e". Nervure 8 of f.-w. arises behind apex of cell, out of 

 stalk of 6 and 7. Wing-margin entire. Nervures 4 

 and 5 of h.-w. stalked, 3 free, out of hinder angle. 9 

 of f-w. to outer margin, 10 to apex. Eyes naked. 



d'. 4 and 5 of f.-w. with long stalk out of the hinder 

 angle, 3 arising just before the hinder angle. . 



d". 4 and 5 of f.-w. separate from hinder angle, 3 origina- 

 ting a long way before the hinder angle. 



e'. Palpi protruding or descending. Front tibiae without 

 " Schienenblatt." Outer margin of f.-w. longer than 

 hind margin 



e". Palpi ascending. Front tibiae with large " Schienen- 

 blatt." Outer margin of f.-w. scarcely so long as 

 hind-margin 



b". The basal cell of h.-w. large and broad, as broad as or 

 broader than the middle cell and often but little 

 shorter, terminated by a long transverse nervule. 



c'. The wing-margin and fringes entire. 



d'. 6 and 7 of the f.-w. free, out of the front angle. 8 of 

 f.-w. into hind margin, 9 into apex 



d". 6 and 7 of f.-w. long-stalked; 9 of f.-w. into outer 

 margin, 10 into apex 



c" . Margin of wing and fringes wavy or dentate, 6 and 7 

 of f.-w. stalked, 8 out of front angle. 



d'. 9 of the f.-w. into the apex, 8 of h.-w. connected by 

 transverse nervule with 7, and gives off behind the 

 basal cell no supplementary branch towards costa. 



e'. Costa of h.-w. not emarginate. Stalk of 9 and 10 of 

 f.-w. shorter than the free part of nervure. 



/'. Costa of h.-w. strongly arched. Palpi very long, with 

 long cylindrical terminal joint. . 



/". Costa of h.-w. straight, palpi short, with small, 

 knobbed terminal joint 



e". Costa of h.-w. before the extremity of nervure 8 deeply ^ 

 emarginate. Stalk of 9 and 10 much longer than [ r 

 the free part thereof . . . . . . . . . . j 



d". 9 of f.-w. into the outer margin, 8 of h.-w. connected i 

 by transverse nervule with front median, and sends ' 

 out behind the extremity of the basal cell a branch [ 

 towards costa . . . . . . . . . . . . j 



The full-grown Larva. 



B. Body without (well-developed) warts, or only with 2 dorsal 

 and some very few small lateral ones on each segment. 

 a. All segments similarly haired (and marked). Sides 

 always without " lateral streaks " [see infra at b*] . 



* All the hairs rather uniformly distributed over the sur- 



face of the body, without forming groups or areas of 



densely crowded hairs. 

 a'. Body cylindrical. 

 V . No warts; head blue-grey ; body marked with gaily 



coloured longitudinal lines 

 V ' . Segments 4-11 each with two rather large dorsal warts ; 



head black ; body without longitudinal lines 

 a". Body somewhat flattened, without dorsal warts; the 



first three segments with rather large, foot-like lateral 



protuberance 



* * Some hairs (different in colour and length from the rest) 



form distinct groups or clothe particular areas. 

 a'. Each segment on the dorsum with two small groups ) 



or tufts of short stiff (red or yellowish-red) hairs . . j ( 



a". The whole dorsum between the larger hairs clothed 



with shorter, closely-crowded more or less appressed
