(Brown and yellow.) 



The generic name of Trigonodes is Greek, signifying a triangle, 

 and is well applied to all the members of the genus. The 

 triangle is the chief character of the insects, no matter where 

 they may live. They 

 are found in India, 

 China, Africa, Australia, 

 and Jamaica. None of 

 them reach any great 

 size, the present species 

 being, as may be in- 

 ferred from its name, 

 the largest of the genus. 

 There is but little di- 

 versity in colour among 

 them, brown, chocolate, 

 yellow, and grey being 

 the prevailing hues. 



In the present species 

 the ground colour of the 



upper wing is pale yellowish brown, on which are placed three 

 bold marks of dark chocolate-brown. The lower wings are 



yellow-grey, and the 

 two pointed stripes upon 

 them are rather dark 

 brown. This species 

 comes from Hindostan. 



Of the great and im- 

 portant group of the Py- 

 ralidae we can take but 

 two examples, the first 

 of which is called Carda- 

 myla carincntalis, and is 

 a native of Australia. 



It is one of the many 

 insects which require a 

 favourable light before 

 their beauties are appreciated. At first it looks as if it were 

 simply coloured with black and orange, but with a good light 

 it is seen to be really a splendid example of colouring.
