mago (55:7). Head sninll, densely covered -witli seales.^vhicli form a tuft heliind 

 the .inteniiae; proviiled also sparsely on the upper half of the front witli sliort, curv- 

 ing, erect hairs. Front flat, very slightly tumid beneath, scarcely surpassing the front 

 of the eyes; above hollowed in the middle, with a broad longitudinal gi-oove; 

 scarcely half as high again as broad, fully as broad as the eyes; the sides parallel, 

 the upper border squarely excised, its angles rather largely hollowed in front of the 

 antennae; lower border strongly rounded. Vertex not tumid, well rounded longitu- 

 dinally, rather suddenly and broadly elevated behind the antennae, as their support; 

 separated from the occiput by a not very distinct, because tortuous, broad and not 

 very deep transverse channel, the sides of which, about equally abrupt, form a right 

 angle with each other; occiput longitudinally excised iu the middle. Eyes not very 

 large nor full, entirely naked. -Vntennae inserted rather in advance of the middle of 

 the summit, separated by a space barely equalling the diameter of the first joint, 

 scarcely longer than the abdomen, composed of about thirty-two joints, of which the 

 last twelve or thirteen form the club, which is nearly three times broader than the 

 stalk, four or five times longer than broad, very gradually increasing in diameter, the 

 last two joints forming the bluntly rounded tip. Palpi slender, compressed, nearly, 

 if not quite, twice as long as the eye, the terminal joint very slender, scarcely more 

 than one-third as long as the iniddle joint and clothed only with recumbent scales; 

 other joints heavily scaled and also thinly fringed with rallur long, forward reaching, 

 erect, coarse hairs, narrowly compressed in a vertical plane. 



Patagia scarcely tumid, a little arched, slender, about two and a half times longer 

 than broad, the inner border considerably curved, the outer bent, tapering considera- 

 bly, bnt the apical two-fifths equal, moderately slender, bent a very little outward and 

 bluntly ronnded at tip. 



Fore wings (39: 18) fully three-fourths as longagain as broad, the costal margin 

 strongly and rather abruptly convex at base, beyond nearly straight, scarcely convex, 

 the extreme tip sloping downward; outer margin rather strongly and regularly con- 

 Tex, its general direction at an angle of about 55'^ with the middle of the costal 

 border, the upper angle abrupt but rounded, the lower well rounded off, inner margin 

 straight. Costal nervure terminating a little before the tip of the cell; subcostal 

 •with three superior branches; first arising a little beyond the middle of the cell, 

 second at nearly one-third the distance from this to the apex of the cell, the third as 

 In Nomiades, but forking before the middle of its course; veins closing the cell 

 excessively feeble throughout, bent at a slight angle; cell somewhat more than half 

 as long as the wing, and fully four times as long as broad. 



Hind wings with the costal margin a little convex on the basal third, beyond 

 scarcely convex, the outer margin well ronnded, fullest in the anterior half and 

 especially in the $ , the inner border a little convex, the apical half slightly excised, 

 the angle very broad, ronnded off. Submcdian nervure terminating at the anal angle ; 

 Internal nervure terminating a little beyond the middle of the inner border. 



Androconia flattened, oval in shape, almost alike at the two ends, the pedicel 

 scarcely tapering.
