Even in the darkest forms the striaj shown in the (fig. 2 c, d) can as a rule be readily made out. The striated appearance, however, is usually weaker than in the larva of the conunon army worm, and the larger and more prominent black piliferous tubercles and the hairs proceeding from them with which the body of the fall army worm is marked will alone serve to distin- guish this insect from the army Avorm proper. In the latter the pil- iferous warts are minute and inconspicuous and the hairs so short that the body appears nearly smooth by contrast. The fall army worm is the smaller and slenderer and the entire bod3% including the head and cervical shield, is usually much darker. An illustration of the army worm is presented at figure 3 for com- parison. The head also presents good characters for the separation of these two larvtv. That of the fall army worm is smaller in pro- portion to the length of the body, nearly black, and with a white inverted Y-shaped mark in front not possessed by the army worm. These differences may he (easily recognized by comparison of the heads of the two species shown in figure -i at rr and h. TJw i)upi.—As shown in the illustration (fig. 1 r/), the pupa differs but litth' from that of the army worm, save in its smaller size. It is of the usual form and sliining mahogany-brown color of cutworm pupae, lighter when first transformed and darker when approaching maturity. The anal segment ends in a pair of minute spines. The spiracles and a considerable proportion of the integu- ment surrounding them are larger and much more prominent than in the [)upa' of th(> arni}^ worm, this character a})i)earing to be suffi- cient to distinguish between the two species at this stage. The length is about five-eighths of an inch (13-16 """).. Fig. 3.—Leuranin uni- piincta: larva—abrmt one-third enlarged (orig
