third segment, remaining segments exserted and together as 

 long as second segment ; first tergite longer than its apical width, 

 basal width two thirds of apical; second tergite a little shorter 

 than first, a little broadened apically, length subequal to apical 

 width; third tergite nearly three fourths length of second, its 

 length two thirds of apical width; first, second, and third ter- 

 gites completely, coarsely, straight striate and with a complete 

 median carina, strise on second and third tergites slightly diverg- 

 ing caudad; second suture curved, gradually impressed, and 

 subconnate. 



Stigma of medium size, five times as long as wide, radius 

 inserted at two fifths of the length from base; first abscissa of 

 radius three fourths length of second ; second cubital cell nearly 

 twice as long as wide, narrowed apically ; first transverse cubitus 

 oblique, second nearly perpendicular and decolored; recurrent 

 vein entering first cubital cell a distance from apex equal to three 

 fourths length of first abscissa of radius and subequal to second 

 transverse cubitus; parallel vein inserted at lower fifth and 

 curved just before insertion; submedian cell far longer than 

 median; radius in hind wings obsolete; nervellus straight and 

 nearly vertical.

Synopsis of the species. 



a^. Median lobe of mesonotum with an evident, though weak, median carina;

vein. 



6*. Median lobe of mesonotum shagreened and sparsely punctate; third 



abdominal tergite striate only at base and with a very short median 



carina; hind tibial spurs unusually long in the female. 



brownil sp. nov. 

 b'. Median lobe of mesonotum thickly punctate; third tergite striate 

 throughout and without a discernible median carina. 



sanchezi sp. nov. 



a^ Median lobe of mesonotum without median carina and finely, thickly, 



irregularly, roughly wrinkled; third tergite sculptured and carinate 



to three fourths of its length; submedian cell exceeding median by 



much more than the length of the transverse median vein.
