156 European Butterflies axd Moths. 



dark longitudinal streak in the middle, suffused on the side towards the inner margin, a small 

 black spot in the place of the rcniform stigma more or less surrounded with white, and black 

 marginal dots ; hind-wings whitish, with the hind margin grey. All the wings with a dark 

 central lunule beneath. Expands from i to i] inches. Local in Central Europe, occurring in 

 July and August. The larva is dirty white, with the back pale reddish, and eight small brown 

 raised spots on the 4th and Sth segments, and four black ones on each of the following segments. 

 The head and plates are brownish. It feeds in Typha till June, and the pupa is placed with the 

 head downwards. 



7. N. Nairica (Hiibn.). — Very near the last species, but the central spots of the under side are 

 wanting, and the hind-wings are unicolorous brownish-grey. It inhabits Germany in July and 

 August, and probably other countries, but has been confounded with the last species. The larva 

 is bluish-grey, with three pale yellow stripes on the back, and four small black raised spots on 

 each segment ; the head is dark brown. It lives in Typha till June. 



*S. N. Breviliiiea (Fenn). — Fore-wings brownish-ochreous, with scattered black scales, a short 

 black dash from the middle of the base, a curved transverse row of black dots, but no marginal 

 dots ; hind-wings grey, paler at the base, with the transverse row of dots very indistinctly marked. 

 Expands \\ inches. It has been taken, flying among Typha latifolia at dusk, at Ranworth, 

 in Norfolk. 



g. N. Stiguiatica (Eversm.). — Straw-colour, more or less shaded with black or brown, a 

 brown streak on the medium nervure, a whitish dot in the middle, and the nervures blackish 

 towards the hind margin ; hind-wings pale grey. Inhabits South Russia and Siberia. 



GENUS V. — CCENOBIA (STEPH.). 



Small ; fore-wings with the tip somewhat rounded and truncated behind ; rounded above 

 the anal angle, and narrower in the female ; almost without markings. The antennae are not 

 dentated, but finely ciliated ; the palpi are slender, with the last joint very short, and the 

 tongue is long and slender ; the abdomen is very long. The only species, * C. Riifa (Haw.), 

 Despccta (Tr.), is reddish-ochreous, with the nervures finely dusted with grey and white, and 

 a row of black dots beyond the middle ; hind-wings white, thinly dusted with grey. Expands 

 rather less than i inch. It is found in marshy places in June and July throughout the 

 northern half of Central Europe. The larva lives in the stems of Jnnciis lamprocarpus , where 

 it becomes a pupa in June. 



GENUS VI. — SENTA (STEPH.). 



Fore-wings nearly three times as long as broad; the costa and inner margin nearly 

 parallel, with the tip sharply rectangular and truncated in front ; the hinder angle slightly 

 concave ; only the orbicular and reniform stigmata are marked. Hind-wings broad, slightly 

 contracted below the tip. The tongue is horny, and the antennae are not dentated. The 

 only species, * S. Maritima (Tausch.), Uivce (Hlibn.), has the fore-wings ochreous, with the 

 costa and inner margin pale grey ; sometimes the wings are wholly brownish-grey, with white 

 veins, and a row of black dots beyond the middle ; the two stigmata are round and of equal 

 size, and are generally finely surrounded with white, but are often indistinct ; the hind-wings 

 are white. It is very variable ; sometimes the spaces between the pale veins are filled up 

 with black as far as the row of dots (as in Uhur, figured by Herrich-SchtiiTer, Noctuce, Fig. 397); 

 in variety Bipnnctata (Haw.) the veins are scarcely paler, and the stigmata are deep black
