42 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



ited upon the hop-vine as it begins to climb. It hatches in a few days 

 and the slender, black-spotted, greenish larva produced, burrows into 

 the vine just below the tip, soon causing the vine to cease climbing, 

 point downward, and almost to stop growing. When the larva has 

 attained a length of about half an inch, it emerges from the tip, drops 

 to the ground, and enters the stem at the surface of the vine, where it 

 feeds upward for a time. When it has grown to about an inch in length, 

 it changes its direction and burrows downward to the base of the vine, 

 at its junction with the old stock, and, eating its way out, completes its 

 growth as a subterranean worker. The journey from the stem to the 

 ground is made in the beginning of June, and before the 20th of the 

 month. Here it eats a small hole into the side of the stem just below 

 the surface and immediately above the old root. The hole is gradually 

 enlarged until the vine is barely attached to the root, or, as sometimes, 

 entirely severed from it. 



By the middle or the 20th of July, the larva (two inches in length) 

 has matured, when it transforms to the pupa state in a rude cell, close 

 to the roots of the plant. 



Mr. Smith states that the insect hibernates as a pupa, although " a few 

 specimens of the moth appear in the autumn, but the majority appear in 

 the spring, from the beginning to the end of May or later, according to 

 the season. Whether the former hibernate or whether they perish, I 

 have not been able to ascertain, though the latter seems the more 

 likely." 



My own observations, and such records of the moth as are accessible 

 to me, indicate its late summer appearance only, and consequently, by 

 inference, hibernation in that stage. My collections of it have been 

 made only between August 25th and September 6th; and the examples 

 in the collection of Mr. W. W. Hill, of Albany, bear the date of 

 August 15 and 26. It is recorded as having been taken by Mr. O. S. 

 Westcott, at Maywood, III, on August 26, September 3, 4, 10, 11, 22, 23 

 {Canadian Entomologist, viii, 1876, p. 15); by Mr. Roland Thaxter, at 

 Newton, Mass., in August {Psyche, ii, 1877, p. 36); and by Mr. C. E. 

 Worthington, at Chicago, 111., also in August {Canadian Entomologist, 

 xi, 1879, p. 69). The species does not appear in the published lists of 

 collections of Noctitidce of Messrs. Norman (at St. Catharine's and Orilla, 

 Canada), Hill (in the Adirondack Region of New York), Devereaux 

 (at Clyde in Western New York), Pilate (at Dayton, O.), and Prof. Snow 

 (of Eastern Kansas).
