THE TWIN-SPOTTED. 297 



The moth flies among reeds, etc., in August and September. 

 Its chief localities in England are in East and South-east Kent, 

 in which county the first British specimens were obtained by 

 Mr. Sydney Webb in 1879. In 1899 a specimen reared from a 

 caterpillar found in a stem of Typha^ was recorded from Suffolk 

 (Woodbridge district) ; and in 1901 the species was recorded 

 from South Devon. It is also not uncommon "between Old 

 Head of Kinsale and Glandore," Co. Cork, Ireland. 



The Bulrush Wainscot {Nonagria typhce.') 



The fore wings of this species (Plate 144, Fig. 5), usually of a 

 pale whity-brown colour, in some specimens are reddish tinged; 

 or they may be almost uniformly reddish brown or blackish 

 (var. fraterna, Treit.). The row of black spots on the outer area 

 are wedge-shaped and are placed just before the margin. The 

 caterpillar is pale ochreous more or less tinged with pink; a 

 paler line along the spiracles ; head and plate on first ring of 

 the body red-brown. July to August, in stems of TypJia. The 

 moth flies in August and September, and although it may be 

 netted when on the wing at dusk, or at light, it is obtained in 

 better condition by rearing it from the chrysalis, which may be 

 found in the stems (Plate 148, Fig. 3), those of the previous 

 year for choice, of reed mace. Generally distributed in England 

 up to Yorkshire ; it has been recorded also from Northumber- 

 land and the Scottish border. It is common in southern 

 Ireland, and found northwards up to Sligo, Tyrone, and 

 Armagh. 



The Twin-spotted {Nonagria gcmimpuncta). 



This species, shown on Plate 144, Figs. 6, 7, varies in colour 

 from pale brown, more or less suftused with grey, through 

 darker, or reddish brown to blackish (var. nigricans^ Staud.).
