NATHAN BANKS. 239 



Rhyacophylax varius n. sp. — Brownish ; vertex black, antennae 

 whitish, palpi dark beyond basal joints ; thorax black, legs yellowish, 

 femora and tips of tibia blackish, wings brown, black on tips, and a 

 large black spot in middle, before it is an area with pale greenish scale- 

 like hairs, and beyond it are two incomplete bands, the costal parts 

 of the bands broader and white, the rest greenish, the outer band 

 broader than the inner band ; apical fringe mostly white. Expanse 14 

 mm. 



Type. — cJ". From Turricares, Costa Rica. 



Syiuphitopsyche plutoiiis n. sp. — Deep dull black ; antennae 

 and legs brownish-yellow. Head with short golden hairs, more dense 

 on the pronotum, the short hair of the wings, in some lights, shows 

 yellowish. Eyes rather small, head strongly convex above eyes, each 

 side on vertex is a large subtriangular wart ; antennae faintly ringed, 

 the joints moderately long ; second joint of palpus longer than third 

 or fourth, which are subequal, and convex below, fifth longer than 

 third and fourth together. Pronotum rather large, with a large wart 

 each side near middle, and a smaller one each lateral side. Venation 

 nearly as in S. maiiretanica McLach. as figured by Ulmer ; in hind- 

 wings the subcosta and radius very plainly unite before tip, in the fore- 

 wings the subcosta runs into the margin, but before its tip it is very 

 close to the radius, and in some lights appears to run into radius. The 

 discal cell is a trifle shorter than in S. mauretatiica, in fore-wings the 

 connecting veinlet from cubitus to anal is much farther out and more 

 oblique, and in hind-wings the second fork does not reach back to the 

 cross-vein beneath discal cell, and the cross-vein is transverse, not 

 oblique ; in hind-wing the radial sector may be connected to median, 

 but the vein here is very indistinct. Expanse 13 to 15 mm. 



Type. — cf. From mountains near Harrar, Abyssinia 

 (Kristensen). 



Dipseiirtopsis Imddhan. sp. — Reddish or yellowish-brown, ver- 

 tex, mesonotum, and dorsum of abdomen, blackish, tips of antennal 

 joints dark; wings brown or dark yellowish-brown, with sparse golden 

 hair, stigma pale, and pale spots in bases of second and fourth apical 

 cells and just before base of median cell, and also just below fork four ; 

 hind-wings a uniform brown; legs yellowish-brown. In fore-wings 

 forks 1 and 3 are each a little shorter than their pedicels, forks 2 and 

 4 each reaching to anastomosis. The modified spur of hind tibia of 

 male as figured ; the short process strongly curved, but without teeth 

 on edge, the long process furcate toward tip. Expanse 25 mm. 



Type. — d^. From Chapra, Bengal, India (Mackenzie), 

 and Pusa, India, 23d August. In shape of the spur related 

 to D. indicus McLach., but the processes are shorter, and the 

 short one without teeth.
