common than either niveus or fasciatus. A fully developed male was taken 

 from a leaf of an iron weed, Vernonia fasciculata Michx., on August 11th. 



This completes the list of Gryllidni so far known to have been taken in 

 the state. Other species undoubtedly occur, and it was a desire to awaken 

 an interi st in the family and so lead, if possible, to their discoverj% which, 

 in the main, prompted the preparation of the present paper. 



The species most likely to occur, but which have not, as yet, been noted 

 are: Tridactylus terminalis, Uhler; Tridactylus minutus, Scudder; CEcan- 

 thus latipennis, Riley ; (JEcanihus bipunctatus, De Geer, and one or two species 

 of Myrmecophila, which are the smallest crickets known. They resemble 

 closely the young of cockroaches and inhabit the nests of ants. The writer 

 will be pleased to receive specimens of Gryllidos and other Orlhoptera from 

 any part of the state, and will return the names of those sent to all who 

 may so desire.

Our present knowledge concerning the green triton, diemvctylus viri- 

 descens. By 0. P. Hay. 

 The green triton, or newt, Diemyclylus viridescens, has been before this 

 academy for discussion at a previous meeting. Since that time there have 

 been some accessions to our knowledge regarding it. This pretty and harm- 

 less newt probably inhabits all parts of the state, but I have n<.t found it 

 abundant anywhere, though no doubt it is plentiful in suitable localities.
