slightly tinged with yellow above, short on disc of tnesothorax and sparse on disc of mctathorax. Wings hyaline, veins brown.
Legs black, more or less brownish on tibiae and tarsi, the four anterior tibiae white at base and on the anterior pairextending down a short distance in front is a brownish-yellow line; pubescence whitish tinged with yel- low on tarsi beneath.
Abdomen black, shin-
ing, almost nude except at base where there are some white hairs and at apex where the pubescence is rather dense; yellow bands on segments 1-4, those on 1-2 broadly inter- rupted on the disc and on 3-4 very'siightly so; all are somewhat margined on the lateral apical portions.
Venter black, apical margin
of the segments brownish.
Habitat. Visalia, Cal, (H. 0. Wood-
worth), May 9. One specimen.

mm. Black, abdomen with narrow yellow
bands broadly interrupted on the sides.
Head black, very finely and densely punc- tured on vertex; clothed with whitish pube- scence, tinged with yellow above; all of the face beneath the antennae except three small spots on clypeus near the base and one on the labrum, and mandibles except tips, yel- low; the yellow on the sides of the tace ex- tends up a little higher than the antennae. Antennae black, flagellum pale yeliowibh beneath. Thorax entirely black, clothed
with a dense whitish pubescence which has a brownish-yellow tinge above. Wings smoky becoming darker toward apical margins;
veins black. Legs clothed with short white pubescence; black except a line on the an- terior femora and on all the tibiae in front (interrupted on middle of posterior pair) and the tarsi entirely except a narrow black line on posterior pair behind, and the claws which are mole or less brownish, yellow. Abdomen black, clothed with a very short pale pubescence; segments 1-5 with narrow yellow bands each slightly interrupted on the middle and broadly so latterly forming thus four elongate spots on each segment, those on the sides being the broadest. Venter

LIFE HISTORIES OF NORTH AMERICAN GEOMETRIDAE. - IV. BY HARRISON G. DYAR, WASHINGTON, Dm C.
Thrina endrojiaria Gri. and Rob.-The
mature larva has been described by Goodell (Can. ent. xi, 194).
His description, though
short, is correct, if the structures that he calls " tubercles " be understood to be low rounded prominences of the skin and the words 6, 8 and 7th segments be changed to 6,8 and 9th. Further as Goodell does not count the head as joint I, his numbering of the seg- ments' should be increased by one in each case to correspond with mine.
Egg. - Several together, usually in a
straight row of 5 to 9, sometimes more; ir- regularly elliptical, scarcely flattened, one end distinctly truncate, a little convex with a rounded rim. Neatly, distinctly reticulate, the cell areas resembling round pits, the pit- ting extending also over the truncate end. Slightly bluish green, shining, soon turning dull reddish with a dark (.pot on the truncate end.
Size .6 x .4 x .3 mm.
Stczge I-
Head round, pale brown ; width
about .3 mm.
Body whitish translucent, a
rather broad pale cinerous subdorsal band, leaving the dorsal and lateral areas pale. Setae fine, pointed, white, obscure. Appear- ance pale grayish, obscurely marked. After eatitig they became translucent green, the head brown, no marks.
Stage II.
Head round, slightly bilobed,

pale brown; width .5 mm. Body smooth,
slender, whitish green, finely creased an- nulate, not shining, no niarks, no projec- tions.
Stage III.
Head round, slightly bilobed,
broad, green, slightly brown dotted on the sides of the lobes; width .y mm. Body
smooth, green, a little whitish, especially on the substigmatal fold above which is a faint darker green band on joints 3 to 13, or this band may be blackish ; spiracles black. The scgnients are annulate on the anterior half ventrally. The larvae sit at an angle with a supporting thread from the mouth.
Staye IV.
Head rounded, bilobed, green,
a reddish suffusion on the side; width 1.3 mm. Body green, sordid on the Lhorax and joint 13, elsewhere opaquely yellowish green; a brownish suffusion on joint 10 stigmatally; spiracles on joints 5 to 9 in black patches, ,.
Hie elongated central segments are folded- wrinkled on the' posterior third; lateral fold rather distinct. The skin is smooth, almost without marks.
Stfig-e V.
Head as before, the brown pn-tch
on the side larger; width 1.8 min.
A stig-
matal shade on joints 10 lw 13 iind patches on 6 and 7 distinct., Tubercle ii of joints 7 and 10 a little enlarged and shaded with brown. Otherwise smooth, opaque yellowish green, a little shaded with brown; a brown dot on joint 3; tubercle iv bluck the whole length; joint 8 more or less distinctly col- lared. There is much variation in different larvae in the iiinonnt of hrown; the poste- rior end, joints 10-13, may be a11 brown and a large patch on joints 6 and 7.
Stage VI. Head green only centrally and
on the vertex, heavily shai.lciI with purplish brown over the side of each lobe, darkest posteriorly; rounded, bilobed, higher and wider than joint 2; width 2.5 mm. Body
cylindrical, smooth; a collared elevation on the dorsal half of joint 7 (tubercles ii and iv) ; ii and iv of joint 10 and iv of joint 6 with slight clevatiuns or joint 6 even collared on the ventral half; the dorsal tubercles all a little prominent especially on joints 3, 9 and 10: Color dull, not shining; under
ground green, all shaded with purplish
brown, the exact amount varying. Joints
10 to 13 are nearly entirely shaded, the ven- ter of these and of 2 to 4 contrastingly pale green. There is a dark spot on tubercle iv of joints to g with a tendency to transverse bunds. Tubercles dark, relieved by white patches in the dark and prominent parts. Spiracles black, ringed with whitish outer shades. Anal plate rounded; two subanal
prongs. The larva resembles a twig that 16 partly green. One example was all brown
except on the face and dorsally on joints 2 and 3.
Eggs were obtained at Brookhaven, Long
Ishind, N. Y., late in June and the larvae spun towards the end of August, passing the winter as pupae. Fully grown larvae were found at Morris Plains, N. J.
Food 'f)lants. Red and white oaks and
chestnut.
