42. H. pusilla n.' sp. (Plate IV, fig. 37.)— Palpi rather robust, 

 scarcely reaching to the lower margin of the antennal insertion, fus- 

 cous, the second joint at apex and within paler, thickened towards 

 the apex and somewhat roughened with scales beneath. Head gray- 

 ish-fuscous, front smooth with a greenish sheen. Antennae stout, 

 light fuscous, with short pubescens beneath, not excised above basal 

 joint, the latter grayish-ochreous, but a trifle longer than wide, pecten 

 gray. Thorax grayish-fuscous, with some lustre, somewhat darker 

 anteriorly. Forewings elongate, pointed ; ground color gray with a 

 faint ochreous tint, dusted with fuscous, costal part of base and extreme 

 costal margin for one-half its length dark fuscous, a fuscous fascia at 

 one-third, rather broad, curved and about equidistant from the base 

 at both margins, first distal spot at outer margin of fascia and midway 

 between costa and fold, distinct, a well-marked elongate spot on the 

 posterior margin of the cell, spots at end of cell confluent, costal and 

 apical portion of wing more densely dusted, especially so above and a 

 little beyond the end of the cell, where it forms a nebulous patch, an 

 elongate spot on the end of the veins, along the periapical margin ; 

 cilia gray, darker towards the base. Underside fuscous. Hindwings 

 under 1, strongly narrowed towards the apex, latter not very acute ; 

 grayish-fuscous; costa nearly straight, scarcely refuse; cilia over 1, 

 gray, yellowish towards the base. Abdomen grayish-fuscous, anal 

 bush gray. Underside of body grayish-white with yellowish tint, some 

 lustre. Legs yellowish-white, suffused with fuscous, median spot and 

 apex of tibia? and apices of tarsal joints paler. Expanse 10.0 mm., 

 0.4 inch. 



Hab. — Texas (Brownsville). 



A male specimen in my collection received some years 

 ago from the late Prof. F. H. Snow. Much smaller than 

 any of its near allies, with palpi and antennae (male) decid- 

 edly robust. In size it comes near to H. ?iana, from the 

 same locality, but is an altogether different species. 



43. H. rufopuiictella n. sp.— Palpi (wanting). Head, basal 

 portion of antennas, thorax and forewings white with some lustre. 

 Basal joint of antennae rather slender, twice as long as wide, pecten 

 setaceous, pale gray, shaft pale fuscous gray with faint annulations, 

 very slender (female). Forewings rather narrow, costa very slightly 

 convex from the base, apex acutely pointed, very lightly dusted with 

 ferruginous scales, a little more evident along the costa and in apical 

 part of wing, an inconspicuous patch of such scales on the fold very 

 close to the base, a short line on the fold at one-third, a rather con- 

 spicuous spot before the middle (first discal) and a little nearer the 

 costa, two spots at end of cell which are connected by a transverse 

 line, before the lower of these, on the posterior margin of cell is another 

 less distinct spot ; cilia whitish. Hindwings a little narrower than the
