238 ENTOMOLOGICAL NEWS [May, 'll 



Meeting of March 23, 1911. Mr. Philip Laurent, Director, 

 presiding; fifteen persons present; Mr. Nathan Banks, of 

 Washington, D. C., visitor. 



Mr. Banks said he came to Philadelphia to study some 

 Hymenoptera in the Cresson collection. He was pleased to 

 meet the members and would like to have a collecting trip with 

 them in this locality and would also gladly exchange specimens. 



Mr. Rehn exhibited specimens illustrating the variability in 

 structural and color characters found by him in the Acridiid 

 Eritetti.v simplex. One hundred and forty-eight specimens from 

 Sulphur Springs, North Carolina, were the basis of his work. 

 The supplementary carinae of the pronotum were found 

 strongly or faintly indicated or lacking, while two marked, dom- 

 inant, color phases were found, connected by a number of 

 intermediates. The same speaker also exhibited the type of a 

 remarkable new genus and species of African Mantidae. 



Dr. Skinner exhibited a large series of Lycaena enoptcs, 

 battoides and glancon. He considered them variants of one 

 species. 



Dr. Calvert gave a very interesting description of the coun- 

 try on the Pacific side of Costa Rica. There are no railroads 

 in the province of Guanacaste, and in the wet season it is prac- 

 tically untraversable. While sleeping in a school house at 

 Santa Cruz, he had been bitten by an insect and in the morn- 

 ings found two specimens of a Conorhlnus (which were ex- 

 hibited), and attributed the bites to them. 



Mr. Banks referred to the severe disease carried to man from 

 monkeys by these insects in Brazil. 



Mr. Laurent stated that some lepidopterists were under the 

 impression that Danais plc.rippus was three-brooded in the 

 State of New Jersey, which the speaker said was a mistake, 

 and that he was sure that no species of Rhopalocera or butter- 

 fly, found in New Jersey, unless it was Pieris rapae or Lycaena 

 pseudargiolus, was more than two-brooded, and that a number 

 of species were represented by only one brood in a season, as 

 for instance Pamplnla metea, pontiac, leonardus, etc. The
