Dytiscidae. The Diving Beetles 



These predaceous ones live in pools and the most sure way 

 to take large one- is to suspend a minnow trap baited with a 

 piece of fish. The opening of the trap should not be too large, 

 and part of the trap should be above water so that the beetles 

 will have air and not die, swell and so he unfit for mounting. 

 Scraping the edges of pools will get the others. One should 

 wade in with a long-handled net and reach across the pool 

 under water and scrape slowly upward, keeping quiet and not 

 casting a shadow. Results will repay the care taken. 



I, \' cophilus Leach 



L. maculosus (Germ.) (2351). This "pool loving" species 

 as its name indicates, is commonly found in the smaller 

 pools on the Island. It is the first of the family to appeal 1 in 

 the spring, and remains until cold weather, when it probably 

 hibernates.
