the end of the disk, two others to the costa behind the tip and 

 a furcate apical branch near its end, the lower branch running 

 into the apex of the wing. Beneath the apical are five 

 nervules, the posterior two of the median vein arising close 

 together. The submedian forked at the base. 



Head large, smooth, with hair-like scales. Face broad, 

 not tapering, rounded. No ocelli. Antennae about one-half 

 as long as the fore-wings ; basal joint in the $ ciliated in 

 front, rather long, flattened, concave within, articulates with 

 the stalk by means of a nodule, at the junction of which with 

 the stalk, it is sharply excised, and the stalk beneath, micro- 

 scopically pubescent : in the ? the basal joint is long, cylin- 

 drical, stalk scarcely pubescent beneath. Labial palpi cylin- 

 drical, ascending equal to the vertex, rather widely separated ; 

 second joint slightly thickened beneath with scales, rather 

 longer than the terminal ; terminal joint slenderer than the 

 second, smooth and pointed. Maxillary palpi very short. 

 Tongue scaled at the base, as long as the thorax beneath. 



The perfect insects bear some resemblance to those of the 

 genus Gelechia ; they are sluggish in their motions and flight. 



H. chalcofrontella. Fore-wings pale yellowish, dusted 

 with fuscous, so as to produce two or three- ill-defined fus- 

 cous spots along the costa, from the middle of the wing, and 

 one on the middle of the inner margin. Near the tip is a 

 wavy fuscous line, and the ends of the nervules are touched 

 with the same hue. In the middle of the wing is a blackish- 

 brown dot, and usually one of the same hue beneath it in the 

 fold. Above the end of the fold are two blackish-brown dots 

 in the middle of the wing, one above the other. Hind-wings 

 yellowish-fuscous, cilia the same. 



Antennas, basal joint pale yellowish, stalk dark fuscous. 

 Head pale yellowish. Labial palpi fuscous, the end of the 

 second joint pale yellowish, and the extreme tip of the terminal 

 joint yellowish in the $ . 



This insect appears to be a variable one. 1st. Sometimes 

 the wings are entirely fuscous, with but little yellowish, when
