A new publication committee, consisting of Messrs. Marlatt, Banks, Howard, 

 Schwarz, and Liuell, was appointed by the President to take up the publication of 

 the proceedings of the fiist 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 on literature now out of date and written without the aid of type specimens, while 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 Euroi)ean authors to distinguish the species and gen- 

 era in Capsida$ and showed their applicability to American species, illustrating his 

 remarks with some very careful and artistic drawings of rareCapsida?. 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 Entomologisk Tidskrift for 1888. Aurivillius concludes that these 

 parasites do not interfere seriously with the economy of the Coccida», claiming that 

 the females are pierced so late in life that the egg-laying is 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 jiarasites at all stages of 

 growth, and when once infested development is immediately arrested. A glance 

 through the collection of Coccidie in the U. S. National Museum easily proves this 

 and shows that Aurivilliuss generalization must have been made 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. 



C. L. Marlatt, 



Recording Secretary pro tern.
