AND THEIR TRANSFORMATIONS. 101 
LITHOSIA, Faprictus. (SETINA, Scuranx.) 
We are now arrived at an extensive group of plain and uniformly coloured insects, distinguished by the 
length and narrowness of their fore wings, which are convoluted in repose. The antenne are slender and simple, 
each joint emitting two short bristles, The spiral tongue is long and convoluted ; the palpi very short and two- 
jointed ; the terminal joint very minute ; the body slender. The caterpillars are long, cylindrical, and more or 
less hairy, with sixteen feet ; they form an oval cocoon. 
SPECIES 1.—LITHOSIA FLAVA. Puate XX., Fre. 6. 
Synonymes.—Lithosia flava, Fabricius ; Haworth ; Stephens ; Wood, Ind. Ent., pl. 8, fig. 99. 
This species measures rather less than 13 inch in the expanse of the fore wings. The general and uniform 
colour of the insect is very pale yellow inclining to buff; the fore wings without the paler costa, the hind wings 
still paler coloured, beneath paler. The body is pale ochre-coloured. Taken, but rarely, in the Kentish woods. 

SPECIES 2.—LITHOSIA PLUMBEOLATA. Puarte XX., Fic. 7. , 
Synonymes.—Lithosia plumbeolata, Stephens; Wood, Ind. Ent. pl. 8, fig. 103. (Nec. Lithosia plumbeola, Hiibner). 
Mr. Stephens describes the species as similar to, but rather larger than L. Griseola; the head bright luteous ; 
antennx, thorax, and abdomen cinereous; anterior wings of a pale lead-coloured ash, with the costa narrowly 
edged with yellowish, fringe flavescent ; posterior wings above cinereous-yellow, beneath paler ; fringe straw- 
coloured. Found near London. 

SPECIES 3.—LITHOSIA AUREOLA. Puare’XX., Fie. 8, 9. 
Synonymes.— Bombyx Aureola, Hiibner; Ochsenheimer; Stephens, Noctua cincta, Esper.

Lithosia aurantia, Haworth. 
Setina unita, Schrank; Esper ; Lliger. 
This species varies in expanse from ten to fourteen lines; the head, thorax, extremity of the abdomen, and 
fore wings, are of a “ decidedly rich orange,” the latter being broader than in the other species ; the hind wings 
paler yellowish orange ; the antennae and abdomen dusky, except at the tip of the latter; the fringe of all the 
wings orange. Beneath, the fore wings have a large discoidal patch of brown. The caterpillar is black, with 
two orange-coloured stripes on the back spotted with red, and some white spots on the middle and hind parts of 
the body. It feeds in May and June on several species of Pinus, and the moth appears in July, but is rare in 
this country, frequenting places where fir-trees are planted, in the south of England. 

SPECIES 4.—LITHOSIA GRISEOLA, Puare XX., Fie. 10. 
Synonymes.— Bombyx Griseola, Hiibner ; Ochsenheimer ; Boisduval ; Haworth ; Stephens ; Wood, Ind. Ent. pl. 8. fig. 102. 
This very dull-coloured insect varies from fifteen to eighteen lines in expanse; the antenna are dirty buff ; 
the head whitish ; the thorax and fore wings of a pale dusky flesh-colour, having a silky gloss and a narrow 
yellowish anterior edging ; the abdomen and hind wings are of a paler dusky buff. I took this species in 
company with Mr. Stephens, in a lane near Ripley, in considerable numbers on the 13th August, 1826. 
Mr. Stephens has also taken it near Hertford. 

SPECIES 5.—LITHOSIA GILVYEOLA. Puate XX., Fie. 11. 
Svnonymes.—Lithosia Gilveola, Stephens ; Ochsenheimer? Wood, Ind. Ent. pl. 8, fig. oi: 
Bombyx cinereola, Hubner. 
This species measures about 14 inch in the expanse of the fore wings; it is most nearly allied to L. flava, 
but has the fore wings of a deeper rich colour than in that insect, and more inclining to buff; the hind wings
