232 REPORT OF STATE GEOLOGIST, 



[)rostrate tree trunks, which were molding in decay and covered with 

 greenish lichens and moss. The yellowish and brownish fallen leaves 

 were everywhere scattered over the bed of the forest. Occasionally, 

 when the wind was not blowing, the author was able to mark the pres- 

 ence of Tettigids by the sound made as they jumped upon the dried 

 leaves." Morse says that "in New England this species prefers sedgy 

 meadow lands and swales on sandy soil occasionally flooded by rains 

 or freshets and perpetually moist. The bulk of my specimens were 

 taken on a boggy swamp which had been filled in witli sand, and on 

 which water stood more or less of the time."

Body of moderate size; color extremely variable; usually dark 



grayish, sometimes rusty brown or fuscous; often ornamented witli 



two or four irregular velvety brown spots on dorsal surface of pro- 



notum, more rarely a large whitish spot in front of these; the hind 



femora often with one or two white blotches on its outer 



face. Surface of pronotum and legs everywhere finely 



granulate; the posterior half of the pronotum usually 



rugose, with numerous short, oblique wrinkles or ridges. 



Vertex extending in front of eyes, somewhat rounded 



in front, its median carina projecting forward beyond 



the sides. Pronotum variable in length, in the long 



form less prolonged backward than in granulatus, its 



Tettix omaius dorsal frout margin truncate; the median carina dis- 



Lu crr"^ tinct but not as high as in granulatus. Inner wings 



fully developed, extending a little beyond the apex of 



pronotum. The form with pronotum and wings shorter is, as shown 



by the synonymy, the one formerly known as T. triangularis Scudd.
