Tettigidea taken at or near Chapada which I was at first inclined to place 

 here. It differs from the female, however, in the less advanced ^'ertex, 

 the less prominent frontal costa and in having the pronotum both spined 

 n front and strongly attenuate behind. 



Tettigidea scudderi Bolivar. 



Tettigidea scudderi Bolivar, Ann. Soc. Ent. Belg., XXXI, 1887, 299.— Hancock, 

 Genera Insectorum, fasc. 48, 1906, 68. 



Habitat. — Upper Amazon. Not conta'ned in the collect'on made by 



H. H. Smith. 



Tettigidea nicaraguae brevis Hancock. 



Tettigidea nicaraguce brevis Hancock, Tettig. N. Am., 1906, 158. 



Habitat. — This form of T. nicaraguce occurs on the Atlantic side of 

 Costa Rica, where it is fairly common in suitable localities. It may con- 

 tinue southward into the adjoining parts of South America. 



Other species of the genus are evidently to be met with in the same 

 general region, because the present collection indicates that the genus is 

 equally common in both continents, where its representatives are dis- 

 tributed throughout the tropical and warmer parts of the temperate zones.

Tettigidea imperfecta Bruner, Journ. N. Y. Ent. Soc, XIV, 1906, 147. — Hancock^ 

 Genera Insectorum, fasc. 48, 1906, 68.

Tettigidea planus Hancock. 

 Tettigidea planus Hancock, Trans. Ent. Soc. Lond., Sept., 1907, 243-244. 



Habitat. — This species has been reported but once. It comes from 

 Paramba, Ecuador, and tends to show that representatives of the genus, 

 are to be found across the South American continent from the Andes 

 to the Atlantic. 



Tettigidea gracilicornis sp. no v. 



Comparatively robust with abbreviated pronotum and wings, but with 

 very long and slender antenna;. A species above the medium in size and 

 approaching Bafrachidea in the vertex and pronotal structures.
