Genus EUCOELA. 

 i. Radial cellule closed. 



A. Wings fringed with longish cilide ; pilose. 

 1. Antennae without an abrupt club. 



Antennae without a club, and as long, longer, or not much shorter 

 than the body, in <$ double the length of the body. Scutellum with a 

 large, elevated, sharply bordered cup, the apex of which projects over 

 the rest of the scutellum, and is clearly margined ; basal fovea3 large, 

 deep, separated by a sharp keel which runs from the cup of scutellum. 

 Second abdominal segment with a hair fringe. Radial cellule closed ; 

 cubitus complete or nearly so. Legs and antennae usually reddish. 

 = Psichacra, Foerster, Verh. z.-b. Ges. Wien, xix, 386. 



Except in having the antennse longer and without a 

 club this group does not differ from the Eucoela sec- 

 tion. The projecting apex of the cup, on which 

 Foerster lays stress, is not of any taxonomic value. 

 The abdominal hair tuft is dense, and the median 

 segment is frequently more or less densely pilose. 

 E. mandibularis, glottiana, and proximo, approach sec- 

 tion 2 in the apical eight joints being thicker than the 

 preceding, but still they do not form a distinct and 

 abrupt club.
