AND THEIR TRANSFORMATIONS. jqj 



LITHOSIA, Fabricius. (SETINA, Sciirank.) 

 Wo are now arrived at an extensive group of plain and uniformly coloured insects, distinguished by the 

 length and narrowness of their f„ro wings, which are convoluted in repose. The antenna.^ 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 si.xtecn feet ; they form an oval cocoon.

Synonvmes.— /,i</iosm/a?,'a, Fabririiis ; Haworth ; Stephens; Wood, lud. Eut., pi. 8, fig. 91). 

 This species measures rather less than U 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 wines 

 still paler coloured, beneath paler. The body is pale ochre-coloured. Taken, but rarely, in the Kentish woods. 



SPECIES 2.— LITHOSIA PLUMBEOLATA. Plate XX., Fig. 7. 

 Synonymes. — Lithosia plumbeotata, Su-plicns; WoikI, IiiJ. Kut. pi. 8, fig. 103. (Nee. Litho^ia pliimlicola, lUibncr). 

 Mr Stephens describes the species as similar to, but rather larger than L. Griseola ; the head bright luteous ; 

 antenmu, thorax, and abdomen cinereous ; anterior wings of a pale lead-coloured ash, with the costa narrowly 

 edged with yellowish, fringe flavesccnt ; posterior wings above cinereous-yellow, beneath paler ; fringe straw- 

 coloured. Found near London.

 Lithosia aurantia^ llawortli. 



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 antenna; and abdomen dusky, except at the li]i 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 tlie middle and hind parts of 



the body. It feeds in May and June on several species of Finns, 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. Plate XX., Fig. 10. 



Synonymes. — Bombyx Griseola, Hubner; Oelisenheimcr ; Boisduval ; Hawoitli ; Stephens ; Wood, Ind. Ent. pi. 8. fig. 102. 

 This very dull-coloured insect varies from fifteen to eighteen lines in expanse; the antennas are dirty buff; 

 the head whitish ; the thora.x 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.

This species measures about 1| inch in the expanse of the fore wings; it is most nearly allied to L. tlava, 

 but has the fore wings of a deeper rich colour than in that insect, and more inclining to buff; the hind wings
