INSECT INTRUDERS. 



As regards colouring the forms which 

 live on trees or amongst rocks are of that 

 peculiar smoky brown or grey which is 

 par excellence the most difficult to ' spot' 

 when the insect is quiescent almost 

 impossible in fact save to a highly trained 

 and observant eye. And yet some of the 

 smaller tree forms are often met with 

 in camp especially at al fresco lunches 

 in the jungle where one may often see 

 an intruder or two (such as the small 

 one shown enlarged) on the snowy table 

 cloth, his protective colouring here mak- 

 ing him all the more visible. 



Again, the foliage dwelling forms have 

 acquired that peculiar vivid tint of green 

 with perhaps yellowish and brown mark- 

 ings which enables them to lie perdu on 

 leaf or green twig till some unwary insect 

 approaches within their reach ; finally, 

 there are other vivid and beautifully 

 coloured banded or spotted species which 

 are usually found amongst flowers, such 

 as the one here shown on the Canna
