ment, it is marked with dark brown, as if covered witk 

 a lace veil, a longitudinal stripe of the same color in front, 

 on each side a smaller one. Body dull greenish, lighter on 

 the belly, an almost continuous white line on the back, 

 with a wide dark one on each side, fading off from it, 

 till it reaches another black stripe, then another white one 

 tinged with reddish brown, bordered, with black, a fine 

 white one, another black one, in the lower border of 

 which are the very black stigmatae, next a fine white one, 

 another reddish brown, lighter than the others, another fine 

 white one, and last the belly, greenish brown, variegated 

 with fine brown spots ; ten prop legs, naked, some much 

 lighter than others. 



When they have arrived at this state, they leave off feed- 

 ing, and go into the ground, where they cement together 

 the earth around their skins, and turn into pupa} of a ma- 

 hogany color. The chrysalis or pupa remains quiet until it 

 bursts its shell and comes forth a moth ; in about half an 

 hour it has its wings expanded and ready for flight ; it then 

 flies around, pairs, and deposits its eggs, not living proba- 

 bly over three weeks in this its final state. 



The fore wings and front part of the body of the moth, 

 are reddish brown ; on each fore-wing, a little beyond the 

 middle, there is a bright white spot, from this, nearly to the 

 body, a black line runs along the median nervure, half 

 way between this spot and the outer margin of the wing, 

 is a row of black dots, one to each nervure, from the front 

 branch of the median nervure a black line runs obliquely 

 to the apex ; there is another row of black dots beginning 

 at this line and extending to the inner angle, a dot alterna- 

 ting with each nervure. The hind wings are pearly grey, 

 lighter towards the body, particularly underneath. The 

 hind body is blueish grey. The legs, underside of the body, 

 and collar -like band above the head, are lighter ; the anten- 

 nae are also lighter at the base ; the tongue is well devel- 

 oped. Expands 1.7 inches. A very accurate and scientific 

 description of the insect will be found in the sixth annual 

 report of the Secretary of the Maine Board of Agriculture, 

 1861, on the 130th page, by A. S. Packard Jr.
