NORTH AMERICAN ACROLOPHIDAE — ^HASBROUCK 645 



eyes, simple uncus, and fused gnathos are quite similar to those of 

 juxtatus. However, the labial palpi of chiricahuae are intermediate in 

 length and noticeably extend onto the anterior margin of the thorax, 

 whereas those oi juxtatus are rather short and barely extend onto the 

 thorax. Further, the genital differences between these two species 

 are quite marked. Their unci, harpes, and aedeagi are respectively 

 distinct. Lastly, the anellus of chiricahuae is unarmed or bears only a 

 faint trace of a juxta. In general, the genitalia of chiricahuae seem 

 more similar to, but still distinct from, those of minor.

Busck's original description follows: 



Acrolophus fervidus — Labial palpi erect, reaching just beyond vertex, loosely 

 haired, light ochreous with dark brown base. Antennae short, stout, light ochreous. 

 Head and thorax reddish ochreous; patagina light ochreous with a reddish brown 

 longitudinal stripe. Forewings whitish ochreous, heavily overlaid with bright 

 reddish-brown scales, especially on basal two-thirds; on the middle of the wing 

 from base to lower corner of the cell is a broad unmottled whitish streak, edged 

 above and below with dark brown; above this is a black longitudinal line from the 

 middle to the end of the cell terminating in a small black spot; veins 2 to 5 are 

 indistinctly traced by dark brown lines; cilia with alternate whitish ochreous and 

 reddish-brown tufts. Hind wings of a rich dark brown color with light ochreous 

 cilia. Abdomen blackish brown above; dusky ochreous below; anal tuft ochreous. 

 Legs clothed with mi.xed ochreous reddish and black hairs. Alar expanse, 28 to 

 32 mm.
