NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 535 



encircled by a ring of scales. Although not forming a species group with 

 any other acrolophid, texanellus exhibits certain affinities ^vith propin- 

 quity in regard to general habitus, genital structure, and geographical 

 distribution. However, the two species may be easily separated on the 

 basis of antennal structure and less easily by differences in genital 

 structure and the generally smaller size of texanellus. Although the 

 genital characters of texanellus are both distinctive and consistent 

 throughout my series, the size and general habitus of the moth vary 

 considerably over its rather wide geographical range. 



The type cf of A. hulstellus, in the U.S. National Museum, is 

 labeled "type no. 403, Indian River, Florida, Beutenmueller Collec- 

 tion," and is equivalent to my conception of texanellus on the basis 

 of its genital and antennal structure. The antennae are both unusual 

 and characteristic in approaching a unipectinate condition while 

 having each segment completely encircled by a ring of scales. Also 

 in the U.S. National Museum is a slide of cf genitalia, labeled 

 ^'Acrolophus hulstellus Beut., Plummers Isl., Md., Coll. A. Busck," 

 which I found to be identical with my conception of the cf genitalia 

 of texanellus. Thus, hulstellus Beutenmiiller should be considered 

 a new synonym of texanellus (Chambers). 



The description of Dyar's Atopocera harnesii was based on a single 

 cT specimen from Kerrville, Tex. The wing expanse was hsted at 

 20 mm. Presumably it was named after Dr. William Barnes, from 

 whom the specimen was received. The type, at the U.S. National 

 Museum, is labeled "type no. 5347, Kerrville, Texas." Its genitalia 

 were removed and mounted on a slide by August Busck on Oct. 11, 

 1933. After examining the moth and the slide, I was able to confirm 

 the identity of bamesi, which, like the type of hulstellus, is equivalent 

 to my conception of texanellus. Thus, harnesi (Dyar) should be 

 considered a new synonym of texanellus (Chambers) .

Figures 39-42 



Male. — Head, labial palpi, antennae, and thorax ochreous suffused 

 with fuscous. Labial palpi elongate, recurved back over head and 

 extending to or slightly beyond center of thorax, closely appressed to 

 head and to each other although not appressed to thorax, very densely 

 clothed with scales. Eyes large, protruding, rather densely setose, 

 weakly lashed. Antennae simple, with each segment globose and 

 completely encircled by distinct ring of scales. Fore wings with 

 variable coloration, commonly pale bro^vn and indistinctly suffused 

 with oclu-eous patches. Hindwings and fringes brown. Abdomen 

 ochreous. Wing expanse: 14 to 17 mm.
