PHILADELPHIA, Dec. n, 1894. 



A stated meting of the Feldman Collecting Social was held this even- 

 ing at the re^J.-nce of Mr. H. W. Wenzel, 1509 S. Thirteenth Street. 

 Members present : Messrs. Seeber, Dr. Castle, Johnson, E. Wenzel, 

 Boerner, H. W. Wenzel, Fox and Schmitz. Honorary members : Prof. 

 John B. Smith and Dr. Henry Skinner; visitor, Mr. C. H. Roberts. 

 Meeting called to order at 9.30 P.M., vice-president Seeber presiding. 

 Mr. Roberts read the introduction to his paper on the genus Dineutes, 

 also exhibiting his collection of the same, together with a number of 

 sketches illustrating some of their characteristics, stating that his collec- 

 tion represented all the known species, also containing two new species, 

 nignora.ndhonrii. In concluding this interesting communication he said 

 the paper would be completed for publication very shortly. By request 

 he also explained his method of collecting Elmis. He used for the purpose 

 a piece of cheese cloth about 2x2 feet long, which is spread across the 

 stream, two ends of the cloth being weighted down, then disturbing the 

 bed of the stream a few feet above; this causes the Elmis to cling to the 

 cloth as they are washed down stream. To demonstrate the usefulness 

 of this plan he stated where he had, on one occasion, in agitating a space 

 of about three feet, noticed that they accumulated so rapidly that they 

 began to immediately wash off; he at one gathered up the cloth and began 

 counting them; when his count reached about 700 specimens he tired and 

 quit; this find occupied one and a half hours. Upon being questioned 

 regarding the number of species in a find, he stated they generally repre- 

 sented from three to five. This was followed by a discussion as to the 

 best method for freeing specimens from grease and retaining the color. 

 It was generally conceded that first immersing them in hot water and then 

 in gasoline had been generally found the most satisfactory. 



Mr. Fox made some remarks, accompanied by black-board sketches, 

 on the genus Crabro, on which he has been working, preparatory to 

 monographing the species. Firstly, Crabro may be divided into two sec- 

 tions or divisions, by the sculpture of the mesopleurae and the presence 

 or absence of a crest or ridge on the epimerum mesopleurahs. In the 

 first section the mesopleurae are simply punctured and their epimerum
