humeral angle of the wing (Fig. 567); 



molhs mostly with slender abdomen 



and rather broad delicate fore wings. 



Superfamily Geometrisa. 



II. Vein m^ of fore wings more closely joined 



to cubitus than to radius, so that cubitus 



is apparently four-branched. 



J. Subcosta of liind wings distinct from 



radius, or the two fused for a very 



short distance near the base of the 



wing (Fig. 584). 



K. Bay-flying moths that are black 

 with large whi te or yellow patches 

 on the wings, or with white front 

 wings margined with brown, and 

 having the hind wings pale yellow. 

 (Wood-nymph moths.) Agaristid.*; and Pericopid.e. 

 KK. Not such moths. 



L. Ocelli absent; antenna; pec- 

 tinate. 

 (Tussock-moths.) Lymantriid.e. 

 LL. Ocelli present or, if absent, 

 with simple antenna. 

 (Owlet-moths.) Noctuid.e. 

 JJ. Subcosta of the hind wings fused with 

 radius for one-iifth or more of the 

 length of the discal cell. 

 K. Subcosta and radius of hind wings 

 fused entirely or with only the tips 

 separate (Fig. 591).- .Zyc.enid.s 

 KK. Subcosta and radius of hind winga 

 united for about one-half their 

 length, or more, but usually 

 separating before the apex of the 

 discal eel! (Fig. 597). 

 L. Ocelli present. 



(Tiger-moths.) Arctiid.i:. 



LL. OccUi absent. 



(Footman-moths.) LiTHOSllD.E. 



GG. Frenulum absent; the humeral angle of the hind 



wings largely expanded and serving as a substitute 



for the frenulum (Fig. 6oo)'. 



H. Cubitus of both wings apparently four-branched 

 (Fig. 600). (Tent-caterpillar moths et al.) 



LASICOCAMPID.e. 

 HH. Cubitus of both wings apparently three- 

 branched; robust moths with broad wings (Fig. 

 603). (Giant silkworm -moths.) Saturniina. 



The jugate moths include Inii two families, the Micropter)'gida; and 

 Hepialida?, both represented by but few species and these rarely met with
