ATTACUS. 223 



a central subvitreous streak, containing a yellow circle, and toward 

 the base of the wing a slender blue crescent. A whitish band 

 crosses the middle of the nervules, with a faint wavy one between 

 it and the hind margin. In the apical interspace is a black spot, 

 with a crimson streak to the tip of the wing. The marginal por- 

 tion of the wing is whitish and is tinged in the terminal edge with 

 pale yellowish-brown. Hind wings similar in color and ornament- 

 ation to the fore wings, the ocelli being somewhat smaller. On 

 the under surface, which is similar in hue to the upper, the faint 

 wavy bands of the fore and hind wings are very distinct.

ATTACUS Linn. 



The Attaci are distinguished from the Satumians by their su- 

 perior size — the wide, strongly pectinated antennae in hoth sexes; 

 the horizontal and widely extended wings, which are marked with 

 vitreous, diaphanous spots, and by the tubercles on the backs of the 

 larvffi. ,

Antennas brown and broadly pectinated. Body fulvous. Thorax 

 very hairy, with a white band before. Abdomen annulated with 

 alternate white and dark brown, the latter edged behind with black ; 

 primaries falcate at their extremity. They are brown and covered 

 with a white dust; a fulvous spot at the base, bordered with whit- 

 ish. On the disk, a semi-transparent reniform spot, bordered with 

 black, with a white centre. A fulvous band crowned with white 

 crosses both wings ; a sinuous whitish band on a grayish ground 

 crosses the posterior edge; towards the inferior angle there are 

 two or three irregular round black spots in a series ; near the up- 

 per angle there is an ocellated black spot, nearly surrounded with 

 green ; between this and another oblong black spot on the tip, 

 there is a mark similar to an inverted W. 



Secondaries similar, excepting the lower edge, which has a nar- 

 row brown band ; above it a series of spots of the same color, on 

 a grayish ground, which is surmounted with a broad band of brown. 

 The discoidal spot is larger and the transverse band broader.
