LEAF-LIKE MOTHS. 693 



of India and Java, in whicli the upper wings are beautifully 

 glossed with shining green. The other is Opiiideres sviaragdi- 

 jnda, in which the wings are purple-brown, on which is laid a 

 pattern defined as sharply as if painted with emerald -green. 

 The specific name is Greek, and signifies " emerald painted." 



On Plate XVI. Fig. 2 is seen a Moth called Fhj/llodcs con- 

 sohrina, a native of Silhet. 



The generic name is formed from a Greek word signifying " a 

 leaf," and is given to the insect on account of the singularly leaf- 

 life appearance of the upper wings. They are dark brown in 

 colour, and have a line along the centre which looks just like 

 the central rib of a leaf. Towards the tip the brown takes a 

 purple gloss, and there is a doubly curved mark of chocolate 

 in the middle. 



The lower wings are dark brown, changing to rich purple, just 

 like that of our Purple Emperor. Towards the anal angle of 

 the wing there is a large spot of bright scarlet, with a white 

 centre. The body is brown, glossed with purple. The reader 

 will see that the distribution of the colours is intended for the 

 protection of the insect. The brilliant scarlet, white, and purple 

 of the lower wings would make it exceedingly conspicuous, 

 but when their glories are veiled under the leaf-like upper wings, 

 the insect becomes scarcely distinguishable from dead foliage. 



The insect which is shown on page 094 is found in India, 

 China, Borneo, the Philippines, and Java. 



It is one of the most variable insects, scarcely any two 

 specimens being alike. That which is the subject of the illustra- 

 tion is coloured as follows. The upper wings are dun brown 

 from the base to half their length, and then change to yellowish 

 brown speckled with black. The spots are black, edged with 

 white. A similar division of colour occurs in the lower wings, 

 except that the basal portion is chocolate. In the middle tliere 

 is a large oval mark of pale blue. The specimen which has been 

 described was taken in Silhet. 



Another inhabitant of Silhet now comes before us called 

 Nyctipao albicincta, both names being very appropriate. 



The ground colour of both pairs of wings is dark brown,
