while in Acidalia the origin of the second subcostal is usually very remote 

 from the first subcostal; the median venules are shorter than in Acidalia. 

 Legs very long and slender; hinder pair slender, the tibiae not swollen, but 

 long and slender, with two pajrs of large, long spines ; tarsi two-thirds as long 

 as the tibia 1 . Male abdomen very long and slender. Coloration: wings thin, 

 glossy gray, with pale-yellowish costal spots, with two much-curved, sinuate, 

 faint lines. 



This genus is remarkable for the extremely long palpi, while the fore 

 wings are much arched on the costa, and the angle of the hind wings is large 

 and prominent. The venation differs chiefly from Acidalia in there being two 

 subcostal cells. 



Ceratodalia gueneata, sp. nuv. Plate 10, fig. 40. 



8 6. — Body and wings ash-gray, with a silky luster. Head brown in 

 front; orbits much paler. Tore wings with eight or nine pale-ochreous, 

 irregular, costal spots, with about six indistinct lines, which are parallel and 

 bent outward below the costal region nearly at right angles ; the four inner 

 lines are dark and indistinct; the fifth line is a continuation of one of the 

 yellow costal spots ; just below the costa, it is curved inward, and then makes 

 a rectangular bend outward, and thence goes obliquely to the outer third of' 

 the inner edge, curving in a little on or just below the third median vein ; a 

 submarginal scalloped light line; a fine blackish marginal line on both wings; 

 fringe pale gray, spotted with blackish. Hind wings with two much-curved 

 pale shades, the cuter bent at right angles and parallel with the outer edge 

 of the wing. Beneath, highly colored ; basal two-thirds of wing dark brown, 

 mottled with light dots near the costa ; a dark discal linear dot ; half-way 

 between the dot and the outer edge of the dark-brown area a dusky line, 

 bent at right angles opposite the dot. The brown area is limited by a repro- 

 duction, very distinct, of the whitish line, which makes an acute rectangular 

 bend opposite the discal dot, the angle being situated half-way between the 

 discal dot and the apex of the wing. Beyond this line, the wing is much 

 lighter, mottled, with white, with deep-ochreous slashes, the veins deep 

 ochreous, and the fringe as above. Hind wings with the same markings as 

 above. Legs brown, ringed and spotted with whitish. 



Length of body, <?, 0.45; of fore wing, 9, 0.55; expanse of wings, 

 1.05 inches.
