122 HAUSTELLATA. LEPI DOI'TERA. 



Sp. Pinastii. Linnc. — Don, ix. pi. 296. Steph. Catal. 



Wings cinereous, anterior obsoletely undulated with brownish, with three un- 

 equal diverging black lines on the disc, and an oblique, slightly bent, dusky 

 one at the apex; posterior immaculate, the base rather paler than the margin; 

 the fringe of all the wings white, clouded with cinereous: sides of the head 

 and thorax white, the former dusky at the top, the coUar united to a furcate 

 dash of the same hue passing to the hinder part of the thorax, interior to the 

 white edge : abdomen with a narrow black dorsal line, and the sides with 

 alternate spots of black and white. 



Caterpillar in its first skin entirely yellow ; the second green, with yellow stripes; 

 third deeper green, with three longitudinal lemon-yellow lines on each side; 

 and finally of a rich green, with a brown dorsal Une ; the sides with two deep 

 yellow ones : the anterior legs and the first segment of the body are yellow, the 

 latter spotted with black ; the horn, which was previously straight, becomes 

 curved and black : it feeds on various species of pine, such as the Pint Abies, 

 »ijlvestris, Strohits, &c. The chrysalis is gray brown, changing to maroon : 

 the tongue-sheath is short. 



Evidently a rare insect in the south, but more frequent in Scot- 

 land ; one specimen was taken in June, near Colney Hatch Wood, 

 about thirty years ag-o, and a second in the neighbourhood of 

 Eslier; which are the only English specimens that have come to 

 my knowledge. " In Rivelston-wood, near Edinburgh, once taken 

 by myself, and several times by Mr. Wilson of the College." — 

 Dr. Leach. 



Sp. 7. plebeia. Alis g7-iscis, puncio medio alba, abdominis lateribus albis nigro 

 margiuatis. — Fab. (Exp. alar. 3 unc. 1 lin.) 



Sp. plebeia. Fahricius. Sieph. Cutal. 



Anterior wings griseous, with several indistinct black lines, and a central white 

 spot ; posterior obsoletely fasciated with fuscous upon a lighter ground : the 

 fringe of all white spotted with brown : abdomen above griseous, with a 

 black dorsal line, the sides white margined with black ; beneath white, with 

 a row of fuscous dots. 



Dr. Leach obtained a specimen of this insect (which is now in the British 

 Museum) from Dr. Lettsom's cabinet, and I procured a second from another 

 old collection, reputed to contain indigenous productions only; but as the 

 species is American, I think it highly probable that both the above were 

 placed in the respective cabinets in lieu of Sp. Pinastri, in accordance with 

 the bad practice to v^hich I have so frequently been compelled to allude, and 

 the evil tendency of which I have more particularly pointed out in my ob- 

 servations subjoined to the following species.
