628 APPENDIX. 



Nearly in the centre of the wing is a milk-white dot placed 

 upon the mid-vein. This dot is surrounded more or less by 

 a dusky cloud, and this duskiness is frequently extended for- 

 ward upon the mid-vein to its base, forming a faint darker 

 streak along the middle of the wing. Contiguous to this 

 dot on its outer side may be discerned a roundish spot of a 

 slightly paler yellow color than the ground, and a very short 

 distance forward of this is a similar spot, but smaller, both 

 these spots often showing a more tarnished centre. On the 

 hind part of the wing the veins are marked by slender, whit- 

 ish lines, and between their tips on the hind edge of the 

 wing is a row of minute black dots. The hind wings are 

 smoky brown, with a purplish gloss, and are nearly trans- 

 parent, with the veins blackish. The fringe of both pairs 

 of wings is pale yellowish, with a dusky band on the middle. 

 On the under side, the wings are much more glossy and 

 paler, opalescent whitish inwardly, and smoky gray toward 

 their outer and hind sides, where they are also freckled 

 with blackish atoms. The smoky color on the hind wings 

 has on its anterior edge a row of short blackish lines, one 

 on each of the veins, and in a line with them on the fore 

 wings is a faint dusky band, becoming more distinct toward 

 its outer end, or sometimes only represented by a dusky dot 

 on the outer margin forward of the tips. The veins are 

 whitish, and also the hind edge, on which is a row of black 

 dots placed between the tips of the veins. The hind wings 

 have also a blackish crescent-shaped spot a little forward of 

 their centre. The abdomen or hind body is smoky gray above, 

 and on its under side ash-gray, freckled with black scales, 

 and usually showing a row of black dots along each side.'"* 

 The Larva, or " army-worm," varies considerably in 

 color and size, owing to age and locality, but its charac- 

 teristic markings are so constant, as to make it readily 

 distinguished. As it appeared in New Hampshire and 

 Massachusetts, it varied in length from less than one 

 inch to one and three quarters, was of a dark gray, w T ith 

 three narrow yellowish stripes above, and a broader one of 

 the same color or slightly darker on each side, thinly clothed 

 with short hairs, which were longer and somewhat thicker 

 on and about the head, the latter of a polished honey-yellow, 

 with a net-work of fine dark brown lines, and a black line 

 on the front like the letter V reversed. The following
