Dr. St&l reports this species to have been taken in Sitka. Specimens 

 belonging to the Museum of Comparative Zoology, kindly sent to me 

 for study by Dr. H. A von Hagen, were taken at San Diego and Bard's 

 Eanch, Cal. These specimens are larger than those from the Eocky 

 Mountain region, of which many have passed through my hands, from 

 various localities in Utah, New Mexico, etc. In the western suburbs 

 of Denver, Colo., it may be met with in untold numbers on the dark, 

 damp, sandy, and muddy soil, during the month of August. A few 

 specimens occurred to me on dark, damp soil, next the stream of water 

 running down the Beaver Brook Gulch, and also in similar spots 

 in Clear Creek Canon. I can find no characters to separate it from 

 specimens which I collected in Hayti.on the marshy banks of the Grand 

 Anse Eiver in May, nor from Cuban specimens received from Professor 

 Poey. It occurs also in New Jersey and on the dark mud of the sea- 

 coast of Maryland. 



Dr. Packard collected it near Georgetown, Colo., July 8, at an eleva- 

 tion of 9,500 feet, and also near Salt Lake, LTtah, July 27.
