may be said of the grey species of the genus Ephestia which 

 frequent similar situations. Plodia interpunctella, however, 

 when sitting in the same posture on the wall of a grain ware- 

 house, looks like a black oat-grain stuck there, the sudden 

 change of colour in the middle of its wings giving the effect 

 of the reflection of light on the glossy surface of the grain. 

 Outside the corn warehouses little bits of yellow husk or 

 chaff sometimes seem to be sticking about, but on close in- 

 spection reveal themselves as Gelechia cerealella. 



The, apparent, bit of goose-down entangled with a haw- 

 thorn twig, is often Liparis aurijlua, the long loose downy 

 scales in its dorsal margin greatly aiding the deception. 

 Orgyia piidibunda hanging to a leaf, with fluffy legs out- 

 spread, or on the ground under a hedge, may easily be passed 

 over for a large female sallow catkin, bursting with ripe seeds ; 

 while a Cerura vinula, or better still, a pair of the same, 

 sitting on a plant of dwarf sallow {Salix fusca) is even more 

 admirably concealed by its likeness to a spike of catkins with 

 fluffy seeds bursting out all round. 



The resemblance oi Antkocharis cardamines, when at rest, to 

 a leaf of wild chervil has very recently been commented on, 

 but few seem to have observed its still more curious likeness 

 to a bunch of the buds of its usual food plant, Cardamine 

 pratensis. It loves to sit on the flower spike, hanging from 

 the unopened buds, and the peculiar arrangement of its green 

 markings harmonizes most curiously with them, producing 

 a deception which is heightened by the effect of a slight tinge 

 of altered colour produced by the orange patch shining 

 through the green. This resemblance is a case of effect 

 rather than actual likeness, and should be seen to be ap- 

 preciated. Much more easy is it to understand that Colias 

 ediisa and C. Iiyale when at rest with closed wings, on a clover 

 leaf, appear to be faded yellow leaves of the clover, a decep- 

 tion heightened by the rust-like round spot on the middle of 

 the hinder wings beneath. Everyone, too, is familiar with 

 the fact that when Satyriis semele alights suddenly upon a 

 bare place on a heath or hill side, instantly closing its wings 

 and sloping them over sideways, it becomes indistinguishable 

 from the ground on which it rests ; but not everyone is aware 

 that when Vanessa c-albtini floats down upon the ground in a 

 sunny glade and closes its wings, it becomes precisely like a 

 fallen decayed oak leaf, and if the weather becomes cloudy it 

 will lie down on its side, and so complete the deception. 

 Another curious resemblance is that of the beautifully 

 tessellated hind-wings of Argynnis euphrosyne and A. selene
