 possibly the H. hiterrupta Bruiiner from Sao Paulo, Brazil, is also 

 characterized in the subjoined sjnioptic table, as also species described 

 by each, Malcolm Burr and Giglio-Tos.

HYALOPTERYX RUFIPENNIS Charpentier. 



Hyalopfery.r rufipemiis Charpentier, Orthopt. Descr. et Depict., 1853, pi. xlvi. 

 Charpentier simply gives Brazil as the habitat of his species. It 

 may also occur in Paraguay. 



HYALOPTERYX INTERRUPTA Brunner? or HYALOPTERYX LAMEL- 



LIPES, new species. 



There are before me as I Avrite several specimens of a species of this 

 genus that possess the characters given at cc in the synoptic table. 

 They come from Sao Paulo, Brazil, which is in the same general region 

 as Paraguay. 



Bang Haase lists Hyalopteryx interrupta Brunner in one of his cata- 

 logues. I have been unable to discover the place of publication of this 

 species, hence do not know whether it is the same as lamellvpes. It also 

 belongs to the same general region. 



HYALOPTERYX SPECULARIS, new species. 



Pale flavo-testaceous to bruneo-testaceous, the tegmina more or less 

 strongl}^ and regularly conspersed with fuscous. The hind wings,
