DescHption. — Agreeing in all respects with the description of 

 ochracea except for the male characters. Male^ seventh sternite with 

 a slight emargination posteriorly throughout the middle half of the 

 margin and occupied by a ctenidium of black fimbriae which are 

 shorter in the middle and at the ends, also with a few unusually 

 large setae projecting posteriorly over the ctenidium from the pos- 

 terior surface of the segment; eighth sternite with a rather deep 

 rounded emargination which is narrowly bordered at apex, but with- 

 out trace of the large clusters of golden hair found in ochracea.
