Cymatophora polygrammakia, .ip. nov. Plate 11, fig. 19. 



2 £ . — This species is closely allied to C. humaria, but it is a little Larger, 

 and the apex of the fore wings is rounder, the outer edge a little more oblique, 

 while the outer edge of the hind wings is decidedly fuller and more distinctly 

 scalloped. The body and wings are clearer white than in humaria, and of 

 much the same tint as in larvaria. The basal line on the fore wings is more 

 curved, less oblique, and not accompanied by a brown line as in humuria. A 

 median, narrow, dark hair-line absorbs the discal dot. The arrangement of 

 this and the extradiscal line much as in humaria. Extradiscal line much more 

 oblique and less deeply sinuous than in humaria, and accompanied beyond by 

 a dusky but not brown shade. The usual submarginal zigzag broad line. The 

 marginal scalloped black line is very distinct, much .as in larvaria. Kind 

 wings with an inner straight line ; a small, black, elongated, discal dot, not 

 annular, as in humaria and larvaria; beyond is the extradiscal line, less angu- 

 lar than in larvaria; beyond this line, marked as in the fore wings. Beneath 

 white, the hind wings clear, not lineated; the fore wings white, but a little 

 dusky. Discal dots present on both wings. The head is pale on the vertex, 

 brown in front, and the abdomen is whitish, banded above with black trans- 

 verse lines, with a pair of twin black spots on the white pencil of the hairs. 



Length of body, £ , 0.53; fore wing, £ , 0.75; expanse of wings, 1.60 

 inches.

This fine species is whiter than usual, with the lines arranged as in lar- 

 varia, but without the fawn-brown bands of that species, and with the outer 

 edge fuller and more distinctly scalloped, while the discal dot on the hind 

 wings is not annular, being a simple dark spot.
