INSECTS INJURING OAK-LEAVES. 145 
Larva.— Onisciforni, 19 mm long. Head purplish-brown. Four purple and three 
white lines drawn very close together form a dorsal band running the length of the 
body. Subdorsal line bright red, from which arise six red spines (longest on central 
segments) studded with yellowish-red spinelets; betweeu the spines and on the fifth, 
sixth, eighth, and ninth segments are reddish spiny warts. The spines and warts 
are on elevated ridges. Beueath the subdorsal line are two pairs of purple longi- 
tudinal lines on a yellowish ground ; the pairs divided by 
a red line. The breathers [spiracles] are on a similar red 
line, and are guarded or ornamented by spiuy warts, like 
those meutioned above. Legs of a sort of yellowish-olive 
color, prolegs, or rather tubercles, and under side of body 
of a reddish tinge. Varies considerably; one very beau- T ' ^J 
tiful variety has all the red of the typical larva replaced by Fig. 49.— Parasa chloris. 
brimstone yellow. (W. V. Andrews.) 
Cocoon. — About half an inch long, spun on the midrib of a leaf, oval, shining brown- 
ish-black. 
Moth. — In general shape like Euclea, but yet quite distinct from it. The species 
may be known by its grass-green thorax and the broad grass-green band which 
separates the brown margin of the wing from its base. Ground color pale cinnamon- 
brown. A broad, short, vertical tuft between the bases of the antennae. Thorax 
above, grass-green. Middle green band on the fore wings straight on the outer edge; 
within it is slightly excavated and follows the inner edge to the base of the wing. 
The hind wings are concolorous with the body, and above are a little paler within the 
outer edge. Expanse of wings, .94 inch.

This interesting species, according to MS. notes by the elder Le 
Conte, feeds in Georgia on the oak, chestnut, aud wild cherry. 
Larva. — Length, 16 mm ; September 3 aud 4. The body is oblong-square, and seen in 
section subtrapezoidal, the dorsal surface being in general flattened, though still 
somewhat convex; the dorsal area being from one-half to two-thirds as wide as the 
creeping disk or uuderside of the body. The body ends in a long, slender, fleshy 
projection or tail, which is somewhat spinose and slightly forked at the end. Along 
each side of the dorsal surface is a row of short, thick, retractile tubercles, bearing 
peculiar stout spines, which are whitish tipped with brown at the end. The third pair- 
from the head is situated apparently on the second abdominal segment, and is twice 
as large as the others ; those on the eighth abdominal segment are much larger than 
the other abdominal tubercles, which are minute; the short spines on this pair are 
whiter than those on the other tubercles. A brown line externally washed with a 
paler hue bounds the sides of the back. There is a lateral row of small spine-bear- 
ing tubercles arouud the edge, the middle of each tubercle being raised or convex. 
The spiracles are minute, white, somewhat elevated, and situated on a darker round 
area. Low down between the two rows of tubercles is a row of smooth kidney- 
shaped depressed spots. The head is of a chestnut color, the labrum paler. The 
under side, or disk, is pale flesh color, edged above with a reddish stripe, which 
becomes reddish-brown above. The body still higher up is of a rich velvety, dark 
flesh-red brown, some individuals being much darker than others. The under side 
of the "tail" is carneous, becoming reddish above, and dorsally of a rich brown, 
with the spinules blackish, or pale at the base and brown-black at the tips. 
Moth. — P. f rate ma differs from P. chloris in being smaller, while the prolongation 
of the broad green band in the fore wings along the inner margin to the base of the 
wing is very much, at least two-thirds, narrower. The larva, judging by several
