cies (A angelica Grote) which feeds on the ash and syringa, trans- 
forming to the pupa state Sept. 14. His larva seems to differ in 
the “numerous fine black linings, among which may be traced two 
forming a vascular stripe, and two similar lateral stripes on each 
side.” Lintner also speaks of “four dorsal white lines, posteriorly 
black” on the prothoracic segment, and also of “short stiff red hairs 
on the sides of the second and third thoracic segments, and indeed 
it is evident that the larvae of the two species differ considerably 
in markings. Our larva, on the other hand, appears to be identi- 
cal with that described by Harris (Correspondence, 307) under the 
name of Astasia torrefacta ? Sm. and Abb., the two last stages of 
which he describes. He found it on the burdock, and says that it 
“eats leaves of willow well,” and further on states that he found 
one “on a leaf of Prunus virginiana.” 
This conspicuous hairy caterpillar, which evidently feeds ex- 
posed on the leaves, seems to be somewhat omnivorous in its tastes 
and sometimes feeds on herbaceous plants, as the burdock. Hence 
it apparently belongs to the same category of hairy pencilled wliite- 
and-black-spotted and tufted caterpillars as those of Halesidota, 
those of the Liparidse, and certain species of Noctuidse, as Charadra 
deridens , etc. It is noteworthy as being in this respect exceptional 
among Notodontians. 
PARTIAL LIFE-HISTORY OF PHEOSIA RIMOSA PACK. 
The larvae described below were observed at Brunswick, Me., 
Aug. 17, feeding on the aspen ; the last stage was assumed Aug. 
25. It will be particularly interesting to observe the first stage 
of this larva, and to see whether the horn is well developed. 
Third stage. — Length 11 mm. Head very large and full, wider 
than the body ; the vertex somewhat divided and produced into 
two very slightly marked lobes ; the head is somewhat narrower 
above than below. The eighth abdominal segment is somewhat 
swollen, and bears a large blood-red horn, which is rather obtuse at 
tip. The suranal plate is much rounded, and smooth on the upper 
side. The anal legs are much smaller than the four other pairs, 
which are rather large. The thoracic legs are stout and brown in 
color. The lateral ridge is prominent and of a yellowish hue ; be- 
neath this ridge there is a lateral conspicuous brown stripe extend- 
ing upon the legs. The spiracles are brown. The body is glaucous 
green, of the same hue as the under side of the aspen leaves, with 
yellowish sutures.
