TeUigidea trinitatis Bruner, Journ. N. Y. Ent. Soc, XIV, 1906, 147. — Hancock, 

 Genera Insectoruni, fasc. 48, 1906, 68. 



Habitat. — Island of Trinidad. 



If the Tetrix purpurascens oi Serville (Ann. Soc. Nat., XX, p. 291) proves 

 to be a Tettigidea it will be found to closely resemble the present species, 

 if it is not the same. It too comes from Trinidad. 



Tettigidea hancocki sp. no v. 



A large but slender insect with small head, coarsely rugose but glabrous 

 spicateand longly attenuate pronotumand slender hind femora, reminding 

 one at first glance of Tettigidea lateralis Say, and its near allies of North 

 America. 



Head of moderate size, the eyes rather prominent, vertex somewhat 

 but angulately advanced in front of the eyes, the occipital carinae or rugae 

 uniting with the oblique prominent lateral carinae of the front which reach 

 the eyes; frontal costa broad, not prominent, the upper extremity nearly 

 filling the longitudinal sulcus of the head between the eyes, sulcate from 

 a point a little above the ocelli; outer joints of the palpi gently spatulate, 

 not strongly or noticeably sulcate. Pronotum attenuate and uncinate, 

 the dorsum gently rounded, rugose, the median carina coarse but not 

 prominent, in no part arcuate, the prominent rugae tending to form one or 

 two longitudinal ridges on each side between and for some distance back 

 of the humeri. Hind femora adorned above and on outer face with 

 comparatively few but prominent smooth elevations. Hind tarsi long 

 and slender, the third joint noticeably longer than the first. Wings 

 greatly surpassing the tips of the hind femora and the apex of the pro- 

 notum. 



General color of the pronotum above brownish testaceous, at the sides 

 piceous; sides of abdomen, pleura and most of pectus fuscous, the latter 

 provided in the center and laterally with raised, roughened, leaf-like 

 testaceous patches. Legs without definite traces of annulation or macula- 

 tion, the abdomen and femora below and the tibiae becoming paler. 



Length of body. cT, 10.25 mm.; of pronotum, 1 1.5 mm.; to tip of wings, 

 15 mm., of hind femora, 6 mm. 



Habitat. — ^Corumba, Brazil, on highlands, a single male, collected in
