INTRODUCTION. 



A LL who have travelled east of Suez 

 ** have been brought into sharp, one 

 may say into unpleasant, contact 

 with one great class of Animal Life 

 the World of Insects. The person 

 possessed of no naturalist proclivities 

 may pass his or her life in England with 

 but the slenderest acquaintance with that 

 great mass of life popularly designated 

 'bugs.' Their knowledge is probably 

 limited to the household fly arid blue- 

 bottle, the sugar loving wasp and those 

 ' nasty ' spiders, which by the way are 

 not insects.
