adjacent irregularly rugose; clypeus varying from yellowish to 

 brown, with evident vertical rugosities, this and the labrum 

 usually paler than adjacent parts. Antennae white at base, darker 

 towards tip. Cervical shield and anal plate brown to black, with 

 the usual three pale lines,— the lateral ones often becoming broad, 

 pale patches. 



Paeasites. 



The only evidences of parasitism of this species which came to 

 our notice were presented by two lots of larvse, one obtained at 

 the University June 12, among which, in the breeding ca^e, was 

 presently seen a mass of parasitic cocoons, which yielded, June 19, 

 a very small species of Meteorus seemingly undescribed. From a 

 single cutworm of the other lot, which had apparently shortened 

 up for pupation, several examples of the same parasite emerged 

 July 1, the larva being at this time dead upon the surface. 



The Greasy Cutworm.

, ■ (Plate IX., fig. 2.) 



This species is mentioned here only to record the fact that in 

 this latitude it was still actively at work in corn fields June 3 of 

 last year. Most of the specimens were, however, full grown, and 

 some shortening up for pupation, although others were scarcely 

 more than half grown. An examination of our breeding cage 

 showed pupae in the earth on the 17th June, and several imagos 

 had emerged by the 24th. Most of the larvse of this rearing, how- 

 ever, were parasitized by Tachina and Braconidae. 



The Variegated Cutworm. 



{Agroiis saucia, Huebn.) 



Although the relatively early development of this cutworm makes 

 it probable that it is a two-brooded species, I do not know that 

 examples of a second generation have been taken in any stage. 

 According to Eiley's notes, made at St. Louis, it seems to hiber- 

 nate most commonly as pupa or imago, its eggs having been re- 

 peatedly taken in April; but the occurrence of a full grown cut- 

 worm of this species in the grass near my office in January, 1888, 

 shows that it sometimes passes the winter m the larval stage. 



The caterpillars of the spring brood may feed in this latitude 

 until the first of June, sometimes pupating, however, by the mid- 

 dle of May, and sometimes not entering the earth until the mid- 

 dle of the following month. The imagos in our breeding cages 

 began to emerge June 14, 1888, but the moth did not become
