Mr. W. T. Davis exhibited two specimens of the southern moth Pygarctia 

 abdominalis Grote, from Lakehurst, N. J. One was taken on May 29, 1905, and 

 recorded in the proceedings of the Society for March 20, 1906. The other was col- 

 lected while sweeping low huckleberry bushes June 13, 1908. 



Society adjourned. 



Meeting of March, 16, 1909. 



Held at the American Museum of Natural History, with President C. W. I.eng 

 in the chair and eleven members present. 



Dr. C. L. Pollard invited the Society to participate in a joint meeting with the 

 Brooklyn Entomological Society as guests of the Staten Island Association of Arts 

 and Sciences on Saturday, May 8. The invitation was accepted and arrangements 

 for an afternoon field trip were left with the Outing Committee. 



Mr. Engelhardt proposed as an active member Dr. F. E. Lutz, of the American 

 Museum of Natural History. On motion of Mr. Angell the by-laws were suspended 

 and the secretary empowered to cast a single ballot for the election of Dr. Lutz. 



Mr. Engelhardt exhibited an interesting series of the Bella moths — Ulelheisa 

 bella and U. otnatrix. The former was represented by a selected number of speci- 

 mens from the eastern United States, showing extensive local variations, besides the 

 varieties known as hybrida and tertninalis. The variety venusta was represented by 

 examples from Jamaica, W. I., and Cuba. U. ornatrix was shown from Texas, 

 Guatemala and Porto Rico. While the specimens from Texas and Guatemala indi- 

 cate only a slight tendency to variation, those from Porto Rico were remarkable in 

 this respect. One series, beginning with a typical U. ornatrix was arranged to show 

 a gradual line of variations ending in a good example of U. bella. Another series 

 ended with a specimen indislmguishable from the European species U. pulchella. 

 All of the specimens from Porto Rico were collected in a sandy region near San 

 Juan during November and December, 1908. A discussion of climatic conditions as 

 a factor in producing variations followed. 



Mr. Wm. T. Davis exhibited a great number of oak-apple galls, Amthibolips 

 confluentus, which he had found on the ground under three different oak trees on 

 Staten Island, and which had been opened by squirrels for the larvre within. The 

 galls had been cut off of the trees by the squirrels and about one half of the outer 

 shell and spongy matter in each instance had been torn away to secure the desired 

 larvK. He also exhibited acorns, hickory and other nuts opened to secure larvae 

 rather than the kernel itself. 



Dr. R. C. Osburn exhibited a collection of over 500 Syrphidce collected by two 

 friends on the abandoned Hope Trail, British Columbia. One genus, Pyritis, de- 

 scribed by W. D. Hunter a few years ago, was better represented in the lot than in 

 all the other collections of the world combined. 



Mr. John J. Davis, field entomologist, Illinois, spoke of his economic work in 

 the vicinity of Chicago. He mentioned Callopisti-ia Jloridensis as a pest in green 

 houses. This has been reported hitherto only from Florida. Its larvre were bright 

 green while on the ferns, but when reared in a tin box were almost black. This was 

 attributed to the degree of moisture present. In this connection Dr. Lutz described
