HANCOCK 5 



prosternum is specialized in a sternomentum (chin-piece); 

 the mesosternal plate is wider than long, the metasternum 

 strongly curved; there is no aroleum between the terminal 

 claws of the tarsi; the ninth and tenth tera:a of the abdomen 

 in both sexes are provided with a median longitudinal sulcus; 

 the subgenital plate of the male, viewed in profile, is conical 

 or triangular, the cerci conico-cylindrical and very small, the 

 supraanai plate lanceolate or triangular ; the female ovipositor 

 serrulate, with sharp diverging extremities. During the last 

 ecdysis in arriving at the adult stage, the elytra take their 

 position on either side of the body and the wings become 

 extended and folded under the pronotal process. 



DISTRIBUTION. 



The Tettigidje were divided by Bolivar into seven sec- 

 tions, none of which it is necessary to revise. Of this number 

 four subfamilies appear to be represented, namely: Clado- 

 notincB, Aletrodorince, Tcttigince, and BatracliidincB. Of the 

 Cladonotince, the remarkable leaf-like CJwriphyllnm, Walk., and 

 Phyllonotns, Hanc, are represented in the West Indies. Mem- 

 bers of these genera exemplify the highest type of protective 

 resemblance. Another genus, Tylotettix, Morse, comes from 

 Nicaragua. Of the Metrodori?i(e the following genera: Chiri- 

 quia, Morse, Otumba, Morse, and Platythonis, Morse, are from 

 Nicaragua. The TcttigincF are represented by eleven genera; 

 the first, Nomotcttix, Morse, is largely distributed in the north- 

 eastern United States, but appears as well in Kansas, Nebraska, 

 Illinois, and southward. The genus Tettix, Charp., is numer- 

 ously represented by various species covering the temperate 

 region, extending north, and two species appear in the south- 

 ern United States. This genus was formerly thought to be 

 represented by one species in South America, namely, T. 

 aspcrulns, Bol., but this species appears to come under the 

 genus Apotettix, Hanc. Ncotcttix, Hanc, is essentially a south- 

 ern genus. Micronotiis, Hanc, as we have already mentioned, 

 is from the West Indies. Apotettix, Hanc, appears in Mexico 

 and Texas. The genus Oclietotettix , Morse, is Mexican. The
