56 [August, 



eolorous plate, having a few brown spots on eacli side ; fore-legs green. 

 It feeds on Populus nigra, P. canadensis, &c. 



The larva of JiostiJis, Steph., on the contrary, is chocolate-brown 

 with a rosy tint, and with three interrupted yellowish lines, that on 

 the side so narrow that the ground colour seems to form a broad dark 

 band. The spiracular line broad, rosy, bordered above and below by 

 a yellow line. Head shining black, with two pale streaks ; second 

 segment black on the sides, yellowish in the middle. Pore-legs black. 

 The larva might also be described as greenish-yellow, with a dorsal 

 and t.vo fine chocolate-brown sub-dorsal lines, below which is a very 

 broad band of the same colour, which extends to the head, spiracular 

 line .... It feeds only on Fopulus tremula. 



True rhenella, Zk., and adelphella, F. v. E-., do not appear to have 

 been found in England. 1 find both rhenella and hostilis near Paris.- 



JPempelia hetulce, Goze. — The synonymy given in Dr. AYocke's 

 Catalogue appears correct, and tristrigella, Steph., is certainly this 

 insect. The larva feeds on birch, and has been described several times. 



Pempelia paJumhella, S.Y. — In Dr. Wocke's Catalogue, alhariella, 

 H.-S., fig. 37, is quoted as a synonym, but in error, for the figure very 

 well represents Zeller's albariella. The larva has been described by 

 von Hornig as feeding on Poly gal a cJiamcshuxus, and in England it 

 might feed on P. vulgaris, but the true food plant of palumleUa is 

 Erica cinerea. M. de Joannis found it plentifully on this heath in 

 Jersey last spring.
