]c.n<i' as l)asul }):iir. Foil' tarsus slender. Win^' a little narrower 

 than nsual: discal cell not as wide at apex as at inner cross-vein, 

 the latter noticeably in front of middle of cell; fifth vein continued 

 straight beyond outer cross-vein for about half tiie length of latter, 

 tlien rather abruptly dellected, the section beyond cross-vein dis-

In this and the following four species each humeral angle has two 

 distinct In-istles. except in co/eopfrafa which has the second bristle 

 either minute or absent. Hendel in describing //(ar/nifica did not 

 mention the humej'al bristle, but it veiy probably is pre.sent in du- 

 plicate as in the others. 



STEGANA ATRIFRONS Mallocli. 



Feutole. — Similar U) the last species, but the frons and scutelliun 

 are entirely l)lack. the mid and hind femora are black on apical 

 half and the tibiae of these legs are broadly blackened basally. 



The face has a sharp carina on upper half in center, the inner 

 cross-^ein is at middle of discal cell, the A\ing is broader as is also 

 the discal cell, and the outer cioss-\ein is at its own length from apex 

 of liftli vein, while the latter is deflected closer to the cross-A'ein.
