LEPIDOPTERA HETEROCERA. 1549 
Hepialide, Steph. Ill. Brit. Ent. Haust. ii. 3. Newman, Ent. 
Mag. i. 67. 
Zeuzeridi, p., Boisd. 
The wing-veins of the Hepialide are very different from those 
of the other Bombycites in structure. The discal areolet is as it 
were doubled; the second inferior vein is about ten times further 
from the third than from the first; the third is joined to the discal 
areolet_ by an oblique veinlet, and to the submedian vein by two 
veinlets, whose junction forms an acute angle, which emits a vein 
to the border.
