 Vellea Walker, Cat. Derm. Salt. B. M., II, p. 359 (1869); Kirby, Syn. Cat. Orth.. 



II, p. 451 (1906). 



Only a single species of this genus has been thus far recognized 

 from South America. The present writer had, at one time, a couple 

 of nymphs bearing the locality label "Central America." Whether 

 or not they belonged to another species I cannot say. These insects 

 are now in the collection of Morgan Hebard, Philadelphia, Penn- 



syKania.

Parableta Brunner, Mon. Phaneropt. pp. 26, 253 (1878); Addit. Mon. 

 Phaneropt., pp. 18, 133 (1891). 



This genus is confined to South America, where the known species 



are all tropical in their distribution. Two species have been described 



heretofore, while a third is now added. They may be separated as 



follows: 



Synopsis of the Species of Parableta. 



A. Posterior femora seven- to nine-spined on the internal margin. Ovipositor 

 with the margins entire, smooth, the apex somewhat obtuse. 

 b. Size larger (c?' tegmina 38 mm., 9 , 41 mm.) [Bolivia]. . .boliviana sp. nov. 

 bb. Size smaller (cf tegmina i^ mm., 9, 33 mm.) [Ecuador].
