areas between the named longitudinal nervures and the subradius 

 yet darker. The other longitudinal nervures and cross veins

I have dedicated the species to my friend, Mr. A. C. Jensen- 

 H a a r u p , Silkeborg , who has done so much in exploring the 

 insect fauna of the western Argentine. 



The species, found at Bompland, is, unfortunately, not in good 

 condition ; it has lost its fore legs and setae , but I have no 

 hesitation in describing it. By the peculiar shape of the ventral 

 lobe of 9"^ segment and by the great numbers of cross veins in 

 the basal part of the costal and subcostal areas it differs from 

 the typical species of the genus. Perhaps a new genus ought to 

 be established for the species, but without knowledge of the male 

 I find it best to postpone it.
