436 REVISION OF FAMILY SATURNIID^. 



The variety aurosea, as has been remarked, differs in the deeper more 

 reddish shade of the ground color. The venation of primaries is as in 

 io and the others of the genus. The secondaries have 2, 3, and 4 from 

 the median at about equal distances; the cell is closed by a slender 

 vein, drawn inward at center, and forming thus two waves ; 5 aud 6 

 are from the same point at the upper end of the cell, and 7 is from the 

 subcostal near the end of the cell. The genitalia are peculiar, the supra- 

 anal plate forked, the forks pointed and curved outwardly, and covering 

 another pointed corneous plate. The side piece is peculiar in shape and 

 difficult to describe in words. The figure must serve to make it clear. 



The insect has been raised by Mr. J. Doll. I have seen the larva in 

 Mr. Neumoegen's collection. So far as I know it has not yet been 

 described.

Primaries are even, soft, deep smoky gray, a distinct somewhat 

 curved white line crossing obliquely from the middle of the inner mar- 

 gin to the apex. At the end of the cell is a rather large black ring 

 with a more or less indistinct white center. At the extreme base of 

 the wing is a narrow white line. Thorax and head cpncolorous with 

 primaries. Secondaries pink at base, and there densely clothed with 

 long fine hair. The outer margin is pale gray, sharply limited inwardly 

 by a black line. A darker gray shade equidistant from this line aud 

 the margin. Disc of wing bright yellow, within which is a large black 

 ocellus with a linear white pupil, marked with pale blue scales each 

 side. Abdomen deep carmine red, the tip and under side mouse gray. 

 Beneath, pale mouse gray, primaries with a large black discal spot with 

 white center, secondaries with ocellus faintly reproduced. Expands 

 2.25-3 inches. Hah., Kew Mexico. 



The venation of primaries in this species is in all essentials like that 

 of io. The secondaries differ from all the other species in that the cross 

 vein closing the cell runs obliquely upward, making the cell pointed 

 with V. 4 from the point. 



This species is still very rare, and I have been unable to obtain speci- 

 mens of which I could examine the genitalia as closely as I desired. 

 The shape of the side piece I could make out, aud that I figure at pi. xiv, 

 f. 10; but the supra-anal plate I could not examine. This is perhaps the 

 handsomest and most distinctly marked of all the species, and by its 

 dark color and the oblique white band is not likely to be wrongly iden- 

 tified. Professor Snow has bred this species, but I have seen no descrip- 

 tion as yet of the larva.

 not more than half the length of the lower ; the female antenuai simple.
