The distribution there accorded is "Nova Scotia to Texas, east of the

 N. J., "common everywhere", (Smith); Marshall Hall, Cabin John, Md. ; Wash- 

 ington, D. C; Virginia; St. Louis, Kirkwood, Mo.; Dayton, Ohio (Pilate); Hearne, 

 Dallas, and elsewhere in Texas; Canton, Kirkwood, Miss. ; Macon, Ga. ; Alabama; 

 Woodstock, 111.; Volga, S. Dak., and St. Anthony Park, Minn. (Lugger). Also

About the city of Washington this moth is one of our latest as well 

 as earliest species, individuals occurring commonly in the writer's 

 experience about the Department buildings throughout the month of 

 November, as late as the first week of December, and as early as March 

 10. An individual was observed flying on the last-mentioned date in 

 a temperature of 51° F., which is about the lowest temperature in 

 which any save exceptional species of insects are active. 



This insect is a near relative of the hop- vine snout moth, Hypena 

 humuli Harr. , with which species it was, in fact, confused at an 

 earlier date. 



The green clover worm has not attracted much attention on account 

 of its injuries, but good accounts of it have been given by Prof. J. H. 

 Comstock in the Annual Report of this Department for 1879 (p. 252), 

 and in the Canadian Entomologist for July, 1881 (Vol. XIII, pp. 

 137-138), the latter paper by Mr. Coquillett, of this Division. 



THE EARLIER STAGES OF THE INSECT. 



The egg. — Owing to an oversight, the eggs obtained hatched before 

 a detailed description could be made. . Dorsal and side views of the 

 egg, however, were drawn, and are illustrated herewith (fig. 26, c, d), 

 and from these a. general idea of the egg as it looks under the micro- 

 scope may be had. From memory the writer believes that the eggs 

 were light gray in color and at least tinged with iridescence. Follow- 

 ing are Mr. Coquillett's descriptions of the egg and of the first stage 

 of the larva: 



Globular, slightly flattened above, more decidedly so below; lower half smooth; 

 upper half deeply grooved, the interspaces rounded and marked with fine transverse 

 impressed lines; whitish, the upper half sometimes dotted with dark brown; trans- 

 verse diameter, nearly 0.5 mm . 



Measurements showed an average diameter of 0.5 mra and a height of 



0.35 mm . 



THE LARVA. 



First stage. — "Body green; a dark-colored dorsal line, edged each 

 side with a whitish line; a white subdorsal and stigmatal line; pilifer- 

 ous spots green, each bearing a short black hair; venter green; head 

 polished green ; body provided with only 14 legs. "
