FAMILY LASIOCAMPAD.E. 237 



Attacus ceckofia. (Plate xliv, fig. 4.) 



Color dusk}' brown, reddish brown. The pattern of both pairs of wings is nearly alike. 



The base is reddish, bordered with white. The broad middle is dusky brown, in the 



centre of which are lunate spots, centrally white, but bordered Avith light brown. 



The middle of the wings is traversed by a narrow reddish white band, beyond which 



there is another broad dusky brown band ; in the outer and upper corner of which, 



there is a black velvety eyelike spot, marked by a narrow lunate line placed upon 



the inner edge : this outer border is bounded by a distinct black waving line, beyond 



which is a white border edged with brownish. The posterior wings, however, instead 



of the black waving line, have a row of black spots amounting to twelve or more, 



placed by a dusky brown waving belt : margin dusky white. Expansion of wing, 



six inches. 



This moth appears early in the summer, in sheltered warm places : it is out as earl}' as 



the middle of May. 



The caterpillar is of a fine light green color. The second and third rings bear two red 

 globular warts, around which arc numerous bristles : the seven succeeding rings bear oval 

 yellow warts ; and upon the eleventh ring, there is only one large wart. The sides are 

 ornamented with two rows of elongated blue warls, and the live first rings have an ad- 

 ditional row below. 



The young is yellow, and marked with rows of small warts upon its back. It fastens its 

 cocoon longitudinally to the side of a twig : the cocoon is usually three inches long, tapers 

 from the middle, and is constructed of double walls of silk separated by loose fibres of the 

 same, and has a resemblance to brown paper. 



The caterpillar is found upon several of our fruit-trees and shrubs, but I have never 

 been able to discover that its injuries were very serious. It is not very common : some 

 seasons, however, furnish more than others. 



Attacus prometheus. (Plate vi, figs. 1, 2, 3, 4.) 



Male, upper side : Color deep smoky brown ; the shoulders and basal parts deeper than 



the borders, succeeded by a central band of lighter color : this is terminated towards 



the border by a wavy line, beyond which is the clay-colored border, ornamented on 



the anterior wings by a wavy line, and on the posterior by black oblong spots between 



the line and middle band. Outer angle of the superior wings is ornamented also by 



a black eyelike :>pot, upon which there is a lunate line or crescent. 



Female, color brown, deepest upon the basal parts, which are marked by a curved whitish 



• line.- Each -wing bears spots, sharply lunate on the anterior wings, and bordered by 



black : besides which, the anterior wings are marked by an eyelike spot at their 



angles, within a bluish white crescent. The moth expands about four inches.
