ENTOMOLOGICAL SOCIETY OF WASHINGTON. 
October 5, 1893. — Mr. R. S. Lull, of the Maryland Agricultural College, was elected 
an active member. Messrs. W. D. Doan, of Coatesville, Pa. ; J. L. Healey, of Rogers 
Park, 111.; H. C. Fall, of Pomona, Cal. ; H. F. Wickham, of Iowa City, Iowa; and 
L. W. Mengel, of Lancaster, Pa., were elected corresponding members. 
Mr. Schwarz gave some additions to the list of North American termitophilous and 
myrmecophilous Coleoptera. Discussed by Messrs. Riley and Schwarz. 
Mr. Marlatt read a paper on the neuration of the wings of Tenthredinidae, pro- 
posing a system of nomenclature of the veins, following closely that of Cameron 
and Andre, with a few minor changes. Discussed by Messrs. Ashmead, Riley, and 
Howard. 
Mr. Hopkins presented some short notes upon certain wood-boring beetles, exhib- 
iting drawings of the species. Tbo forms mentioned were Hylecoetus lugubris from 
chestnut, Serropalpus striatus from black spruce, and Eupsalis minuta from oak, and 
an unknown Coleopterous larva injuring oak and chestnut. Discussed by Messrs. 
Schwarz and Riley. 
C. L. Marlatt, 
Recording Secretary, 
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. Ashmead and Schwarz. Dr. Riley read a third paper 
entitled "Notes from ' Sunbury'" in which he presented specimens of injury which 
conclusively showed that Chrysobofhris femorata goes through all its transformations 
in less than a year and that Trochilium syringes passes from the egg to the adult in 
Washington in at least three months. 
Mr. Schwarz exhibited a Pterostichus the elytra of which were covered with a 
growth of some species of 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 
occurs both in Africa and in Florida, but not elsewhere. 
Mr. Schwarz stated that the Halticid genus Argopistes has this same distribution. 
Mr. Heidemann exhibited a new genus and two new species of Capsidae found 
near Washington. 
Dr. Gill exhibited the cocoon of a species of Phydippus found in a bunch of grapes.
