thin, setiform, gray. Palpi very pale, as long as the thorax, curved 

 upwards, slender, gradually pointed ; third joint about one-half the 

 length of the second. Legs concolorous with the thorax, only the 

 anterior somewhat fuscous anteriorly ; posterior tibiae slender, feebly 

 hairy above; feet not spotted. Abdomen short, blackish-gray, anal 

 bush paler. Forewings three lines long, narrow, not widened, some- 

 what rounded at its narrowest end, same color as the thorax. Very near 

 the base of the costal margin is a small, not very conspicuous blackish 

 spot, a much larger and conspicuous spot in the median space before 

 the middle, nearer the fold than the costal margin, a pair of blackish 

 spots at end of cell, close together, above these is a short, not very 

 distinct, dark line. Cilia pale gray. Hindwings to the middle, but 

 little narrower than the forewings thence gradually narrowed to a 

 distinct, though not elongated point, very pale gray, with some lustre, 

 paler towards the base. Cilia pale yellowish. Underside of forewings 

 unicolorous, gray ; dorsal margin paler. Hindwings same color as 

 upper side, somewhat darker along the costal margin. 



Hab.— Texas. 



Two males in Cambridge Museum labeled livorella, but 

 not in Zeller's handwriting, Dallas, Tex. Boll. Zeller states 

 (palpi): "third joint one-half the length of the second," 

 whereas it is nearly as long. Antennas deeply excised above 

 the base, excision with truncated tuft, cilia short. The fore- 

 wings can hardly be called narrow, costa somewhat arched 

 from the base, white, lightly dusted with fuscous, the latter 

 more condensed in basal portion with an ill-defined dash 

 above the fold. The subcostal spot near the base, mentioned 

 in the description is not noticeable, unless it is the supra- 

 plical dash mentioned here ; beyond the darker basal dusting 

 is a relatively wide irregular fascia, shaded externally, espe- 

 cially in costal portion by some dusting. Hindwing as wide 

 as the forewing, pointed ; cilia under 1. Abdominal seg- 

 ments light fuscous, fringed with silvery white scales, anal 

 bush white. Veins 3 4- 4 of hindwing stemmed, 5 out of 

 stem (in one wing apparently free). 



16. H. iceryseella Riley. (Plate III, fig. 21.)— Palpi long, re- 

 curved, second joint thickened towards the apex, terminal slender, 

 pointed, much shorter than the preceding joint; grayish-white sprinkled 

 with fuscous, apex of second, and base and apex of third, paler. Head 

 and basal portion of antennas sordid white, basal joint broad, pecten 

 setaceous, shaft grayish-fuscous outwardly, excised above basal joint
