INSECTS INJURING CHESTNUT LEAVES. 347 
the anterior spot being round and the posterior and larger one triangular. The hind 
wings are light ashen brown at base, passing into dusky ocher-yellow. The large 
specimen is a female, and was taken by Professor Agassiz on the northern shore of 
Lake Superior. The body is of a dusky ocher-yellow color, tinged on the sides and 
•on the legs with red. The fore- wings are light rosy buff, with brownish ocher clouds 
and bands, two silvery spots near the base and a whitish dot near the tip. The hind 
wings above and all the wings beneath, are of a deep ocher-yellow color tiuged with 
red. (Harris.) 
7. Tetrads crocallata Guene'e. 
This moth has been raised from a caterpillar found feeding on the 
chestnut by Mr. L. W. Goodell, at Amherst, Mass. It became a pupa 
July 15, within leaves drawn together with a few threads. (Canadian 
Entomologist, xi, 193, 1879.) 
Larva. — Mature larva, one specimen. Head brown, much narrower than the body ; 
two large dark brown spots in front. Body stout and very slightly attenuated ante- 
riorly, the first and second rings much narrower than the rest and retractile into the 
third. About a dozen minute black tubercles on each ring. Reddish brown covered 
with numerous wavy hair lines; paler beneath with a large dirty brown patch in- 
closing two light brown spots on the sixth and seventh rings. Length when at rest, 
23mm . wae n crawling, 28 mm . 
Pupa. — Length 17 mm ; ashen gray, tinged with reddish and speckled with brown ; 
a brown dorsal stripe, obsolete on the abdominal segments. Thorax paler with a 
small dorsal brown spot. Head brown, with a vertical red streak. Abdomen dark 
brown beneath speckled with reddish, the anal segments with a transverse dark 
brown dash above. Wings pearly ash with a submarginal row of seven brown spots. 
Caudal spine round, with two long hooked forks ; four slender bristles at the base, 
two above and two beneath, very much hooked at the tips. (Goodell.) 
Moth. — In this species the male antennae are simple, and the wings slightly bent on 
the outer margin. It may be readily recognized by its uniformly bright ocher-yellow 
body and wings. A broad oblique coffee-brown band on the fore-wings, extending 
from just beyond the middle of the outer edge to the apex ; discal dot not large, but 
distinct on each wing. On the hind wings, a single straight line, not reaching the 
costa; sometimes this line is wanting. Expanse of wings 1.75 inches. 
8. Endropia obtusaria Gue"o. 
The caterpillar of this fine moth was found June 10 at Providence, 
and June 19 spun a loose, slight, thin cocoon in a partially rolled-up 
leaf, transforming June 20 to a pupa. The moth was observed after it 
had emerged, but flew away, though not till after I had assured myself 
that it was most probably if not certainly E. obtusaria of the chocolate 
variety. Abbot's larva of E. obtusaria lived on the touch-me-not 
(Impatiens noli-metangere). 
Larva. — Head small, flattened, much narrower than the body ; squarish, the sides 
being parallel. Dark slate brown, clypeus and adjoining region pale ash, forming a 
light triangular spot on the front of the head. Body increasing in width from the 
eighth abdominal segment to the head ; marbled with dark livid slate-colored, wayy, . 
broken, fine close-set lines. Supra-anal plate large, triangular; surface somewhat 
rough ; four piliferous tubercles on the hinder edge or apex, and two behind the mid- 
dle. A row of four to five small dark tubercles on the three thoracic segments, and 
four dorsal tubercles on each abdominal segment, those near the hinder edge of the 
first and fifth abdominal segment larger than the others, and connected by a ridge
