HEMIPTERA 



Practically nothing has been done in the Hemiptera in Durham since Hold's time, and 

 the following list is chiefly his. The very names, Bugs, Plant Lice, and Cuckoo Spit, seem 

 to be enough to frighten young entomologists, although there is but one seriously objectionable 

 bug, while there are hundreds of others of great beauty both in form and colour; and 

 the life histories of the Plant Lice or Aphides, with their deeply interesting instances of 

 parthenogenesis, and their curious alternations of form and domicile, present most alluring 

 objects for investigation.
