 simple; front coxa' transverse, with distinct trocliantin, the cavities 

 open behind; scutelliun rounded behind; niah\s with tifth ventral 

 segment transverse and sixth segment visible; females with fiftli 

 segment prolonged, sixth invisible. In this and many of the fol- 

 lowing tribes the character of the granulation of the eyes is much 

 used in separating the genera. In tliose A\hicb are "coarsely gi-an- 

 ulate" the lines between the facets are deeply iinj)ressed. In the 

 sectmd groui) the gi'anulations are much finer, the lines feebly im- 

 pressed, the siu'face of the eye a])i)earin£i' almost plane. Repre-

This genus comprises seven rather larse, sulicylindi'ical species, 

 having the eyes coarsely granulated, not hairy and the thorax with 

 two to four larye and shallow depi'essions on the dislc. One of the
