78 Journal New York Entomological Society. [Voi. xxx. 



Discussion followed by many members, in the course of which Mr. Davis 

 called attention to the faunal map prepared by Dr. John L. Leconte for the 

 Smithsonian Institution (1859) whereon is shown the marked change that 

 takes place in the fauna near the 100 meridian, and to Prof. Cyrus Thomas' 

 Notes on the Saltatorial Orthoptera of the Rocky Mountain Region, 1872, 

 where the statement is made that the eastern limit of the arid plains consti- 

 tutes a more rigid boundary to the Orthopterous fauna than the dividing 

 range of the Rocky Mountains. 



Mr. Davis exhibited " Some New Cicadas from Western North America " 

 contained in three boxes. The descriptions have been published in the 

 Journal. 



Mr. Davis also exhibited the Proc. Ent. Soc. B. C. 



Mr. J. W. Angell commented on the ease with which Cicadas are col- 

 lected early in the morning and upon a convenient axe for collecting pur- 

 poses. 



Meeting of April 5. 



A regular meeting of the New York Entomological Society was held at 

 8 P.M., April 5, 1 92 1, in the American Museum of Natural History, Pres. 

 John D. Sherman, Jr., in the chair, with 22 members and four visitors, in- 

 cluding Dr. W. L. Tower, and several ladies present. 



Mr. Frank Morton Jones delivered a lecture on " Food Plant Influence 

 on Insect Specialization as exhibited by Sarracenia and Exyra," illustrated 

 by lantern slides, original drawings, photographs and specimens from his 

 herbarium and entomological collection. 



The entire history of each species of pitcher plant and allied genera from 

 New Jersey south to Florida and westward to California was given from Mr. 

 Jones' personal experience ; and the adaptations in the species of Exyra in- 

 habiting them were traced with equal care through egg, larva, pupa and 

 adult; of the adults dozens of specimens were shown. 



After discussion by Messrs. Bird, Weiss, Notman, Davis and Dr. Bequaert, 

 a vote of thanks, on motion by Dr. Lutz, was unanimously given to Mr. Jones, 

 Dr. W. L. Tower, present as a visitor, spoke of Mr. Jones' lecture as a wel- 

 come contribution to our knowledge of the subject in its thorough statement 

 of the facts, though he thought there might be some difference of opinion in 

 their interpretation. 



Mr. Leng announced the lecture at the Staten Island Museum on April 

 i6th, by Dr. J. Chester Bradley, on his recent travels in South America. *
