36 PLATE CCCLXXI1I. 



This infefit is feparated from the Linneean Chryfomela 10-pun6lata 

 upon the authority of Entomologia Britannica as above quoted 

 There is much reafon to believe it a diftinct fpecies, though we cannot 

 fpeak preciiely to that effect, fince it is poffible it may prove, on fu- 

 ture obiervation, to be the female of Chryfomela lO-pun&ata, or a 

 variety of it. The two infecls refemble each other in fize, and moft 

 other particulars, the bilobate black mark, or confluent fpots on the 

 thoiax, and the colour of the mouth, and legs excepted: thofe of C. 

 10 pun6tata being black, while in our infecl, they are conftantly yellow, 

 or yellowiih-red, inclining to rufous. Several writers agree that Chry- 

 fomela 10-pun6tata, is liable to much variation : Fabricius, in parti- 

 cular, tells us, he has obferved it with both the wing-cafes deftitute 

 of the fifth, or pofterior fpot. The lower furface is black. Found 

 on the afpia and willow. 



The fmaller figures, as ufual, point out the natural fize of the infe6ls 

 reprefented in this plate.
