species (Ayrion), rests upon a hedge while discussing its cannibal 

 repast, a captured gnat. Hovering just above is the Dragon-Fly's 

 enemy, and sometimes conqueror, the Scorpion-Fly (Panorpa), so called 

 from the appendage to its tail. To its left appears the graceful Lacewing 

 (Hemerobius), green and golden-eyed; the rose-leaf to the right, below, 

 being occupied by a grub, or larva (magnified), of the same carnivorous 

 insect busy in its usual occupation of destroying Aphides . . . .272

A trembling "White" of the garden about to fall into the embrace (to 

 Butterflies always fatal) of a great Green Dragon-Fly 283 



33. RESEMBLANCE AND RELATION. 



The mimicry of vegetable by animal forms is here illustrated by figures of 

 some looping caterpillars, termed " Walking branches," and by that of 

 a moth, the Oak Lappet (Gastropacha quercifolia}, likened to a Walking 

 Leaf. Above the latter, fixed motionless to a branch of hawthorn, 

 which it closely simulates, is the caterpillar of the Brimstone Moth 

 (Rnmia cratagata)}, the moth itself appearing in flight above. On the 

 left, another stick caterpillar that of the Swallow-tail Moth (Ourap- 

 terix sambiicaria), is attached to a branch of elder, of which it affords 

 a close copy in form, colour, and markings. A second specimen of the 

 same in its walking position forms an arch upon the branch below . . 284

34. MOTHS AS IDLERS. 



The Moths in this group are of those not figured in the frontispiece. That 

 in the foreground, beneath the white convolvulus, is the common 

 " Tiger " (Arctia caja) ; the smaller insect above, is the Humming- 

 Bird Sphynx (Macroglossa stellatamm), uncoiling its tongue for 

 insertion into the flower. The large one to the left, the Lime-Hawk 

 (Smerinthus Tilicc). Above, in upward flight, is the elegant " White
