AMERICAN LEPIDOPTERA, 181 



wnrdly over the submedian fold on to the median space of the wing, 

 its furcation taking place at a point beneath the basal half-line, whence 

 the lower branch is thrown off downwardly obliquely on to the internal 

 nervure. Subterminal space nearly filled with a diffuse deep brownish 

 shade which, below median nervule, is narrowly continued outwardly, 

 where it is slightly waved, to internal margin. Transverse anterior 

 line formed of two distinct, dark brown lines, divaricate on costa, 

 where they are also more faintly expressed, thence running approxi- 

 mately and slightly irregularly to internal margin. Below median ner- 

 vure and along costa, the median space is shaded with olivaceous. 

 Centrally the costa is free from the alternate dark and whitish cinere- 

 ous streaks which characterize II. obliqua. A distinct, black, trans- 

 verse discal line, beyond which, the wing is shaded with bright brown 

 below the subcostal nervule to external margin. The black scales are 

 continued below the streak over second median nervule, and there is 

 a second prominent and parallel black streak on the interspace below. 

 The bright brown color suffuses the wing terminally until above third 

 median nervule, below the latter this is again cinereous, dusted with 

 olivaceous, and the lunate transverse lines are brought into relief by 

 pale scales. Surmounting the discal streak is a dark geminate shade 

 which, while distinct on costa, becomes obsolete inferiorly below medi- 

 an nervure. The transverse posterior line is generally indistinct, and 

 consists of a double series of regularly lunate brown lines, apparent 

 over the bright brown terminal shade, but indistinct inferiorly. A dif- 

 fuse, subterminal, black shade, analogous to that in H. obliqua, but 

 less distinctly expressed; there is a series of black, longitudinal, inter- 

 spaceal dashes, of which the lowest is on the interspace above first me- 

 dian nervule. The nervules are obsoletely picked out by pale scales, 

 and there is a slight aggregation of these latter at apex. An even, 

 distinct, continued, narrow, brown terminal line. Fringes, dark oliva- 

 ceous cinereous, with a distinct, basal, darker line; at the extremity of 

 the nervules the fringe becomes obsoletely darker colored. Seconda- 

 ries, smoky grey, with a median pale shade and with longer pale hairs 

 over the base and along internal margin. Terminally the color of the 

 wing is darkest, deepening to a dark, marginal shaded line along the 

 external edge. This marginal line is broader than usual, continued 

 along costal margin, and obsoletely preceded along external margin by 

 a pale shade; it is also slightly lunate on the interspaces. Fringes, 

 cinereous. ti})ped with a paler shade. 



Under surface, cinereous, with obsolete ornamentation. Primaries
