below each eye, and two small spots near the upper border of each eye; two 
black spots on outer borders of clypeus; labrum and mouth parts brownish; 
last segment of palpi banded with black, other segments spotted. Basal segment 
of antenna green, second segment with a black ring; remainder of antenna 
brownish. Three pairs of large black spots on pronotum, symmetrically arranged. 
Mesonotum also with three pairs of black spots, one behind the wings. Wings 
of moderate length, somewhat acute at tips, hyaline; longitudinal veins green; 
costal and radial cross-veins mostly blackened at one or both ends; gradate 
series wholly black; branches of radius black at base; wings as a whole dark. 
Length of adult, 13 to 16 mm. 
(As previously pointed out, a series of six or eight varieties in the inter- 
antennal marks exists, but there appears now to be small necessity for their 
formal designation. Furthermore, there is a marked difference in the color- 
ation of the venter of the abdomen. This is variously marked, from the com- 
moner green to entirely brownish black.)

The species Chrysopa rufilabris varies considerably and many speci- 
mens do not exactly fit descriptions. There appears to be a gradation 
from rufilabris to interrupta. In these studies the specific name inter- 
rupta was applied to very light, ‘‘straw yellow’’ specimens, and 
rufilabris to the darker forms. The latter are by far the most abundant. 
It is not unlikely that these two species are in reality one, but the writer 
has not had sufficient material of interrupta for study to justify definite 
conclusions. 
C. rufilabris is widespread in its distribution. At Milwaukee, it 
was the most abundant species at lights. Specimens have been taken at 
Ithaca at lights, in woods, and in shaded goldenrod patches. At Char- 
lottesville they were most abundant in a dense grove of oak and pine. 
At Dayton, Ohio, they were taken in a goldenrod patch along a fence in 
an oculata habitat. The species is predominately, however, a woods 
species. 
Egg.—Elongate elliptical, very light green to faint yellowish green in color. 
Stalked, laid singly on leaves of maple and fruit trees, on grape, and on both 
trunk and leaves of oak. Length of egg, 0.88 mm.; greatest diameter, 0.48 mm.; 
length of stalk, 4.0 mm. 
First-instar larva.—Head very large, out of proportion to remainder of body; 
gray, with two broad, longitudinal, convergent, faded black bands on dorsum, 
arising inside of bases of antennae, and extending posteriorly the entire length 
of head. Antennae and palpi grayish translucent. First subsegment of pro- 
thorax translucent; second subsegment wholly translucent but with pinkish 
tinge; depressions prominent, dark brown to black. Next two thoracic segments
