Noy. 1886. ] 

AND OOLOGIST. 

hatched in the spring of 1887. They were kept 
in the refrigerator until Sept. 7th, a period of six 
weeks, when, to my astonishment they began to 
emerge, and I found half a dozen out in the box. 
I do not know the degree of cold to which they 
were subjected, but I am satisfied that the atmos- 
phere of the refrigerator was never above 45°, 
while it must have been as low as 34° at times. 
The box they were in was pasteboard, and open 
at the top. 
This result satisfies me that Danas archippus, 
with a supply of food plants can range within the 
arctic regions and flourish at as high a point as 
civilization has ever reached—U pernavik,— where 
the summer heat sometimes reaches 60°, although 
in that latitude such heat as that is considered 
phenominal, between 45° and 50° being the aver- 
age summer temperature. 
What the minimum of heat is, which is neces- 
sary to mature this butterfly I do not know, but I 
have not a doubt that it would develop in the 
chrysalis and emerge under a steady temperature 
of 42°. The maximum of its endurance of cold 
is not known, but in this latitude it is sometimes 
subjected to a temperature 30° below zero, al- 
though the average winter temperature is about 
zero. 
The Archippus butterfly must be among the 
hardiest of New England Lepidoptera and rank 
with the Graptas and Vanessas for its endurance.

Sphingidae of New England. 
BY WRIGHT & BATES. 
SPHINX CA ROLINA.—Linn. 
Head, thorax and abdomen dark gray with a 
brownish tint; a black line extends around the 
front and sides of the thorax, which is sur- 
mounted by a triangular patch of lighter color, 
bordered with black. 
On each side of the abdomen 1s a row of five 
bright orange spots, encircled by black, decreas- 
ing in size toward the apex. There is a faint 
black dorsal line, and the segments are faintly 
edged with white. 
Anteriors dark brownish-gray, with a white 
spot at the base; four irregular lines cross the 
wing between the base and the disc, inclined pos- 
teriorly toward the base; discal spot white, edged 
with black; beyond the disc is a faint dark-brown 
curved band expanding into a patch below the 
disc; the space following this patch is light- 
brown; a black wavy line extends along the 
outer margin, followed by an irregular whitish 
line which becomes obsolete toward the apex; 
a black line, shaded anteriorly with very light- 
gray, extends from the apex toward the disc; 
fringes brownish-gray, dotted with white. 
Posteriors light-gray, with a light-brown basal 
spot, followed by three light-brown bands cross- 
ing the wing, marginal space light-gray, with a 
light-brown band extending from the apex, 
where it unites with the last band along the mar- 
gin, to about the centre of the marginal space. 
Under side of anteriors dark-gray, crossed by 
two parallel lines just beyond the disc. 
Posteriors are of‘ a lighter shade than the ante- 
riors and are crossed diagonally, near the middle, 
by three lines, which are followed by a band of a 
darker shade. 
The under side of the abdomen shows a row of 
four black ventral spots. 
Mature larva green, with seven oblique white 
stripes on -either side, bordered with bluish ; 
minute white dots, edged with a purplish shade, 
are scattered over the body, and the last segment 
is edged with white; caudal horn is curved back- 
wards and is furnished with short black spines. 
Pupa dark-brown, with a detached tongue case. 
Transformation subterranean. 
Food plants: Tobacco, tomato and Datura 
stramonium.

We hope our readers and correspondents will 
kindly overlook the many errors which crept into 
our department in the last number. Our assist- 
ant undertook to correct the proofs, and follow- 
ing the example of many entomologists, changed 
a number of names. Still, as we prefer the old 
ones, they may be found under the head of 
“Hrrata.”

Rare Birds. 
Mr. Charles E. Hoyle of Millbury, shot, on Saturday, at a 
pond in Oxford, two of the rare Golden Plover out of a 
small flock that had been frequenting the pond for several 
days. These birds, so eagerly sought after by gunners 
along the coast during their flights southward in the fall, 
are extremely rare so far inland. They were undoubtedly 
driven in by the northeast storm of last week. 
A young Goshawk was captured in a house in Worcester, 
Monday, having entered the room through an open window.
