GENISTIS, Htsner. (LITHOSIA, Szcr. ++ Borspuvat.) 
I have adopted Hiibner’s name for the large footman-moth, having observed a character in that insect not 
hitherto noticed, which, in the present state of our knowledge of the classification of the night-flying Lepidoptera, 
it seems advisable to indicate more decidedly than by a note at the end of the specific description,—namely, the 
existence of three distinct branches radiating from the extremity of the great median vein, and the basal branch 
of the same vein pushed almost to the base of the wing. In the typical Lithosiz (LL. complana) there are only 
two branches at the extremity of the median vein. Moreover, Boisduval has separated it from the other 
Lithosiz, ranking it as distinct as L. rubricollis.

and 105. 
This is the largest species in the genus, measuring from 13 to 2 inches in expanse. The male has the fore 
wings greyish yellow, with the apex broadly dusky, and the base more orange, the costa at the base being blue- 
black ; the remainder of the insect is ochreous yellow. The female is entirely of the latter colour, except that 
each of the fore wings is marked with two large blue-black spots, which, however, are occasionally obsolete. 
The caterpillar is grey-black, with two yellowish dorsal lines spotted with red, separated by a dark line 
spotted in each segment with black ; it feeds on various trees, such as the oak, birch, horse-chesnut, fir, &c., in 
June; and the moth appears in July, and is a widely distributed and abundant species. 

GNOPHRIA, Sreenens. (ATOLMIS, Hitsner.) 
The insect, upon which this group has been proposed, agrees with the typical Lithosie in the elongation 
of its wings and short body, but differs in having three-jointed palpi, conical to the tip; dark colours and 
veining of its fore wing, the median vein emitting three branches, the third being furcate. 

SPECIES 1.—GNOPHRIA RUBRICOLLIS. Puare XX., Fie. 20, 21. 
Synonymes.—Phail. (Noet.) rubricol/is, Linn, ; Donovan, 10, pl. 350, fig. 3; Harris, Aurelian, pl. 43, fig. p.

This species varies from 1 to 14 inch in expanse of the fore wings. It is of a uniform black colour, with 
a red neck, and the tip of the abdomen orange. The caterpillar is ashy-green, with long hairs, and with two 
yellow dorsal lines, and red and black spots on the sides. It feeds on lichens on various trees, in the 
spring ; and the moth appears from the end of May to July. 
CYBOSIA, Hutsner. 
The type of this group has been united by Mr. Stephens with Setina, (Philea) from which it differs in having 
larger palpi, and opake wings, which give it more the habit of the true Lithosiz ; from which it differs not only
