trianjinlar patch, resting on the submediaii nervurc, its sides nearly equal, especially in 

 the (J , vhcre it is largest, Ijordcred Avitliout by blackish clouds, and -within l)y a 

 blacliisli Held which occupies tlio wliolc of the lower half of the base of the wing in 

 the ? , but is intensified on or confined to the neighborhood of the median nervure in 

 the i \ fringe blackish fuscous toward the base, but otherwise agreeing with that of 

 the upper surface. Hind loings with tlie discal spot nearly always present, and tlie 

 band in outer half of the wing dill'oriiig somewhat from that on the upper surface; 

 tlie spots vary in color from silvery wliite to straw yellow, and are usually more inde- 

 pendent tlian aliove; they form al)eut series, a little narrower and longer than above, 

 with nearly equal limbs, the upper straight, the lower at a right angle or sliglitly more 

 than a riglit angle to it, and slightly arcuate, the concavity outward ; tlie spot beyond 

 the cell forms the angle of the series, and is situated a little beyond the middle of the 

 interspace; there are two spots above It. usually more separated than those of the 

 lower limb, the costo-subcostal interspace being furuished with one; so also, at the 

 other extremity of the baud, the spot in the upper half of the medio-submedian inter- 

 space is accompanied by a smaller, vague spot in the lower half of the intei-space, 

 slightly nearer the outer border. Basal half of the fringe blackish fuscous, beyond 

 similar to the upper surface of the same. 



Abdomen black, almost entirely concealed on the side, and to a considerable extent 

 above, with fulvous scales ; base covered with dark olivaceous hairs ; beneath covered 

 with tawny scales, and toward the base with hairs like those on the thorax. Upper 

 organ of the male appendages (37: 26) with the centrum rather deeply sulcate above, 

 the hook very large and broad, as long as the centrum, but a little longer than broad, 

 pointed, and a little hooked at the tip ; lateral arms together scarcely one-fourth as 

 broad as the hook, extending just as far as it. Clasps two and one-half times longer 

 than broad, not half so broad at tip as at base, the upper margin very broadly rounded, 

 with a minute denticle at base, the broad, upturned, triangular, sharply pointed tooth 

 of the apical lobe preceded b}' a slight denticle at the exti-emity of tlie upper margin, 

 and interiorly by a row of four or five blunt denticles on the recurved edge of the 

 lower margin.

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

 scribed under the wings ; the scales contained in it consist of jointed threads, with the 

 joints of unusually large size and distinctly fusiform (51 : le) situated in the heart of 

 the stigma, and accompanied by awl-shaped rods (1 i) expanding at the extreme tip ; at 

 the extreme base of the stigma are found only rod-like scales, of nearly equal width 

 at the tip, truncate (1 h) or two-pronged (1 a) ; at the extreme tip are found somewhat 

 similar two-pronged scales, enlarging vei'y gradually, but considerably, from the base 

 to the apex, the apical prongs being lateral and slight, and separated by a broad, 

 rounded tooth (lb); in the field below the stigma are found either large (luadrate 

 scales with the apical margin somewhat similar to those last mentioned (1 g), or 

 long and rather slender scales, enlarging more or less apically, with entire but sub- 

 truncate outer margin (1 c, d) ; besides, there are other triangular scales, with convex 

 margins and fine converging striae (1 f). 



Egg (66: 33). Cells .0127 mm. in diameter. Surface profusely punctuate in the 

 most minute aud delicate manner ; the punctuations are shallow, circular, and. 004 mm. 

 in diameter. The micropyle (69:11) consists of a cluster of about half a dozen 

 pores within a diameter of .0115 ram., surrounded by an annulus of elongated, pentag- 

 onal cells, without punctures, occupying a field .027 mm. in diameter; around them
