Bruner: Tropical American Tettigonoidea. 331 



Sonic of these vary considerably, both in color and size, from the 

 typical form as described by St^l. At present, however, they are 

 left without further study. 



Genus Pycnopalpa Serville. 

 Pycnopalpa Serville, Ins. Orth., p. 408 (1839). 

 Soria Walker, Cat. Derm. Salt. B. M., II, p. 363 (1869). 



This is a closely related tropical American genus represented by 

 two species. 



68. Pycnopalpa bicordata Serville. 



For synonymy see Kirby, Syn. Cat. Orth., II, p. 477 (1906). 



Habitat. — There are specimens of both sexes of this insect at hand. 

 They come from Rio de Janeiro, where they were taken by H. H. 

 Smith. 



Genus Diplophyllus Saussure. 



Diplophyllus Saussure, Rev. et Mag. Zool. (2), p. 202 (1859). 



Turpilia Sx.Ai, Recens. Orth., II, p. 16 (1874); Brunner, Monog. Phaneropt., pp. 

 29, 324 (1878); lb., Addit. Monog. Phaneropt., pp. 22, 176 (1891); Saussure et 

 PiCTET, Biol. Cent.-Amer., Orthop., I, p. 353 (1898); Kirby, Syn. Cat. Orthopt., 

 II, p. 478 (1906). 



The representatives of the present genus are for the most part found 

 in the tropical portions of the Americas. Already at least fifteen 

 species have been recognized. What appears to be an additional 

 species is now at hand. 



69. Diplophyllus insularis sp. nov. 



Related to opaciis Brunner and punctatiis Stal, from both of which 

 it differs in several respects. 



Eyes globose, quite prominent; fastigium of the vertex subacumi- 

 nate, profoundly sulcate. Pronotum subopaque, rather closely and 

 coarsely punctulate, the disc flat, gently narrowed anteriorly, the sides 

 distinctly carinated, but the carinae becoming less marked from behind 

 forward, the front margin straight, behind subangulately rounded; 

 lateral lobes much higher than long, the anterior margin roundly 

 emarginate. Tegmina subopaque, the hind margin nearly straight, 

 moderately broad. Anterior and middle femora spined beneath on 

 the front margin, the hind pair spined on both margins. Metasternal 

 lobes rather lengthily produced behind, their outer margin straight, 

 the inner margin rounded; mesosternal lobes triangular, acuminate. 

 Hind femora rather short. Ovipositor short, strongly bent upwards, 

 the apex subacuminate, the apical half crenulate on both margins.
