are situated at two fifths of length from base, thence very 

 gradually widened to apex, width at base about half that at 

 spiracles and one fourth that at apex; length about two and 

 one-half times width at apex ; length of second tergite a little less 

 than twice width at apex and slightly longer than first; third 

 and fourth tergites distinctly broadened apically, with the poste- 

 rolateral angles prominent; fifth tergite subquadrate; third, 

 fourth, and fifth tergites subequal in length and width and shorter 

 and broader than second; fifth a little shorter, smooth and 

 shining, decolored, narrowed somewhat to the incurved apex; 

 sixth tergite retracted, first to fifth tergites longitudinally rugose, 

 the rugae freely anastomosing, becoming obsolete at extreme 

 apex of fifth tergite; a continuous median carina on first three 

 tergites, finer on third; first suture sharply impressed, postero- 

 lateral angles of first segment acutely produced; second and 

 third sutures strongly depressed and crenulate, the latter con- 

 stricted, fourth and fifth sutures slightly constricted, the former 

 crenulated at sides; second tergite with shallow gastrocoeli. 

 Hind tibiae with two stout curved spurs, as long as fourth tarsal 

 joint; hind tibiae and tarsi long and slender, the first tarsal 

 joint as long as three following together. 



Stigma long and narrow, about four times as long as wide at 

 insertion of radius, where the margin is straight and not at all 

 angulate; first abscissa of radius about one fourth length of 

 second; second cubital cell three times as long as wide, slightly 

 broader at base; first transverse cubitus nearly vertical below, 

 on upper third swollen and bent at beginning of swollen portion ; 

 second transverse cubitus nearly vertical and decolored, second 

 abscissa of radius swollen at base ; first abscissa of radius strong- 

 ly bisinuate; recurrent vein joining cubitus at extreme apex of 

 first cubital cell, intervening vein decolored; parallel vein in- 

 serted at lower fourth; submedian cell considerably longer than 

 median ; transverse median vein vertical.
