ThOLOMIGES RlVULA A^) CTEOLJD^. 2Q\ 



*2. H. Cosfastrigalis (Stepli.). — Fore-wings ochreous-biown, paler on the inner margin 

 and in the marginal area, with two dark transverse lines, the inner line zigzag, and the 

 elbowed line very oblique and curved, and only bordered v/ith light below the costa; 

 beyond it is a light dash at the tip, running towards the middle of the inner margin, 

 where it becomes indistinct, and there is a longitudinal dash, dusted with black, in the place 

 of the reniform stigma ; hind-wings whitish. Inhabits Central Europe, but scarce in many 

 places. {H. Kahlibcrgi, Stand., which inhabits Sicily and Macedonia in Jmie, has dark grey 

 fore-wings, with a very indistinct light inner line, and a rather more distinct line just 

 beyond the discoidal cell, where it is arched outwards, and there is a whitish lunule at the 

 end of the cell ; both lines are bordered inside by a black line, and there is a very indis- 

 tinct light subterminal line just before the hind margin ; there are four light dots close to 

 the costa beyond the second line, and others at the base of the fringes ; hind-wings and 

 under side greyish-black.) 



GENUS XIV. — THOLOMIGES (i.ED.). 



Fore-wings with the tips rectangular, with transverse lines and a central lunale ; hind-wings 

 triangular, and slightl}' contracted just below the tips ; the antennae of the male dentated. 

 The only species, * T. Titrfosalis (Wocke), has reddish-grey fore-wings, with the inner line 

 indistinct, and the elbowed line dark brown, bordered with light, very oblique, and very 

 indistinct in the middle, but running to the middle of the inner margin ; the subterminal 

 line is lighter, and shaded with dusky in front, and there is a black central spot. Expands 

 about half an inch. It is found in marshy places in June and July throughout the north of 

 Central Europe, but is very local. 



GENUS XV. — RIVULA (CUE.X.). 



Fore-wings broad, with transverse lines, and the reniform stigma ; hind-wings rather short, 

 and without markings ; antennae of the male slightly ciliated. The larva has sixteen legs, 

 and is clothed with fine short hair. The moth rests with sloping wings. The only species, 

 *R. Scrkcalis (Scop.), has ochre-yellow fore-wings, brownish on the hind margin, with two 

 indistinct double dentated dark transverse lines, and white marginal dots ; the reniform stigma 

 is violet-grey, and marked with two black dots, and the hind-wings are dusted with brown. 

 Expands nearly i inch. Common in Europe and Northern and Western Asia from June 

 to September. The larva is green, with two whitish stripes on the back. It feeds on 

 grass in May and June. 



NYCTEOLID/E. 



Small and slender-bodied moth.s, the thorax rounded in front, and clothed with flattened 

 hair; neither the thorax nor the abdomen crested; legs slender, with smooth scales; fore- 

 wings brownish-grey or whitish, \\ ith more or less distinct transverse and subterminal lines ; 

 hind-wings without markings, and not quite extending to the tip of the abdomen. The 

 larvae have fourteen or si.xteen legs, and are clothed with fine hair ; thej' undergo their trans- 

 formations in a firm boat-shaped cocoon. The moths fly at night. The position of the few 

 genera placed in this group is quite uncertain ; many authors regard them as Bombyces, 

 placing Nola and Paidia among the Lil/iosiiiite, to which the\- arc closely related ; while
