 three fourths length of second; fifth a little shorter; sixth nar- 

 rower than fifth and three fourths its length, narrowed toward 

 the concave-margined apex, smooth and shining; first to fifth 

 tergites thickly, longitudinally rugose, this becoming obsolete 

 on apical half of fifth tergite ; a strong continuous median carina 

 extends to apical fourth of third tergite; a rudimentary median 

 carina near base of fourth tergite ; first suture sharply impressed, 

 its borders on both segments carinately margined, posterolateral 

 angles of first segment acutely produced; second and third 

 sutures somewhat depressed and . distinctly crenulated; fourth 

 suture a little constricted, but not crenulate ; second tergite with

 as long as fourth tarsal joint; hind tibiae and tarsi very long 

 and slender ; first tarsal joint as long as three following together. 



Stigma long and narrow, four times as long as wide at in- 

 sertion of radius where the margin is straight; first abscissa of 

 radius about one fourth length of second; second cubital cell 

 three times as long as high, not at all narrowed toward apex; 

 first transverse cubitus nearly vertical below, on upper third 

 swollen and bent at beginning of swollen portion ; second trans- 

 verse cubitus nearly vertical and decolored; second abscissa of 

 radius swollen at base ; first abscissa of cubitus strongly upcurved 

 and inserted near costa; recurrent vein joining cubitus at ex-
