52 AMERICAN LEPIDOPTERA. 



28. H. simulella n. sp. (Plate III, fig. 28.)— Palpi of moderate 

 length and thickness, terminal joint two-thirds (male) or three-fourths 

 the length (female), of the second; white, densely suffused with 

 dark fuscous-brown externally, speckled with fuscous within, apex of 

 second joint white. Head, thorax and basal joint of antennae white, 

 speckled with fuscous scales. Shaft of antennae slender, brownish, 

 paler beneath. Forewings rather narrow, costa nearly straight from 

 the base, apex pointed; ground color white, sparsely (male) or densely 

 (female) speckled with dark brown scales ; markings pronounced, 

 dark purple-brown, as follows ; a well marked spot below the costa 

 and very near the base, an irregular, not sharply defined, and out- 

 wardly angulated fascia, the costal portion commences at one-third, 

 extends obliquely outward towards the fold, along which it forms a 

 streak, the dorsal part is subquadrangular and begins at one-fourth 

 from the base, in the basal space are two dashes, one immediately 

 above and the other a little nearer the base, and immediately below 

 the fold, just beyond the middle, and a trifle nearer the costal margin 

 is a small, inconspicuous spot, and at the end of the cell two very dis- 

 tinct spots, midway between the discal spot and the costal margin is a 

 blackish line which extends as far as the end of the cell, another similar 

 line immediately below the costal margin , well marked nebulous patches 

 in apical part of wing, giving somewhat the appearance of an out- 

 wardly convex fascia ; cilia pale yellowish-gray, basal half sprinkled 

 with fuscous scales, interspersed with white. Hindwings as wide as 

 the forewings, not acutely pointed, costa refuse in outer half; pale 

 gray, dusted with fuscous; cilia 1, grayish, paler towards the base 

 with pale basal line. Abdomen above white, lightly dusted with fus- 

 cous, anal bush grayish. Underside of body and legs white, the former 

 lightly suffused with fuscous, the latter speckled with dark brown 

 scales, leaving a median oblique spot on posterior tibiae externally 

 and apices of tarsal joints white. Expanse 16.0 mm., 0.64 inch. 



Hab. — Arizona (Williams), Texas (Fedora). 



Two specimens in the Nat. Mus. Coll., and a male in my 

 own. The latter has but one forewing le f t, the ground 

 color is white with scarcely any sprinkling of dark scales, 

 the markings less pronounced than in the female. A female 

 specimen in my collection from Stockton, Utah, collected by 

 Mr. T. Spalding, has the wings narrower, and the forewings 

 are more densely sprinkled with dark fuscous scales, I 

 refer it doubtfully to the species under consideration. 



29. H. messelinella n. sp. (Plate III, fig. 29.)— Palpi of but 

 moderate length, sordid white, the second joint incrassate towards the 

 apex and roughened beneath with scales, dusted externally with fus- 

 cous, terminal joint scarcely more than half the length of preceding
