This is our largest and most widely distributed species, ranging from the 

 Saint Croix River, Maine, to Waco, Texas. It differs from any other in its large 

 size, the acute fore wings, and the well-marked tine lines on the fore wings ; the 

 two submarginal ones, instead of being ochreous, are usually black and con- 

 fused into a large conspicuous l)lack patch near the inner angle, while on the 

 hind wings there are often three well-marked, black, wavy lines; sometimes 

 th(^ lines are so lieavy on the fore wings as to inclose dark round patches. It 

 is a variable species, but always easily recognized. It is evidently double- 

 brooded in Texas, the moths appearing in May and again in August; but in 

 New England only in midsummer. 



Larva. — "Cater[)illar elongated, of a dark green, with the incisions and 

 a dorsal annular spot on each wing of a deep red; the under side dark roseate, 

 with a wliite stigmatal line on the posterior wings. It lives in the spring on 

 Rhexia lutea, and enters the ground toward the beginning of April. The 

 chrysalis is brown, and depressed on the Inick.'' — Guenee.

5 <f and 5 9. — Wliite, speckled with minute brown scales. Head 

 white on the vertex; front l^lack; palpi white, edged above with black scales. 

 Antennae of male with long coarse hairs. Tiiorax and abdomen white; wings 

 white, finely powdered with brown scales. Fore wings witli five yellowish- 

 brown lines, the basal one on the inner fourth of the wing much curved on 

 the median vein; the second is the broadest and most distinct, going obliquely 

 from the outer third of the costa to the middle of the inner edge; half-way 

 between this line and the outer edge is a wavy slender line, parallel to the
