During 1914 chrysopids were particularly abundant. They were 
in fact the most common predatory species. The ‘‘stalked”’ eges 
were everywhere in evidence and the adults, which are nocturnal, 
rose in swarms from under the foliage as one brushed through the 
cotton rows. 
Chrysopa quadripunctata Burm.—This species is also fairly com- 
mon in the Southeast. It is most noticeable during July and August, 
and its larva doubtless contributes to the predatory work of Chrysopa 
rupfilabris. . 
Chrysopa oculata Say.—Aduits of this lacewing fly (fig. 12) have 
been reared from larve actively feeding on red spiders. It is not 
particularly common in South Carolina, however, and as a red 
spider enemy probably is not of primary importance. 
Chrysopa mgricornis Burm.—This species has been reared on a few 
occasions from larve col- 
lected on cotton infested 
withredspiders. Itsstatus 
is probably about the same 
as that of C. oculata.

Its attack is almost en- 
tirely confined to the eggs of the red spider, but an occasional mite is 
destroyed. The earliest seasonal record of occurrence is April 30, 1914. 
It is first seen usually about the early part of May and becomes abun- 
dant during the middle of May. Thisspecies does not usually reach its 
highest development until August, although a large amount of con- 
trol work is evident during July. Arthrocnodax is always to be seen 
during September, sometimes commonly in large mite colonies, but 
becomes rare in October, during which month usually only pup 
can be seen. This important predator has been collected in mite 
colonies at Chase City and Emporia, Va.; Charlotte, Wilmington, 
Laurinburg, and Buies, N. C.; Allendale, Anderson, Batesburg, 
Brownsville, John’s Island, Leesville, St. Matthews, and other 
points in South Carolina; Macon and Savannah, Ga.; Orlando, Fla.; 
Girard, Albertville, and Boaz, Ala.; and Tallulah and Mound, La.
