Thorax. — Dorsum clothed with ferruginous-red pile ; upper portion 

 of mesopleura ferruginous-red, the ferruginous pile reaching down at 

 least half-way from the level of the bases of the wings toward the bases 

 of the legs, the lower portion clothed with black pile; upper end of 

 metapleura clothed with ferruginous-red pile ; sides of median seg- 

 ment with at least an admixture of ferruginous hairs. 



Abdomen. — Dorsum : first five segments clothed with ferruginous- 

 red pile ; epipygium black and with a very distinct longitudinal me- 

 dian carina on its apical portion. Venter dark ; hypopygiura without
