The haunts and habits of these had previously been unknown 

 to the speaker and a number of the species were new to the 

 New Jersey fauna. The smallest Scydmenid and the smallest 

 Pselpahid were also shown. The saline fauna was said to 

 differ very greatly from the near-by fresh-water ponds. The 

 same speaker also exhibited a fine specimen of Panagceus 

 ^rucigerus and stated that another specimen had been taken at 

 Anglesea by his son. The dates were April i6th and May 

 20th, on loose sand. Mr. Lieback stated that the specimens 

 previously taken by the late Dr. John Hamilton at Brigantine 

 Beach were found under pieces of caked sand. Mr. Laurent 

 read an interesting paper, giving the itinerary of his last Sum- 

 mer's' collecting trip to Colorado and Utah in company with 

 Henry Skinner and A. J. Snyder. Mr. Wenzel presented an 

 interesting and valuable letter to the society. It was an invi- 

 tation to his grandfather, Henry Feldman, to attend the 

 organization meeting of the Entomological Society of Phila- 

 delphia in 1859. On motion of Mr. Fox a vote of thanks was 

 tendered to Mr. Wenzel for his gift to the .society. 



Dr. Henry Skinner, Secretary. 



At the last meeting of the Feldman Collecting Social, held 

 April 18, 1900, at the residence of H. W. Wenzel, 1523 S. 13th 

 Street, ten persons were present. 



Dr. Skinner referred to some Cecropia cocoons recently col- 

 lected by Mr. H. W. Wenzel. One specimen had inside of the 

 inner cocoon specimens of the chrysalis of a moth. He be- 

 lieved it likely that the female moth had oviposited on the out- 

 side of the cocoon and the young penetrated after birth. 



He referred to a recent discussion as to the cause of the 

 size of certain Cecropia cocoons and pointed out that the 

 thick cocoons are those of females and the thinner ones males. 

 This he had proven by segregation of the robust and slender 

 cocoons. 



Dr. Strecker corroborated Dr. Skinner on this point, as he 

 had had similar experience with these cocoons. 



The question was further discussed by Messrs. Smith, 

 Strecker and Skinner.
