This insect and the stick-caterpillar may be seen in the insect exhibits on the basement at South Kensington, having been figured from them by the kind permission of Professor Fig. 19.—A locust (Cycloptera speculaia) which closely resembles a leaf. (From an exhibit in the British Natural History Museum.) Perhaps one of the most striking instances of special protective resemblance is that of the Malayan leaf-butterfly (Kallima paralecta).
