 yellow, becoming darker with age ; dorsal area usually 



* I consider Curtis's insect to be Lecanium hesperidum ('Gardener's 

 Chronicle/ 1843, p. 517, figs. 1-6). Many of his specimens were longer and 

 more convex than typical hesperidum characters due to the exigency of the 

 insects on the twigs.
