228 HEMIPTERA-HOMOPTERA. 
2. Oncometopia rufipennis, 
Tettigonia rufipennis, Sign, Ann. Soc. Ent. Fr. 1855, p. 797°. 
Hab. Mexico (Mus. Berol.'). 
I have not seen a specimen of this insect, which differs from the preceding species, 
according to Signoret, in being considerably smaller (length 14, as against 18 millim.), 
and in having the tegmina entirely reddish-hyaline and margined with yellow; the 
tegmina, moreover, are smoother, and not rugose as in O. rubiginosa. 
8. Oncometopia interjecta, sp.n. (Tab. XIV. fig. 12.) 
Oblonga, parallela, fusco-brunnea, tegminibus nigris, apicibus late hyalinis ; capite equilateraliter triangulari, 
vertice obtuso, oculis sat prominentibus ; pronoto nitido, leviter transversim rugoso; tegminibus remotius 
et rugosius punctatis, venis crassis, elevatis ; corpore subtus pedibusque fusco-violaceis. 
Oblong, parallel, the head and pronotum fuscous-brown, the tegmina black, with the apex broadly and clearly 
hyaline ; head equilaterally triangular, with the vertical angle obtuse, rounded ; pronotum shining, finely 
rugose; scutellum large, fuscous or variegated with testaceous; tegmina rather sparingly and strongly 
punctured, with thick raised veins; underside and legs of a fusco-violaceous colour, the latter darker, 
sometimes nearly black; last ventral segment of the female emarginate, with the side-lobes short. 
Long. 12 millim.; lat. ad hum. 3 millim. 
Hab. Panama, Bugaba (Champion). 
This species, at first sight, appears to be allied to Phera vitripennis, but it has a 
much shorter head. Although the head is longer and more triangular than is usual in 
Oncometopia, the insect possesses all the other characteristics of the present genus; it 
may, perhaps, be regarded as a connecting-link between Phera and Oncometopia.

Tettigonia herpes, Sign. Ann. Soc. Ent. Fr. 1855, p. 796°. 
Hab. Norra America, Nova Scotia‘, Florida*_—Mexico (Sallé, Mus. Vind. Ces.), 
Cuesta de Misantla, Jalapa (I. Trujillo), Atoyac in Vera Cruz (H. H. Smith), Orizaba 
(H. H. Smith & F. D. Godman), Teapa in Tabasco (H. H. Smith), Oaxaca (Mus. Brit.) ;

This seems to be a very widely distributed insect ; it varies considerably in size, but 
intermediate forms occur. The head and pronotum are often of a lighter colour than 
the tegmina, and in some cases (7. herpes, Sign.) there are a few minute light spots 
sprinkled over the tegmina.
