NOTES ON TWO CONOCEPHALIDS. 



BY WM. T. DAVIS, NEW BRIGHTON, STATEN ISLAND, NEW YORK. 



The grasshopper, Conocephalus caudellianus, was described in the 

 Canadian Entomologist for August, 1905, from several males found at 

 Lakehurst, N. J., in Sept., 1903. Since that time additional specimens 

 have been collected in New Jersey at Lakehurst, Tuckerton and James- 

 burg. We, however, failed to find any females on these occasions, and it 

 was not until August, 1910, while at Cold Springs, Cape May Co., N. J., 

 that two female caudelliafius were found in the meadow along Bradley's 

 Run. The ovipositor is '}^t^ mm. in length, and comes even with the end 

 of the elytra. The hind femora are 28 mm. long. The fastigium in shape 

 and markings is like thai of the males described as above cited. 



The caudeilianus found at Tuckerton in September, 1907, were in a 

 rather dry field, and some of them, when disturbed, flew away to long 

 distances. Two flew several hundred feet and lit in cedar trees that 

 bordered the field. This is an unusual proceeding, for they generally seek 

 safety by dropping to the ground and hiding among the thick vegetation. 



In the Proceedings of the Entomological Society of Washington, 

 Vol. XII, p. 121, 1910, Mr. H. A. Allard compares the stridulations of 

 Conocephalus exiliscanoris Davis and C. bruneri Blatchley. Since de- 

 scx'\h'mg exilisca?i07-is in 1886, I have collected a great many specimens, 

 and find that the song varies considerably in loudness, according to the 

 age of the singer. Its volume is also dependent on temperature to some 

 extent. Furthermore, the insect gradually decreases in size as one travels 

 north, those from Cape May Co., N. J., being much larger than Long 

 Island specimens. From these facts I am inclined to think that bruneri 

 is a synonym of exiliscanoris, as has been suggested.
