The October meeting of the Newark Entomological Society 

 was held on the I3th of the month at the residence of Mr. 

 H. H. Brehme, the President in the chair, and eighteen mem- 

 bers present. A vote of thanks was tendered to Prof. J. B. 

 Smith and Messrs. E. J. Smith, of Natick, Mass., and C. F. 

 Harbison, of Dayton, Ohio, for contributions of separates and 

 other papers toward the formation of a new library. Mr. 

 Wm. J. Erhard, of Newark, was elected a member of the 

 Society. 



Mr. Otto Buchholz gave an interesting account of his ex- 

 tended trips to Southern California and Arizona during the 

 past summer. In California he found the territory so gener- 

 ally under cultivation that really good collecting ground for 

 Lepidoptera was difficult to find. In Arizona he located at 

 Prescott, in Yavapai County, an exceedingly rocky country, 

 and collected chiefly at an elevation of between six and seven 

 thousand feet altitude. In all between seven and eight thou- 

 sand specimens of Lepidoptera and three to four thousand 

 specimens of Coleoptera were collected, besides a lot of mis- 

 cellaneous insects, reptiles, and minerals. Most all of the 

 insect material was taken at light. Sugaring yielded small 

 results, though it had been persistently followed throughout 

 his stay. Collecting on tree-trunks was very poor, practically 

 nothing having been taken in this way, and he attributed the 

 cause to the insectivorous birds, the lizards, and a species of 

 mantid which he found very numerous. 



Mr. Buchholz also exhibited light- and dark-colored cocoons 

 of Hyperchiria pamina, the difference in shade being due to 

 environment at the time of spinning. Those larvce left to 

 spin up in leaves produced the usual brown cocoons, while 

 others of the same lot, on being transferred to a box contain- 

 ing bits of white paper at the time indications of spinning 

 were manifested, produced light-colored ones. The fact that
