sects could be gleaned from the study of this organ, and also 

 to learn the changes which it undergoes during the course of 

 individual development. Some details of the results were 

 given. A paper has been completed which, it is hoped, will 

 be shortly published. Mr. W. R. Reinick was elected a mem- 

 ber of the Societ3^ 



Henry Skinner, Secretary. 



At the September meeting of the Feldman Collecting Social, 

 held at the residence of Mr. H. W. Wenzel, 1523 South 13th 

 Street, fourteen persons were present. 



Dr. Castle exhibited a specimen of Cychrus viduus taken at 

 Hope, N. Y. 



Mr. H. W. Wenzel referred to a forthcoming list by Mr. 

 Leng on the Cicindelidae of the Upper Pine Barrens of New 

 Jersey, in which several rare species will be recorded, includ-

The occurrence of Cicindela kpida in Ocean County was

 attempted to eat their way through a cork to escape from a 

 bottle. Specimens of E. marginata similarly confined made no 

 effort to escape. He also showed hickory twigs which had 

 been severed by an Agrilus larva, the marks left by the larva 

 being in the form of a spiral. A letter from a correspondent 

 in Hunterton Co., N. J., on the destructive properties of the 

 larva of the Catalpa sphinx was read. The species had not 

 been before recorded from New Jersey. 



Dr. Skinner stated he had received a specimen of this larva 

 from Lisette, Pa. He believed its recent spread into the 

 North is due to the many catalpa trees that had been cultiva- 

 ted in late years, owing to the belief that this tree is free from 

 pests. He also referred to the use of formalin as a preserva- 

 tive, and stated that he believed the formalin might set the
