Mr. Graf read a paper on his observations of metamorphoses 

 among various orders. 



According to reports from various sources neither A. olym- 

 pia nor A. genutia were seen this season, altho' eagerly sought.

The Brooklyn Entomological Society met April 2, 1908, at 

 55 Stuyvesant ave., Brooklyn with President Pearsall presiding 

 and 18 members present. 



Mr. Geo. Franck spoke on "Insects Characteristic of the 

 Mountain Regions of New York with their relation to some 

 low land species." His material came mainly from Sullivan 

 County. At 800 feet altitude, Satyrus alope began to mingle 

 with intermediate forms. From 1500 feet alope was replaced 

 entirely by nephele. The two typical species never met but the 

 intermediates bred freely with the type forms which they en- 

 countered. Mr. Dow noted that at Claremont, N. H., only 

 alope occurred, the elevation being 900 to 1500 feet. Mr. Eng- 

 elhardt observed that at the base of the White Mountains, prob- 

 ably 3000 to 3500 feet, all Satyrus were nephele. 



Mr. Franck showed a long series of Argynnis from Sul- 

 livan County, cybele, grading into aphrodite and aphrodite into 

 alcestis, as altitude increased. His series of Basilarchia showed 

 no such gradations. Prof. J. B. Smith noted that at Del- 

 aware Water Gap arthemis and astyanax were found but pros- 

 erpina did not occur. Mr. Pearsall noted that at Big Indian 

 Valley, Catskills, where proserpina was plentiful, neither of the 

 others occurred. He claimed positively that proserpina was a 

 good species. Professor Smith admitted that at least in some 

 localities proserpina met perfectly the generally accepted de- 

 finition of a "species." Mr. Franck dissented and stated that 

 at least one of his female arthemis from Sullivan County could 

 not be distinguished from the type of the newly described 

 Basilarchia astyanax, variety albofasciata Newcomb. Members 

 of the society have an albofasciata 9 from Staten Island, and 

 a $ from New Brunswick, N. J., altitude in both cases being 

 less than 150 feet. Astyanax is a lowland species, arthemis 

 a mountain dweller. 



Mr. Dow claimed that a constant difference between the 

 two albofasciata seen by him and all the arthemis in many 

 long series was the presence in the former of the blue or green
