NIPH ARGUS KOCHIANUS.

few individuals had been observed many years ago. A 

 larva is also found in the well, which is stated by the 

 proprietor to feed on the Niphargi. 



It is named in compliment to the distinguished na- 

 turalist, who first described and figured two of these 

 peculiar and interesting little animals. 



We are inclined to think this species identical with 

 the specimens captured at Bonn, described and figured 

 by Caspary and Hosius, referred to in the synonyms 

 under N. aquilex, but want of specimens from that 

 locality prevent our determining this point. 



The vignette represents a well similar to those in 

 which these animals are frequently found.
