INSECTS INJURING CHESTNUT LEAVES. 3^ 



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 bauds, 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 tinged with 

 red. (Harris.) 



7. Tetrads crocallaia Guen6e. 



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 aud 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 hairlines; paler beneath with a large dirty brown patch in- 

 closing two light browji spots on the sixth and seventh rings. Length when at rest, 

 23mm . when crawling, 28""™. 



Pupa. — Length 17™™ ; 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 aud two beneath, very much hooked at the tips. (Goodell.) 



Moth. — In this species the male antennse 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 Gu^n. 



The caterpillar of this fine moth was found June 10 at Providence, 

 and June 19 spun a loose, slight, thin cocoon in a partially roUed-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 JE. obtusaria lived on the touch-me-not 

 {Impatiens noli-me tangere). 



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 ; marbJed with dark livid slate-colored, wavy, 

 broken, fine close-set lines. Supra-anal plate large, triangular ; surface somewhat 

 rough ; four piliferous tubercles on the hinder edge or apex, aud 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
