H. Subcosta and radius of hind wings fused nearly 

 to end of the discal cell (Fig. 553). 



I. Small black moths. 



(Smoky-moths.) PYROMORPHID^E (part). 



II. With long, curling, light-colored or brown 

 woolly hairs 



(Flannel-moths.) MEGALOPYGID^:. 

 HH. Subcosta and radius of hind wings distinct 

 or only slightly fused. 



I. Anal veins of fore wings anastomosing so 

 as to appear as a branched vein (Fig. 552). 



(Bag-worm moths.) PSYCHID^E. 



II. Anal veins not anastomosing. 



J. Vein m t of fore wings arising from the 

 discal cell nearly midway between 

 veins m l and m 3 (Fig. 603). 



(Silkworm-moths.) BOMBYCID.E. 

 J J. Vein m- 2 of fore wings arising from the 

 disced cell nearer to radius than to cu- 

 bitus, so that cubitus appears three- 

 branched (Fig. 589). 



(Oak-worm moths.) DIOPTID^E. 



J J J. Vein m 2 of fore wings rising from discal 



cell nearer to cubitus than to radius, so 



that cubitus appears four-branched (Fig. 



548). (Carpenter-moths.) COSSID^E. 



EE. Hind wings with less than three anal veins. 



F. Fore wings with two distinct anal veins or with these two 

 veins j>artly fused so as to appear like a single branched vein. 

 G. The two anal veins distinct (Fig. 553). 



PYROMORPHID^E (part). 



GG. The two anal veins partly fused and appearing like 

 a single branched vein (Fig. 552). PSYCHID.E (part). 

 FF. Fore wings with but one complete anal vein (rudiments of 

 one or two others sometimes present). 

 G. Frenulum present. 



H. Hind wings with subcosta and radius 

 apparently distinct, but connected by a strong 

 oblique cross-vein; moths mostly with narrow, 

 long, strong front wings and small hind wings. 

 (Sphinx- or hawk-moths.) SPHINGID^E. 

 HH. Hind wings with subcosta and radius either 

 distinct or fused, but not connected by an 

 oblique cross-vein. 



I. Vein m 2 of fore wings closer to radius than 

 cubitus, cubitus being apparently three- 

 branched. 



J. Subcosta of hind wings extending 

 from base to apex of wing in a regular 

 curve (Fig. 560); moths with heavy 

 abdomen and rather narrow strong 

 fore wings. 



(The prominents.) N OTODONTID^E.
