THE SPECIES OF HADROTETTIX, A GENUS OF OEDIPODINAE. BY SAMUEL H. SCUUDER, CAMBRIDGE, MASS.
Hadrotettix was established in 1876,
oil t~ clumsy, strikingly banded Oedipo- dine with long' and rather coarse anten- nae, from the Arkansas River, described
by Say as GrylZzds i'rifasciatus and fig- ured in 1828 in his American Entornol-
ogy. No species has since been added
to the group,* althougli one from Ne-
braska has been catalogued by lir~iner
on several occasions. I have for some
time had in my collection a Mexican
species of very different appearance, so far as the marking's of the wings go, and recently Mr. Morse has brought from
California still another widely different species. Accordingly I append descrip-
tions of the two additional species, leav- ing that named by Brimer to be described hj him. The four species known to me
may be separated by the following-
table : -
Table of the. species of Hadrotettix.
al. Wing's crossed by a broad fuscous
band, as broad as the inetazoua, and
following the hind border nearly to the
anal angle ; hind tibiae coi'sil red.
*Thomas, however, twice described the original species uudm new names.
P. Band of wings with no taenia
di~ectecl toward the base in the hn-
moral field . /å´~-zyasciatzis
P. Band of wings sending a hurner-
a1 taenia at least one third the
distance toward the base of the
wings , pracilis.
a2. Wing's crossed by a narrow band
not following the hind bolder toward
the anal angle, or by 21 mere cloudy in- f~iscation.

tegmiiia inenibranaceo~is~ <he dense
retic~il~ition of the base exfeucling lwt little beyond the middle ; wings
crossed by a distinct narrow fuscous
band with a humeral faienia; hind

I have specimens from Valentine and
Fort Robinson. Nebi-., and Hot
Springs, S. Dak., received from Bru-
nei. ; as well as from Las Animas, Col., Bosque Co., Tex., and Fort Whipple,
Ariz. It therefore has probably much
the same range as the preceding. It
is 1 little smaller than that species. 1 have also received this species from
Brunei' as coming from Nebraska and
labelled H. minor Brun. MS.

Pro- no~ini of nearly uniform coloring", brown- ish plumbeous or ferrnginons, but with the lateral lobes often more or less feebly albes- cent, particularly in Lhe male, rarely obscurely p~iiictatc with fuscous, the lateral carinae prominent but rounded on the metazona,

Cylindrical, the ends rounded, one
end a little more tapering'ly so than the other; a scarcely perceptible flattening of the cylin- der, parallel to the leaf as laid. Twelve neat low ribs, reaching almost to the smaller end, becoming dotted at termination; stopping abruptly at the larger (micropylar) end in a circle of large, quadrangular, indistinctly edged cells, at the inner angles of which are a circle of white dots, one for each rib. Within this the micropyle is somewhat coarsely re- ticulate. Ribs thickly crested with a double alternating row of white dots. Cross-stria- fine, parallel, faint.. Fine dark green; the ribs and circle of dots appear white. Size .65 X .55 X .so mm.
Stage I. Head rounded, not bilobed,
brown-black, not shining'; width .3 mm.
Body cylindrical, slender, feet normal; cen- tral parts of segments bcaring tubercles i and ii larger, collared, 2-annulate, the interscg. mental parts smooth; ends shrunken. Dark vinous, almost blackish, the slender, inter- segmental paits of joints s to 9 pale, sordid whitish with dorsal and subdorsal vinous lines, so that the body looks obscurely dark vinous banded.
