which appears worthy of some designation whether specific or varietal. 

 The measurements of these specimens are as follows: 



Length of body 16.5 mm., 15.5 mm., 20 mm., 18 mm. 



Length of tegmen 9 " 9.8 " 9 " 7.5 " 



Length of caudal femur 10 " 10.8 " 11 " 11.5 " 



Length of ovipositor 13 " 12.5 " 



The original measurements of this species for some reason are 

 erroneous, this being the case with all the species of Gryllus measured 

 in the same paper, 24 the dimensions being little more than half the 

 usual size of the forms. Allowance for this may cause the synony- 

 mizing with neglectus, of Blatchley's Gryllus amerieanus, the chief 

 diagnostic characters of which, when compared w r ith pennsylvanicus 

 and abbreviatus, were stated to be the slender build, short tegmina and 

 ovipositor. When compared with an authentic pair of amerieanus in 

 the Academy's collection the Mt. Pisgah individuals are slightly larger 

 but otherwise inseparable. 

 Gryllus rubens Scudder. 



This southern form is represented by a series of nine males and 

 fourteen females from Raleigh, taken on dates ranging from April 16 

 to June 21 and also on September 7 and 13, 1904, a single male from 

 Sulphur Springs taken June 5, a single male from Edenton, secured 

 August 20 and one female from New Berne taken August 24. 



There is a very great amount of individual variation in size in both 

 sexes, the proportions of thirteen females from Raleigh being as 

 follows :
