The harpes of male are rather broad at middle, narrowing rapidly 

 to a narrow, somewhat rounded tip, which is inwardly fringed with 

 spinules. The clasper arises from the middle of inferior margin, 

 extends about three-fourths across the harpe, is then cut abruptly 

 from the inner edge, the outer produced into a moderately long, 

 somewhat curved, acute spur. In the male, too, the primaries are 

 decidedly narrower than in the female, or in the more typical species 

 of the genus.

'"Allied to atricollaris, but smaller; the collar entirely whitish gray, head 

 blackish. Eyes naked; the short fore tibise with a terminal claw; gray, of a 

 whitish tone ; under the glass the surface of primaries is whitish, sparsely mixed 

 with black scales; the markings hardly visible to naked eye; under the glass 

 the black, perpendicular, thread-like t. a. line is seen, and attached to it a sub- 

 rounded, enclosed concolorous spot, the claviform. Similarly the concolorous 

 orbicular and reuiform may be seen ringed with fine black circles, the stigmata 

 subequal, orbicular round, reniform upright, hour-glass shaped. Median space 

 narrow, t, p. line indicated ; a black dash from the reniform outward tapering to 

 external margin. Similar fine interspaceal shades give the terminal space a 

 slightly rayed appearance. Hind wings whitish, subpellucid. Beneath pale.

"This species is interesting as affording an ally to atricollaris."
