IiiAGO. Male. Forewinrj broad, triangular ; costa moderately and regalarly 

 arched, the apex acute, exterior margin straight, posterior angle rounded, posterior 

 margin somewhat sinuous, being lobed near the base, and the edge of the middle 

 folded back flat upon the underside, the fold being thickly clothed on its surface 

 and fringed at its free edge with firmly attached long and somen^hat raised modified 

 scales, rendered conspicuous by their rich dark-brown colour and satiny lustre ; the 

 outline of this turned-down fold is marked out on the upperside by a curvilinear 

 groove; first subcostal branch emitted just before end of the cell, second 

 branch beyond the end of the cell, the first and second, and the third coales- 

 cing near their middle respectively with each other, and the first with the 

 costal, ending on the costa before the apex ; discocellulars concave, upper radial 

 from a slight angle close to subcostal, the lower radial from above the 

 middle ; median veinlets emitted at equal distances apart and from the base, the 

 lower median terminating at the posterior angle ; submedian vein sinuous, being 

 much recurved downward from the base, and touching the posterior margin at one- 

 fourth from the base from whence it is curved upward, and terminates on the 

 posterior margin. About one-fourth from the posterior angle, the middle of the 

 posterior margin being folded beneath the wing as above stated. Eindiving broad, 

 quadrate, tailed ; anterior margin very much arched, and almost angled in its middle, 

 apex angled, exterior margin broadly produced in the middle, and with a prolonged 

 tail at end of the upper median veinlet, anal angle rounded ; costal vein short and 

 terminating on the middle of the margin ; first subcostal branch ending beyond the 

 middle, and the second at the apex ; cell narrow ; discocellular starting from near 

 the base of lower subcostal, and running in the same straight line, then curving 

 obhquely downward and outward to lower end of the cell, radial from its middle ; 

 the middle median veinlet emitted at a short distance before end of the cell, lower 

 median at about two- fifths ; submedian and internal vein slightly recurved, the 

 suhnedian furnished ivlth a prominent black sagittate glandular jnitch, divided by the 

 vein, near the anal angle ; the patch clothed with black elongated scales of nearly 

 equal width throughout, their apex being very obtusely bidentate, and their base also 

 bidentate ; some few of these scales are much narrower, but of the same form. Bodi/, 

 slender ; palpi very compactly clothed with short hairy scales, tip pointed ; legs
