Imago (56 : C). Head moderately large, furnished with long delicate hairs of nearly 

 equal length in front and above. Front tumid, particularly in the middle (where it is 

 minutely tuljerculatc), considerably and rather generally surpassing the front of the 

 eyes, above descending considerably to the antennal pits and continuing nearly on a 

 level to the expanding termination behind the antennae where there is a delicate trans- 

 verse ridge ; the portion in front of the antennae is half as broad again as high and as 

 broad as the eyes on a front view, the sides scarcely diverging; lower border squarely 

 docked. Vertex somewhat depressed above, tumid behind, only in the latter part 

 surpassing the level of the eye, the anterior outer angles raised somewhat and a very 

 little produced ; anterior liorder scarcely concave, scarcely raised, the slight ridge 

 abrupt. Eyes rather large and full, naked. Antennae with the posterior base in ad- 

 vance of the middle of the summit, inserted in distinct, moderately deep pits, separated 

 from each other by the width of the second antennal joint; consideral)ly longer than 

 the abdomen, composed of thirty-three or thirty-four joints of which the last seven or 

 eight form a depressed subspatulate club about two and a half times broader than the 

 stalk, three or four times longer than broad, increasing in size very gradually and 

 sliglitly as far as the antepenultimate joint, the last two forming a bluntly rounded 

 tip. I'alpi slender, nearly half as long again as the eye, the terminal joint equalling the 

 middle in length .ind double tlie length of the basal, all clothed thinly with scales and 

 all but the apical furnistied beneath with a rather thick fringe of very long, nearly equal 

 hairs, compressed in a vertical plane. 



Prothoracic lobes obsolete. Patagia very small, broad, with a slender lobe scarcely 

 arching and depressed rather than tumid, composed of a very broadly longitudinally 

 oval basal portion from which projects a tapering, very slender, posterior lobe, two- 

 thirds as long as the basal portion and slightly hooked at the tip, the sides strongly 

 hollowed at the base. 



Fore wings (40: 7) from two-thirds to more than three-fourths as long again as 

 broad, the costal margin gently curved, almost straight in the middle, the apical angle 

 almost rounded oil'; outer border nearly straight or very gently curved, below receding 

 to meet the straight inner border, rounding off the angle. Costal nervure terminating 

 considerably beyond the middle of the costal border; subcostal nervure with three 

 superior branches, the first arising in the middle of the outer two-thirds of the cell, the 

 second a little before the tip of the cell, the third as far beyond as tlie first is before 

 the tip of the cell, branched somewhat before the middle, the upper branch minutely 

 forked at the very tip ; cell three-fifths the length of the wing and fully three and a 

 half times longer than broad. 



Hind wings with the costal border roundly shouldered at the base, beyond very nearly- 

 straight, outer border more or less prominent in the subcostal region, pretty strongly 

 convex, more regularly so In the (J than in the ? , which has the central portion a 

 little less curved; outer lower angle very broadly and regularly rounded, the inner
