286 BRAZILIAN ORTHOPTERA 



ous in both cases. The type of Scudder's genus Cornops is hivit- 

 tatum, based on a unique female from the eastern slope of the 

 Peruvian Andes. This specimen has been dried from alcohol 

 and in consequence all of the coloration except the striking black 

 pattern is missing, but the structural features are completely 

 preserved. A most casual examination shows that the species 

 does not belong to the genus Cornops as restricted by Giglio- 

 Tos/" but instead it is fully typical of Paracornops there de- 

 scribed by him. In consequence Paracornops falls as a synonym 

 of Cornops. At the present writing I am not acquainted with 

 the insect called Cornops by Giglio-Tos. 



The Para specimens are fully typical of longicorne, which is a 

 close relative of longipenne (DeGeer), described from Surinam. 

 Bruner has erroneously determined as longipenne a species from 

 Sao Paulo, Brazil, ^^ material of both sexes of which, as well as a 

 topotypic (Paramaribo, Surinam; K. Mayo) female of longi- 

 penne, is now before us. We have elsewhere named the species 

 erroneously determined by Bruner, while a comparison of the 

 female of longipenne and the same sex of longicorne show the 

 following important differences: fastigium in longipenne broader 

 than long and transverse, instead of subtrigonal and hardly 

 broader than long as in longicorne, margins of the same thickened 

 and incrassate in longipenne, sharper and more narrow in longi- 

 corne; fastigio-facial angle of longipenne more rounded than in 

 longicorne; facial line not as straight in longipenne as in longi- 

 corne, faintly arcuate; frontal costa distinctly broader in longi- 

 penne, distinctly constricted at the ocellus instead of non-con- 

 stricted as in longicorne, hardly sulcate dorsad of ocellus instead 

 of distinctly so as in longicorne; lateral ocelli larger and more 

 circular in longipenne, smaller and elliptical in longicorne. Teg- 

 mina of longipenne with apex more regularly rounded and less 

 acuminate than in longicorne. Prosternal spine of longipenne 

 blunt, subcylindrical, slightly transverse; of longicorne sharply 

 acuminate, rising from a transverse' pyramidical structure. Dor- 

 sal ovipositor jaws of longipenne with about eleven rather fine 

 marginal teeth and fine discal teeth; of longicorne with four to 

 five large and other small marginal teeth and coarse discal teeth. 

 Cerci of longipenne thick, short, tapering, blunt; of longicorne
