 depressed. Ovipositor brown, straight, longer than the posterior fe- 

 mora and apically tapered somewhat abruptly, the lower margin 

 tapered slightly more than the upper. Length, elytra, $ , 6.5 m.m., 9 ,

Type. No. 12,747, U. S. Nat. Mus. 



Two males, two females, Tray Mountain, Towns Co., N. 

 Georgia (alt. 4,389 ft.) H. A. Allard, collector. 



This green little grasshopper superficially resembles Xiphi- 

 dion brevipenne and X. cnsifcr, but is amply distinct from 

 both these species. The collector, in whose honor the species 

 is named, contributes the following notes relative to the occur- 

 rence and song of the insect : 



"I first heard and captured specimens of this Xiphidion late 

 in September, in a sunny, grassy spot in the woods at Indian 

 Grave Gap, Towns County, North Georgia. A few days later 

 I found it in similar sunny, open situations on Tray and Blue 

 Mountains, in the immediate neighborhood of Indian Grave 

 Gap. 



"It prefers the low weeds and short grass, and was very 

 musical during the sunny hours of the day. Its song is strik- 

 ingly unlike the notes of Xiphidion fasciatum or Xiphidion 

 memorale, as no staccato notes whatever precede the more or 

 less prolonged lisping phrases. These phrases are soft, faint 

 and often greatly prolonged. In sound-quality, they recall to 

 mind the notes of Orchelimum minor. I did not find this Xiphi- 

 dion particularly common." 



EIGHT illustrated lectures on The Development and Significance of 

 Animal Societies were given by William M. Wheeler, Ph.D., Professor 

 of Economic Entomology, Harvard University, at the University of 

 Pennsylvania, last month.
