Vol. XXJ] ENTOMOLOGICAL NEWS 429 



A meeting- of the Entomological Section of the Academy 

 of Natural Sciences of Philadelphia was held September 

 22nd, 1910. In the absence of the Director and Vice-Director, 

 Dr. Castle presided. Eleven persons were present. 



Mr. Haimbach gave a talk on some of his observations 

 while in Massachusetts this summer. He first exhibited a 

 few specimens of Perichymenobuis fntstcllns he captured and 

 made some remarks on its habits. He also exhibited a small 

 nest of the white face hornet (Vespa maculata] in which he 

 found a species of mud-dauber wasp, which Mr. Daecke 

 thought was there merely by accident. Mr. Haimbach then 

 gave an interesting account of his observation of the ravages 

 of the Gypsy and Brown-tail moths, remarking upon the 

 desolate appearance of the woods caused by these pests ; there 

 seemed to be no life of any kind except the caterpillar and 

 moths. One afternoon he noticed a hollow maple trunk which 

 was thickly lined inside with the moths, but next morning 

 they had all gone. He said he was fortunate to be there during 

 a great flight of the Brown-tail moth and gave an account of 

 the flight, also of the "brown tail itch" caused by the irritation 

 from the fine hair from these moths. A noticeable peculiarity 

 of the Brown-tail is that it hibernates in the larval state, while 

 the Gypsy moth hibernates in the egg state. He said he saw 

 the ravages of the four principal pests. Leopard, Gypsy, 

 Brown-tail-moths and Elm leaf beetle. 



Mr. llg exhibited a mount showing the life history of 

 Ateva aurea Mr. Daecke said that the species is more com- 

 mon west than here but he has collected it in New Jersey. 

 This was followed by discussions by some of the members 

 relative to the species. 



Dr. Calvert showed a male of Nenrocordulia yamaskancti- 

 sis Provancher, taken by Mr. Daecke at Perdix, near Harris- 

 burg, Pa., June 8, 1910, which is a new species for Pennsyl- 

 vania, it having been originally described from Quebec. 



Mr. Cresson exhibited some Dcnncstes larvae and images 

 taken from a leather works in Cainden, N. J., where it was 

 doing much damage to the hides. There were three species
