NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 547 



Clemens' original description of plumifrontellus, which probably 

 did not actually appear in print until sometime in 1860, is quoted 

 below: 



Anaphora plumifrontella — Labial palpi reddish brown. Thorax dull brown 

 tinged with reddish. Fore wing rubescent and maroon brown intermixed, the 

 former hue prevailing along the fold, at the base along costa and disc, dusted 

 with dark brown ; with a dusky or dark bro'miish spot on the end of the disc, one 

 about the middle of the fold and another near the base. In some specimens these 

 ■spots are quite indistinct. Hind wings dusky brown. Exp. al. 17 lines [about 

 36 mm.]. Female not known. 



Clemens mentioned elsewhere in his paper that the labial palpi in the 

 cf were "greatlj^ developed, ascending and thrown back on the dorsum 

 of the thorax, which they equal in length." Clemens' figure for 

 plumifrontellus, an engraving of the head of the cf , was subsequently 

 published by Stainton (1872, p. 60, fig. 3) in his collected edition of 

 the late Dr. Clemens' writings on North American Tineina. In 

 the same paper describing plumifrontellus, but preceding his erection 

 of the genus. Anaphora, Clemens stated: 



Plumifrontella is found here (Philadelphia) in June and July, when it may be 

 taken at light. I am unacquainted with the embryonic history of the species 

 described, and have never met with the female Plumifrontella. The genus, I 

 think, belongs to the group Exapatidae, and as the females in some of the genera 

 are apterous, that of Plumifrontella may be unsuppUed with wings. The antennae 

 should be examined very carefully, otherwise their peculiar structure wiU be 

 overlooked and mistaken for simple, filiform organs. 



Walsingham (1887, p. 149) made the following comments on 

 Clemens' original description of plumifrontellus: 



To this description we may add that the antennae are compressed, not strictly 

 serrated throughout, but only slightly so towards the tip; lateral claspers spoon- 

 shaped, rather abruptly dilated and bent, with a pair of supplementary claspers 

 above them, nearly as long as themselves; uncus double, the points parallel and 

 divided. 



At the same time, Walsingham (1887, pi. 7, figs. 5-5e) furnished a 

 number of illustrations for this species. These consisted of: figure 5 

 adult cf , dorsal aspect (in color); figure 5a head of cf, lateral aspect; 

 figure 5b head of 9, lateral aspect; figure 5c cf genitalia-uncus and 

 cucullus of harpe, with "supplementary clasper," lateral aspect; 

 figure 5d 9 genitalia, ventral (?) aspect; and, figm-e 5e neuration of 

 forewing. 



Beutenmiiller (1889) described the 9 of plumifrontellus as follows: 



The undescribed 9 of this species differs from the cf only in having long 

 porrected labial palpi, and the markings of the primaries much suffused with 

 the ground color. Expanse, 19 mm. Length of palpi, 5 mm. 



One example. Coll. Beutenmiiller. Taken at Parkville, L.I., N.Y., July, 

 1888. Another specimen, much larger than the one I possess, is in the collection 

 of Mrs. A. T. Slosson, taken in the White Mountains, N.H.
