jNIr. Aaron, from the special committee, reported that the rooms

The following donations to the cabinet of the American Entomo-

Pamphila nrsa and several small Neuroptera from Mr. Calvert. 



Written communications 228-229-230 were read by title and re- 

 ferred to the Publication Committee. 



Dr. Horn announced that the Transactions to page 350 had 

 been completed, with seven plates, to which the Proceedings would 

 add probably thirty pages. 



Prof. J. B. Smith stated that while at Anglesea, on the sea-coast, 

 he noticed a series of contests. First there were enormous swarms 

 of mosquitos, soon after large numbers of Dragon-flies appeared and 

 fed rapaciously on the mosquitos. Later in the afternoon flocks of 

 sea-gulls appeai'ed, in their turn devouring the Dragon -flies ; the 

 battle continued until dark, when the gulls and Dragon-flies disap- 

 peared, leaving the mosquitos apparently none the less numerous. 

 He observed that mosquitos lived abundantly in the woods as well 

 as in the clear and open spaces, by which means they escaped the 

 Dragon -flies, who avoided the forests. 



Dr. Horn spoke of the genera allied to Philydrus, and illustrated 

 especially the forms of claws in the male. 



Mr. Westcott recorded the capture of Pamphila viator at Wood- 

 land Beach, also P. Delaware at Manayunk, the latter being a very 

 rare occurrence so far north. 



Mr. Aaron reported that Pamphila fusca had become abundant 

 near the city by the introduction of its food plant from the South. 



Mr. Wells reported the capture of Catocala rector at Cresson, Pa.
