 ventral abdominal segment, much more elongate

 times the prothoracic length, regularly but not 

 very greatly narrowing caudad, interocular region

 very low and weak median tubercles separated 

 by a shallow depression of the margin; eyes sub- 

 globose, hardly prominent; antennas imperfect, 

 fifteen joints present. Prothorax with the lat- 

 eral margins subparallel caudad, slightly arcuate 

 constricted cephalad; cephalic margin decidedly
