Doings of Societies. 



American Entomological Society. 



Meeting of June 12, 1916, in the Academy of Natural Sciences of 

 Philadelphia. Dr. Henry Skinner, President, in the chair; nine persons 

 present. 



Economic Entomology. Mr. Laurent exhibited some mounted 

 Marguerite plants from the hothouse of M. Rothe. at Mt. Airy. Phila- 

 delphia, May, 1916. showing the ravages of an insect which destroyed 

 hundreds of them. Dr. Skinner suggested that the first brood of potato 

 beetles (Lcptinotarsa) could be destroyed by removing them before 

 they oviposited rather than by the poisoning method and at less expense 

 and damage to the plant. Mr. E. T. Cresson, Jr., exhibited a box of 

 insects infested by a species of Phoridae (Diptera). 



A new code of by-laws was adopted and other business transacted. 



R. C. WILLIAMS, JR., Secretary. 



Entomological Section, Academy of Natural Sciences, Philadel- 

 phia. 



Meeting of May 25, 1916. Eleven persons present. Mr. Philip 

 Laurent, Director, presiding. 



Dr. Calvert read an extract from a letter from Dr. Ris, of Switzer- 

 land, complaining of the uncertainty in the delivery of mail matter 

 to and from Europe on account of the war. 



Lepidoptera. Dr. Skinner exhibited chrysalids of Mcgathymns 

 cofaqui and M. yuccac collected in the yucca of Florida. He spoke 

 on the possible abundance of these species when special attention is 

 given to their habitats. He said that this is no doubt the case with 

 many other apparently rare species. 



Orthoptera. Mr. Rehn commented on a recent paper reclassify- 

 ing the Orthoptera. Exception was taken to certain portions, par- 

 ticularly those referring to the "leaf-insects" or the genus Fhylliion. 

 He exhibited specimens of both sexes of species of this genus and 

 one of another genus of "walking sticks," Tropidoderus, which shows 

 a very great resemblance to the male sex of Phyllium. 



Diptera. Mr. Hornig commented on the scarcity of mosquito 

 larvae in and about Philadelphia. He said that the first brood had 

 emerged and noticed that the females are still carrying eggs. In the 

 discussion which followed it was the general opinion that this scarcity 

 of the second brood was due to the continued cool weather. 



Meeting of September 28, 1916. Nine persons present. Mr. Philip 

 f inrcnt. Director, presiding. 

 Mr. Greene and Mr. Rehn discussed the persistency with which
