PROCEEDINGS OF MEETINGS. 



March 22, 1894. 



A regular stated meeting of the Entomological Section of the Academy 

 of Natural Sciences was held in the Hall, S. W. cor. Nineteenth and Race 

 Streets, this evening, Dr. Geo. H. Horn, Director, presiding. Members 

 present: E. T. Cresson, G. B. Cresson, Calvert, Ridings, Laurent, Skinner, 

 Johnson and Liebeck. Associate: Fox. Dr. Skinner explained a method 

 of dissolving grease from specimens. Instead of wedging a piece of cork 

 in the bottom of a jar or glass, the insect is pinned on a piece of sheet 

 cork and the cork then floated with the insect downward in the gasoline 

 or other liquid used. Dr. Horn described a similar method. Mr. Calvert 

 said that benzine dissolved the powdery substance found on dragonflies, 

 and that alcohol did not, so that he preferred the latter for some speci- 

 mens. Dr. Horn exhibited a photographic negative of a curious beetle 

 from Lower California, which he had recognized as probably new. He 

 afterwards found that it had been described by Bates as a Longicorn, but 

 belongs to the Rhipiceridse, and is known as Vesperoctenus Jlohri Bates. 

 Mr. Fox called attention to a bee of the genus Oxaa from Lower Cali- 

 fornia. He stated that the genus Oxcea had been heretofore restricted 

 to South America, and that the species exhibited, which was new, was 

 most closely related to an undescribed form from Brazil. But three spe- 

 cies of the genus had been described, and none had been described since 

 1865. Henry Skinner, Reccn-der.
