THE ZOEGiAN TOKTKIX. 513 



An allied species, Ephippiphora fcenella, is shown at Fig-. 1. 

 It is a very pretty little creatui'e, the upper wings being dark 

 brow^n, each having a pretty white spot, as seen in the illustra- 

 tion. The under wings are nearly as dark as the upper pair. 



While we are engaged on this subject of Tortrices that are 

 destructive to fruit, we must mention the W^berian Tortkix 

 {Semasla Wceherana), which atfects the various stoue-fruiL just 

 as the Caddis Moth attacks the apples. 



I scarcely know a more lovely Moth than this little being, its 

 beauties, however, being so minute that they can scarcely be even 

 suspected until the magnifying glass is brought to bear upon 

 them. When viewed with a moderately powerful lens and a 

 good light, the upper wings start into sudden and unexpected 

 beauty. Their rich, satiny warm brown surface is seen to be 

 covered with innumerable tiny and delicate pencillings, scarcely 

 wider than a hair, but each traced with perfect decision, and 

 glittering as if it were formed of highly burnished gold. 



Although belonging to the Tortrices, it is not a leaf-roller, 

 nor even a fruit-eater, but restricts itself to the inner bark, on 

 which it seems to feed exclusively. Although thus hidden 

 from human sight, it can easily be detected, because, like tlie 

 Codlin Moth, it ejects from the mouth of the burrow the 

 digested remains of its food, which may be seen in the form of 

 fine yellow powder. Brushing oil into the holes has been 

 strongly recommended as a mode of killing these mischievous 

 caterpillars. I should think that to force a drop of oil sharply 

 into the burrow by means of a fine syringe would be much 

 more effectual. Oil is instantaneously fatal to insects, because 

 it chokes up the spiracles and prevents them from breathing. 

 But, it must first reach the spiracles, and I rather doubt 

 whether the mere brushing oil over the mouths of the burrows 

 would have that effect, whereas, forcing it into the tunnels 

 with a smart push of the syringe-piston could scarcely fail 

 of that effect. 



The last of the Tortrices which we can mention in this work 

 is the ZoEGiAN ToRTuix {Tortrix zoegana). 



The colouring of this insect is very bold. The ground colour 

 of the upper wings is yellow, and the upper part of their
