and larger Heterocera, comparing the present rarity of some 

 of the species around Newark with their comparative abund- 

 ance in past years. This lie attributed in a measure to the 

 encroachments of the expanding city upon the breeding- 

 grounds, but also to parasitism and disease to which many 

 species seemed especially subject in late years. In closing his 

 paper, Mr. Brehme called attention to the advisability of trans- 

 ferring the better species to new fields. 



In reference to this latter statement Professor Smith said 

 that considerable work of this character is being done in Eng- 

 land with good results. 



Mr. Doll spoke of the difficulties sometimes attendant upon 

 the transference of insects from one place to another and said 

 that all his attempts to establish Philosamia cynthia in new lo- 

 calities were absolute failures, due probably to the larvae fall-

lands. Limacodids are being literally banished from large 

 sections of territory lying adjacent to cities, and such species 

 as Ecpanthcria dciiorata, once so common, are now being re- 

 duced almost to extinction by this same cause. 



A meeting of the Newark Entomological Society was held 

 April n, 1909, in Turn Hall with the President in the chair 

 and twenty-three members present. 



Mr. John Kuenzler, of Paterson, was elected to membership. 



Mr. Buchholz stated that Philosamia cynthia cocoons were 

 this year generally parasitized by a species of Piinpla. 



Prof. Wormsbacher reported Feralia jocosa unusually abund- 

 ant at Alpine, N. J. 



Succeeding these reports Professor Smith gave a lecture 

 on Mosquitoes, illustrated with lantern slides. He outlined the 

 work that is being done in New Jersey and gave a history of 

 the development of the methods now in use in ditching marsh- 

 lands. The work of extermination in New Jersey is progress- 

 ing as rapidly as the limited funds appropriated by the Legis- 

 lature will permit. Already 25,192 acres of salt marsh have
