scarlet. There is besides, a broad longitudinal stripe of the same 

 color, furcate on the outer half of the wing. Fringes lead color. In 

 many specimens the scarlet of the wings is paler, and the costa and 

 basal half of the central stripe are strongly yellowish. 



Secondaries scarlet, with a broad outer plumbeous band. In those 

 specimens which show yellow tints on the primaries the secondaries 

 are much paler, and the outer band is reduced to half its width, and 

 strongly sinuated on its inner edge. Fringes slate color, concolorous 

 with the outer band.

Larva. — Of the larva Dr. Harris says, (Ins. Inj, Veg. , p. 342, Ed. 

 1862) : "The caterpillar lives upon lichens, and maybe found under 

 loose stones in the fields in early spring. It is dusky, and thinly cov- 

 ered with stiff, sharp, and barbed black bristles, which grow singly 

 from small warts. Early in May it makes its cocoon, which is very 

 thin and silky ; and twenty days after is transformed to a moth."
