DESCRIPTIONS OF THREE NEW SPECIES OF ALEURODIDAE FROM BRAZIL.
BY ADOLPH HEMPEL, S. PAULO, BRAZIL.
Alewodes horridus n. sp. - Pupa-case.-
Length, I mm. ; elliptical in outline, flat; light yellow in color.
The dorsal surface is
covered with white secretion, arranged in a median longitudinal row, and a submar- ginal row on each side.
Around the margin '
there is also a very short fringe of white wax. These details are however obscured
by a mass of long yellowish, hair-like secre- tion, that envelopes each individual. De- nuded of wax, the margin is found to be
doubly crenulated, with the posterior end of the body rounded and the anterior end
forming an obtuse angle. The dorsum is
slightly -wrinkled, and has a short median longitudinal ridge, extending from the ante- rior end to nearly the middle of the body. Vaisiform orifice subelliptical, broader than iong. Operculu~n hemispherical,
nearly fitting the orifice, the free end notched. A long seta is situated on each side of the orifice; two on the caudal end of the body; and two on the ventral surface of the body jnst cephalad of the middle. NO traces of antennae or legs were found. Adult .- 1.08 mm. long, yellow, eyes
black; wings transparent, yellowish, covered with a white powder. Antennae of seven
joints. Joints 3-7 fine, cylindrical, slender ; joint 2 large, club-shaped.
Legs long and
slender, nearly reaching to the apex of the closed wings.
flab.-On the underside of leaves of
guava, Psidium sp., from S. Paulo, Brazil. Accompanied by a species of ant (Cremas- togaster).
Atcurodes fu~?'#ennis n. sp.-Pwpa-case.- Elliptical, convex, black, 1.8 mm. long. There is a prominent median longitudinal, dorsal ridge, and about six transverse
fur-
rows. The lateral margin is thick with a conspicuous groove on the dorsal surface, and a short fringe of white wax on the ven- tral surface. Kear the posterior end, around the vasiform orifice, there is
a large hemi-
spherical area, nearly transparent, but dusted with white secretion. The lateral margin is slightly notched in places, but not crenu- lated. Vasiform orifice hemispherical ;
operculum small, rectangular, fitting the Pwhs 8 394-195 tprt.1903). h4)://psychrcnlclub or@/S-394 html

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 he seen on the ventral surface.
Adult $2 .-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).
Aleurodes $arwus n. sp. - PU-pa-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, hemi- spherical, not filling the orifice. A long seta is situated 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 Ej? .-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.
Hab. -On the under side of leaves of
Maytenus sp. S. Paulo, Brazil.

LIFE HISTORIES OF NORTH AMERICAN GEOMETRTDAE. - 111. BY HARRISON G. DYAR, WASHINGTON, D. C.
Butraj4eZa (Selenia) atc$hera-fta Walk.
-The eggs were kindly sent me by Miss
Caroline G. Soule from Woodstock, Ver-
mont. The moth which I hred was deteii-
mined by Dr. Hulst. The larva is not pre- viously described to my knowledge.
Egg'.
Regularly elliptical from top view,
the surface flattened, hut obliquely; outline somewhat wedge-shaped from the side, the top slightly hollowed. Surface shagreened not reticulated, shining. Dimensions .4x I nun. Green when laid, dark red when re-
ceived and finally blackjust before hatching. Stage I.
Thick and stout black 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 platesbright 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 mm wide; all
dark vinous black as before, but the little bright paired dots are supplen~ented by a fainter pair on joint 8 and tubercle i of joints 5 toy is produced into a rounded prominence. Head rounded, clypeus pale.
Slop IZI.
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 hands on joints 5 to
