orifice.
Around the lateral margin there is
a row of about 32 sharp sword-like hairs. A long seta is situated on each side of the orifice, and on the ventral surface, near the posterior end there are a pair of short setae. The remains of the legs and antennae can be seen on the ventral surface.
Adult 9 .-Brown; eyes large, black;
length 1.63 mm. Antennae of seven joints ; joint 2 large, club-shaped ; joint 3 very long ; joints 4-6 short, cylindrical, equal in length ; joint 7 about half the length of joint 3. Wings large with the basal half and portions of the rest of the wing smoky.
Hub. On the underside of leaves of
grass growing on swampy ground, S. Paulo, Brazil. It is also accompanied by a species of ant (Camponotus).
dlewodes ~arvus n, sp. - Pitfa-case, -
Small, flat, black, oval; -94 mm. long;
usually enveloped in a mass of white felt- like hairy secretion. Dorsum with a longi- tudinal median ridge, and several transverse furrows. Marginal edge thickened, with a double row of crennlations. Vasiform ori- fice hemispherical. Operculum small, herni- spherical, not filling the orifice. A long seta is ~itnated on each side of the orifice. A pair of short setae extend caudad from the posterior part of the body; and another pair are situated on the ventral surface just cephalad of the middle.
Adult ?.-Body very light yellow, eyes
black; length .go mm. Wings transparent, dusted with a white powder. Antennae
short, slender, of seven joints. Joint 2 large club-shaped; joints 3-7 small cylin- drical.

-The eggs were kindly sent roe by Miss
Caroline G. Soule from Woodstock, Ver-
mont. The moth which I bred was deter-
mined by Dr. Hulst. The larva is not pre- viously described to my knowledge.
Bgfi
Regularly elliptical from top view,
the surface flattened, but obliquely; outline somewhat wedge-shaped from the side, the top slightly hollowed. Surface shagreened not reticulated, shining. Dimensions .4x 1 mm. Green when laid, dark red when re-
ceived and finally blackjust before hatching. Stage I.
Thick and stout binds; Geomet-
rids, the abdominal feet normal. Head bi- lobed, brown-black with pale setae ; width about .5 mm. Body all dark velvety brown, the abdominal and anal leg plates bright red, contrasting; four tiny yellow dorsal dots (paired oval light areas on the posterior edges of segments 5 and 7 which are not
tubercles). Tubercles conic, distinct, but concolorous ; setae short, dark, normal, with slightly swollen tips. Anterior edge of cervical shield and mouth reddish. The
larvae drop by a thread on being disturbed and twist up into a knot.
Stage II, Head about .8 mrn wide; all
dark vinous black as before, but the little bright paired dots are supplemented by a fainter pair on joint 8 and tubercle i of joints 5 to g is produced in to. a rounded prominence. Head rounded, clypeus pale.
S&ge III.
Head rounded, brown with a
short and thick black band on each lobe; width 1.2 mm. Tubercle i on joints 5 to 9 is high and subpapillose; white dots on joints 6and 7 anteriorly. Body still largely brown, but diversified with gray in dorsal and sub- dorsal diffuse and dotted bands on joints 5 to

8, spreading into a transverse shade on joint 8 posteriorly and 9. Tubercle i of joints 6 and 8 is larger than elsewhere and lighter hrown, with a dark tip. Thorax and joints 11 to 13 mostly dark.
Sfaye ZV.
Very angular and stick-like.
Head flat before, the apex retracted, gray brown, darker streaked on the vertex; width 1.9 mm. Feet of joints 3 and 3 appressed. those of joint 4 protruded and with swollen bases; body angled sharply at joint 4 in rest; slender for joints 4 to 7, joints 8 to 13 much thicker; tubercles i on joints 5 and 6 en- larged; joints 8 and 9 swollen, forming col- lars, the tubercles prominent; joints 10 to 13 nearly smooth. Dark brown, frosted with
gray; rusty brown dorsally,especially on the prominent parts; shaded with whitish be- hind joint 8; 11 to 13 dark gray. Below
mottled gray and brown like bark. The
prominent bases of the feet of joint 4 are light hrown. The larva is much streaked and
dotted; the dorsal paired pale dots are gone. Stage V. No essential change. The
head is about 2.7 mm. wide; there is a pair of thick anal prongs. The humps of joints 8 and g are variegated with shades of brown and whitish, especially a distinct dark tri- angle over tubercle i and a dorsal triangle alternating with this.
The species is single brooded. Eggs
hatched the first part of June and larvae spun early in August, passing the winter as pupae. The moths cmerged in May of the following year. The larvae fed on maple.
PROCEEDINGS OF THE CLUB.
12th May, 1899.
The 209th meeting was
held at 156 Brattle Street, Mr. J. W. Folsom in the chair.
The death was announced of Mr. Edward
Winslow Cross, recently elected a member of the club.
Mr. S. H. Scudder read a letter from
Clifford Pribhle of Topeka, Kan., a boy of 13, upon night flying butterflies. He said that in the autumn of 1898 he had found
Anosia plexippiis almost every night and that on one occasion had taken Amblysci~tes uiatis around lights.
Mr. j. W. Folsom read a paper on the
number of segments in the head of insects. It was based upon embryological studies in the Collembola, Mr. Folsom arriving at the conclusion that it is composed of seven seg- ments. The paper will appear in Psyche.
Much discussion followed.

SUPPLEMENT TO PSYCHE,-11.
BY SAMUEL H. SCUDDEE, CAMBRIDGE, MASS.
Between 1860 and 1878, and cspeci-
ally during the eight years subsequent
to 1870, years which witnessed his
greatest activity in the study of Orthop- tera, Stil proposed more than four hun-
dred generic names for Orthoptcra,
many of them in minor papers now
diflficult to procure. The characters of these genera were largely elucidated by
means of analytical tables, which were
sometimes repeated in a fuller and more
definite manner in some subsequent
publication. To obtain a full knowl-
edge of his limitations of these genera
it is often necessary to refer to several places, and I therefore prepared for my
own use and now publish as a conven-
ience to others the following alpha-
betical index to these genera. No
distinction is made between genera and
subgenera, and the family to which
each belongs is indicated.
Not to repeat titles too frequently in
the index I give first a list of the papers in which the genera occur and prefix to
each a Roman numeral which is used
to indicate it in the index. These titles are arranged chronologically, though it
should be noted that the last, which
appeared after Stkl's death, was actually presented to the Swedish Academy
more than three months before the one
which precedes it, which was sooner
published and to which the posthumous
paper was in a sense introductory.
The list contains two papers not quoted
by Brunner in his R6vision clu systfeme
des Orthoptferes, and omits one (Re-
cherche~ sur la systhne des Mantides -
1873) given by him, as it proposes no
new genera. All the papers were pub-
lished in Stockholm, and all but the
first in octavo.
