spurs of the rocks, the former being filled mostly with sand, 

 loose stones, and an accumulation of dirt and dead leaves, the 

 latter often filled with large stones that prevented success in 

 the search quite effectually. 



I would find the burrows of the larvae, but could not get a 

 straw into the hole more than a few inches, and never secured 

 a single specimen until I discovered that the larvae only bore 

 from three to four inches and then dig the balance of the hole 

 at right angles; sometimes this angle extends under a flat stone. 



It is very hard to trace the holes after you once break the 

 ground, as they are soon filled up by the debris. 

 . I have only secured one perfect and one badly damaged larva 

 as the result of many years search, not a very good showing, I 

 confess, but at the same time I have had the enjoyment of the 

 quest. 



The perfect specimen was secured under a small flat rock 

 beneath which the tunnel had ended, the entire burrow not 

 being over eight inches long. There is no doubt that the larva 

 is a hentzii, as it is rare to find other species with them. The 

 specimen is about the same as a larva of C. 6-guttata, rather 

 small and darker than the average examples of Cicindela. 



While C. hentzii is not a rare species, it is by no means a 

 common one and is extra local, specimens have been very 

 scarce the past season. 



In the extreme eastern part of Massachusetts a table of the 

 comparative occurence of the species of Cicindela would be about 

 as follows 10 representing the most common. 



C. purpurea 10, C. 6-guttata 10, C. vulgaris 8, C. punctidata 

 8, C. hentzii 3, C. repanda 2, C. marginata i, C. patruela i, 

 C. dorsalis ? 



The first three are found everywhere, the fourth is common 

 in autumn, being often observed on certain streets within the 

 limits of Boston. C. hentzii is, as mentioned above, local and 

 never found except in well defined situations. C. repanda is 

 rather scarce though abundant in sandy fields a few miles in- 

 land. C. marginata is very rare. 



C. patruela, once very common in a sandy field about one 

 mile south of the Newtonville depot, a town a few miles west
