Imago (52:1). Head moderately large, pretty uniformly tufted witli rather long 

 hairs ; front not very full, protuberant, but not greatly, in the middle beneath, nar- 

 roAver than the eyes, a very little higher than broad, the upper posterior edge very 

 slightly convex in the middle, the lower edge a little abrupt, broadly rounded; vertex 

 small, slightly tumid, moderately long, not broad, a minute tubercle in the middle of 

 either side, and a median ridge posteriorly, taking its rise anteriorly from a short trans- 

 verse carina at the posterior limit of the swollen portion; anterior edge nearly straight, 

 posterior convex; upper border of the eye scarcely angulated opposite the middle of 

 the base of the antennae. Eyes pretty large, not very full, pilose, with short, very 

 delicate, not very frequent hairs. Antennae inserted in the middle or possibly just be- 

 hind it, in a broad, deep pit, disconnecting the front and vertex, their bases crowded 

 together and separated scarcely any, if at all, from the edge of the flanks; scarcely 

 longer than the abdomen, consisting of thirty-four or thirty-five joints, increasing iu 

 size a little and quite gradually on the apical fourth of the antennae, the last 

 two or three joints diminishing again, and terminating in a bluntly rounded point; 

 transversely circular, the club a little depressed and distinctly carinate beneath. Palpi 

 slender, barely twice the length of the eye, compressed, the apical joint about one- 

 third the length of the penultimate ; excepting the apical joint, provided beneath with 

 a tuft of pretty long hairs, compacted in a vertical plane. 



Prothoracic lobes similar to those of Euodia, minute, expanding upward from the 

 base rather rapidly into a somewhat reniform, bulbous mass when xdewed from the 

 front, of nearly equal height throughout, the ends well rounded, the exterior extrem- 

 ity tapering slightly, equally long on the summit, half as long as high, and about three 

 times as broad as high. Patagia very slightly convex, the posterior lobe nearly three 

 times as long as broad, tapering rapidly, the extremity produced nearly as far again, 

 as a uniform finger with a bluntly rounded apex. 



Fore Avings (38:4) but little produced at the apex; costal border regularly but very 

 slightly convex; outer border the same, the upper outer angle being pretty well 

 marked: inner border straight, the lower outer angle scarcely rounded ofi". Costal 

 nervure as iuEnodia; first two superior bi'anches of the subcostal nervure arising 

 close to the tip of the cell, the latter scarcely less than half as long as the wing and 

 twice and a half longer than broad; median and submedian nervures not enlarged at 

 the base. 



Hind wings with the costal border regularly though not greatly convex ; outer bor- 

 der regularly and considerably convex, excepting a slight excision at the lower subcos- 

 tal interspace ; inner border slightly convex, both of the outer angles broadly and 

 equally rounded ofl'. Veinlet closing the cell striking the median nervure a little be- 

 fore its last divarication, and the subcostal at the termination of the short basal curve 

 of its final branch. First median nervule originating a very little further from the 

 base of the wings than the origin of the second subcostal nervule. No androconia. 



Fore legs very small, cylindrical, the tibiae one-third the length of the hind tibiae; 

 tarsi scarcel}' shoi'ter, consisting either of five joints, of which the first is twice as 

 long as the others together, and they diminishing regularly in length, the apical one
