724 FAMILY VIII. GRYLLID.E. THE CRICKETS. 



that the "song of nigricornis so closely resembles that of quadri- 

 punctatus that it is very dififcult to distinguish the two/' and 

 Allard (1911) says that he "has been unable to find any constant 

 differences which serve to distinguish the trills of these two 

 species." I therefore regard quadripunctatus as only a color va- 

 riety of nigricornis, gradually replacing the latter southward and 

 wholly so in Florida. In Indiana, as perhaps elsewhere as far as 

 can be judged from the records, the typical form nigricornis is 

 more abundant in the cooler and moister regions and the variety 

 in warmer and drier localities. 



The range of 0. n. quadripunctatus as given by Fulton is al- 

 most exactly that of nigricornis, Florida, Colorado and Utah be- 

 ing added to the list of states mentioned and California not given. 

 R. & H. (1916) record it from many localities from Virginia 

 south west ward to Ft. Myers, Fla., and state that it is "the most 

 abundant species of Oecantlius in the eastern United States." 

 Morse says that it is widely distributed and locally abundant in 

 southern New England and extends as far north as Brunswick, 

 Maine. Lugger recognized two forms of nigricornis as occurring 

 in Minnesota but evidently was not aware of Beutenmiiller's name 

 for the pale one. I once found it abundant on the north shore of 

 the Niagara River opposite Buffalo, N. Y., where it was the only 

 Ocean tli us seen in early September. Specimens are also at hand 

 from Sherboru, Mass., North Madison, Conn., Mobile, Ala. and 

 Agricultural College, Miss.

Delaware County, Penn., Sept. 29 (Hebard). Described from 

 Windham County, Conn, and ranges from Gloucester, Mass, west 

 to Bloomsburg, Pa. and southwest to Raleigh, N. Car. Hart 

 (1907, 235) has recorded it from northwestern Illinois but (Ms.) 

 reports that his specimens were not from pine and their identifi- 

 cation uncertain.
