by June 18. The moth is attracted by the electric light, and oc- 

 curred in large numbers August 17, 1886, and again on the 19th,. 

 20th, 21st, and 23d (at this last date numerous), and continuously 

 thereafter until September 23, after which time it was not col- 

 lected. The following spring it commenced to appear at the elec- 

 tric light on the 19th May, and by the 23d was very abundant, 

 continuing extremely common until June 3. The 6th and 7th 

 June several moths were taken, and additional examples later, — 

 from three to eight at a time, until the 18tli of that month, after 

 which only a siugle specimen occurred — captured July 14. It is 

 thus clearly a two-brooded species, with a short spring interval of 

 mischievous activity, its damage ceasing practically by the first of 

 May. 



DESCRIPTION OF LARVA. 



A pale, much-striped cutworm, marked by an especially distinct 

 lateral black stripe, and unusually stout, conspicuous black or 

 yellowish bristles. General color yellowish gray, darkened by 

 minute granulations. A pale dusky stigmatal band, bordered with 

 darker, and above this (with a fine white line intervening) a 

 prominent darker band less distinct on the thorax; then, next 

 above, a brownish or reddish subdorsal band, bordered with white, 

 most conspicuous on the thoracic segments. Dorsal space gray, 

 with a broad moniliform dusky shade contained between the inner 

 piliferous tubercles, this travwsed by a rather broad continuous 

 median white line. Substigmatal band mottled cream color, paler, 

 than stigmatal, and lighter also than the dusky venter. Prolegs 

 with a brown patch outside of bases, and jointed legs similarly 

 colored. Cervical shield not well marked. 



Head opaque, with black granulations, darker than usual, very 

 hairy, with the usual curved frontal black bands and darker retic- 

 ulations on the sides. Antennal joints one, two, and three, white, 

 black, and brown, respectively. 



This larva attains a length of one inch. 



Described from ten specimens.

This is clearly a single-brooded species of rather long-continued 

 larval life. The eggs are laid, and probably also liatched, in 

 autumn, the species wintering in moadcnvs and i)astures as a young 

 larva. Exam|)l(\s obtained May 29, in Pooria county, where they 

 were reported as very destructive to corn, were still feeding July 

 7, l)ut ])upated Ijetween July 15 and August 3. Tiie iniagos had
