THE PYRALID.E. 



699 



The generic name of Trigonodcs 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 wliere 

 they may live. They 

 are found in India, /''"^ ' ' 



China, Africa, Australia, '^ 



and Jamaica. None of r 

 them reach any great I 

 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 ' , yi^ 



the prevailing hues. 



In the present species 

 the ground colour of the 

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



i 



/' 



(Brown and yellow.) 



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- 

 ralidse we can take but 

 two examples, the first 

 of which is called Carda- 

 myla carinentalis, 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.
