FAMILY LASIOCAMPAD.E. 237 



Attacus ckcropia. ( Plate xliv, fig. t.) 



Color dusky biKWii, ie<Jili>li l>ro\vn. The pattern of hotli jiaiis of wings is nearly alike. 



The base is reililish, bordered with white. The i)road middle is dusky brown, in the 



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



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



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



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



the inner edge : this outer border is boimded I>y a distinct black waving line, beyond 



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



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



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



six iuclies. 



This moth ajipcars caily in the summer, in slieltered warm places : it is cut as early as 



the middle of May. 



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

 globuliir warts, aroiuid which are numerous bristles : the seven succeeding rings bear oval 

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

 ornamented with two rows of elongated blue wai'ts, and the five 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. 



Attacis piioMETHEus. (Plate vi, figs. 1, 2, 3, 4 )

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

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

 a black eyelike r-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
