M}' idea, as a result of several 5^ ears' observation, is that 

 those individuals which live on white sand are marked with 

 wide white bands, while those which live on mud-deltas are 

 heavily h\3.Qk, for purposes of protection. 



This means a variation of locality, and so I take the liberty 

 of naming this variety, which Mr. Leng has so ably described 

 on page 152 of his revision as 



C. nigrita nov. var of C. hirticollis. 



Let me add to his description. C. 7iigrita is smaller than 

 hirticollis, — length of former .42 inch, while average Rhode 

 Island hirticollis == .55 inch; more active. Very local, in- 

 habits muddy shores, occurs in spots along Atlantic coast 

 from Rhode Island to New Jersey. Described from scores of 

 specimens from mud-flats of Warwick, R. I. 



G. pnnctnlata Fab. 



Common July 12th to September loth. This little fellow is 

 very social and cosmopolitan. Occurs in gardens, front yards 

 and even on the main streets of Providence. It varies a little 

 in size, but Rhode Island specimens are quite regular in 

 markings. 



This is the only Cicindela I have ever taken at light. 



C. dorsalis Say. 



Common July 4th to 15th, perhaps later. This beautiful 

 white Cicindela occurs at the sea-shore resorts where extensive 

 stretches of sand occur, as at Watch Hill, Block Island and 

 Newport. 



I have discovered that, as the season advances, the elytral 

 markings disappear by the wearing action of the sand in which 

 they live. 



Late in the season we get heavily immaculate specimens, 

 but they rarely have a pink appearance. 



Care must be taken in drying specimens, as the elytra dis- 

 color so readily. I find that if the elytra are lifted, and a 

 piece of paper be introduced, and removed when the body is 

 dried, many good specimens are saved. 



C. Hentzii Dej. 



The only rufous-abdomen variety we have. Rare. Taken 

 in July only, by Kertz and Professor Calder.
