2(52 [October, 



Fore-wings elongate, dilated outwards, costa almost straight, apical margin with 

 a conspicuous notch immediately below the apex, which is depressed, attenuated and 

 falcate ; below the notch the margin of the wing is obtusely angulated, thence 

 obliquely and slightly convex in the direction of the anal angle. Neuration, 11 

 veins ; 5 apparently wanting ; 8 and 9 from a common stem, 8 following the curve 

 of the falcate apex ; rest separate. 



Hind-ioings 3-lobed, the first fissure reaching to about one-third from the apex, 

 the second fissure to within one-fourth of the base, without teeth or tufts of scales. 

 Neuration, 8 veins ; all separate. 



Abdomen somewhat tufted at the sides ; lateral claspers of ordinary length. 



Legs, first and second pairs somewhat thickened at the joints; posterior pair 

 with very short spurs, in the first pair having the inner spur longer than the outer, 

 in the second pair both spurs are of equal length, a few long scales project over the 

 joint above them. 



This genus agrees with Utuca in neuration, but differs in the 

 more thickly clothed palpi, and in the more distinctly falcate apex of 

 the fore-wings, of which the very short fissure is placed decidedly 

 higher than in that genus. 



Uroloba fuscicostata, sp. nov. 



Antennee brownish-fuscous. 



Head, thorax, Siud pal J) i, very pale fawn colour, much shaded and sprinkled with 

 reddish-brown. 



Fore-wings pale fawn colour, much sprinkled with reddish-brown and brownish- 

 fuscous scales, the latter predominating below the middle of the costa, at the base 

 below the fold and along the extreme costal margin ; cilia tinged with brownish- 

 fuscous, especially about the anal angle. Under-side with the costal margin broadly 

 streaked with black, reacliing from the base to that point where the margin begins 

 to be depressed towards the apex, the widest part of this band of black scales being 

 about the middle of the wing. Exp. alar., 22 mm. 



Hind-wings pale fawn, sprinkled with pale brownish scales ; cilia very pale fawn, 

 brownish-fuscous at their bases around each of the lobes. Under-side with a line of 

 deep black scales reaching along the costa as far as the base of the first fissure, there 

 are also a few blackish scales beneath the cilia, helping to give them that fuscous 

 appearance which is visible on the upper-side. 



Abdomen fawn colour, dusted with brownish-fuscous, the scales on the sides of 

 the posterior segments project laterally. 



Legs whitish fawn colour, sprinkled with brown scales, especially at the joints.

This species is represented in my collection by two specimens, 

 both males, collected at Valparaiso for which I am indebted to Mr.
