on the ventro-cephalic margin of the cephalic femora, the form of 

 the stridulating field of the male tegmina and the color distribution 

 at the base of the tegmina are as in Pycnopalpa, while the tegminal 

 venation and the non-erose character of the tegmina are as in To- 

 pana. As the majority of the striking features accord with Pycno- 

 palpa this association is clearly the more justifiable course to pur- 

 sue, although nibiginosa is a definite proof of the common origin of 

 the two genera. 



Topana cincticornis (StS^l). 



1873. P[lagioptera] cincticornis Stal, Ofv. K. Vetensk.-Akad. Forhandl., 

 XXX, p. 4.3. [Brazil.] 



Chapada, State of Matto Grosso. April, July and August. (H. 

 H. Smith; one labelled ''highland".) One male, four females. 

 [U. S. N. M.] 



Bruner''« has recorded the species from this locality. These 

 specimens agree with Stal's description, but are somewhat smaller 

 than the measurements given for the species by Brunner. The 

 species has been definitely recorded from Rio de Janeiro, Nova Fri- 

 burgo, Matto Grosso and Chapada, Brazil, and Luque, Paraguay, 

 as well as general ''Brazil" and "Paraguay" records. 



Diplophyllus ensifolius Saussure. 



1859. Ph[ijlloptera {Diplophyllus)] ensifolia Saussure, Revue et Magasin de 

 Zoologie, 2e ser., XI, p. 202. [Bahia, Brazil.] 



Corumba, State of Matto Grosso. March. (H. H. Smith; 

 highland.) One female. [U. S. N. M.] 



This specimen agrees with the two previous descriptions (Saussure 

 and Brunner), which were based on the male sex, but has the teg- 

 mina shorter (33 mm. instead of 39) and narrower (10 instead of 11) 

 than Brunner's measurements of the same. When compared with a 

 female of D. pundatus (Stal), from Montserrat, West Indies, ensi- 

 folius is seen to be a more slender insect, with less globose eyes, 

 more regularly lanceolate and less angulate tegmina, and much 

 more elongate, narrower and regularly arcuate ovipositor, which 

 has the distal third of its dorsal margin crenulato-serrate and the 

 same portion of the ventral margin recurved serrato-dentate. The 

 length of the ovipositor is 9.6 mm.; the median depth of the same, 

 1.9.
