carefully explored as have been a few localities on each shore, 

 numerous cases of remarkable distribution of species will be 

 discovered, fully as interesting as any which have been already 

 noticed. 



Several interesting questions suggest themselves in regard to 

 the Cicindelidae. Cicindela puritana, Q. wacra and C. cupras- 

 ceyis are no doubt comparatively recent forms of a formerly 

 single species. C jnit-ltana, having apparently become isolated 

 at an early date, is now confined to the Connecticut Valley, and 

 is in several respects intermediate between the other two 

 species, which have a wide distribution in the western and 

 southwestern states. C. macra and C. cuprascens probably 

 occur together in many localities. C. macra is the most abun- 

 dant and widespread form, and seems to have a tendency to 

 separate into races, a tendency not yet noticed in 0. cuprascens, 

 and not to be expected in C. puritana, on account of its limited 

 range. 



In tracing out variations of species, it is of course important 

 to pay attention to all variations which tend to become per- 

 manent, in other words to study the formation of races, which 

 is, of course, the first step in the formation of new species. I 

 cannot close this essay without entering a protest against a ten- 

 dency, which has sprung up recently, of ignoring these varia- 

 tions and of regarding as synonyms the names under which 

 they have been described, when in reality they are varieties, iji 

 many cases quite permanent, which are from separate regions 

 and tend very little to run into each other. jEJ. P. Austin.
