lliiul ■wins,'!* with the costal miii'iiin nillici- lull :iinl convex, a little straightened in 

 the middle, curviiiic haokward roundly at the tip, joiiiiiii; tlie curve of the outer mar- 

 gin, whicli is a little full at the middle subcostal nervule, especially in tlie $ , but 

 beyond that pretty reirularly and broadly rounded, more or less obscurely angulateil 

 at the lower median nervule, where there is always a long and slender thread-like tail, 

 longer than the width of an interspace at its base ; there is also a secondary very 

 slight projection at the tip of the middle median nervule; the inner margin is rather 

 broadly convex, more strongly next the base, and just before the tip angularly, 

 though but little, emarginate. Submedian nervui-e terminating on the outer border, 

 just by the anal angle; internal nervure terminating beyond the middle of the inner 

 margin. 



Androconia slender, sublanceolate, about I'our times as long as broad, subequal but 

 tapering slightly on apical half, the apex broadly rounded, the stalk very long. 



Fore tibiae about three-quarters the length of the hind tibiae, the fore legs similarly 

 developed in the two sexes, excepting at the terminal tarsal joint, and with the same 

 exception and the nakedness of the tibial spurs, resembling the other legs very 

 closely ; fore tarsi but little shorter than the tibiae, the last tarsal joint either 

 developed as in the other legs (?) ; or very small, similar to the preceding joints 

 bearing at its unenlarged extremity simply a pair of slightly curved spines, dif- 

 fering in no respect Trom the others behind and having Its upper surface thickly 

 covered with extremely short hairs (J). All the femora of the male (and male 

 only) heavily fringed beneath with long hairs. Middle tibiae more than sis-sevenths 

 the length of the hind pair, armed beneath with a very few short and slender spines, 

 and at tip with rather long, tapering, scaly spurs. First joint of tarsi more than 

 equalling the rest taken together, the others nearly equal, all furnished beneath on 

 either side with a clustered mass or row of small, not very slender, crowded spines, 

 a single one on either side of the apex of each joint being longer, spur-like. Claws 

 small, strongly compressed, tapering to a fine point, strongly curved or bent before 

 the middle, with a small, basal, triangular, laminate tooth beneath ; paronychia simple, 

 slender, nearly equal, curving a little in tlie opposite direction to the hook, than which 

 it is a little shorter; pulvillus very minute, thrust forward, nearly circular. 



Male abdominal appendages : upper organ with such broad alations as to leave in the 

 middle behind a broad, deep notch, the bottom of which is squarely cut; the alations 

 tumid, well rounded, of about equal length and breadth; lateral amis very long, 

 slender, tapering, finely pointed, strongly recurved and wholly concealed next the 

 inner surface of the alations; clasps about as long as the upper organ, straight and 

 rather slender, a little gibbous on the basal half, beyond tapering, but very bluntly 

 pointed. 



Egg. Depressed echinoid-shaped, as broad at base as at summit, a little depressed 

 and Infnndibuliform at the middle of the summit, covered everywhere with greatly 

 and abruptly elevated prominences, connected with all about them by heavy well- 

 defined ridges, scarcely disposed In rows, leaving between the ridges deep hollows 

 with abrupt sides, above becoming sm.aller and confused, the openings between the 

 ridges assuming more the form of pits on an otherwise uniform surface. Micropyle 

 sunken in a not very deep pit, obscure, consisting of a few rather large, oval cells 

 around a minute, central, circular cell, and surrounded by a very few roundish cells of 

 about the same size, their walls faint, but not very delicate. 



Caterpillar at birth. Body of nearly equal diameter throughout. The last com- 

 pound segment tapering and rounded at the tip, flattened on the dorsal area np to the 

 laterodorsal line; below this sloping to the somewhat laterally produced infrastig- 

 matal margin. Laterodorsal series of hairs consisting, upon the abdomen, of larger, 

 centrally situated, curving hairs, about as long as two segments, and outside and a 

 little posterior to them similar, but shorter and more recumbent, backward directed 

 hairs, one of each to a segment in each row. The hairs below the spiracles con- 

 sist of three on each side, on each segment, one very long, central one, and two 

 shorter, anteriorly placed, the upper the longer. Midway between the laterodorsal,
