376 THE CANADIAN ENTOMOLOGIST 



was at one time connected with the British Museum and died in 

 1836, and Stephens, James Francis (1792-1852), an English ento- 

 mologist, were all advocates of the eclectic system and originators 

 of classifications along such lines. 



MacLeay, William Sharp, an English entomologist, who 

 published between 1819 and 1838, was the author of what was 

 known as the quinary system, in which insects were arranged in 

 circular groups of fives, so placed as to bring those having the 

 nearest resemblance, contiguous to one another in their several 

 circles. By some authors, insects were also arranged according 

 to the condition of their food, such as those feeding on living 

 substances (Thalerophaga) and those feeding on dead substances 

 (Saprophaga) . These groups were subdivided, but such systems 

 on the whole were never brought to any degree of perfection.
