Only from Pittsfield, 111., do we have a good series of females 

 associated with males. In this series there appear to be two types: 

 one is indistinguishable from communis, and the other has large 

 bursa spines; the spermathecal duct branches farther from the bursa, 

 and the bm'sa surface is coarsely reticulate. It is possible that the 

 second type represents the female of indistinctus, but, since the evi- 

 dence is not unequivocal, we have not definitely identified any of the 

 females nor included them in the type series. 



This species will be found in some collections identified by Lane as 

 "species 20."
