PSYCHE.
SOME OLD CORRESPONDENCE BETWEEN HARRIS, SAY AND P1CKERING.- VII.
SALEM, Nov. 14, 1825.
Dear
I received your letter,
dated Oct. 12th, by mail in due season : of that white Pieris I have but a single specimen which is, I believe, a male,
though it is so much injured that I will not be certain about it; it does not
apparently differ from thiit which I sent you which is as good a specimen as
could be procured; as the species
occurred frequently and within a short
distance I most probably saw both
sexes, and if there were any difference
between them, at all conspicuous, I
should have observed it: my attention
was so much distracted by botany
during my short visit to the White hills that I neglected the insects more than I ought to have done- and besides my
whole collection of minute insects was
lost, so that I did not bring home
above a hundred species. Of these I will mention a few trusting that yo11 will
excuse me, if they prove to be familiar
to you, as my opportunities of becoming
acquainted with American insects are
at present very limited, amounting
principally to Turton's Linnaeus. I
expect however to get access to your
publications this Winter.
A species of Nothiophilus (not dis-
tinguishable by a short description from N.. aquaticus of Europe) occurred on
the bald part of the mountains to the
very apex of Mount Washington. At
the same locality I took a Thanasimus,
differing from the description of T.
formicarius in having the anterior fourth of the thorax black -its length is a
little over a fifth of an inch.
I. The perfect insect, line above natural size. The hind tarsus.
3. Last joint of the tarsus. 4. Front
view of the head. 5. Elyt.
On the road through the Notch I
found a Cimbex - length of the body
nearly one inch, tergum black-blue
with a yellow spot on each side of the
5, 6, and 7 segments, wings fuscous at
the middle and tip, it is a female.
The insect of which I send you a
sketch* I am unable to refer to any
genus I can find described; it belongs
to the family Cantharidae ; it differs from Lytta in having the head gradually tap-
ering behind the eyes into an indistinct *[Determined by Mr, Samuel Henshaw as Cejihuloofi ungulare Lee.]

neck, and narrower than the thorax ; the description of the antennae of Zonitis
does not apply as you will see ; and the elytra are not abruptly attenuated as in Apalus (with the habit of the two last
genera I am unacquainted) ; the outer
division of the nails serrated beneath ; a single specimen was taken on flowers
of the Heracleuin lanatum on the sides
of the White M.
If any of these prove new to you I
will send you drawings in the Spring.
My collection of insects is not at present very extensive amounting to not above
1500 species collected by myself in this vicinity. Of those insects described by
you in the appendix of Major Long's
2nd expedition I have the following,
Cistela sericea, Spectrum femoratum
(my specimen is also a male), Chaulio-
des sesricornis, Dolerus inornatus, D.
arvensis, Foenus tarsatorius, Sigalphus
sericeus, Chalcis microgaster, Tiphia
inornata, Pompilus fascipennis, Cero-
pales bipunctata, Eumenes fraterna.
Mr. Little of Boston has taken two or
three specimens of your Clytus specio-
sus near that place, and Mi-. Oakes of
Danvers has also taken a specimen.
Under the bark of rotten pine stumps
I have several times met with the mol-
luscous animal which I have sketched-
in its living state it seems to differ from Limax in the complete destitution of a
shield, but in specimens preserved in
spirits it is seen that the shield covers the whole of the upper part of the body
taking the place that the cloak usually
does? It does not agree with any of the
subgenera of Cuvier. I should like to
know whether you are acquainted with
this animal in Philadelphia.
Yours,
CHARLES PICKERING.
Rarely in these times do the great univer- sities of the world confer their highest honors upon students of the natural sciences; far more rarely has it been that such honors have been conferred upon those whose merits have been won by investigations in systematic entomology. The more noteworthy, hence,
is the bestowal, recently, by the University of Heidelberg, of the honorary degree of Doctor of Natural Science, on Baron C. R. v. Osten SackenÌÔL'qu de scientia entomo- logica excolenda, novisque rationibus illus- tranda optime meruit." The honor was all the greater because it required the unanimous approval of the Faculty conferring it. It is an honor well deserved, and none will rejoice over it more than the American entomolo- gists, and especially the American dipteroia- gists.
Baron Osten Sacken's work has been
chiefly related to American dipterology, but the ripe fruits of his wide experience, and broad grasp of principles have enriched all dipterology, and, I believe, all entomology. Others there are and have been who have
won enviable honors in systematic dipter- ology; others who have written more ex-
tensively than he, but no one has written more that will be appreciated in the future than, has Baron Osten Sacken. His work
has not been free from error, for that is im- possible, but it has always been conscientious and rich with suggestions. However radically one may differ from him in certain of his views, their cogency will not'be questioned. Baron Osten Sacken's health has not been good for some years past, but his friends will rejoice that it has of late improved, and will hope for many papers from his pen yet to appear. 5. W.

November 1892.1 PSTCHE. 347
This species so far as known is con-
fined to the northern half of the United States in the general vicinity of the
Rocky Mountains. Specimens before
me come from the upper Missouri and
Yellowstone (F. V. Hayden), explora-
tions in Dakota under Gen. Sully (S.
M. Rothhammer), Nevada (H. Ed-
wards), Utah (P. R. Uhler), about
Rangeley on the lower White River,
western Colorado (S. H. Scmdder),
Colorado, 55001, probably at the eastern edge of the foot-hills (H. K. Morrison,
in S. Henshaw's coll. and my own),
and Yuma, Arizona, collected by Wick-
ham (Bruner) .
I have seen but two specimens with
red hind wings, both females from
Rangeley, Colorado.
HIPPISCUS (X.) TOLTECUS.
Xan/hz'p/us toltecus Sauss., Prodr. Oedip., 91-92.
If I have correctly identified Saus-
sure's species it has a wide range.
He
records it from Mexico alta. I have
seen specimens from Spring Lake Villa,
Utah Co., Utah, Aug. 1-4 (E. Palmer),
Helena, Montana. June 21 (A. S.
Packard) , and Laramie River, Wyom-
ing, (L. Bruner.)
HIPPISCUS (X.) ALTIVOLUS sp. nov.
Dark obscure brownish fuscous, not very
robust and of small size. Head dull dirty cinereous with numerous more or less clus- tered blackish points, most abundant above; summit relatively broad, scarcelyat all tumid, subrugulose, the vertical fastigium indistinct from the low and dull bounding walls,
closed behind by the arcuate incurving of the lateral walls, separated distinctly from the tolerably deep, biareolate median foveola ; lateral foveolae rather small, triangular, subequiangular ; frontal costa of moderate breadth, fading and not expanding below, but little contracted
at summit, broadly and
shallowly sulcate throughout. Prothorax
but slightly expanding on the metazona,
the dorsal area plane, scarcely indentate at the front margin of the metazona,
sparsely verrucose and in addition abun- dantly but bluntly and obscurely arenaceous ; process rectangulate; median carina low, subequal, not arched; lateral carinae tolera- bly pronounced ; lateral lobes bluntly subru- gulose on the metazona, marked with a large subquadrate blackish spot on the prozona. Tegmina very short, extending when at rest but little beyond the hind femora, dirty cin- ereous with obscure dark brownish fuscous transverse more or less blended bands,
broader than the intermediate ashen ground, and therefore occupying much the larger
space even on the apical half which is
scarcely at all vitreous ; sutural stripe obscure testaceous. Wings pale dull citron at base with similar reticulation, subvitreous apically with black reticulation and between a strongly arcuate, moderately narrow, blackish fulig- inous band which narrows in passing toward the anal angle, which it fails to reach, and does not narrow above ; it lies entirely in the apical half of the wing, leaves four marginal lobes free, and appears not to be at all sepa- rated from the humeral vitta whose outer limit is in oblique continuation of its outer curve and which reaches almost to the base; the basal half of the costal margin is testa- ceous. Hind femora brownish cinereous
externally, with rather obscure oblique
brownish stripes, the inferior surface dull coral red like the tibiae which are more or
