Tue BIoLoGy oF THE CHRYSOPIDAE 1361 
(This larva resembles that of C. rufilabris except that the latter is lighter 
red in color and its color is more nearly solid. Also the lateral tubercles are 
smaller in C. rujilabris. C. plorabunda differs from C. oculata in its head mark- 
ings and in having a complete gray or yellowish gray border to the body.) 
Pupa.—Cocoon of white silk, somewhat transparent, almost as much so as in 
C. rufilabris. Length of cocoon, 3 mm.; diameter, 2.75 mm. (Pupae have head 
and body markings of adult to a large extent.) 
Adult.—One of the most beautiful of our lacewings. Body yellowish green 
(chromium green); head somewhat more yellowish; a prominent greenish 
yellow (primrose yellow) stripe from head to end of abdomen; wings wholly 
green; a shining narrow band of reddish black from each eye to mouth; labrum 
and borders of dark band distinctly reddish. 
(This species is distinct, but there appears to be almost a gradation to 
C. harris, C. rufilabris, and others closely related.) 
Chrysopa sp. 
While sweeping goldenrod and asters, and in the Renwick marshes 
at Ithaca, the writer found two specimens of a gray larva. For some 
reason they failed to spin but curled up on the bottom of the vial. Ina 
short time both were dead, and so the species is unknown. Since the 
larva is so distinctive, however, a brief description is included here. 
Only the third-instar larva was seen. It apparently belongs in the 
quadripunctata group. 
Third-instar larva(Plate LXXXIV, 2).—Predominately gray. Head with four 
elongate black bands on dorsum, converging but not curved, inner pair about 
half as long and wide as outer pair. Prothorax largely gray; lateral tubercles 
small, wholly gray. Mesothorax with dark brown to blackish bands on each side 
of dorsal vessel, extending from prothorax to posterior part of metathorax and 
forming a saddle-shaped marking. Abdomen wholly gray, somewhat marked 
with brown or blackish along sutures; first segment without definite lateral 
tubercles; segments 2 to 5 alike, largely gray, marked with brown in middle 
and at each side; segments 6’to 8 darker, with prominent brown patches on 
each side of vessel; segments 9 and 10 still darker; all lateral tubercles 
relatively small and wholly gray, stalks short.

Larvae of Chrysopa lineaticornis have been taken at Ithaca, where 
they were found on the lower branches and leaves of a linden in a 
densely shaded locality on August 27, 1916, and following days. Larvae 
were found also on underbrush near the linden. At Charlottesville, 
Virginia, they were taken many times during the summers of 1918 and 
1919, mostly on the underbrush in woods, on honeysuckle vines, and on
