The persons named were duly elected corresponding members. 
A new publication committee, consisting of Messrs. Marlatt, Banks, Howard, 
Schwarz, and Linell, was appointed by the President to take up the publication of 
the proceedings of the first six months of the current year. 
Dr. George Marx presented the first paper of the evening, entitled ‘‘ Remarks on 
two new publications on the Spiders of the United States, by N. Banks and Eugene _ 
Simon.” After some preliminary remarks he contrasted the two papers, which 
cover practically the same ground, and one of which—that of Mr. Banks—was based 
on literature now out of date and written without the aid of type specimens, while 
the other was based on fuller knowledge, better command of the literature, and an 
acquaintance with the types. He gave an account of the writings on this group of 
Arachnids and deplored the conditions which led to the publication of necessarily 
incomplete and inaccurate work. Discussed by Messrs. Gill and Riley. 
Mr, Otto Heidemann exhibited drawings of certain rare Capsids and pointed out 
some of the characters used by European authors to distinguish the species and gen- 
era in Capside and showed their applicability to American species, illustrating his 
remarks with some very careful and artistic drawings of rare Capside. He described 
also his method of making these drawings. Discussed by Messrs. Riley, Gill, and 
Heideman. 
Mr. Howard presented a brief note upon Chalcidid parasites of Bark-lice, basing 
his remarks upon a paper published in the Swedish language by Christopher Auri- 
villius in the Eniomologisk Tidskrift for 1888. Aurivillius coneludes that these 
parasites do not interfere seriously with the economy of the Coccide, claiming that 
the females are pierced so late in life that the egg-laying 1s not hindered, while the 
males, when parasitised, are destroyed. Mr. Howard said that this state of affairs 
was the exception, as bark-lice are attacked by Chalcidid parasites at all stages of 
growth, and when once infested development is immediately arrested. A glance 
through the collection of Coccide in the U. 8. National Museum easily proves this 
and shows that Aurivillius’s generalization must have beenmade upon a very insuf- 
ficient number of instances. Discussed by Prof. Riley and Mr. Ashmead, who fully 
indorsed Mr. Howard’s position. 
The society then adjourned to meet the first Thursday in October, 1892.
