INSECTS INJURING OAK-LEAVES. 181 
reddish brown ; vertex white. Fore wings, with two inner reddish-brown diffuse 
lines, the inner situated half-way between the base of the wing and discal dot, 
curved and more or less scalloped, the outer curved, situated just be\ond the discal 
dot, and joining the third outer line on the second median venule ; it is broader and 
still more diffuse than the basal line. Outer line straight, bent back at a very acute 
angle on to the costa, the line above the bend being more or less angularly curved 
and dilated on the costa ; an oblique white line extends from the bend to the costa 
just below the apex, which is white above and blackish below, with a large reddish- 
brown patch extending irorn below the apex to the second median venule. Discal 
dots in both wings black ; scales flattened as usual. Hind wings with a single slightly 
curved line just beyond the middle of the wing. Expanse of wings, 2. 2D inches. 
253. Eutrapela transversata (Drury). 
This rather common caterpillar was first found by Abbot feeding on 
Clethra alnifolia. In the Northern States it feeds on the maple (Good 
ell) and currant (Emerton), and we have found the moth just emerged 
•resting on the leaves of the red maple. In Florida, however, we have 
found it at Crescent City in April feeding on the live oak. It was 
reared by the U. S. Entomologist at Washington, where on May 6 it 
spun a rather dense cocoon between the leaves, the moth emerging 
May 31. The larva occurred in Virginia June 26, where it feeds on the 
oak (Koebele) ; in Massachusetts the caterpillar occurs in June; thus 
it is apparently double-brooded in Florida and the cotton States, but 
single-brooded in the Northern States. 
Larva. — It is about 1 inch in length and quite uniformly dark gray, with a paler 
gray, elongated spot each side of the first abdominal segment. The lateral margin 
forms a flattened carina, on which the stigmata are situated. Both edges of this 
carina are purplish, and the small stigmata white with black annulus. Piliferous 
warts small and black. There is a large, prominent, transverse, bilobed projection 
of a blackisb color on the fourth abdominal segment, which is bordered in front by a 
whitish triangle. Behind thiu projection, and parallel with its lateral angles, run 
two whitish dorsal lines to the anal plate. There are also two small black conical 
tubercles on the last segment. Head concolorous with the body, the face marked 
with a dull black semicircular spot, the angles of which end near the base of the 
mandibles. 
The smaller larva, which measured about three-fourths of an inch in length, is 
dark purple, with the head entirely dull black. The projection on the fourth abdom- 
inal segment is in this specimen still divided into two oval and rather prominent 
tubercles which are orange externally. (Eiley.) 
Pvia.— Large and long, not very stout and short compared with that of E. clem- 
ataria; acutely pointed at the end of the abdomen. In color slightly pale ash-mahog- 
any. The last segment much corrugated longitudinally at the base of the cremaster, 
but the ridges are not swollen anteriorly as in E. clemataria. Cremaster flattened, 
conical, not discolored with black, with two terminal excurved thick setae, and only 
one pair of minute subdorsal-lateral setae. Length, 21 mm . 
The moth. — It may be recognized by its large size, the very falcate wings, the 
obtusely bent outer line on the fore wings, and by the submarginal shade or row of 
• spots on both wings; the hind wings extend farther than usual behind the tip of 
the abdomen. Fawn color, varying to ocherous ; head chocolate brown in front, the 
vertex white. Fore wings with the inner line usually present, curved, consisting of 
two large scallops meeting on the median vein and pointing inward. Outer line 
straight, more or less distinctly bent near the apex, turning at right angles into the
