Noctuidae A common species in the Atlantic States, the fall of the year in western Pennsylvania. It is abundant in Genus HELIOPHILA Hiibner A large genus well represented in both the eastern and the western hemispheres. Thirty-six species are credited to our fauna. Of these we give figures of eight, selecting the commoner and a few of the rarer forms. (i) Heliophila unipuncta Haworth, Plate XXIV, Fig. 40, $ . (The Army Worm.) Syn. extranea Guen6e. This species, the larva of which is known as the "Northern Army Worm," or simply as the "Army Worm," is found from the Atlantic to the Rocky Mountains, and from Canada to Texas and southward at suitable elevations upon the higher plateaus of northern Mexico. It appears occasionally in vast numbers, and is regarded by the farmer and the horticulturist as one of those pests against the ravages of which they must direct a great deal of energy. The first appearance of these insects in great numbers is recorded as having occurred in New Hampshire and Massachusetts in the year 1743. In the year 1770 they devastated the fertile fields of the valley of the Con- necticut. They devoured the grasses and cereals, but neglected the pumpkins and potatoes. The chronicler of this invasion says: "Had it not been for pumpkins, which were exceedingly abundant, and potatoes, the people would have greatly suffered for food. As it was, great privation was felt on account of the loss of grass and ; Suc- cessive attacks of the insect have been made since then upon the crops in various parts of the country. The year 1861 is memorable as having been marked by their ravages, which were particularly noticeable in the State of Missouri and in southern Illinois. An excellent account of this invasion has been published. Fig. 110.—Larva of H. unipuncta. (After Riley.) Fig. III.—Pupa of H. unipunct
