prothorax. Body similar to larva of C. lineaticornis. Some variation in amount 
of brownish and black areas, and also in size. Specimens seen apparently on 
the average a little smaller than C. lineaticornis.

Chrysopa lateralis Guér. 
Several adults of Chrysopa lateralis emerged from larvae sent to the 
writer from Florida. Unfortunately most of the larvae had spun 
cocoons by the time they arrived. But on comparing the old head 
eapsule with the larvae that were seen, it appeared reasonably certain 
that the larvae of C. lateralis are almost identical with the same instars 
of C. lineaticornis. The only characteristic observed to be different was 
in the head markings. C. lateralis apparently has the two pairs of 
dorsal convergent dark brown to black bands. The inner pair arise 
inside the bases of the antennae, quickly converge, and extend as two 
convergent bands to a little beyond the middle of the head. The bands 
are widest in the anterior region and gradually become very narrow at 
the posterior border. The outer pair arise between the eyes and the 
bases of the antennae, and extend in a broad curve to the prothorax, 
almost parallel to the inner pair. On the outside of each of these bands 
is a large brownish spot of less intensity, making the outer pair of bands 
appear like a large elongate spot. The other head and body features, 
as far as known, are the same as are given for C. lineaticornis. 
From one cocoon there emerged an adult which does not conform to 
any description yet seen, but it is close to C. lateralis. It differs in that 
the entire first segments of the antennae, and the antennal space on the 
head, are wholly bright red. But one specimen has yet been seen and 
there is some possibility that this is a variant.

1903 Chrysopa cockerelli. Banks, Trans. Amer. Ent. Soc., vol. 29, p. 154. 
About fifty larvae of the species Chrysopa cockerelli were first taken 
on the campus of the Kansas State Agricultural College on October 19, 
1921, and following days, on the trunks of maple, linden, and dogwood 
trees. Several specimens were taken crawling over alfalfa under these 
trees. These larvae were fed for a time on aphids in the laboratory, but 
none of them spun cocoons. The larvae were divided into lots and 
placed in different situations for wintering. The percentage of fatality
