NORTH AMERICAN ACROLOPHIDAE — ^HASBROUCK 609 



Remarks. — This species undoubtedly ranges southward into 

 Mexico. It is generally related to punctellus, the two comprising a 

 small species group. This group is related to those species having 

 shortened labial palpi, naked eyes, simple antennae with segments 

 encircled by rings of scales, and fused gnathos. In addition, the 

 Jurcatus-punctellus species group is characterized by a type of ob- 

 scurely bifid uncus in which the furcae are closely appressed and 

 superficially appear simply as a single process with a median longi- 

 tudinal suture. These two small species may be easily distinguished 

 from one another, as well as from the other acrolophids treated here, 

 on the basis of their harpes and aedeagi. The elongate genital 

 capsule and especially the long, slender aedeagus of A. furcatus are 

 somewhat similar to those of variabilis, but the genital and external 

 characters of these two species are otherwise quite distinct. 



Mr. Tams of the British Museum (Natural History) has sent 

 photographs labeled ''furcatus Wals., type" which show the adult cf" 

 and its genitalia. These photographs easily confirm the identity of 

 this species.

Busck's original description follows: 



Neolophus punctellus — Antennae simple in both sexes, thick, with closely set 

 whorls of short scales which give an appearance of serration; ochreous gray. 

 Labial palpi in the males long, slightly recurved, reaching vertex, closely appressed 

 to the face; in the females much shorter, porrected, terminal joint deflected. The 

 palpi are slightly lighter than the head and thorax, which are covered with light 

 fuscous white-tipped scales; thorax smooth. Fore wings appear pearly, light, 

 whitish fuscous, irregularly and sparsely dotted with black scales; under a lens 

 it is seen that the scales are of different shades of brown, each tipped with very 

 light, nearly white, slate-color, except the few deep black ones, which are slightly 

 metallic. CiUa blackish brown. Venation normal, with 12 veins, 7 to termen 

 just below apex, 8 and 9 stalked, lb furcate at base. Hind wings ochreous brown, 

 with 8 veins, all separate; 3, 4, 5, 6, and 7 nearly equidistant and parallel from 

 the end of the cell; a forked discal vein to vein 4 and to just below vein 6. 

 Abdomen dark fuscous above. Under side of body whitish. Legs whitish, 

 sprinkled with fuscous; tarsal joints dark brown, tipped with white.
