ing obliquely forward and downward from the lower front part of the head, 

 of a darker brown with longer and less dense hairs of a red color along 

 their underside and around the mouth. Coiled up between them is the 

 spiral tongue, of a white color, and only equaling them in length when 

 extended. The antennre reach a third of the length of the wings. They 

 resemble slender, tapering threads, white, their tips brown, their basal 

 joint red, and a brown stripe along their underside. In the males they are 

 pectinated, each joint sending ofl' two short brown branches. The thorax 

 is glol)Ular and brown, with a broad white band in front, occupying the 

 base of the collar and extending backward across the shoulders and uniting 

 •with the white stripe or spot upon the middle of the base of the wings. 

 The collar is edged all around with crimson red, forming a slender margin 

 along the lower edge of the white band and on each side crossing this band 

 and forming a narrow arched band above it. The base of the thorax is 

 also slenderly margined with red, which color widens on each side into a 

 small spot. The sides of the thorax arc pale brown, with a pencil of red 

 hairs in the axilla of the wings. The abdomen is bright ochre yellow with 

 a row of brownish black spots along the middle of the back, the spots 

 transverse, four or five in nnmber, the hind ones largest. The underside 

 is pale brown with the edges of the segments yellow. The wingn are 

 brown, slightly pale towards their hind ends. Their base is white, which 

 color near the middle of cacli wing is prolonged backwards into a long 

 acute point, forward of which are two long egg-shaped brown spots placed 

 side by side, and on the outer edge are two larger brown spots slightly 

 parted from each other by a curved line, with a fifth spot on the inner edge. 

 Towards the middle of each wing on the outer edge are two large white 

 spots of an irregularly triangular form. Beyond these, crossing the wing 

 transversely from the outer margin to the inner angle is a wavy white band 

 which is thickened at its ends. From the middle of this band a curved 

 branch extends forward and inward to the inner margin; and from the 

 same point on the opposite side of the band another branch extends back- 

 ward, nearly to the hind edge?, when it abruptly turns outward and forward 

 and then outward and backward, reaching the outer margin of the wing 

 forward of the tip. In the closed wings these markings upon their hind 

 part are observed to be beautifully symmetrical, having some resemblance 

 to the Greek letter omega with a bar placed horizontally across its middle. 

 The lower wings are deep ochre yellow with four large round blackish blue 

 spots having a black margin, whereof three are situated in a row forward 

 of the hind margin, the inner one of these being the smallest, and the 

 fourth one, wiiich is slightly transverse, is placed forward of the centre. 

 The undersides arc colored and marked similarly but much more pale and 

 dim. The legs are brown with the thighs crimson except upon their under- 

 sides, and the shanks and hind feet arc yellow on their undersides. 



In respect to its colors and spots, this moth is truly protean, varying to 

 an extent which is most astonishing. Thus the fore wings are sometimes 

 black instead of brown, with all vestiges of the white spots and rivulets 

 upon them vanished. In other instances they are of the same bright yellow
