1 i and 4 9. — A species with unusually lung wings, the apex of the 

 primaries greatly ])n)diioed, wiiile the hind wings are well rounded. The 

 uuilc antennte arc almost sul)pectinated, the bristles arising from acute tuber- 

 cles ; female antcniue filiform. Body and wings snow-white; palpi white, 

 very slender; iVout of head brown-black; four small distinct discal dots. 

 Primaries willi ihree nearly e(iuidistaut, sinuate, wavy, rather broad, oclireous 

 liiK^s: the inner one sinuate, remote from the base of the wing; the middle 

 one runs very near the discal dot, and is less sinuate than either of the two 

 others; outer line deeply curved twice; fringe jiure white. Hind wings like 

 primaries, but with two ochreous lines beyond the distinct discal dot. Be- 

 neath, both wings a little dusky, more or less thickly speckled witli dark scales, 

 with a conspicuous dark hair-line half-way between the discal dot and outer 

 line on both wings. A row of dark marginal spots, as usual, on the upper 

 and under sitle of each wing. 



Length of l.ody, J , 0.37, 9 , 0.25-0.30; fore wing, S , 0.33, 9 , 0.30-0.38; 

 expanse of wings, 0.80 inch. 



Texas, May 2-8, September 24 (Belfrage). 



This pretty snow-white species may be readily recognized by the long, 

 pointed primaries, the slender white palpi, subpectiuated antenna^ and three 

 di.stinct, sinuate, ochreous Ixmds on the fore wings. The fore wings are longer 

 tiuin in A. assalata, while the hind wings are more rounded. It ditlers from 

 A. peralbata, to which it is nearest allied, by the longer and narrower wings 

 and its smaller size. The markings are very similar in the two species, but 

 in hmgipennata the discal dot and extradiscal line of the hind wings are situ- 

 ated farther from the base (»f the wing than in paralhata, this line in longi- 

 pcnnata being a little outside of the miildle of the wing.
