Bruner: Tropical American Tettigonoidea. 335 



Genus Philopiiyllia Stal. 



Philophyllia StAl, Recens. Orth., 2, p. 18 (1874); Brunner, Monog. Phaneropt., 

 p. 349 (1878). 



The representatives of this small genus are confined, so far as 

 known, to southern Mexico and Central and South America. Three 

 species have been described. Only one of these is at hand. 



78. Philophyllia venosa Brunner. 



Philophyllia venosa Brunner, Monog. Phaneropt., p. 351 (1878). 



The material collected by H. H. Smith at Rio de Janeiro contains a 

 pair of this species. The male agrees with Brunner's description in 

 every respect so far as given. The hind femora are 22 mm. in length. 

 The female has the following dimensions: Length of body, 23 mm., of 

 pronotum, 5.15 mm., of tegmina, 38 mm., width, 10 mm., length of 

 hind femora, 24 mm., of ovipositor 5 mm. At first I was inclined to 

 place the female in the genus Orophus on account of the structure of 

 the ovipositor, which does not agree with the description of that 

 organ for the genus (see generic synopsis section dd under **). Instead 

 of being acuminate, the lower valve is rounded and crenulate at the 

 apex as in Orophus. The prominent veins, pointed tegmina, and 

 the row of raised tubercles on their costal margin, however, are 

 identical with those of the male. The female specimen is not in 

 color and probably has faded from immersion in spirits. 



Family MECOPODID.F:. 



Only three genera of the present family of the Tettigonoidea have 

 been recorded from South American territory. None appear to be 

 among the material now being reported upon. Their representatives 

 are all entirely apterous, and can be separated as follows: 



Synopsis of S. A. Genera of Mecopodid^. 

 A. Legs very long and slender, the hind femora more than twice the length of 



the body, at base but little enlarged Rhamniatopoda Redtenbacher. 



A A. Legs less elongate, the hind femora less than twice the length of the body, at 

 the base rather robust. 

 b. Meso- and metasternum two-spined on each side of middle. 



Tabaria Walker. 

 bb. Meso- and metasternum one-spined on each side of middle. 



Encenlra Redtenbacher.
