 the black spot in the cell is sometimes a double spot; another black

 Types in my collection. 



Genitalia. Harpagines very long and very narrow, especially 

 so considering the sm.all size of the species; the base wider, though 

 narrow, tapering fairly rapidly into the usual long arm-like process 

 terminating in a subspatulate apex, really being more a short heavy 

 slight^ hooked extremity than spatulate ; the bristles are not 

 numerous, they are long and fairly stout ; anellus cone-shaped ; 

 aedoeagus shortish and of moderate width ; cingulum long and narrow ; 

 tegumen a very narrow well-raised ridge at the rear of the cheeks, 

 which are more quadrate, with a waived front margin ; the bristles 

 are very fine and longish, with the falces long and rather narrow ; 

 terminating as usual in a fine slight hook. 



Androconia almost round with nine rows of reticulations placed 

 widely apart, the sculpturing being also widely apart vertically; 

 the sculpturing is rather small.
