Scudder.] 80 [March 7, 



General Meeting. March 7, 1877. 



The President, Mr. T. T. Bouve, in the chair. Forty-one 

 persons present. 



Messrs. L. L. Dame, Henry A. Holden, Allen Sullivant, 

 Charles E. Swett, Rev. G. F. Wright, and Miss Jane Alexan- 

 der were elected Associate Members. 



Dr. B. Joy Jeffries gave an account of the theory of color 

 blindness, and the practical relations of the subject, and his 

 remarks were illustrated with diagrams and experiments. 



The following papers were read : 



The Florida Orthoptera collected by Mr. J. H. Com- 

 stock:. By Samuel H. Scudder. 



As no attempt has yet been made to tabulate the Orthoptera from 

 any district in the southern United States, it has seemed desirable, in 

 naming for Mr. Comstock the species collected by him in the spring 

 of 1876, to print a list of them, with descriptions of those which 

 prove to be new. The collection was made almost entirely at two 

 localities — Jacksonville on the St. Johns, and Fort Reed in Orange 

 Co., about three miles south of Mellon ville, at the head of naviga- 

 tion on the St. Johns. So far as I am aware, no collections of any 

 importance have before been brought from the upper St. Johns, so 

 that this portion of the collection, and the larger one, has more than 

 ordinary interest. A few notes sent me by Mr. Comstock are ap- 

 pended under the species to which they refer; and occasional notices 

 of captures by others in other parts of the State, or of neighboring 

 States, are added. The Collection is in the Museum of Cornell 

 University. 



Gryllides. 



Gryllus assimilis (Fabr.) Goeze. H, 1 ?, found under 

 boards on the beach near Sanford, April 6 ; 1 ? , Ft. Heed, April 

 21 ; 1 $, Jacksonville, May 6. This agrees altogether with Saus- 

 sure's description of the small black United States form of the spe- 

 cies, excepting that the wings extend no further back than the tips 

 of the cerci.
