haricot leaves laid in the beds, nests, etc., soon become covered 

 v?ith the bugs, which may then be burned, and the same process 

 repeated until the last have disappeared. Others advocate thor- 

 ough fumigation with sulphur. Bisulphide of carbon too may be 

 sprayed over the infected places and things, care being taken to 

 exclude all heat, or lights as it forms with the air an explosive 

 mixture. 



Other members of the Bug family are Acanthia Pipistrella, 

 Reduvius Personatus, which lives mainly in woods and has 

 been known to bite man producing large and painful swellings ; 

 the Harpactor Cruentus of Southern France ; the Eulyes 

 Amaena of Borneo and Java ; the Arilus Serratus of Brazil ; the 

 Nepo Cinerea or water scorpion which bites painfully ; and 

 Notonecta Glauca, the bite of which causes con,siderable 

 suffering. It is not recorded that these bite animals but their 

 attacks on man are suggestive.
