mens from Fold county- two 01' each
variety (P. n. ncbrascencis and P. n.
vdncris). Structural chsiracteristics
conform well with the description,
excrpt thnt in llirce of' Hie four cases the fastig'ium is plainly suloalo. The
other specimen - P. n. nehrmcencis
corroborated the description of Scud-
cler. Fro'i1eni:il spine not "å erect''
hut slightly recumbent. Extremity of
male abdomen only feebly clavnte.
In the short winged variety P. n.
nebrascenc& the two specimens at
hi~ild show marked variation in teg-
mina ; alike in width, they differ in
length, and in the foi m of distal exh'cm- ity. The specimens agree in size,
but tegmina sire six and nine mm. in
length respectively. The shoi ter teg-
mina end more abiuptly and the apex
is more acute Ilia11 in the longer wii~g. Two males of each vaiiety from Ford

THE CLEAR-WINGED SPECIES OF THE OEDIPODINE GENUS MESTOBREGMA.
BY SAMUEL H. SCUHUER, CAMBRIDGE, MASS.
Most of the described species of the
genus Mcstobregrna, like the type of the genus, have the wings distinctly crossed mesially by a fuscous band of greater or less width. In one species, however, M
kiowa Thoin,, the wings are pellucid,
except for the fuscous veins and for the occasional faint clouding of the wings at the normal point for the band, or the
heavier infuscation of the cross veins in this region.
In the collections brought from the
Pacific coast by Mr. A. P. Morse, arc
three species of the genus with wings
showing at most no greater indication of a cross-band than in the species men-
tioned ; indeed one of them is that spe- cies, which has never before been recorcl- ed from west of Utah. They wet e found
in successively more southern regions.
The broad-winged form, M. /'/m~a, was
obtained only in northern Califoi nia neai Mt. Shasta. The narrow-winged species
occurred, one, M. hynlinum, in the San
Joachin valley from the latitude oC San
Francisco to that of Los Angeles, the
other, M rosacetm, from the southern
edge of the San Joachin valley to Yuma,
Arizona.
The species may be separated as fol-
lows :

LIKE HISTORIES OF NORTH AMERICAN GEOMETRIDAE. - XIII. BY HARRISON G. DYAR, WASHINGTON, D. C.
Syncklora ~'laitcaria Guen.
The larva has
been described (as nibivora Rilcy) by Riley, Saundera and French but not in much de-
tail.
Eg8.
Elliptical, strongly flattened on two
sides, thefliit faces concave, sunken, the edps well marked but a little rounded; side view slightly wedge shaped, the broader end trnn- cate roundly, elevated in its center so as to be almost quite round like the narrower end, and is so except for a slight annular flatten- ing, noticcable from side view. Surface all finely hexagonally reticulate, the reticulations not strongly raised. Pale, slightly greenish yclluw, shiiiing. Size .6 X -5 X -3 mm.
Later turns pale red.
Staye I. Head round, slightly bilobed,
pale brown, mottled with pier, with shorL, white, glandiilar setac; width ahout .3 mm. Body cylindrical, smooth, tubercles rather large, especially iv, which is cylindrical and produced with a conicsil tip. Setac white ; on abdomen short with flattened enlarged tips, except iii (of joint 5) and iv (joints 6 to 9) which is very long and has a bulbous tip. This seta is sticky and bears, on its base principally, the fragments which adhere to ihe larva. Snbdorsal setae of thorax and joint 12 also prolonged, but much shorter than the long lateral ones. Dark brown-black mot- tled with ocherous, especially on joints 12 and 13, which look lighter; traces of a dark dorsal line.
Stage IT.
Head rounded, slightly bilobed,
of the colorof the body; width .4 mm.
Body
as before, the setae glandular but much
shorter, iv still the longest and arisisig from a son~ewhat produced base. Color dull
brown, a whitish ground speckled with brown. Skin p~ui~ilarly roughened. Lwva rat.lier short and thick. It becomes entirely covered with fragments of the flowers it feeds on, which adhere to the sticky setac.
Siage Z/Z.
Head rounded bilobed, clypeus
rather high; shagreened, setae ob&cure; lu- teous whitish, speckled with brown, heaviest near tlic suture and on the sides of the lobes; width .8 mm. Body thick and robust, dor- sum slightly flattened; tubercles angularly elevated; hctae small except iv, which is large and arises from an elongated tubercle. No marked lateral projections, the slight angular projections nearly alike for all the tubercles. Gray brown, densely frosted with white gt-arniles, an obscure, double, white dorsal line, divided by brown; traces of a white lateral band on the angular elevations poste- riorly, on anal plate and anal feet. Tuber- cles pale, setae white. All the dorsnm except thorsix and joints 12-13 covered with frag- ments of flowers which adhere to the spiny base of the short stiff seta iii.
Feet pale.
