TETTIGINAE. 



Nomotettix Cfistatus Scudder. 

 Georgia: Sand Mountain (juv.). 

 Alabama: Lookout Mountain (juv.)' 

 Arkansas: Dardanelle (Mena, juv.). 



Nomotettix cristattts denticulatus Morse. 



Nomotettix crestatus denticulatus* Psyche, xui, 119, 1906. 



Indian Territory: Caddo (juv.); Haileyville; South McAlester (juv.). 

 Texas: Denison. 



The variety denticulatus is distinguished by being more scabrous 

 than the type form, with the margins of the pronotum very minutely 

 serrulate, the sides of the vertex of the head less regularly convex, its 

 carina less protuberant, the carina of the pronotum thinner and higher, 

 the middle femora with undulate margins, and the upper edges of the 

 hind femora with inwardly or upwardly directed denticulate projec- 

 tions. These characters are exhibited by a male from Denison, and 

 the specimens from Indian Territory show them in lesser degree. All 

 of the examples secured have a more elevated and thinner carina than 

 New England specimens, approaching the compressus form. 



This species is not uncommon locally on damp, sandy loam, thinly 

 grassed or more or less exposed to light and sun, such as upland 

 pastures at the North or the edges and openings of woods at the 

 South. In summer the young are numerous, the adults very scarce.

One of the most plentiful species of Tettiginse in the southeastern 

 quarter of the country, often occurring in great abundance in specially 

 favorable localities. Such a spot is shown in the frontispiece in the 

 flat piney- woods of southwestern Arkansas. It is widely and rather 

 generally distributed, preferring sandy soils which are frequently or 

 perpetually moist. Both long- winged and short-winged forms were 

 obtained, the latter being somewhat more plentiful.
