PROTECTIVE COLOURING OF INSECIS. 



Tiieae four pholos show four living insects in iheir natural resting attitudes. The first is ihe Dotted Border moth on a 

 dead oalc-Ieaf, similar in colour, and therefore not easily seen. The second shows the Comma butterfly among dead leaves, 

 with which its brown underside harmonizes. The third is the Hoo!:-tip moth, looUing like a withered leaf, a resemblance helped 

 by the vetn-like lines across its wing. 1 he last photograph shows the Orange-tip butterfly at rest on the flowers of Jack-by-the- 

 ncdge. All are reduced from natural size
