THYATIRA. 3 



with two of the sub-costal nervules forking near the tip ; hind- 

 wings with the discoidal nervule rising near the upper median 

 nervule. Larva with deep incisions, and bifid elevations on 

 the back. 



The type of this genus is widely distributed in Europe and 

 Northern and Western Asia. Species or varieties differing little 

 from the European form are likewise met with in India, and 

 in North America as far south as Mexico.

The Peach-blossom Moth, which is named from the colour 

 of the spots on the fore-wings, is one of the prettiest species 

 found in Britain, and is not rare. The fore-wings are olive-brown, 

 with dark waved transverse lines, darkest towards the base, and 

 with five pale rose-coloured spots on each wing. The largest 

 of these is at the base, and is clouded with brown ; two are 

 near the tip, and are sometimes united ; a fourth is situated at 

 the hinder angle, and has a brown spot in the middle, and the 

 smallest is on the inner margin. The hind-wings are ochreous- 

 grey, with a pale waved line near the middle, and are darker 

 in the females than in the males.
