surrounded by more than a score of primary and secondary parasites, 

 scavengers and depredators, as well as attacking mammals, bacterial and 

 fungus diseases. He also showed the value such data would have in eco- 

 nomic lines, in deducting to what per cent, a given parasite might be ex- 

 pected to control its host. His remarks were illustrated by specimens of the 

 host and parasites and by blackboard diagrams. 



Dr. Bequaert compared his experiences in " Collecting Flies on Three Con- 

 tinents " referring esp'ecially to his collections in Belgium, in northern 

 Africa and at Lahaway, Lakehurst, Ramsey, N. J., and Chittenden, Vt. He 

 said that on account of the Diptera being especially northern in distribution, 

 the result showed a smaller number of species for New Jersey than for 

 Belgium as was to be expected; but it also showed the presence in New 

 Jersey of certain southern genera, unknown in Belgium, as well as the 

 absence of some exclusively old world genera. Six boxes of specimens were 

 shown and the illustrations, requiring use of lantern were reserved for next 

 meeting. Dr. Bequaert spoke earnestly of the advantages of the personal con- 

 tact with nature derived from field collecting in pursuing any studies in natural 

 history. 



Mr. Woodruff, after reporting his visit to Mr. Sleight's home in Paterson, 

 where he found him still very ill and emaciated, but sanguine and looking 

 forward to an early removal to Lake Hopatcong, exhibited Schistocerca 

 peregrina the biblical " locust " described by Mr. Dow at the last meeting. 



Mr. J. W. Angell exhibited some rare Lucanidae, viz. : Dorcus brevis Say, 

 found some years ago by Gustav Beyer near the roots of an old pine at 

 Newport News, Va., in June ; Pseudolucanns placidus Say, labeled Green- 

 wood Lake, N. J. ; Dorcus parallelopipedus Linn., two specimens from F. 

 Emille, Longueuil, Canada, apparently confirming the North American record 

 given by Nonfried ; Liicaiius elaphus var. carlengi Angell, now known from 

 Texas, Kentucl<y, Illinois ; Necrophorus grandior Angell and mysticollis Angell, 

 new species recently described in Entomological News ; Diphyllostoma nigri- 

 collis Fall, and Cyclommatus imperator Boileau, from New Guinea, the largest 

 Species of the genus. 



Mr. Davis exhibited a living Neoconocephalus triops Linn, found by Mr. 

 Comstock in a head of lettuce in which it had undoubtedly traveled from its 

 home in the southern states. 



The President announced the death of Dr. R. E. Call. 



Dr. Bequaert exhibited a huge volume on Hymenoptera, just published in 

 the Guide to Insects of Connecticut, with two similar European works for 

 comparison, praising highly the Connecticut book. 



Mr. Mutchler exhibited for Mr. Bird, Megarhyssa atrata Fabricius, in its 

 characteristic pose ovipositing in the larval burrow of Tremex columba, of 

 which it is a parasite.
