150 THE GROTIAN TORTRIX MOTH, 



which I write this description the wings are 

 pale brown, with an indistinct patch of ochreous 

 yeUow in the middle, and the scallops edged with 

 a band of blackish grey. 



The larva of this insect feeds on the sallow, 

 and is more plentiful in the northern than the 

 southern counties of England. 



We next take the Grotian Tortrix {Dichelia 

 grotiana), the only British member of its genus. 

 It is rather a pretty little insect, the upper pair 

 of wings being ochreous yellow, partially banded 

 with dark brown, and the lower pair, which are 

 rather small in proportion to the insect, being 

 grey-bro\vn, edged with pale ochre. This is 

 rather a southern than a northern insec^-. 



There are perhaps few genera of insects in 

 which the species exhibit more variety than is 

 the case with the genus Peronea. They may, 

 however, be mostly referred to their proper genus 

 by means of their long palpi, their elongated upper 

 wings, and the tufts of raised scales which appeal 

 in the upper pairs. An example of this genus, 

 Peronea variegana, may be seen on Plate XI. fig. 5, 

 and another species, Peronea hastiana, at fig. 10. 



Another species, known to entomologists as the 

 Button Tortrix (Peronea cristana), is so called 

 on account of the button-like prominences on
