INSECTS INJURING OAK-LEAVES. 145 



Larva. — Oniscifortn, IQ""" long. Head purplish-brown. Four purple and three 

 white lines drawu very close together form a dorsal band rnnuing the length of the 

 body. Subdorsal line bright red, from which arise six red spines (longest on central 

 segments) studded with yellowish-i-ed spinelets ; between the spines and on the fifth, 

 sixth, eighth, and ninth segments are reddish spiny warts. The spines and warts 

 are on elevated ridges. Beneath 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 spiny warts, like 

 those mentioned 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- v 



tiful variety has all the red of the typical larva replaced by Fig. id.—Parasa cldoris. 

 brimstone yellow. (W. V. Andrews.) 



Cocoon. — Abouthalfau 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 antennse. Thorax 

 above, grass-green. Middle green band on the fore wiugs 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. 



200. Parasa fraterna Grote. 



This interesting species, according to MS. notes by the elder Le 

 (Jonte, feeds in Georgia on the oak, chestnut, and wild cherry. 



Larva. — Length, 16™™ ; September 3 and 4. The body is oblong-square, and seen in 

 section subtrapezoidal, the dorsal surface beiug in general flattened, though still 

 somewhat convex; the dorsal area being from one-half to two-thirds as wide as the 

 creeping disk or underside of the body. The body euds 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 

 tbe 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 bad:. There is a lateral row of small spine-bear- 

 ing tubercles around 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 carneoua, becoming reildish above, and dorsally of a rich brown, 

 with the spinules blackish, or pale at the base and brown-black at the tips. 



Moth. — P. fraterna diflPers from P. chloris in being smaller, while the prolongation 

 of the broad green baud 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
