AND THEIR TRANSFORMATIONS. j^g 



(ENISTIS, HuBNER. (LITHOSIA, Sect, ff Boisduval.) 



I have adopted Iliibncr's name for tlie large footman-moth, having observed a character in tliat insect not 

 hitherto noticed, wliicli, in the present state of our knowledge of the classification of the night-flyino- 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 branoli 

 of the same vein pushed almost to the base of the wing. In the typical Lithosiaj (L. complana) there are only 

 two branches at the extremity of the median vein. Moreover, Boisduval has separated it from the other 

 LithosicB, ranking it as distinct as L. rubricollis.

Lithosia deplana, Pabr. (male). 

 (7Cni>:lis quadra, Hiibner, Vei-z. 



This is tlie largest species in the genus, measuring from 1} to 1 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 bein" blue- 

 black J 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-chcsnut, fir. Sec, in 

 June ; and the moth appears in July, and is a widely distributed and abundant species. 



GXOPIIRl.V, Stei'hexs. (ATOLMIS, HunNER.) 



The insect, upon which this group has been proposed, agrees with the typical Lithosire 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 w-ing, the median vein emitting three branches, the third being furcate. 



SPECIES 1.— GNOPHRIA RUBRICOLLIS. Plate XX., Fig. 20, 21.

Wood, Ind. Ent., pi. 8, fig. IOC. 



This species varies from 1 to 1} 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. 



CYBO.SIA, HuBNEE. 



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 Lithosice ; from which it differs not only
