October 1, 1889.—Meeting at Brooklyn Institute. 16 persons present. Presi- 
dent Casey presiding. Messrs. H. S. Woodman, Julius E. Meyer, W. C. Wood and 
Rey. J. L, Zabriskie were elected members of the Entomojogical Department. Mr. 
Weeks stated the percentage of certain lepidopterous larvze destroyed by Zachina, so 
far as his experience went, to be about 66. Prof. Smith noted the remarkable spread 
this year of Phytonomus punctatus ; the reported localities in New Jersey in which 
the 17-year locust had appeared ; the increase of Stones hispidulus, upon clover 
roots, and the importation of a cattle fly, and also related his experience in collecting 
from the surface of water during the process of flooding a cranberry bog. Insects in 
great numbers of many species appeared where nothing was previously visible. 
Podurids covered the surface so densely that Staphylinide, Scydmenide, Pselaphide, 
Carabidae, Coccinellide, and other families were supported by them. A favorable 
wind finally blew the floating mass to an angle in the shore where it gathered in a 
heap and rendered collecting easy and profitabie. Mr. Palm expressed his opinion 
relative to collecting in Northern Germany. Dr. Zabriskie had observed Corixa at- 
tracted by light and entering the room through a window screen. Mr. Beutenmiiller 
had taken what he supposed to be Euphanessa meridiana, natural habitat Florida, 
and also described the difference between the larva of Cadlosamia angulifera and C. 
promethea. Capt. Casey gave blackboard illustrations showing the structural differ- 
ences of the secondary sexual characters of S¢enws and ELuaesthetus, a specimen of 
which latter Mr. Weeks exhibited. Prof. Smith commented upon the importance of 
sexual characters as a basis of determination, Adjournment.
