course of vein II of the

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 ;

 apex of the discal cell outward (Figs. 346 and 347); but veins IIIj and II I 4 

 anastomose for a greater or less distance near the apex of the wing, thus 

 forming an accessory cell.
