Head large with frontal margin produced in a rounded lobe, which 

 is turned upward in the specimen; the antero-lateral angles are pro- 

 duced into small processes. The eyes are black and distinct. 



The segments of the thorax are all distinctly separated from each 

 other. The epimera are distinct on the longer side of the body as 

 long, narrow plates on the anterior portion of the lateral margin of 



the first four segments. Ovarian 

 bosses are not present on any of the 

 segments. 



The abdomen is composed of six 

 segments, completely fused in the 

 middle, but indicated on both lat-
