EPHYDRIDAE OF THE UNIVERSITY COLLECTION. 



Besides the species described above as new, I find the folloM^- 

 ing in the collection of the University of California, not here- 

 tofore known to occur in this region: 



Notiphila virgata Coquillett. The general color is much

 type in many cases, .specimens varying somewhat. Some have 

 a whitish dot above the antennae, and in others the mark- 

 ings of the legs vary slightly. A few specimens, which I regard
