Drepanidse. As in the Drepanidre vein VII appears to be 
four-branched, and the 
course of vein II of the 
hind wings is similar in 
the two families, except 
that in the Auzatidae this 
vein anastomoses with 
vein III beyond the discal 
cell; but the extent of 
this anastomosis varies 
greatly in different indi¬ 
viduals of our species. 
In the Auzatidae the 
apex of the fore wings 
is not sickle-shaped ; and 
the branches of radius of 
the fore wings coalesce 
as in the Geometridae,

Family Drepaniixe (Dre-pan'i-dae). 
The Hook-tip Moths . 
The members of this family are small, slender-bodied 
moths, which can be easily recognized by the sickle-shaped 
apex of the front wings (Fig. 345). An 
approach to this form of wing is pre¬ 
sented by some species of the Satur- 
niidae and by certain Geometrids. But 
the former are large, stout-bodied moths ;

* In the Drepanidse veins IlU-j-s and Ilb-M do not coalesce from the 
apex of the discal cell outward (Figs. 346 and 347); but veins 111 3 and III 4 
anastomose for a greater or less distance near the apex of the wing, thus 
forming an accessory cell.
