54 AMERICAN LEPIDOPTERA. 



30. H. morrisoni Wish. — " Antennae with moderate pecten ; pale 

 brownish-ochreous. Palpi brownish-ochreous. Head and thorax gray- 

 ish-brown, with paler speckling. Forewings rather narrow, elongate, 

 not widening outwardly ; base white, with grayish-brown suffusion, 

 especially around the margins ; a brownish shade at the base of the 

 costa, a darker streak in the basal third of the fold, diffused and diluted 

 to the nexus ; beneath it a triangular brownish-fuscous dorsal patch 

 arising a little before the middle, directed obliquely outward and end- 

 ing obtusely on the cell at about one-half the wing length ; beyond it 

 a pair of brownish-fuscous spots at the end of the cell, and a few ill- 

 defined similar spots around the apex and termen ; cilia grayish-brown. 

 Hindwings shining, pale brownish-gray; cilia pale brownish-ochreous. 

 Abdomen and legs pale brownish-ochreous. Alar expanse 17 mm." 



Hab. — Arizona. Type. — Male, Mus. Walsingham. 



"A narrow winged species, differing much in appearance 

 from any already described (Walsingham), and quite unlike 

 such exponents of allied genera as I have before me." 



The above is Lord Walsingham's description with com- 

 ments. I have nothing to add ; unknown to me. The peculiar 

 dorsal patch should lead to the recognition of this species. 

 31. H. fluxella Zell. 



Described as follows : 



" Minuta, antennis crassiuseulis, supra articulum basalem squamis 

 ampliatum, non excisis ; alis aut cinereis, striga ante mediam fracta, 

 albida, exterius nigricanti — marginata, puncta disci punctisque duabus 

 geminatis veuag transversa^ coalescentibus nigris ; posticis lanceolatis. 



" Agrees nearly with H. fractilinea in markings, but is smaller with 

 narrow hindwings and more slender abdomen, the antennas, how- 

 ever, are not excised at the base. Palpi more slender than by fracti- 

 linea, bend upwards, as long as the thorax, light gray dusted with fus- 

 cous externally, third joint less than one-half the length of the second, 

 more slender and pointed. Legs pale ochreous-white ; posterior tibiae 

 rough haired, hind tarsi pale fuscous externally, joints pale at apex. 

 Abdomen slender, sides of posterior segments with pale yellowish hairs, 

 anal bush of same color. Forewings two and one-half lines long, gray, 

 darker along the margins; transverse line angulated above the fold, 

 margined externally with dark fuscous, before it and in the fold is a 

 small black dot, and beneath it a short dark line, and behind it, im- 

 mediately above the angle, is a sharply defined black spot ; two con- 

 fluent spots at end of cell, and beneath these a spot on the posterior 

 margin ; a line of non-confluent black spots at base of cilia. Hind- 

 wings about one-half the width of forewings, lanceolate, sharply pointed 

 with distinct anal angle, c?. Texas."
