 iK'i'vuh; t'liiitted a little beyond the middle of the outer t\vo-lil'ths of the u|)i>er margin 

 of the cell; second, half way between tiie orinin of ilic liisl and the tip of the cell; 

 third, at about the same distance before, as the l)asi; of ihe fourth is beyond, a point 

 midway between the tip of the upper margin of tlie cell and the apex of the wing; 

 second inferior subcostal ncrvnle arising but a very siiort distance down tiie cell; the 

 latter two-tlfths the length of the wing and scarcely three times as long as broad. 

 Last median nervulc connected l)efore the middle of its basal curve with tlie vein 

 closing the cell. 



Hind wings witii the costal bordei- pretty strongly archeil at the very base. l)eyond 

 nearly straight, a little l)owcd. the outer margin well rounded, scarcely less so in the 

 middle half, slightly crenulate. the apex well rounded; the inner t)order enlarging at 

 the base, beyond, to a siiort distance past the middle of the wing, straigiit, then 

 roundly excised and contiiniing parallel to its previous course, the outer angle routuled. 

 Precostal nervure originating at a little distance beyond the divarication of the costal 

 and subcostal, nearly straight, forked at the tip, the largest fork directed outward; 

 cell closed. 



Forelegs small, cylindrical, the tibiae about one-iialf the lengtii of the liiiid til)iae; 

 tai'si three-tifths tlie length of the tibiae, both very profusely covered with long hairs 

 spreading in a lateral plane, giving the whole leg a greatly appressed and featiiery ap- 

 pearance, more consi)icuous in the male than in the female; the tarsi consist of five 

 joints of Avliich the basal is twice (?) or thrice ( J ) as h)ng as the others combined, and 

 tiiey equal in length among themselves; the terminal joint bluntly rounded and either 

 unarmed ((J), or all armed at the tip beneath with a pair of very delicate and slender, 

 minute spines, those of the terminal joint being apical (?). Middle tibiae slightly 

 longer than the hind pair; both furnished on either side of the low^er surface and on 

 the upper edge of the inner side with roAvs of frequent, pretty long and very slender 

 spines, those of the latter row less frequent on the hind tlian on the middle tibiae ; 

 spurs very long and very slender. The second and fifth joints of tarsi about equal, 

 file third slightly longer than the fourth, which is the smallest; first nearly as long as 

 all the others together; all provided beneath on all the joints with four rows of 

 crowded spines, similar to those of the tibiae, the apical ones of each joint a little 

 stouter. Claws moderately delicate, very strongly curved, a little compressed, finely 

 pointed. Paronychia about as long as the claws, slender, tapering, finely pointed, a 

 little curved ; pulvillus very small indeed, quadrate. 



Abdomen compressed subfusiform, the upper organ of the male appendages mod- 

 erately stout, the hook as long as the body, very stout, depressed, nearly straight, 

 tapering, but very bluntly pointed; inferior arms pi'etty stout, bent toAvard each other 

 in their basal half, beyond directed backwards horizontally side by side to about 

 the centre of the clasp, or as long as the hook. Clasps subquadrate, a little longer than 

 broad, the upper posterior angle slightly produced and incurved, the inferior border 

 pretty regularly arcuate; interior finger tapering, nearly following the inferior border 

 of the clasp, strongly arcuate or sinuate toward the tip and linely pointed; a secondary 

 armature is foiuid in the centre of the inside of the clasp. 



Egg. ^'ery short ovate, transversely circular, broad and roumled at the base, 

 tapering a little to a broadly rounded apex, the diminution in size less apparent because 

 furnished with a few very prominent, greatly compressed, longitudinal, regular and 

 equidistant ribs, which increase in height toAvard the summit, where they terminate 

 al)ruptly with a very high well rounded outline; surface between the ribs smooth, 

 lu'oken up V>y numerous delicate transverse lines. ]Micropyle composed of a few, com- 

 paratively large, jjretty uniform, roundish cells arranged in a rosette. 



Caterpillar at birth. Head smooth, the upper two-thirds nearly equal, 

 broadest a very little above the middle, a little higher than broad, furnished with 

 very few scattered long hairs, the hemispheres a little elevated and i-ounded at 

 summit. Body neai-ly or iiuite uniform, armed with longitudinal rows of lit-
