ooetft. From tin- angle extends a more or less distinct slightly curved series of irreg- 
ular diffuse dark spots to the inoei angle ; this is usually represented by a faint shade. 
l>i-Mal dots alike in each wing, being small and blaek. Hind wings with the single 
Line in the middle of the wing straight, with the outer series of diffuse spots as on the 
fore wings. Expanse of wings, 2 to 2.10 inches. 
'254. MetanewM quercivoraria Gueu6e. 
(Larva, PI. Ill, fig. 8.) 
Feeding on the oak, a pale green span worm, marked with red, changing to a 
brownish-gray chrysalis, from which a beautiful sickle-winged moth comes. 
In Georgia it was observed by Abbot on the oak and poplar in April ; 
it pupates at the beginning of May, and the moth appears at the end 
of the same month. We have raised this from the oak, the moth issuing 
on May 3. 
i 
Larva. — Pale green, with the sutures and sides reddish, a double angle bordered 
with reddish on the second segment behind the head ; another more salient on the 
sixth, and finally another on the tenth ; the fifth segment has on each side a small 
pointed tubercle. Head and feet concolorous. 
Pupa. — Reddish horn-brown, with the abdominal sutures reddish; caudal spine 
acute, large and flat. Length 13 mm . 
Moth. —Body and wings pale whitish ash. Wings thickly covered with fine speckles. 
Fore wings with three lines, the usual inner and outer lines, and a third wavy sub- 
marginal hair-line. The two inner lines distinct, of even width, a little oblique, not 
waved ; the innermost line situated exactly on the inner third, the outer line on the 
outer third of the wing. Costal edge stained with reddish on the end of the outer 
line. Submarginal hair-line wavy, sinuate, reddish, situated half-way between the 
outer line and the edge of the wing, and disappearing below the second median 
venule, scalloped between each venule, much more distinct below than above. On the 
hind wings a single brown line, and traces of a submarginal wavy line. Beneath paler 
than above, with the lines reproduced beneath and dull colored; the third submar- 
ginal line on both wings partially obsolete, but clearer than above ; fringe reddish. 
Expanse of wings 1.50 inches. It ranges from Maine southward. 
255. Nematocampa filamentaria (Guene"e). 
The singular caterpillar of this species is found on the oak, maple, 
as well as the currant and strawberry, in June, becoming a chrysalis 
in New England by the 20th of the month, the moth appearing early 
in July and flying about through the summer. Its habits in Missouri 
have been thus described by Professor Riley : 
June 1, 1870. — Larvae were found at St. Louis, Mo., on thorn and laurel oak. One 
changed to pupa June 4, hauging between a few threads on a twig. The moth issued 
June 12. One larva was also received June 26, 1883, from J. H. Clark, of New York, 
which he found feeding on a rose-bush. It changed to pupa in a slight web of 
thread June 27, and the moth issued July 5, 1883. 
Some larvae of this insect are infested by Tachinids, the eggs of which were de- 
posited at the side between the fourth and fifth segments. (Unpublished notes.) 
Larva. — Body cylindrical; head large, with two unequal pairs of long, slender, 
fleshy filaments situated on the third and fifth abdominal segments, the posterior 
pair shorter than the others, curled at the end and finely tuberculated. Head pale 
rust-red, full, slightly bilobed, flattened in front ; marbled with a still paler hue.
