character in this genus. The insect, piceus, from Algiers, N. 

 Africa, is blackish with yellow spots; cross-vein r absent; cell 1st 

 M2 open, the outer deflection of M 3 being obliterated; Rs rather 

 straight, but diverging strongly from Ri, etc. Gymnastes Brunetti; 

 not distinct from Teucholabis, the opinion of Mr. F. W. Edwards 

 who is well acquainted with the Old World Fauna. 



Teucholabis Osten Sacken 



The number of species belonging to this genus now known from 

 the American Continent is 21, of which I have seen 12. 



Teucholabis venezuelensis Macq. 1 and T. melanocephala Fabr. 2 

 have not hitherto been recognized as belonging to this genus but 

 there can be no question as to their position. Both species are 

 described as having pale clouds on the wings, not distinct brown 

 bands as in the polita group. 



The Limnobia bifasciata Fabr. 3 is likewise a Teucholabis and con- 

 specific with trifasciata End; 4 however the Fabrician name is 

 preoccupied 5 and so Enderlein's name is valid. 



Rhamphidia scapularis Macq. 6 is a Teucholabis as was indicated 

 by Osten Sacken in 1869; still Kertesz (1902) retains it under 

 Rhamphidia; the same statement applies to Limnobia simplex 

 Wied 7 which is retained in Limnobia.
