480 ENTOMOLOGICAL NEWS. [Dec., 'll 



at the last meeting of the Feldman Social, on the destruction 

 of hickory trees at Ardmore, Penna., by a bark beetle and said 

 an illustrated article on the subject of the destruction of trees 

 of this species had appeared in the issue of "Country Life in 

 America," for October I5th. 



Mr. West exhibited speciments of Catocala, among them be- 

 ing the beautiful C. nivea from Japan ; also some Pierids in 

 Denton glass mounts. 



Mr. Rehn exhibited a specimen of Acrido.vena hewaniana, a 

 peculiar Locustid from the Cameroons, West Africa, and a 

 pair of Corycus abruptus, another Locustid, from tropical- 

 Africa. The latter species exhibits great sexual dimorphism, 

 the male tegmina being enormously inflated and modified into 

 sounding boards for the tympanum, while in the female the 

 tegmina are single, vertical and unmodified. 



Mr. E. T. Cresson, Jr., exhibited a specimen of Clanoncn- 

 rum (Diptera) which he determined as infumatum Becker, and 

 said it was curious that the species occurred in America as it 

 was identical with specimens described from Egypt under that 

 name. He gave a history of the genus, which was erected for 

 the Egyptian infumatum of Becker. A species from the Bal- 

 kan region has also been described by Strobl, and Czerny found 

 a form in Spain and suggests that they are all the same species. 

 The speaker coincided in this opinion, having found a repre- 

 sentative in Arizona and Southern California, which in every 

 respect agrees with Becker's description of infumatum. 



Dr. Calvert made a communication on Bromeliad insects 

 found in Costa Rica (published in the NEWS for November and 

 December) . 



Mr. C. T. Greene reported the capture of Trichopoda lan- 

 ipcs at Castle Rock, Penna. 



Mr. Andrew Gray Weeks, of Boston, presented some en- 

 gravings of the late W. H. Edwards and S. H. Scudder. 



The Curator reported that the work of removing the insects 

 to temporary quarters began yesterday, and that it would take 

 a week to remove everything in the entomological rooms. 



HENRY SKINNER, Recording Secretary.
