HIPPISCUS (H.) VARIEGATUS sp. nov.
Similar in form and color to H. co~actus but with the disk of the prothorax generally rather lighter and more often marked by a pallid decussate stripe, which is here found even in the $2 ; sculpture of the head not differing from that species, excepting that the ridges about the foveolae are if anything duller and that the frontal costa is slightly sulcate below the ocellus. Antennae luteous at base, beyond reddish fuscous. Prono-
turn as in H. compcacfus but with the hind margin more obtusely angled, and the carina of the prozona independently though feebly arcuate. Tegmina cinereous or hoary, becom- ing semipellucid apically, with markings much a& in H. cumfactus, but less regular, more maculate, more oblique, the central spot usually very broad, the marginal field much more numerously spotted, and the spots of the axillary area generally more distinct, be- ing deeper and more sharply defined; the tegmina are relatively longer. Wings also relatively longer and narrower, but with mark- ings precisely as in the preceding species, ex- cepting that the basal color is variable (as indeed it may be there), varying from a pallid tint through pale lemon yellow to saffron and coral red, the last in a single example. Hind femora bright yellow within, thrice heavily banded transversely with black, dull clay yellow without, very obliquely banded with blackish or fuscous; hind tibiae yellow with an orange tinge sometimes infuscated a little just beyond a broad clear basal belt; spines black tipped.
Length of body, $,28 mm., ?,37 mm. ; of
tegmina, 3, 28 mm., 9, 35.5 mm.
I have seen specimens from Penn-
sylvania (Schaum coll.) , Maryland
(Uhler, Bruner), Washington, D. C. -
(Brunei"), and Georgia (Morrison), in
the east, and Indiana (H. Edwards),
southern Illinois (Kennicott) , and To-
peka, Kansas, collected by Cragin
(Brunei-), in the west. Mr. Bruner also
tells me that he has specimens from
Virginia, Decatur, Ah., Chattanooga,
Tenn., and Mississippi, in the south,
and from Indiana, Illinois, Missouri,
Kansas, and eastern Nebraska, in the
north.
Described from 13 3, 8 9, part of
them from Mr. Henshaw's collection.
HIPPISCUS (H.) SUTURALIS sp. nov.
Hiċ´f>piscu rugosus McNeill !, Psyche, 6, 63. One of the smallest species of the genus, with somewhat compressed body, expanding but slightly on the metazona, of the same tone of color and general appearance as the three preceding species. Head dusky above, obscure olivaceous below, the summit nearly smooth with a nearly circular, very shallow and smooth, feebly quadripartite scutellum ; lateral foveolae small, shallow, triangular, a little elongated ; frontal costa feebly convex but depressed at and immediately below the ocellus, at its upper extremity very feebly bifoveolate. Antennae dull testaceous at base, blackish fuscous apically. Pronotum much as in H. com.ċ´pacftts but the angle of the posterior margin distinctly obtuse.
Tegmina with the darker blackish fuscous markings predominating on the basal half, so that before the great central quadrate dark spot which includes the triangular base of the outer discoidal area, there are but two pairs of small quadrate cinereous spots be- neath each other in the marginal and inner discoidal fields; the apical portion of the marginal field is blackish fuscous and in the

outer discoidal field, the base of which is mostly pellucid, there is a single slender, transverse belt of fuscous above the apex of the ulnar fork and beyond it scattered fuscous cellular spots; the axillary area is wholly blackish fuscous, and the sutural stripe yel- low, bright, distinct, and not very narrow. Wings pallid at base with a very broad black- ish fuscous arcuate band which strikes the margin below the third lobe and narrows
slowly toward the anal angle which it scarcely reaches; above it does not narrow and is separated from the humeral stripe, which runs only half way to the base, by a slender pallid line ; apically the wing is pellucid, but in the male a little clouded at the margin and with blackish cross veins. Hind femora pale yel- low within, the base and two broad transverse stripes black, dirty yellow externally with oblique black stripes on the upper half; hind tibiae pale dull yellow with a dull orange tinge apically, more or less infuscated on the middle of the outer side, the tips of the spines black.
Length of body, 27 mm. ; of elytra, 26 mm. Moline, Ill., J. McNeill. Described
from I 3. It bears a striking resem-
blance to H. (A".) neglectus, but is not the species mistaken for that form by
Thomas.
HIPPISCUS (H.) OCELOTE.
Oedipoda (Hi//iscus) ocelote Sauss., Rev. mag. zool., 1861,398-399 ; Orth. nova Amer., 2, 29-30.
Hi$i>iscus ocelote Thorn., Syn. Acrid. N. A., 200-201 ; Sauss., Prodr. Oedip., 84-85 ; Addit. pi-odr. Oedip., 26-27.
This Mexican species is unknown to
me, but from Saussure's excellent de-
scription and tables evidently belongs in the series near where I have placed it.
It is found, according to Saussure, both in the warmer and cooler zones at Cor-
dova and Guanajuato.
HIPPISCUS (H.) SAUSSUREI.
Oedi-poda Jiddemannii Thorn., Rep. U. S. geol. surv. terr., 5, 456 ; 6, 720-721.
Oedii>oda Jialdemanii Thoin., Syn. Acrid. N. A., 130-132.
Hi$/iscus /;aIdmumzi Sauss., Prodr.
Oedip., 85-84.
Not Oedipoda haldemanii Scudd.
Considering the insufficiency of my
description of Oe. haldemanii it is not
surprising that both Thomas and de
Saussure should have mistaken another
species for it ; having still the types of that species in my possession, I am able to. determine accurately what it is. In
the present species the pantherine mark- ings of the tegmina are much obscured
(though still evident) by the great ir-
regularity of the margins of the fuscous spots and their general blurring.
All of my specimens of the present
species come from Texas, from Dallas
and San Antonio. Specimens in the
collection of Mr. Samuel Henshaw are
also from Texas, collected by Schaupp.
Brunei" sends me specimens from San
Antonio, Tex., collected by Newell,
and Saussure's specimens come also
from Texas; but Thomas, besides
Texas, gives New Mexico, Kansas, Ne-
braska, Colorado, Wyoming, and Da-
kota; very likely he has confounded
other species with this, and that its true home is in and about Texas only.

I have seen the type of Oe. obliterata
in the Halle Museum or what may be
regarded as the same, a f from South
Carolina, Zimrnermann, labelled "oblit-
erata" in Burmeister's handwriting. I
have also seen in the Jardin des Plantes a specimen marked as Blanchard's Oe.
@dchri/ennis Ms. As stated above,
under H. phoenicoptems, I have also
seen the type of that species at the
EIalle Museum, and have been able to
correct my former error regarding- this
species.
A pair of specin~ens of H.
tuberculutus together with one of a dis- tinct genus were seen by me in the
Hunterian Museum at Glasgow marked
Gr. obscurus Fabr. which is Dissos-
teira saucia, an Old World species.
This is a northern species, common
in the spring in all the northern states and throughout Canada as far north as
the arctic region.
I have seen many
specimens from the upper McKenzie,
and Great Slave Lake, collected by
Kennicott, and others collected by Rich- ardson's party are in the
British Mu-
seum which also reports it from Hudson
Bay. North of our boundaries it is
found from Nova Scotia (Jones) on the
east to the Red River of the North
(Scudder, Dawson) , and Calgarry,
Alberta (Bean in Henshaw's collection),
and in our own country occurs as far
west as Dakota and Montana (Thorn as)
the Big Horn Mountains and Ft. Mc -
Kinney in Wyoming and the Black
Hills of S. Dakota (Bruner in litt.),
and is stated to be found on the west
coast of North America by Walker ; if
so, this is probably north of our boun-
dary. In the United States it is found
in the east as far south as the middle
states,-Pennsylvania, New Jersey, and
the District of Colunlbia (Walker, Os-
ten Sacken, Bruner, Coll. Am. ent.
soc.) in some abundance, and is re-
ported also from South Carolina (Zim-
mermann) and Florida (Saussure,
Walker) , where it must be rare ; and in the west, in Missouri and at Topeka,
Kansas (Bruner in litt.), in Nebraska
(Thomas), Lincoln, all eastern Ne-
braska and Holt County and other parts
of the Sand Hill region north of Platte
River, Nebr. (Brunei- in litt .) , Missouri (Saussure, Austin), and Colorado

(Thomas), while Walker reports a
specimen, perhaps by error, from Oaja-
ca, Mexico.
There is much variety in the mark-
ings of this species, so that I have been inclined at times to separate several dis- tinct forms. Specimens from Nepigon,
north of Lake Superior, for instance,
are very dark, while those from Ne-
braska not only have the outer half or
even more of the tegmina hoary pallid,
seen to a certain extent also in some but not all specimens from Manitoba, but
the pale vitta which separates the hum-
era1 and axillary areas of the hind wings involves not only the anal vein but also, at least in the outer half of the wing,
the posterior ulnas vein and the attin-
gent cross veins as well, considerably
broadening the vitta. The arcuate dark
band of the wings is of variable width ; usually broad and involving the pos-
terior margin, it sometimes is very nar- row and in both cases may not reach
the posterior margin, and in one $
from Manitoba there is no trace of a
band on the anal area but only a nearly
uniform infuscation of the wing beyond
the colored base. The depth and ex-
tent of the darker markings of the teg-
inina, as well as the amount of contrast with the paler portions are also ex-
tremely variable, giving these organs a
very different appearance in different
individuals; but in no case do they
strongly resemble any other species, so
that this species may readily be distin- guished from them in the almost total,
usually total, absence of any maculation in the ulnar area of the tegmina, or indeed often of the basal discoidal field. Speci- mens from east of Long. 90ċĦ too, usually have the extreme tips of the wings dis-
tinctly and deeply infuscated, especially in the 3, and those west of it scarcely
ever show any sign of it, but exceptional instances occur.
I append a description of the colors
of living females taken in Massach~l-
setts :-
Prevailing color a light ashy plumbeous, slightly darker above, specked with dark plumbeous, tinged slightly beneath with
reddish. Head uniform; mouth parts uni-
form and tinted like under surface of body. Eyes dark brown, specked with yellowish and with a narrow slightly curved transverse median streak of yellowish brown, turning upward posteriorly. Antennae dirty yellow- ish at the base, beyond of the color of the head. Pronotum with a longitudinal dark
brown streak with indistinct edges along the middle of the lateral lobes, and from the middle of this a descending vertical streak scarcely paler than the ground; posterior edge of pronotum a yellowish brown of the color of box wood. Tegmina of the body
color blotched with fuscous and black, and with the axillary fold yellowish brown.
Wings coral red at base, the arcuate band fuscous deepening to black, the humeral line pale yellow and the apex nearly hyaline. Legs of the body color, the inside of the hind femora having the basal half a prussian blue, the distal half very dull lemon yellow with a transverse streak of deep lblue at one third the distance from the middle; hind tibiae dull lemon yellow, hind tarsi tinged with reddish. Abdomen above tinged on the first three segments with reddish brown, espec- ially toward apex ; ovipositor of the color of the body when not black.
