lion, and its thick but simple male antennae separate this genus from Hype' 

 retis, to which it is closely allied in the form of the wings. 



Larva — Rather thick, ramiform ; head as wide as the body, which is 

 provided with two pairs of long, curved, dorsal filaments arising from the 

 middle of the body. Pupa thick, conical.

8 3 and 2 9. — Pale ochre, with brown veins and transverse strigae; a 

 brown inner line, much curved. An outer sinuate line, with a supplementary 

 line just inside, touching the outer line on the submedian vein and in the 

 extradiscal space, and forming a large circle, one side of which touches the 

 outer line. Beyond the line, the border of the wing is dull brown, with the 

 apical region clear. Hind wings streaked transversely as on the fore wing, 

 with the outer third brown, apex included. Beneath much paler ; veins not 

 colored ; wings speckled and the markings the same as above, but faint ; outer 

 edge of hind wings pale yellow, either with or without traces of outer line. 



Length of body, <f , 0,28-0.33 ; of fore wing, 9, 35-0.45 ; expanse of 

 wings, 1.00 inches.

I am led, from the description, to regard N. expunctaria as a variety of 

 this variable species. This is probably Macaria limbata Wood, Index Ento- 

 mologicus, 166, fig. 748 n, 1839. 



Larva. — Body cylindrical; head large, with two unequal pairs of long, 

 slender, fleshy filaments, situated on the third and fifth abdominal rings, the 

 posterior pair shorter than the others, curled at the end anil finely tuber- 

 culated. Head pale rust-red, marbled with a still paler hue. Head full on 

 each side of the median line, flattened in front. Half-way between the meta- 

 thoracic legs and the first pair of filaments are two subacute tubercles, which 

 are rust-red; when the four filaments are uncurled, they are as long as from
