YPOXOMEUTID.E.-^YPONOMEUTA. 241 



Caterpillar black, with yellowish dorsal and lateral lines: it feeds on the 

 nettle, &c. and the imago appears in June. 



The specimen of this rare and beautiful species that is in the 

 British Museum collection was found in June 1812, by an assiduous 

 collector of the name of Sharp in a chalk-pit near Dareiith wood, 

 and I possess a second that occurred near Gravesend.
