194 Psyche [October 
This species, so frequently confused with lugens and separatus, 
may at once be separated from the former by its much smaller 
size and gray color, and from separatus by the fact that “the 
prothoracic tegule have no obviously yellow marginal spots.” 
In Coll. Barnes are 4 &@ and 4 9 from Kerrville, Texas. 
(22) H. separatus Neum. New Mexico. 
This species was long regarded as equivalent to andromede 
Bdv.—lugens Walk. It is however smaller and lighter in color 
than this form, and is most readily distinguished by the presence 
of a distinct yellow marginal spot on each side of the collar; these 
spots are always vestigial in the nearly allied species. Dr. Barnes 
possesses 2 o and 3 Q from New Mexico. 
(23) H. istar R. & J. Tex. 
This is the largest species of the group and is represented in 
Coll. Barnes by 2 “and 2 2, from Kerrville, Texas. Apart from 
difference in the genitalia it is separated from its near allies by 
the fact that the interspace between the black middle stripe of 
the prothoracic tegule and the black upper edge is dark brown, 
much deeper in color than the thorax and adjacent parts. It 
also lacks the black longitudinal line in the upper portion of 
cell on primaries. 
(24) H. chersis Hbn. 
(a) chersis pallescens R. & J. N. Mex., Ariz 
(b) chersis oreodaphae Hy. Edw. Cal. 
(c) chersis chersis Hbn. Eastern States. 
A careful examination of the specimens in Coll. Barnes named 
oreodaphe revealed the fact that with the exception of 2 2 they 
were all referable to the form asellus of perelegans. These 2 Q’s 
belong to the new form, pallescens. Apart from their larger size 
and the marked difference in genitalia they may be most easily 
distinguished from asellus, to which they bear a strong super- 
ficial resemblance, by the fact that the gray color of primaries 
is much less even than in asellus and always shows whitish mark- 
ings below the black dashes, exactly as in typical chersis. The 
broader white band distal to the black marginal line on prim- 
aries, as well as the faint black middle line on patagia by which 
Rothschild & Jordan differentiate asellus, are not always very
