Genus Protoculex. 465 



composed of 5 to 7 straight spines serrated finely and irregularly 

 on one side, serrations small. 



Full grown larvae have been found in July in New Jersey 

 and again in August and September. They live mainly in wood- 

 land pools (J. B. Smith), and probably winter in egg condition. 

 There is no record of its capture in towns or houses in New 

 Jersey, its haunts mainly being swamps.
