Moth. — Three S , two 2 . Fore wiugs more decideillj^ pale olive-green thau any otlier.s of tbe 

 ;geuus, with distinct black lines and markings arranged nearly as in H. obUqiia. Palpi extending 

 but little beyond the head, gray, black along the upper edge and on the side of the second .joint; 

 third joint rather short, acute, grayish. Thorax greenish gray; tegulic edged with dusky brown, 

 and a dusky brown transverse oval ring over the mesoscutum ; a smoky brown spot on the base 

 of the abdomen. 



Fore wiugs a little sharper at the apex than in H. pbliqua, the outer edge being oblique, as in 

 that species, and the costal edge straight; the wing is of a decided pale olive-green tint, especially 

 in the middle of the wing. At the base of the wing is a black dot, from which a narrow black line 

 passes out just behind the cubital vein, a little way beyond the basal line. This liiie is double 

 and is represented by two black scallops, one on the costal and the other on the median space, 

 not passing farther back across the wing toward the internal edge. A second distinct black 

 double Hue on the inner third of the wing, somewhat curved in its coarse, and consisting of three 

 scallojis, one on the costa, one in the median space, and the third, slightly curved, scallop in the 

 internal s])ace. The discal mark is a conspicuous, long, curved black liue, just within which is a 

 small dilfuse smoky patch, connected on the costa with a double smoky line. Estradiscal line: a 

 •double one of well-marked deep scallops curving inward behind the discal space, and ending on 

 the outer third of the internal edge; within this curved portion is a parallel row of dusky scallops, 

 situated directly behind the discal mark. Between the discal mark and submarginal line the 

 wing is (piite clear and greenish. A distinct black line beginning on the first cubital vein and 

 curving forward and ending on the apex, and sending a black slash along the sixtli subcostal 

 venule. Beyond this line is a broad dusky shade bounded externally by the marginal row of 

 distinct black scallops, which are much deeper than in H. ohJiqua. The costal edge is marked 

 with alternate dark and light short lines. 



Hind wings in S snow white, with the costa blackish, and a dark dot on the internal angle; in 

 the 9 sordid white, with a dark line across the middle, and the outer margin of the wing du.skj' 

 brown, with a black spot in the internal angle. 



Under side of the fore wings dusky on the costal region, the discal mark and dusky sub- 

 marginal band showing through. The rest of the wing is whitish. The hind wings are whitish, 

 except the costal region, which is whitish, and iu the 9 the wings are more dusky. The outer 

 margin of both wings is dusky, and the only whitisli portion on the under side of the fore wings 

 is tlie large oblique subapical shade, while the base of the hind wings is whitish. 



Expanse of wings, S 45 mm., 9 55 mm. ; length of body, $ 21 mm., 9 23 mm. 



This superb and beautifully marked species is at once recognized by the pale, rich, olive-green 

 hue of the thorax and fore wings, with their distinct black markings, including the black linear 

 discal mark; by the often snow-white hind wiugs, and by the deeply scalloped marginal black line. 



It dirt'ers from H. obliqua not only by its olive-green tint, but by the less curved inner line on 

 the fore wings, by the nu)re deeply .scalloi>ed marginal liue, and by the white hind wings of the 

 male, as well as other minor peiuliarities.
