Caterpillar dusky, with a broad reil band on the back, dividetl by a narrow black 

 line, and white spots on the sides, with another red line beneath ; it is grega- 

 rious and polyphagous, feeding on white and black thorn, elm, oak, fruit-trees, 

 &c. in June; the pupa is dusky, and the imago appears at tlie end of July or 

 beginning of August. 



Very abundant in certain years, but of late it has been rather 

 scarce near London : it occurs in various parts of the country.

Caterpillar dusky, with two red lines on the back, and an interrupted white 

 streak on each side, with white lateral fascicles: it feeds gregariously on 

 various plants, especially the white-thorn, and in some years its increase is 

 enormous. In 17 89, prayers t were ordered to be read in all the churches, to 

 avert the supposed impending calamicy, from the vast nmnber of larvne that 

 abounded in that year, having despoiled so many trees of their foUage, and, 

 it was feared, would extirpate the gi'owing corn and grass. It changes to a 

 dusky pupa, with paler rings : the imago appears in August 



Not very common of late years near London, but more frequent 

 at Gravesend and Southend, where many specimens were captured 

 during the past season. " Common near Bottislram." — Rev. L.

* The names of tliis and the preceiling insect have hitherto been confused by 

 English writers, like those of Thecla:- Pruni, and W. album ; tlie true Pa. Pruni 

 ofLinne (of which a description will be given in my catalogue), not having been 

 detected in Britain before July hist : the reputed Th. Pruni (^'cl. I. p. 77.) 

 being the Pa. W. album, Hiib. and unknown to Linne. 



t In France these larvte have so frequently appeared in such prodigious 

 numbers, to the utter defohation of the forests, as to induce the legislature to 

 promulgate several ordonnances for their destruction.
