oval reddish -warts behind^ whence spring long yellow 

 hairs ; and two smaller ones^ scarcely reddish and more 

 rounded, in front, placed close together. Prothorax 

 thickly clothed with long golden-yellow hairs: meso- 

 and meta-thorax deep black, almost hairless. Anterior 

 •wings elongate, narrow ; smoky blackish, thinly clothed 

 with short yellow hairs, and with longer ones on the 

 cubital veins ; a large milky- white spot at the thyridium 

 and a much smaller one at the arculus; veins strong, 

 deep blackish fuscous ; discoidal cell very long ; first 

 apical cellule much longer than the third, its base extend- 

 ing somewhat along the upper edge of the discoidal; 

 the second short, straight at the base ; third longer than 

 the second, nearly rounded at the base, but with a short 

 angle, the dot near its base (common to many Trichop- 

 tera) black ; fourth as long as the third, obliquely trun- 

 cate ; fifth nearly as long as the first, somewhat acute : 

 posterior wings pale smoky, somewhat iridescent ; the 

 pouch in the $ rather long, the hairs on the veins 

 forming it erect, very long, grayish yellow ; finnges short 

 and grayish, long at the anal portion. Legs with black 

 cox^ and femora, and grayish-ochreous tibice and tarsi, 

 and black spines ; coxae deeply and broadly sulcate be- 

 neath, with a row of yellow hairs on each side of the

 dish at the posterior margin above, the margins of the 

 succeeding segments grayish. 



Anal appendices of the ^ : the last abdominal segment 

 above bears in its middle an intensely black, scabrous, 

 spade-shaped plate, flattened and slightly depressed, ex- 

 tending almost to the base of the segment, its apex broadly 

 rounded, and rather wider than the base ; on each side 

 of this plate is a deep, elongate, and ochreous cavity ; 

 the margin of the segment is regularly concave, the 

 plate not extending beyond it; app. inf. long and finger- 

 shaped, nearly cylindrical, dilated at the base, ochreous, 

 with long black hairs at the apex ; app. intermed. in- 

 tensely black, broad, and triangular, lying so close toge- 

 ther as to appear as one piece, their bases extending 

 downwards, and diverging, forming carinate projections 

 on the pai-t whence they arise, at the beginning of each 

 of which is a rounded reddish tubercle ; app. inf. not 

 longer than the app. sup., ochreous, strong, sub-acute, 

 diverging, fringed with long hairs, furnished near the 

 base with a projecting wing-like lobe, which parts form
