hook twice as long as broad, equal on the l)asnl lialf, tai'cring on tlie next quarter 

 only, blunt, attingent and upturned at the tip; lateral arms perfectly connate 

 with the hook throuirhout. Clasp.s more than lualf as long again as broad, nearly 

 equal, a little concave beyond the middle below, the lower posterior angle very fully 

 rounded, the upper posterior angle produced to an incurved, depressed spine, overlaid 

 by the incurving upper posterior lobe, which resembles it on a larger scale. 



Described from 49 3 , 29 9 . 



Accessory sexual peculiarities. The discal stigma of the male has been described 

 under the wings ; the scales contained in it consist of very slender, jointed threads, the 

 joints faintly fusiform (50 : 3 b) aud of spatulate rods or scales, the spatula more or 

 less gradn.ally developed (3 c, e), found in the heart of the stigma; at the extreme base 

 some subfusiform, two-pronged, slender scales (3 f), as well as scales of large size, 

 either enlarging gradually from base to apex (3 g) , or equal throughout (3 d) ; the 

 truncate apical margin more or less abruptly waved ; in the fteld below the stigma are 

 found some long, triangular scales, finely striate, with waved reflections which con- 

 verge more rapidly next the base than at the apex, where they are nearly longitudinal. 



Melanic variety. Tiiymelicus my.stic wektamoo. Mr. Lintner has obtained a 

 single specimen which appears to be a melanic form of the ?. It is of a nearly uni- 

 form, dark, lustrous brown, the basal half of the fore wings with a warm flush caused 

 by a rather liberal sprinkling of tawny scales ; the yellowish markings of the fore 

 ■wing of the normal type are present in a greatly reduced form, closely resembling 

 those of L. manataaqua, and consisting of a small spot at the tip of the cell, and simi- 

 lar, nearly ei|ual spots in the middle of the outer half of the wing, three depending 

 from the costal margin and one near the base of each median interspace ; on the hind 

 wings the cellular spot is indistinct and the extra-mesial band narrow and broken into 

 vaguely defined spots. Beneath, it diflers from the normal type in noway excepting in 

 the diminished extent of the extra-mesial markings of the fore wing. 



Suffused variety. Tn-i-MEiJcus mystic xubs. A female under examination has 

 the upper surface of the fore wings almost uniformly flecked throughout with tawny 

 scales on the basal half, and with tawny yellow scales on the outer half, excepting for 

 the following markings : the usual dusky patch in the interspace beyond the cell, 

 which here extends over the extremity of the cell, and includes there a small quadrate 

 yellow spot, and a continuation of the same below the cell corresponding to the outer 

 parts of the usual patch at this place; the middle of the outer half of the wing has a 

 transverse series of yellowish spots, larger than those described in the melanic female, 

 but much smaller than the normal type, and with confused borderings, especially out- 

 wardly. The hind wings have only a flecking of tawny yellow scales in the outer half 

 of the wings, which, with the greenish tawny scales which give the whole wing an 

 olivaceous ai>pearance, slightly contrast with the grayish aspect of the fore wings. 



Beneath, the wings are nearly of a uniform, very pale grayish fulvous, but the under 

 half of the fore wings, except outwardly, is slate brown, and the light spots of the upper 

 surface of the fore wings are repeated, rather faintly, beneath, while a row of similar, 

 faint, obscure dots represent the position of thp extra-mesial band on the hind wings. 



Egg (66 : 20, 24). Cells irregularly hexagonal, averaging .03 mm. in diameter, their 

 surface uniformly covered with exceedingly delicate, frequent punctuations; inner 

 cells of micropyle (69: 13) eight in nural)er, kite-shaped. .0113 by .021 mm. in size, 

 every alternate one furnished with a micropylic canal at outer extremity ; these are fol- 

 lowed by pretty regular, hexagonal cells at first longer than broad, .019 by .025 mm., 

 increasing slightly in size away from the centre, until they merge almost insensibly in
