The general ground color is ashy finely specked and mottled 

 Avith dusk}^, sometimes with a greenish or yellowish tinge. A 

 yellow median line margined with blackish, very distinct upon the 

 cervical shield, fairly evident upon the anterior segments, 

 especially the thoracic, but becoming obsolete posteriorly. A sim- 

 ilar subdorsal line, upon which rest the subdorsal triangular 

 black spots. These spots, limited to the anterior part of each seg- 

 ment, are wanting on the thoracic segments, (rarely faintly indi- 

 cated on the third,) and also on the two posterior segments, 

 although sometimes faintly apparent on the first of these. One or 

 two of the posterior pairs rarely connected transversely by their 

 posterior ends so as to form an irregular semicircle. The oblique 

 stigmatal dashes are confined to the same segments and the same 

 part of each segment as the subdorsal spots. These are some- 

 times margined by a dusky shade, thus forming a wavy stigmatal 

 band. The anal plate may bear a square brownish patch (trav- 

 ersed by the dorsal line) between the two yellow subdorsal lines 

 and beneath this a triangular black area, with the apex down- 

 ward. 



The head is yellow, much reticulate with brown, with two heavy 

 brown longitudinal bands upon each side of the middle, narrowing 

 forward and embracing between them the immaculate triangular 

 frontal area. Two much narrower and less definite longitudinal 

 brown lines upon each side of the head, with the upper ocelli 

 between them. Under side of head with a dusky shade inclosing 

 a pale area. Mouth parts pale, except the tips of the mandibles. 



Spiracular spots bordered below by yellow or flesh-colored 

 patches, sometimes obscured by dusky, occasionally extended to 

 form a substigmatal line. 



The species is seemingly single-brooded, and matures early, most 

 of our ]arv?e finishing their groAvth in April and early May.

This species seems to be two-brooded, as already surmised by 

 Co(iuillet and French, imagos of the first brood appearing in May 

 and early in June, and those of the second, late in July and in 

 August. For example, larva) wliich had hibernated, found abun- 

 dant in Urbana in April, 1887, commenced to pupate on tlio 28d of 

 that month, but still occurred May 0 in diminished numbers, of 

 various sizes, from half an inch in length to full grown. 



An imago evidently of this brood emerged May 10 from a pupa 

 obtained in Southern Illinois, and another, from the central part of 

 tint State, yielded the imago May 29. Ten larvjn taken from 

 (;abbage July 10, 1884, (Altered the eai'th for i>upation July '25, 

 and eraca'ged as adults August 15 to 19. Another imago of this
