Mr. Bischoff exhibited his collection on the genera Phytonomus and 

 Ceutorhynchus, calling attention especially to his capture of Phytoywmus 

 exitnius at Caldwell, N. J., where it was abundant on leaves of water dock. 

 He pointed out also how certain species of both genera were found only in 

 low ground and some that feed on plants of low growth cannot usually be 

 taken by sweeping as the net passes over such plants. 



Dr. Sturtevant exhibited living specimens of various species of Drosophila 

 with enlarged colored drawings of each and discussed the distribution espe- 

 cially of introduced species, saying in part : " There are many species of ani- 

 mals that are ' weed-like,' in that they are much commoner about houses or 

 stables than in woods or remote places. These forms are usually widely dis- 

 tributed, and are in general open to suspicion of being introduced species. In 

 the Dipterous genus Drosophila there are, in this region, seven such species. 

 Five of these {D. funebris, D. busckii, D. melanogaster, D. repleta, and an 

 undescribed species) are cosmopolitan or nearly so. Of these, D. funebris was 

 the only one known from this country to Loew, Say, Harris or Fitch. The 

 other four have probably been introduced since the time of these entomologists. 

 The earliest dates for this region and for the rest of the world with respect to 

 these five species were discussed, as throw-ing light on the possible sources 

 from which they might have come. The other two Nearctic ' weed-like ' 

 species, both undescribed, range from New England to South America, and 

 have probably been introduced from the American tropics. All these species 

 breed on fruit or on decaying vegetable material, s-o that they might easily have 

 been accidentally imported. In fact, there can be no doubt that some of 

 these, as well as at least four other species common in the tropics about 

 fruit, especially bananas, are constantly being imported.- The four last men- 

 tioned tropical species have never been taken in the northern states, though 

 two of them are established in southern Florida. Apparently they are unable 

 to thrive in a region where the winters are cold." 



Mr. Notman exhibited new species of Bembidion, found last summer in 

 the Adirondacks at elevated places near Mr. Marcy, describing especially the 

 beaver meadows in which he has collected and the characters of the new 

 species and their nearest allies. These descriptions will be printed in the 

 Journal. 



Mr. Fall, present as a visitor, referred to previous taxonomic work in the 

 genus Bembidion, and the danger of working from uniques or small series, 

 especially if previously described forms were not recognized. 



Mr. Davis and Dr. Bequaert referred to much successful taxonomy having 

 been done under such conditions. 



Mr. Davis read an interesting letter from our member, L. R. Reynolds, 

 now in Mexico, and Mr. Sherman spoke also of Mr. Reynolds' letters to him. 



Mr. Weiss distributed specimens of Rhipidandrus paradoxus, which he 

 had bred from fungus. 



Mr. Fall spoke briefly of the work he was doing in the genus Hydroporus.
