Type locality. — Grassy plots about Peking. Some two- 

 to three hundred specimens were taken on September 22nd 

 by sweeping the high, rank growth of grass under the pine 

 trees of one of the burial grounds south of Ch'ao Yang An. 

 One specimen was also found in moss scraped off the pave- 

 ment in the burial ground, and another was found in company 

 with the species mentioned above. 



The individuals of this species are rapid walkers (com- 

 pared with other species of this genus) and have a very strong 

 tendency to rise or climb. 



Types. — In my collection, No. 21152-2. Specimens 

 also sent to Dr. A. C. Oudemans and Dr. Max Sellnick.
