Remarks. — The 9 listed above probably belongs to acornus, although 

 I am not absolutely certain of its correct identity. This species un- 

 doubtedly ranges southward into Mexico. It is closely related to siinu- 

 latus and bicornutus, with which it forms a distinct species group. This 

 group, as characterized in the key, consists of small moths having 

 elongate labial palpi, setose eyes, globose antennal segments com- 

 pletely encircled by rings of scales, and a type of uncus consisting 

 of a single process minutely and acutely bifid at the extreme apex. 



A. acornus may be distinguished from its close relatives, as well as 

 from all other acrolophids, by its characteristic harpe and aedeagus. 

 The name acornus refers to the absence of cornuti in the vesica of the 

 aedeagus of this species.

Walsingham's original description follows: 



Acrolophus (?) simulatus — Head rough; maxillary palpi none; tongue none; 

 ocelli none. Labial palpi recurved over the head and part of the thorax; the 

 second joint very long, roughly clothed with projecting scales beneath; third 

 joint about half as long as the second, brushUke, with very long diverging scales on 

 the underside. Antennae strong, slightly pubescent, somewhat serrated on both 

 sides, especially towards the apex. The anal appendages in the male much devel- 

 oped, the elongated ovate side claspers not reaching beyond the upper shield, 

 which is triangular and pointed. Fore wings with the costa arched, apex rounded, 

 apical margin obhque, sUghtly convex, the dorsal margin somewhat convex, not 

 emarginate before the rounded anal angle. Hind wings ovate, wider than the 

 fore wings. Fore wings with twelve separate veins. The vein from the upper 

 corner of the discal cell in the fore wings ends on the costal margin and is not 

 forked; cell of hind wings not closed. Alternate brown and whitish ochreous 

 patches along the costal and dorsal halves of the fore wings, the paler portions 

 apparently predominating rather more than in Eulepisie cressoni, the darker 

 portions assuming the form of two angulated fasciae; there are numerous raised
