Dr. Southwick moved that the President appoint a committee of two to 

 arrange for the care of these letters. The motion was carried and the 

 President appointed Dr. Southwick and Mr. Davis. 



Mr. George Frank read an account of " A Collecting Trip to Highland 

 Lake, Sullivan Co., N. Y." He gave an interesting description of the char- 

 acter of the country, which made it an ideal spot for the collector, and 

 mentioned in passing the species of Lepidoptera collected or observed by him 

 on the trip. 



Prof. John B. Smith, speaking on " The Geographical Distribution of 

 Insects in New Jersey," remarked that the local map drawn on the black- 

 board was a little too extended, as it took in certain sections not falling within 

 the fifty-mile zone. He exhibited two maps of New Jersey, one a relief map 

 on which he called attention to its chief features and the other showing in 

 color the six faunal regions which he mentioned, namely, the Appalachian, in 

 the extreme northwestern part, along the Delaware River ; the Highlands 

 region, just eastward of the former ; the Piedmont Plain region, fitting in 

 between the Highlands region and the coast, the region of red sandstone, 

 high, hilly and rolling; the Delaware Valley region, south of the latter and 

 running diagonally across the state, which is the richest entomologically and 

 in which no part of the red shale occurs ; the Maritime region, along the coast, 

 and the Pine Barrens, occupying the greater part of southern New Jersey. 

 This region is not so sharply marked as the former, since there are scattered 

 islands of pine barren in the Delaware River region, at Jamesburg and on 

 Staten Island. He referred to the significant fact that in these various 

 faunal regions certain insects differ in the number of broods. Thus the elm- 

 leaf beetle has only one brood in the Piedmont Plain region, while it is 

 two-brooded in the Delaware Valley district. The codling moth is two-brooded 

 in the Delaware Valley and Pine Barren regions, and usually single-brooded 

 in the others, with an occasional fragmentary second brood due to seasonal 

 or local difference. He remarked that no strictly boreal species of insects 

 occurred in the northern highlands of the state, which had an elevation up 

 to 2,000 feet, but in the cold swamps of the pine barrens a few boreal forms 

 had been found. He thought the maps would be helpful as some portion of 

 each one of the faunal regions came within the fifty-mile zone of New York 

 City. Dr. Smith presented the maps to the Society with the prediction that 

 at least 15,000 species of insects would be found to occur within the pre- 

 scribed limits. 



On motion of Dr. Southwick the Society accepted the maps with thanks 

 to Prof. Smith. 



Mr. Leng asked if Trechus chalybaus, a boreal species, had not been 

 taken in the cold swamps of the pine barrens. Prof. Smith stated that it had 

 been found near Milltown and South River in the roots of grasses along the 

 water courses. 



Mr. Davis referred to a boreal mouse and a boreal snake occurring in the 

 cold swamps of southern New Jersey.
