we find the following characters as-
signed to them : " Tete aussi large que
le thorax " (p. 32). LG Ce genre [Thlip- somyza], dont Ie caracthe le plus ap-
parent est I'abdomen cornprime et muni
de soies sur les bords des segments, a
pour Ie type le T. compressa, Wied.,
Bomtylius id.. Fab., d' Alger. Nous y
joignons deux esphces nouvelles, ^gale-
ment du nord de YAfrique, dont l'une,
Ie T. hetetoftera, difffere des autres par la premiere cellule post6rieure ouvertc. Ces Bombyliers se distinguent encore
des autres par les soies qui bordent les segments de l'abdomen,"
Of Tt casianea, he says : " C'est peut-
etr6 une varii5t6 du 57 compressu."
In his specific descriptions, Macquart
gives a quite different type of coloration for his species, and in his figure of
T. heferoptera the bristles of the abdo- men are conspicuously indicated. Fur-
thermore, the abdomen, like the whole
body, is bare and elongated. All of
these characters are so u hiinmelweit"
from the Bombylius type, to use Wicde-
mann's own expression, that one is sur-
prised that the identity of our forms
should have occurred to Mr. Coquillett.
It is interesting to observe that both
Schiner and Loew refused to accept
Amictus Wied. as being distinct from
Thlipsomyza, based as it was chiefly
on the open or narrowly closed first
posterior cell, the sole character assigned to Thlipsogaster by Rondani. Euryca-
renus Loew seems to be a nearly allied
genus.
The moral of it is that Rondani's
genera, like Walker's species, are to be accepted with fear and trembling.
ARKANSAS MELANOPLI - 1,
BY JEROME MCNKILL, FAYETTEVILLE, ARK.
The recent publication of Scudder's
excellent Revision of the MelanopIi
by making it possible to recognize
with certainty those species which have
already been described suggested the
propriety of placing on record the
species of this group which are known
to occur in Arkansas. This seemed to
be the more desirable because almost
nothing is known of the Orthopteran
fauna of this State. The list here given is undoubtedly very far from complete
as the collections upon which it is based have been made almost entirely in the
seven or eight counties of Northwestern
Arkansas. Altogether nineteen species
representing six genera are known.
Melanoplus includes fourteen of these
species and two of these Met. baconi
and Mel. sylvaticus are apparently unde- scribed. ,Two others Mel. i-mf~td~cus
Scudd. and Mil. imfiger W. were
described very recently in Scudder's
monograph cited above.

Of the remaining five genera, it may
be said that the occnrrencc of Phoeta-
Jiotes, Hespeyufetfix and Dendrotettzx was quite to be expected. Campylocantka,
however, has not been reported so far
east before and Paratylatropidia has
hitherto been known by a single pair
of specimens from localities so widely
separated as Texas and Dakota.
Paroxya may certainly be expecied to
occur in the southern and eastern parts
of the Slate. It i5 altogether probable
too that a considerable number of
Texas forms will be found in the valley
of the Red River in Southwestern
Arkansas.
The keys which follow have been
based directly upon females, though
they should apply nearly equally well to males.

334 PSYCHE. [March 189.
Campylacantha oliwacea Scudd.- I have
specimens from Fort Smith and Fayette-
ville as well as from Mackey, I. T. The
earliest recorded date for its capture
is August second, the latest October
eighth, though doubtless some specimens
survive until settled cold weather which generally does not come until after
Christmas. It is a rather rare species
so far as my observation goes, though it is sometimes abundant locally. It oc-
curs in dry pastures.
Hesfte~otetfixpa/e?zs/s Scudd. - A sin-
gle female was found in the summer of
1897 near Buffalo City, Marion County
which I refer to this species with some
hesitation. It was found in the mouth
of a gully at the foot of the divide be- tween Big Buffalo and White Rivers.
Timber occurred sparsely here but vege
tation was abundant. A long search in
this vicinity failed to reveal any more
specimens.
Dendroteftix guercus Riley.-This spe-
cies is represented in my collections by one male and six females, all except one female captuied near Clifty, Cairo11
Co., June twenty-ninth. The female
referred to was taken near Elkins,
Madison Co., July thirty-first.
ParalyZot~opidia brunneri Scudd.-This
very interesting and apparently very
rare species is found in Arkansas. It is represented in my collection by a sin-
gle pair, male and female, captured near Clifty, Carroll Co., June twenty-ninth.
I refer these specimens unwillingly to
the same species as they are remark-
ably different in the distinctness of the lateral carinae which are obsolete in the female and very distinct in the male,
and in the fastigium of thevertex, which is not perceptibly declivent in male and exceedingly prominent, while in the
female it is moderately declivent and
distinctly less prominent. In other re-
spects they agree as well as male and
female of the same species usually do.
The single pair, male and female, known
to Scudder were from Dakota and Texas
respectively. As the male was an im-
perfect specimen, the structure of the
furcula could not be given.
The Arkansas male shows not the
faintest trace of furcula and the last
dorsal segment is not interrupted in the median line. The female at first glance
has very .much the appearance of a short winged Melanoplus binittatus Say.
A NEW VARIETY OF CHIONASPIS FURFURUS FITCH, AND NOTES ON OTHER SPECIES.

Chionas^fis furfures Fitch. var fulwiis. n. gated ovoidal and convex. Length also vari-
var.- Scale of female.- Shape variable, able; length including exuviae 3, 2; and z some pyriform and flat, others quite elon- mm. The width of these are quite constant,
