of middlings and Paris green. In case corn is so injured by it as to 

 require replanting, this may be safely done any time after the first of 

 June, or possibly as early as the last week in May. To be sure that a 

 grass sod shall be virtually free from the eggs, this should be plowed as 

 early as the first week in September. 



H ADEN A LIGNICOLOR Guen. 



This cutworm closely resmebles the glassy cutworm, but has never 

 been fully described in the caterpillar stage. We have not found it com- 

 mon in Illinois, but have collected the moths during June, July, and 

 August. Gillette reports that the moths are very common in Iowa, 

 They are found generally in the northern part of the United States east 

 of the Rocky Mountains, and have been reported from Arizona. 



A cutworm of this species whicli was found by Lintner preparing for 

 pupation May 18, completed its transformations and came out as a 

 moth on the 29th of June. Females dissected by Gillette July 13 were 

 well filled with eggs. 



These facts indicate a comparatively early close of active life as a 

 cutworm, and a comparatively early appearance of the adult moth. 



The W-marked Cutworm. 

 Noctua dandestina Harr. 



This caterpillar (Fig. 14) is marked with four longitudinal rows of dark 

 spots and some dark and pale longitudinal lines. The spots of the outer 

 row on each side are oblique, and sometimes 

 unite to form a continuous line; those on the 

 inner row are more or less triangular fmost 

 evidently so on the hinder segments), and occa- 

 sionally have the shape of the lettr W. 



This is a very wide-spread species and a 

 general feeder, but is ordinarily much more 

 abundant in the East than in the north-central 

 states. It is not found in the South. Dr. Lint- 

 ner regards it as the most injurious corn cut- 

 worm in New York, where it is said to be com- 

 mon also on grass and grain, and to feed on 

 buckwheat and clover. It is fond of garden 

 vegetables, and feeds on lettuce, cabbage, celer^^ 

 pumpkins, and beans. It is a well-known climb- 

 ing cutworm, ascendingt tees and shrubs to eat 

 the buds and leaves, particularly those of the 

 apple, box-elder, soft maple, currant, and 

 gooseberry. Plantain is mentioned as one of its wild food-plants
