time. 



It may be readily recognized by its snow-white and unusually thin 

 wings, crossed near their middle by 

 two black, toothed lines — sometimes 

 broken into lines of dots upon the 

 nervules. The head, and front of the 

 wing-covers are ochreous-yellow. The 

 hinder margin of the wings is dotted 

 with black at the end of the veins, fk;. 55. ^z^ene catenaeia. (After

plumose antennae; in the female they are thread-like. 



For an account of a remarkable flight of this moth, in October, 

 1880, in Lackawaxen, Pa., which, from its immense numbers, appear- 

 ing in some places as a dense snow-storm, alarmed farmers who fool- 

 ishly feared that it was the precursor of an army -worm attack: — see 

 Report of the Commissioner of Agriculture, for 1880, p. 274. 



Anisopteryx pometaria Harris. — Caterpillars of this species, the 

 fall canker-worm, which is of rare occurrence compared with the 

 spring canker-worm, A. vernata Peck, were received from Moriches, 

 Suffolk county, N. Y., on June eighth, from Mr. Augustus Floyd. 

 They had made attack upon his apple trees and were rapidly consum- 

 ing the foliage. Doubtless some of the attacks ascribed to A. vernata, 

 in reality belong to this species, discrimination between the two not 

 being made by the observer. 



Through an error discovered too late for its correction, figures 

 illustrating A. vernata were received from the Department of 

 Agriculture, instead of those of A. pometaria, desired. They will, 

 however, serve to show the form that more commonly comes under 

 observation. In Figure 56, a, is the mature larva in its natural size: h
