November 2, 1893.—Mr. Heideman presented a design for a seal for the society, 
which was adopted. 
Prof. Riley presented some ‘‘ Remarks upon Belostoma” in which he gave a care- 
ful review of the synonymy of Belostoma americanum and Benacus griseus, indicating 
the structural differences between them based upon careful dissections. Discussed 
by Dr. Gill, Messrs. Schwarz, Ashmead, Heideman, and Howard. Prof. Riley read a 
second paper entitled ‘‘Remarks on the eggs of Ceresa” showing that his early 
figure of the egg punctures of a species which he called C. bubalus were in reality 
the punctures of C. taurina of Fitch, while the figure published by Marlatt and other 
western entomologists represents the true puncture of C. bubalus. Discussed by 
Mr. Ashmead, who pointed out the availability of the structure of the last ventral 
segment as a classificatory character in this genus. A discussion upon the use of 
the genitalia in classification followed, which was participated in by Drs. Gill | 
Stiles, and Riley and Messrs. Ashinead and Schwarz. Dr. Riley read a third paper — 
entitled “ Notes from ‘Sunbury’” in which he presented specimens of injury which 
conclusively showed that Chrysobothris femorata goes through allits transformations 
in less than a year and that Trochilium syringe passes from the egg to the adult in 
Washington in at least three months.

growth of some speciesof Laboulbeniaceae. 
Mr. Ashmead showed a Floridian specimen of the Fulgorid African genus Ampli- 
cotes and said that he was familiar with a case in which a hymenopterous genus

Mr. Heidemann exhibited a new genus and two new species of Capsidae found
