but does not quite bear out Wilde's statement that it is " of a bluish 

 grey colour." The larva feeds in the same way as that of arundineta, 

 entering the reed stem about half way up just above a node, and 

 feeding on the inner lining of the reed. When full-fed it leaves the 

 stem and enters an old stem low down, it makes its emergence hole at 

 the base of the reed, and then walks up the stem as far as the node, 

 makes its puparium, and pupates head downwards. 



The pupa is 16 mm. long and very slender, of a bright yellowish 

 brown colour and with a distinct beak. The kremaster is furnished 

 with many small hooks and bristles. The spiracles are very prominent. 

 As regards the imago, the Continental specimens are paler than ours, 

 especially the Vienna ones, which are of a yellowish olive colour. In 

 addition to the type, we have bred two forms not previously known 

 on the Continent : (1) a blackish-brown form, for which I suggest 

 the name "fusca," and (2), a reddish form, which I call " riifesceiis." 

 The insect is extremely local, only occurring in one very small spot 

 at present.
