above to the inside of the upper surface of the body, and below to the 
coxae and the interior of the sternum : these serve to raise the wings. 
Only two muscles are attached above to the wings by tendons. The 
axis of rotation of the wings runs parallel to the axis of the body.

The author compares the development of the egg of Bombyx mori, 
A ttacus mylitta , and Saturnia pyri. At the end of winter, the constitu- 
ents of the egg are as follows: — (1) A solid shell, to which an opaque 
layer, a kind of curd, adheres internally ; (2) a very transparent substance, 
regarded by some as a secretion of the blastoderm ; (3) serous involu- 
crum, membrane composed of large flat polygonal, pigmented, and nucle- 
ated cells ; (4) nutritive yelk, broken into large spheres containing one 
or more protoplasmic nuclei ; (5) germinative pellicle, with the ventral 
surface turned outwardly, aud containing the amnios. This last re- 
sembles the membrane of the serous involucrum, but the cells are without 
pigment.

The following arrangement of Macrolepidoptera is suggested : — Noctu - 
ina, Bombycina , Geomelrina , Rhopalocera , Sphingina. Hepialus , Coleo- 
pliora , and the Psychidce are considered to be archaic forms.
