 two spots.

 of the veins ; of hind wings white, except those of the 

 tail on the inner margin, which are black.

 glaucous color all over their surface except the tail, the 

 anal two-thirds of the outer margin, and two bands 

 through the wings, which are olive-brown, the tail almost

 side are two black patches. The whole surface is 

 sprinkled over with a few whitish and yellowish scales.

 dark dorsal line, a bright yellow subdorsal band, which 

 is dilated on the twelfth segment, and a pale green line 

 along the base of the body. The dorsal space, between 

 the bands, is gray dotted with black and yellowish ar- 

 ranged in transverse lines. The sides are gray, with the 

 upper half dotted with black. Collar lustrous black ; 

 anal plate yellow, greenish in the middle. Under side 

 pale green, legs black, prolegs yellow. Head large,
