Though extremely plentiful, no marked
varieties occur in this species in New
England, the only variation worthy of
note being in the color of the hind
tibiae. These are so constantly red
that a locust having them colored otlier- wise may be looked upon as almost sure
to belong to another species, atlanis,
minor, or extremus. Still, examples of
fefnttr-mliritm do occur with tibiae either pale (yellowish), or even greenish or
blue. These are, however, extremely
rare.
This is undoubtedly the commonest,
most ubiquitous, grasshopper " found
in New England, occurring everywhere
throughout the district in every plat of grass or sedge from sea-shore to moun-
tain-summit. The destruction caused
from time to time by locusts in New
England is usually ascribed to this
species, and with good reason, though
in some cases, particularly when caused
by migratory swarms, it is probable that utlanis is largely if not chiefly con-
cerned. In August, 1892, I received
complaints of grasshopper injuries to
garden crops, tomatoes, beans, etc., in
the vicinity of Norway, Me,
These
proved on investigation to be entirely
due to this species, which was very
abundant locally, and no specimens of
atlanis could be found. It is very plen- tiful at times on some of the islands off shore, as I have found it on Cuttyhunk,
Mass., and Block Island, R. I.., where it had the habit of collecting in great
numbers on the warm, sunny sides of
stone walls in the late afternoon and
remained over night.
While it is almost ubiquitous it is in
general most plentiful in meadows
and
the damper portions of mowinglands
and pastures, among the more dense
and succulent vegetation.
It reaches maturity in the latter part
of July and is found throughout the rest of the season; I have taken specimens
in the vicinity of Wellesley from July
25 to Nov. 8.

hind; abdomen short, above subglobose,
beneath flat; body covered with a short dense fine downy pubescence resembling mold ;
abdominal segments 2-5 ornamented at their apical margins with a peculiar series* of brown triangular emarginations impressed upon
the densely pubebcent surface; labial palpi pjointed, the first joint stout, longer than joint 2-3 united; claws with a tooth within. Type Melecta maculatu Cresson.
This genus comes apparently very close to Leiopodus Smith, but ditteis decidedly in the venation of front "wings; in the shorter abdo- men with its peculiar emarginated or zigzag ornamentation, which is quite unique in the group; in having the labial palpi 3-jointed not pjointed; and by the claws having a
strong tooth within.
An examination of the type of Mr. Cres-
son's genus Coelioxoides, last December, has convinced me that it has nothing to do with the subfamily Coelioxinae and that it should be placed with this family.
Family STELIDIDAE.
Subfamily I, STELIDINAE.
Melanostelis n. g.
Difters from the four other genera belong- ing to this family, namely, Protostelis Friese, Stelidomorpha Morawitz, Stelis Panzer and Parevaspis Ritsema, by having the second submarginal cell receiving both recurrent nervures.
In the genera mentioned, the second re-
current nervure is received jehindthe second transverse cubitus, or it is interstitial. Its other characters are: Mandibles tridentate; maxillary palpi z jointed; abdomen black or blue-black, with white bands, the last dorsal segment compressed into a carina at apex, while the last ventral segment is tridentate at apex.
Type At. beiheli n. sp.
Melanostelis betfieli 11. sp.- $2 .-Length q mm.
Black, clothed with sparse black
hairs, the face with a few grey hairs inter- mixed with the black hairs; abdomen above with subapical white bands on first four segments, those on the first and second
extending all across the back to the lateral margins, the one on the third much abbre- viated, while the one on the fourth is reduced to an oblong white mark; legs black, but the tibiae and tarsi have a piceous tinge in certain lights; tibiae at apex produced out- wardly into a strong angnlated process;
basal joint of hind tarsi much thickened; tibia1 spurs long, strong.
Hab.- Olympia, Washington.
Described from a single specimen, received from Mr. L. Bethel, captured June 2, 1897. The genera of the Stelidinae now known,
may he tabulated as follows :-
Genera of the Stelidinae.

stitial. , . . . . . 2
Second submarginal cell receiving both re- current nervures.
Abdomen black or blue-black, with white

2. Abdomen black or rufous, sometimes
ornate with white or yellow spots; max-
illary palpi I or2 jointed (rarely wanting); labial palpi 4-jointed.

Head as wide as the thorax; clypeus
not lengthened, well rounded ;
maxillary palpi I or 2 jointed;

men cylindrical, the segments
with large white spots; $ with
the apical margin of the sixth
segment toothed; f with the
seventh segment armed with a
tooth. Slelidt~aorpha Morawitz.
Scutellum with lateral teeth behind.
Head narrower than the thorax;
clypeus rounded not lengthened;
maxillary palpi 2 jointed; abdo-
men rounded, black, rarely with
small indistinct maculae; 8 with
the seventh segment rounded.
Stelis Panzer.
Abdomen black, or rufous and black,clothed with a scattered griseous pubescence;
mandibles tridentate.
Scutellum rounded and produced
behind over the base of the abdo-
men, the apex with a deep median
depression; apical abdominal seg-
ment in 8 tridentate.
Parevaspis Ritsema,
Subfamily 11, COBLIOXINAE.
Neopasites, n. g.
Differs principally from Phileremulus
Ckll., and Neolarra Ashm., by having a long marginal cell, which is much longer than the stigma, rounded at apex with a slight appen- dage. The front wings have two complete
submarginal cells, the first being the longer. It also differs from Pasites Jurine, Homa- chthes Gerstaecker, and Schmiedeknechtia Friese, in that the first recurrent nervure joins the first submarginal cell. Type Phil- eremus fulviueniris Cress.
Hoplopasites, n. g,
This new genus falls in a group of genera near Melittoxena Morawitz and Caenoproso- pis Holmberg: The axillae are acute or
toothed at apex, the scntelhim proper
(middle lobe) also armed with a median
tooth at apex, so that apically, with the acute axillae, the scutellum appears tri- dentate. The abdomen is red and black, the segments being banded with an appressed
whitish pubescence. Type Phileremus? pro- ductus Cress.
Family PAXURGIDAE.
Hylaeosoma n. g.
Comes nearest to the genera Dasypoda
Latr. and Calliopsis Smith, in having the first submarginal cell distinctly longer than the second, but differs from both, in having the median cell much longer than the sub- median.
The front wings have two recurrent ner-
vures, the first received by the first subinar- ginal cell, the second received by the second submarginal cell near its apex, the latter cell being almost quadrate, a little wider (or higher) than long.
The head, seen from in front is oblong,
nearly twice as long as wide, the eyes being very long, three times as long as wide. An- tennae clavale, the flagellum being gradually thickened towards apex. Maxillary palpi
6-jointed; labial palpi +-jointed, the first joint the longest. Mandibles tridentate at apex.
Type If- Zongicejs Ashm. MS. from St.
Vincent.
Cockerellia n. g.
To this genus belong most of the species described recently by Prof. Cockerel! nndei the genus Perdita.
It differs decidedly from Perdita, as de- fined and figured by Smith, in having much longer +-jointed labial palpi, the first joint being very long and usually somewhat
thickened, fully twice as long or even more than twice as long as joints 2-4 united; su- praclypeal plate quadrate, separated; clypeus at base trapezoidal: hind trochanters appar- ently without fiocculus; color aeneous, bluish, or black, usually with pale markings, the abdomen always banded or maculated; claws cleft. Type Pditaf hyalina Cresson.

Philoxanthus n. g.
Agrees very closely "with Coclwrellia in venation and palpia! characters, but is readily distinguished by the color of body which is wholly J-ellon, the abdomen being immacu- late; the stipraclypeal plate not being dis- tinctly separated; the clypens being" semi- circular at base; while the hind trochanters have a distinct flocculus ; cl:ms simple. Type Pcrdita testa Cldl.
Sepiu'iited at once from Perdita, Cockercllia, etc. hy the longer marginal cell which is much longer than the slig"ii.iii, fully twice as long, or as long as or longer than the first discoidal cell ; submedhn cell a little shorter than the median ; maxillary palpi +-jointed, the first joint verv long, fully 7 times longer than joinis 2-4 united, with a contraction at base. Type Psrdita zonalis Cr.

XerojbJiloea major n. sp. Length 7.5 mm., width across pronoturn 3.5 min. Larger,
more robust, and more coarsely pitted than vz'l-idis. The vertex proportiori~illy much larger than in viridis, and broadly, evenly rounded in front, nor at all even subangulate. Describedfrom two females in the National Museum, collected by Mr. E. A. Scliwarz in Virginia.
In the National Museum there is
also a specimen from the FiLcli cabinet, bear- ing the label ".^erojbhZoea major, Arkansas, W. S. Robertson." I have a large series of vi~idis Fah. from California, Colorado, hi- zona, New Mexico, Texas, Kansas, Alabamit, and Brazil. Ma}or differs as above stated from anything in this sericis. The forms of this genus, occurring in the Xortl~c~ist, should be colleci-ed in large series at many points.
Tettig-onia pomefvica Sign. This species is found in the United Stales, but has prob- ably been confused with /$da S^y, which it resen~bles in a most striking- manner. Besides some minor details, feomstrica is smaller and lacks the ~vliitisli lines on elytra. 1" have it from Illinois,Washington, D. C., Alabama and Louisiana.
Tet.?i&o?iia circellata 11. sp.
Length 6-6.5
mm.
Pale yellowish, the legs and base of
venter sometimes bi-idit orange. Front
usually with tn o longitu~linal black stripes on disc, a very short one on margin next each antenna, and one transverse on clypeal sntm-e; all these markings may be obsolete. Vertex with a black point at Lip and another at center of disc; t\!-o very short transverse lines behind, their inner ends embracing the ocelli, mid a large iincurved line on each side near the anterior inargiii, mising near the tip ; these mai-kings vary in intensity but, arc dis- tincL inall tlie apeciniens. Prouotum, except anterior margin, pale bl~ie; disc -with four black spots, one on either side before the middle and one on either side behind the middle; other srnall dots may occur between these. Scutel yellowish, with two more, or less exposcd dots :it base and transverse line, black. Elytra bright "biuc by reflected light, the apical margin transparent and the prin- cipal veins blackish.; by trmismitted light, the elytra appear deep smoky, "with a slight bluish tinge. Wings deep smoky Lhl-ough- out. Prosternum, dorsum largely, and some- times a median longitudinal row of small dots on venter, blacker blue-black.
