286 European Butterflies and Moths. 



GENUS IV.— SOPHRONIA (GUfiN.). 



All the wings coloured alike, and the border interrupted in the middle. The larvcTC 

 have fourteen legs and raised spots, and undergo their transformations in a soft cocoon. 

 The wings of the moth are flat in repose. The only species, *S. Emortiialis (W. V.), has 

 greyish wings^ the fore-wings with two straight white transverse lines, the outermost con- 

 tinued on the hind-wings ; and a white central lunule. Expands from i to i^ inches. 

 Inhabits Central Europe in May ; rare in England. The larva is brownish-yellow, with a 

 dark line on the back, and blackish spots on the upper part of the sides. It feeds on oak in 

 September. 



GENUS V. — SIMl'LICIA (GUfiN.). 



Allied to Zanclognatha, but the fore-wings are narrower, and the hind-wings paler. The 

 only s-pecies, 6'. Rcctalis (Eversm.), has fawn-coloured fore -wings, with two indistinct dark 

 transverse lines, a dark central lunule, and a straight sharply-defined pale yellow subter- 

 minal line. Expands from i^ to li inches. Inhabits South-Central Europe, and Northern and 

 Western Asia in July. 



GENUS VI. — NODARIA (GUliN.). 



Differs from SimpHcia and Zanclognatha in its much more obtuse fore-wings ; from the 

 former in the presence of an accessory cell on the fore-wings ; and from the latter in nervules 

 4 and 5 of the hind-wings rising close together. The only species, M. Nodosalis (Herr.- 

 Schaff.), is very variable ; it is reddish, yellowish, or iron-grey, with three more or less distinct 

 darker lines, the inner line arched and denticulated, and the elbowed line irregular, the latter 

 marked with yellowish-white dots, shaded or dotted with black within ; and a black line 

 before the fringes ; the reniform stigma is black, slightly oval, and well marked. The hind- 

 wings are paler, and sometimes yellowish. Expands about i inch. Inhabits Spain and 

 Sicily in June and autumn. 



GENUS VII. — ZANCLOGNATHA (LED.). 



Fore-wings moderately broad, with the tips rectangular and rather prominent, and the 

 hind margin slightly rounded ; yellowish or brownish-grey, with a dark central lunule, two 

 dark transverse lines, the elbowed line curved round the central lunule, and a straight or 

 slightly arched white or somewhat dusky subterminal line ; hind-wings with the hind margin 

 rather convex ; paler, with traces of a dark curved stripe, and the commencement of a light 

 stripe at the anal angle, which diverges from the hind margin in front. The antennae of the 

 male are pubescent or ciliated, and their front coxse and femora are very long and slender; 

 the latter, as well as the very thickly scaled front tibiae, are provided with a long 

 tuft of hair, which can be spread out like a fan, whence the name of " fan-foot," given to 

 some of these moths. The larvae have sixteen legs, and are naked, and slenderer towards each 

 end. They feed from autumn to May, and undergo their transformations in a slight cocoon. 

 The moths appear in June and July, and rest with their wings flat. This genus may be 

 divided into two sections : — 



A. The males ivith no front tarsi, or knot-like thickenings on the antcnncc ; the marginal line 

 of the fore-wings sharply black, and not interrupted.
