or bronze along the back, green on the side and beneath, while a conspicuous yellow lateral 

 line extends from the tip of the anterior to that of the posterior horn or projection. It has 

 no lateral eye-like red spot on the side of the first abdominal segment. 



The larva, however, so far as we can judge from a figure alone, is evidently closely alhed 

 to Aglia tau, as is the moth. 



It will be a matter of the greatest interest to have the larval history of this genus worked 

 out; we should expect that its freshly hatched larva is armed with spines as in Aglia, which 

 are discarded at the last molt. It is a matter of the utmost importance that the entomologists 

 of Chile should secure, the eggs and rear the larva, securing the larva; in all stages and the pupa, 

 and to ascertain whether the pupa is subterranean or protected in a cocoon.

Imago. — "The most obvious differences which separate this species at a glance from any 

 of the varieties of E. venusta (Walk.) are its small size (barely half that of venusta), strongly 

 dentated margins to all wings, and absolutely tailless hind wings in both sexes. 



"Male: Fore wings deep rufous chocolate, a large round white spot situated at apex of 

 cell, beyond which is a transverse bar of darker chocolate. Hind wings orange yellow, with 

 the outer third reddish chocolate, and a central narrow transverse band of the same color. 



"Underside similar, but all the colors and markings more mixed and indistinct. 



"Female: Fore wings reddish gray, with a dull yellow round spot at the apex of cell, 

 between which and the base of the wing are two indistinct red transverse fines, and beyond 

 the cell again are two broader and more distinct ones. 



"Hind wings reddish gray, more brown toward the margins, and crossed by two very 

 indistinct transverse fines. Under side identical. 



"Expanse, o* 1 i inches = 38 mm.; 9 2 inches = 51 mm. 

 "Hab. Chile (in coll. Staudinger)." (Rothschild.) 



This is probably the type of quite a distinct genus; the fore wings are not falcate, and the 

 hind wings besides being tailless are quite different in shape. 



[It is said to look like an Orgyia.]

The type of this genus is N. philippii Izquierdo, 1896, from Chile. Izquierdo describes 

 the metamorphoses.]

Head: When denuded the front is somewhat shield-shaped or subtriangular, moderately 

 wide, a little wider than one eye seen from in front, narrowing a little toward the oral region. 

 Antennas of S bipectinate, either with rather short pectinations on basal three-fourths, leaving 

 the tip filiform (Imbrasia) or pectinated to the tip and more or less plumose, the pectinations 

 being unusually long and slender; those of ? subsimple (or simple). 



Palpi three-jointed. 



Wings large and broad; fore wings with 11 veins, broad, large, as a rule about one-half 

 as wide as long; the costal edge more or less curved; the apex either subacute (Lobobunsea) or 

 acute (Bunaea) ; the outer edge entire ( Vsta) or excavated, and in certain genera (Lobobunsea 

 and Bunaea) scalloped. 



Hind wings either normal, the apex squarish, the outer edge slightly convex (Vsta), or 

 the apex is rounded, and there is a decided angle in the outer edge (Girina) or a short tail 

 (Imbrasia), but in the other genera the outer edge is convex, full, though Gynanisa ethra has a 

 short tail.
