SPRING NUMBER 59 
species of lady-beetles, the Convergent, the Blood Red, and the 
Twice-Stabbed Lady Beetles, were present in the order named as 
far as abundance is concerned. Syrphus fly larvae were numer- 
ous as well as the larvae of aphis lions and trash bugs. Mr. 
Beyer’s observations in Polk County show that the same is true 
there. But the little hymenopterous parasite that is often so 
effective in keeping down Aphis gossypii was not observed. A 
small brownish beetle, identified by W. S. Blatchley as Cyphon 
ag Blatch., is predaceous on this aphid. 
The factor which makes a recently introduced insect so destruc- 
tive is lack of enemies. This aphid has enemies. Just how effec- 
tive they will be in checking the infestation it is as yet too early 
to state. 
Mr. Beyer has taken up the study of this insect intensively, to 
work out its life history particularly with reference to its ene- 
mies, both insect and fungus. 
This aphid differs from A. gossypw in the large proportion of 
winged adults which are very active. These winged forms have 
a dark brown thorax and green abdomen. 
MEETINGS OF THE SOCIETY 
Feb. 28. The Society met in Science Hall, President Merrill in 
the chair. Members present, Bates, Berger, Gray, Merrill, 
Thone, Walker, and Watson. 
The paper of the evening on the Orthoptera of Florida was 
read by Mr. F. W. Walker and discussed by those present. Mr. 
Walker reported 210 species and varieties from Florida. The 
following are to be added to those recorded by Blatchley (1920) 
from the state :—Parcoblatta zebra Hebard, P. divisa, Hebard, 
Melanoplus querneus R. & H., Pterophylla camellifolia Fab., Neo- 
conocephalus palustris Blatch., Orchelimum minor Brunner, 
Conocephalus saltans (Scudder), Ocecanthus eaxclamationis 
Davis. A few additional species have been recorded from Thomas- 
ville and Billy’s Island, Ga., a few miles only from the Florida 
line, and doubtless occur within the state. Sixty-four of the 210 
species have been described since 1900. 
As in the case of other insects and plants the Orthoptera of 
the extreme southern part of the state differ radically from 
those of the northern part, being related to or identical with 
West Indian forms. Mr. Walker would draw the line thru Bre-
