emits an anterior lateral nerve, and at 
three-fifths the distance to the second ab- 
dominal ganglion another set appears, as 
well as still another pair just in front 
of the second ganglion, at only the dis- 
tance of the breadth of the ganglion 
from it; an anterior lateral nerve is 
also thrown off from each side of the 
second ganglion, which is 3 mm. distant 
from the first, and another pair on the 
cord midway between the second and 
third ganglia which are 1.9 mm. apart; 
a similar anterior nerve to the third 
ganglion forks when it has passed 
a ganglion’s breadth away. The last 
ganglion is 1.3 mm. distant from the 
third (measured from their centres) and 
emits several nerves; from the outer 
edges of the posterior border a pair of 
stout nerves run parallel to each other ; 
from just behind the middle of the sides 
another pair arises, and nearer them 
than the posterior pair still another— 
all running backward; from the outer 
edges of the anterior border runs another 
pair, which forks almost at origin, one 
branch passing somewhat forward, the 
other somewhat backward. 
Female generative organs. The basal 
stems of the ovarian tubes in the 7-days’ 
chrysalis are 1.25 mm. long and 0.25 
mm. broad; they suddenly diminish in 
size beyond this to about half this diam- 
eter, and then, in a distance of 4 mm., 
course forward and backward three times. 
The portion of the ovarian tubes be- 
tween the oviduct and their own divi- 
sion is 2 mm. long and about twice the 
diameter of the divided tubes. Just 
beneath the anterior extremity of the 
colon, the oviduct expands into a broadly 
oval sac, scarcely longer than broad, 
PSYCHE. 
about 0.65 mm. long, into which opens 
a canal 1.25 mm. long, which expands 
into a subreniform vessel, the sperma- 
theca, 0.8 mm. long and about 0.5 mm. 
broad, terminating at its interior, an- 
terior extremity in a slender curving 
tube about 0.12 mm. in diameter. 
In the 9-days’ (perhaps overlooked in 
the 7-days’) chrysalis, the tips of the 
ovarian tubes are united into a single 
mass for a distance of 2 mm. and extend 
beyond the reduplicated portion, which 
extends over 6 mm. distance; the basal 
stems of these tubes before their union 
are 0.4 mm. in diameter and 2 mm. 
long, uniting on each side of and rather 
above the extremity of the stomach to 
form a single tube, also 2 mm. long and 
no stouter than its branches. 
As the anterior extremity of the 
stomach is overlaid by the reservoir, so 
the posterior end is covered by the 
copulatory pouch, somewhat vase-shaped 
in the anterior portion, the extremity 
of which is inflated, largest in the mid- 
dle and tapering in both directions ; it is 
0.25 mm. long, 1.8 mm. broad in the mid- 
dle, 1.7 mm. at the anterior extremity 
and 1.25 mm. at the constriction; the 
anterior extremity reaches nearly to 
the alimentary reservoir, and is pretty 
strongly constricted before its inflation ; 
just before its hinder extremity, which 
lies beneath the colon, it emits superi- 
orly a tube, which, after some contor- 
tions, curves forward upon the alimentary 
reservoir for about 1.5 mm. and then 
expands into the subreniform, flattened, 
backwardly directed spermatheca, which 
lies upon the right side and terminates 
in a large tube a little longer than itself, 
opening into the oviduct. Into the
