which also coalesce (Fig. 438). p. 357. 
LaCOSOMIDvE. 
MM. Veins Ilia, Ills, III«, and III 6 united 
at base (Fig. 419). p. 340.. Bombycide. 
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 Ilia coalesced at base, also 
veins III4 and Ilia; the accessory cell is 
formed by the anastomosing of veins III* 
and III4 + B. p. 221. Cosside. 
LL. Fore wings without an accessory cell; 
veins 111 3 and III 4 coalescing to a greater 
extent than any other branches of radius 
(Fig. 261 ; . p. 223.. Eucleide. 
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 
Psychide. 
HH. Fore wings with two distinct anal veins, p. 226. 
PYROMORPHIDE. 
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 thb 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 
moths (the largest expanding only three fourths 
inch) resembling Hawk-moths in form, and with 
translucent spots on their wings, p. 328.
