N. sparganii, Esp. The Bur-reed Wain- 

 scot. Fore wings reddish yellow in the male, 

 brownish yellow in the female, dusted with 

 brownish and on the nervures with light 

 grey, with two black dots in place of the 

 anterior transverse line and a complete row 

 of dots on that of the posterior. There is a 

 similar one in front of the fringes between 

 the nervures. The hind wings are yellowish 

 or reddish, grey towards the base. It appears 

 in July and August and is almost as common 

 on the Continent as ^V. arundinis. It has been 

 taken in Surrey. The larva is light or dark 

 greenish, with four darker dorsal lines, obliquely 

 placed black dots between them, and spiracles 

 encircled with brown. The collar and anal 

 plate are bright green and the belly is also 

 green. It lives on the stems of Typha latifoha, 

 SparganiiDii ramosum, etc. 



N. typhae, Esp. The Bulrush Moth. Fore 

 wings with tolerably straight hind margins 

 and obtuse apices, wainscot -brown or red- 

 dish grey, with whitish nervures, bordered 

 more or less with darker, a few dark dots 

 in place of the anterior transverse line and a 

 more complete row in place of the posterior. 

 The reniform stigma is indicated by a light 

 spot. There are small black sagittate spots 

 in place of the submarginal line. The marginal 

 line is composed of black crescents, and the 

 fringes are darker on the basal half, inter- 

 sected with light nervures. In the variety 

 fraterna, Treit. the wings are dark brown 

 and without markings. The hind wings are 

 yellowish with a darker marginal band, inter- 

 sected by the lighter nervures and a blackish, 

 slightly interrupted, curved marginal line. The 

 head and thorax are like the fore wings, and 

 the abdomen is yellowish-grey. It is com- 

 mon throughout Central Europe in August, 

 especially in marshy places, and is the largest 

 species of the Genus. The larva is dirty 

 flesh-colour, with three lighter lines on the back; 

 blackish spiracles, a brownish cervical and a 

 dark brown anal plate. It feeds in the stems 

 of Typha latifolia. The pupa is yellowish 

 brown, elongated, with a blunt raised proboscis 

 sheath, and a wart-like elevation near the anus. 

 It is placed head downwards above the hole 

 in the stem for the emergence of the moth. 



N. geminipuncta, Hatch. The Twin-spotted 



Wainscot. Fore wings greyish-brown, inclining 

 to coppery red, with the margins somewhat 

 lighter, and the nervures irregularly dusted 

 with lighter or darker. There are sometimes 

 small dark streaks in place of the posterior 

 transverse line, and one or two small white 

 dots bordered with black in place of the reni- 

 form stigma. The hind wings are yellowish 

 grey with light fringes, light inner margins 

 and blackish hind margins. It is widely 

 distributed in Central Europe, appearing in 

 August. Var. guttans, Hiibn. has the wings 

 dark, of a red or reddish brown colour, with 

 a dark spot in place of the reniform stigma, 

 and unspotted hind margins. Var. nigricans, 

 Stand, has almost black wings with very 

 indistinct markings. The larva is dirty white, 

 with a black cervical plate and distinct dark 

 brown warts with scattered hairs. It lives in 

 Arundo phraginites. 



N. neurica, Hiibn. Fore wings straw- 

 coloured or brownish-red, lightest on the broad 

 hind margin, with a dark longitudinal streak 

 through the middle, and between this and the 

 hind margin, black dots, of which the second 

 represents the orbicular stigma and the third 

 indicates the inner border of the anterior half 

 of the white-edged reniform stigma. There 

 is a row of black dots bordered on both sides 

 with white, in place of the posterior transverse 

 spot, and a row of black crescents in front 

 of the unicolorous fringes. It is found in the 

 North of Germany and the Rhine district in 

 August. The larva is whitish with a reddish 

 back. It feeds on reeds. 



N. dissoluta, Treit. The Brown-Veined 

 Wainscot. Fore wings dark brown, with the 

 central spot present on the under side. The 

 var. arundineta, Schmidt, has light grej'ish 

 yellow fore wings. The moth is local in 

 Central Europe, and has been taken in the 

 fens of Cambridgeshire. It appears at the 

 end of July and in August. The larva is 

 greyish, with three lighter dorsal stripes and 

 small black warts. It lives in Typha in June. 



Genus Coenobia, Haw. 



This Genus is very like the last, but differs 

 in the short uniformly ciliated antennas of the 

 males, the slender drooping palpi, the pointed, 

 not quadrangular, horny plate on the front, and
