purple brown outside the outer scalloped median line, which runs from costa 

 to inner margin. Inner line single, faint, irregular. A discal dot. Hind 

 wings with medial line narrow and indistinct, faintly washed with purplish » 

 subirrorate. The female is smaller than male, paler, more yellow, still the 

 basal and terminal field of primaries show a purplish shade. The hind wings 

 are paler, more yellow with yellowish fringe. Beneath bright ochre yellow, 

 strigose; in male fringe and apices purplish. A common extra mesial ochre 

 line; faint discal dots. Male expands 40, female 34 mil. New Mexico and 

 Arizona. 



This may be known by the primaries being more or less purplish at base 

 and terminally, the wing being divided into three fields by the two median 

 lines, the outer oblique, well removed outwardly, rather regularly scalloped. 

 The ground color is rather faded yellow, somewhat bright on the wide median 

 space. The long palpi projected straight forwards, the converging facial 

 hairs, the long, heavily pectinated plumose male and simple female antennae, 

 and the sexual difference in shape of fore wings, prevent me from referring the 

 moth to any genus in Dr. Packard's Synopsis, nor can I recognize the species, 

 which must be very common, among his figures or descriptions. This is one 

 of the higher genera of the family, and should be catalogued among the first, 

 after Tetrads and Angerona. It is singular, as before stated, that the editors 

 of the Brooklyn "List," who show so little freedom of thought in their work 

 and take so many liberties in their preface, should have followed Dr. Pack- 

 ard's arrangement in his monograph, and commenced with the lower genera. 

 Were we in possession of a knowledge of the sub-order from the earliest 

 time, such an arrangement would be philosophical ; and, like the geologists, 

 who commence with the primary rocks, and finish their exposition with the 

 quartenary formations, we could ascend from the earliest to the latest species. 

 But in the vast majority of works on botany and zoology, a linear arrange- 

 ment commences with the highest groups, which are assumed also to be the 

 latest to come into existence. 



Chryseudeton Avernalis n. s. 



No ocelli. Pale ochrey-brown. A diff'use white sub-basal band, includ- 

 ing a brown spot. A median white band angulated at the middle, crossed 

 by a longitudinal discal black streak. The outer band is exserted over 

 median veinules, and dyed within by brown scales. Subterminal white band 

 tapers inferiorly, and does not reach the internal margin. Fringe brown. 

 Hind wings white, with a median patch dotted with black scales ; a yellow 

 terminal line. A row of black spots on the margin, less conspicuous than 

 usual, but faint traces of metallic scales. Fragments of two brown inner 

 fascise, marked on internal margin. Beneath powdered with brownish. The 

 white outer and subterminal bands make a V-shaped mark on fore wings 

 outwardly. On secondaries, the terminal dots reduced. Two specimens. 

 Expanse 22 mil.
