 dark at the knees and along the distal one-third, the basal two- 

 thirds light-colored. Third antennal segment with a single sen- 

 sorium near the distal end, fourth segment with none, fifth

Apterous viviparous female : Antennae with third segment, base 

 of fourth, and fifth, light-colored, other parts dusky. Femora on 

 all legs dusky, knees black. Tibiae yellowish near the base but 

 black at distal end. Yellowish areas on front tibiae cover about 

 one-half of segment, on middle and rear legs cover about three- 

 fourths of the segment. Third antennal segment approximately 

 equal in length to the fourth and fifth together. Fourth segment 

 much shorter than the fifth but slightly longer than the sixth. 

 Third and fourth segments without sensoria; fifth with a small 

 sensorium near the center and a larger one at the distal end.

Cauda broadly rounded. Body covered with small irregular 

 black spots ; a single hair arises from each one of these. Cornicles 

 volcano-shaped. Body, legs and antennae with long spine-like 

 hairs. 



Alate viviparous female : Antennae with third segment at the
