PSYCHE.
SOME OLD CORRESPONDENCE BETWEEN HARRIS, SAY, AND P1CKERING.-VI.
SALEM, Sept. 9th, 1825.
Dear Sir,
I take the present opportunity to for-
ward you a few specimens of insects.
The brown butterfly inhabits the bald
summits of the White mountains of
New Hampshire and appeared to be
confined to those regions. Mr. Nuttall
described to me a year ago an insect
from the same locality probably identi-
cal with this, but unfortunately his
specimens were lost. The white Pi-
eris occurred not unfrequently about
the base of the mountains, together,
with a fine species of Apatura? with a
broad white band across the middle of
each wing, of which I was unable to
procure more than a single specimen.
The small Lycasna was taken in a bog
meadow in this vicinity. Your Cicin-
dela formosa I have frequently met with
in this vicinity, and particularly, it oc- curred in great numbers, for two suc-
cessive years, at a sandy spot near
Cambridge in this state: the other Ci-
cindela, of which I have sent you the
two extremes in the variation of the
markings, is distinguishable at first
sight from C. sexguttata by the con-
vexity of the elytra and also by the
comparative dullness of the colors
when alive, occurred abundantly at the
same locality and I have met with it
no where else. The Pollyxenus I met
with two or three times this last spring under the bark of the Walnut; on the
side of the White mountains under the
bark of a dead pine I took a single
specimen of the genus Craspedosoma
which I have by me now though it is
very much injured. The black Lep-
tura is also from the sides of the White mountains. The Tipula is found in
ditches in bog meadows in this vicinity
and makes a curious appearance when
flying, the six legs are then extended
and become very conspicuous, slowly
moving along, while the means by
which the motion is produced are not
seen. I have filled up the box with
duplicates from my collection (which
unfortunately are rather scarce particu- 'larly of the more uncommon species) of
the genera Leucopsis, Plea Leach,
Xylota?, Syrphus, Nemotelus, Sto-
moxys, Hydrometra, Curculio, Lu-
perus, Clytus, Cychrus, kc; if among
these you find anything interesting I
shall be able to give you further infor- mation.
Yours, with respect,

29 8 PSYCHE. [ August 1892.
October I 2t11, 1825.
I thank you much for the specimens
of ins. yo11 were so good as to send me, as well as for the agreeable letter which accompanied them ; in the care of Mr.
Robinson they all arrived in excellent
order.
The Pollyxenus you met w. is ["per-
haps" erased] the P. fasciculatus Nob.
if so the species has a wide range.
Pieris, I have not met w. this sp.
before & do not know it, have you both
sexes ?
Limenitis arthemis, Drury, the But-
terfly w. a broad white band across ea.
wing.
Lycaena phlosas, var.
Cicindela formosa. I am surprised
to learn that tins is f'd in y'r region ; I've never met w. it here. I think you
will find the green Cicindela to be a
variety of C. 6-guttata, I have some
specimens on which the punctures are
very large so as to give the surface a
very rough appearance.
The Craspedosoma must be interest-
ing, I have not yet found a sp'n in this country.
The black Leptura is my L. -pubera.
"The Tipula found in ditches &c"
is Ptychoptera clavipes of authors.
The brown butterfly is my Hip-
parchia semidea.
I received a mutil-
lated specimen from Mr. Nuttall, but
yours is in good order. I propose to
figure it in my 3rd or 4th vol. (the
marbling of the under sides of hind
wing is much as in H. sernele, but the
dark lines are broader.)
The Leucospis is a small sp'n of my
L. afKnis.
The Prince of Musignano will deliver
you this letter if he goes so far as Sa- lem, if not he will put it in the Boston post office.
Melandrya labiata Nob.
DESCRIPTIONS OF OESTRID LARVAE TAKEN FROM THE JACK RABBIT AND COTTON-TAIL.
BY C. H. TYLER TOWNSEND, LAS CRUCES, N. MEX. Our jack-rabbits and cotton-tails are
frequently badly infested with bots, but the former are usually the worse in-
fested. The jack-rabbit of this region
is the Lefus callotis of Wagler ; while, if I am not mistaken, our cotton-tail is the sage hare, Le*s ar^emz'sia of Bach-
man (or possibly L. 6achmamWaterh.)
Jack-rabbits are sometimes seen with
immense, unshapely lumps on their
shoulders, sides or backs. Whether
or not these are due to bots, I can got
say positively, as I never succeeded in
securing a rabbit in this condition.
I*
have been told that when these lumps
are cut open, they reveal simply a col-
lection of sacs filled with a watery sub- stance, but without bots.
It may seem strange to record that
the jack-rabbit bot is a Dermatobia,
while the bot of the cotton-tail is, as a rule a Cuterebra. Such, however, is
the case. While I have not observed
any instance as yet of the Cuterebra in-
