Doings of Societies. 



American Entomological Society. 



Meeting of June 14th, 1915, in the Academy of Natural Sciences 

 of Philadelphia. Nine persons present. Dr. Philip P. Calvert, Presi- 

 dent in the chair. 



General — Mr. Hornig related his experience with an insecticide 

 spraying compound called "No-Bug-Atal" which he said kills all kind 

 of insects and ticks instantly on contact. It appears to be harmless 

 to most animals, but to cats and rodents it is said to be fatal. In all 

 cases witnessed the spray proved successful. He also said the collect- 

 ing at AUoway, New Jersey, this year was relatively very poor when 

 compared with that of last year. Dr. Castle made some remarks on 

 his winter trip to Florida. The winter was unusually cold and dry, so 

 not much collecting was done until the rainy season started in Febru- 

 ary. He was then able to make some interesting captures. The ex- 

 tensive forest fires also destroyed some of his favorite collecting 

 places. His ground traps did not seem to give results and upon a 

 nocturnal investigation he discovered tBat toads were always on guard 

 at the edges of the traps. 



Diptera — Mr. Greene recorded the capture of Euparyphus tetras- 

 pelus Lw. at Roxborough, Penna. June 13th, 1915. This is the first 

 record for the State. 



Hymenoptera- Lewis H. Weld of Evanston, Illinois, presented the 

 types and galls of Callirhytis furnessae Weld and Synergus furnessana 

 Weld. 



Mr. Greene spoke of observing the males of Megarhyssa greenei 

 with their abdomens inserted in the holes made by Tremex. He took 

 tliem to be females ovipositing until upon investigation they proved 

 to be males. 



Odonata. — Dr. Calvert spoke on the relation of the caudal gills of 

 Odonate larvae to the development of intestinal tracheae, with special 

 reference to the genus Calopteryx. He also mentioned diatoms on 

 the legs of larvae of Thaumatoneura and quoted Prof. Mann, an 

 authority on diatoms, who considered that the possible transportation 

 of diatoms by aquatic insects would explain some puzzling cases of 

 distribution. Dr. Calvert also exhibited a method of mounting 

 Odonate larval exuviae on mica slides for ready examination. 



E. T. Cresson, Jr., Secy, pro tern.
