their lower sides; there is a paler yellow spot between the bases 

 of the antennae and a deeper yellow transverse stripe at the 

 base of the head, both above and beneath. The thorax has a 

 yellow stripe on each side of its middle, a transverse one at its 

 base, which is slightly interrupted at the middle, and a short, 

 broader one on each side under the wings; its base on the under- 

 side is white. The abdomen commonly has two slender yellow 

 bands above, at the apex of the second and fourth segments, and 

 a white line on each side of the tuft of hairs at its tip. The 

 forward hips are yellow on their anterior face, the four others at 

 their tips. The shanks are yellow at their tips, the hind ones 

 have a yellow ring on their middle interrupted on the inner 

 side, the other four have a large yellow spot on their anterior 

 sides; their spines are white, their upper sides black, at least on 

 the basal half. The fore feet have a white ring at the apex of 

 each joint, and a broad white stripe upon the inner side; the 

 middle and hind feet have a slender white line on their inner 

 sides, which is often nearly obliterated, showing only a few white 

 scales at the apex of each joint. The wings are transparent and 

 glass like, with a slight tinge of smoky yellow; their veins, mar- 

 gins, and fringe is steel blue. The fore wings have a steel-blue 

 band beyond the middle upon their transverse anastomosing 

 veinlet, a slender yellow line upon their outer or anterior margin, 

 both above and below, and a similar line on the inner edge of 

 their inner margin; the hind wings also have a similar line on 

 the inner edge of their outer margin." Dr. Fitch also describes 

 seven varieties in this sex, which differ in the number and ar- 

 rangement of some of the markings. 



In describing the female moth Dr. Fitch says: "The female 

 differs from the male so much that it would not be supposed to 

 pertain to the same species. The abdomen is of a long oval form 

 instead of being slender and cjiindrical, and is twice as broad 

 across the middle as that of the male. This sex is of a glassy steel 

 blue color, with a purplish reflection in places, and blackish upon 

 the face, and upon the middle of the abdomen is a broad band 

 of a bright, glassy orange yellow color occupying the whole of the
