which also coalesce (Fig. 438). p. 357. 



LACOSOMIDiE. 



MM. Veins III,. Ills, III*, and III 5 united 

 at base (Fig. 419). p. 340. .BoMBYCiD^E. 

 KK. Vein V a of the fore wings emerging from 

 the discal cell nearer to cubitus than to radius, 

 causing cubitus to appear four-branched. 

 L. Fore wings with an accessory cell (Fig. 255) 

 veins Ilia and Ills coalesced at base, also 

 ve : ns III* and Ills; the accessory cell is 

 formed by the anastomosing of veins Ills 



and Ilh + s. p. 221 CossiD^E. 



LL. Fore wings without an accessory cell; 

 veins III 3 and III* coalescing to a greater 

 extent than any other branches of radius 



(Fig. 26 1 ,. p. 223 ... EUCLEID^E. 



FF. Hind wings with less than three anal veins. 

 G. Fore wings with two distinct anal veins or with the 

 anal veins partially grown together in such a way as 

 to appear as a single branched vein. 

 H. Anal veins of fore wings partially grown together 

 so as to appear as a branched vein (Fig. 253). p. 219 



PSYCHID^E. 



HH. Fore wings with two distinct anal veins, p. 226. 



PYROMORPHID/E. 



GG. Fore wings with a single fully preserved anal vein. 

 This is the second anal vein (vein IX) ; the first anal 

 vein (vein VIII) is absent or represented merely by a 

 fold; and the third anal vein (vein XI) is short, not 

 reaching to the margin of the wing, or is wanting; 

 usually when the third anal vein is present it is joined 

 to the second anal vein, so that the latter appears to 

 be forked towards the base. 



H. Frenulum present. In most cases the humeral 

 angle of the hind wings is not largely expanded. 

 I. The five branches of radius and the three branches 

 of media of the fore wings present, and each one 

 arising from the discal cell (Fig. 404). Small 

 nioths (the largest expanding only three fourths 

 inch) resembling Hawk-moths in form, and with 

 translucent spots on their wings, p. 328.
