specimen of Metaleptea minor Giglio-Tos, received through Dr. Borelli 

 (the collector of the types) from the Turin Museum, show that the 

 species really is an Orphula and not closely related to Truxalis {Meta- 

 leptea Bruner), while the specimens determined by Bruner really 

 are Hyalopteryx gracilis, answering the description very well. The 

 species is quite distinct from Hyalopteryx and well worthy of generic 

 separation. 



From the known records this species appears to be distributed over 

 a large area, extending from Caiza in the Bolivian Chaco to the Rio 

 Colorado, and east to the Paraguay river region.
