ON BRITISH SPECIES OF EUPCECILIA. 87 



Sp. 6. MACULOSANA, Hawortli (1812). maculosana. Haw., 

 Steph., Doub. Cat., Stainton, Wilk. 

 Not uncommon in early summer in many places. A closely 

 allied continental species, j)ur^atana of Treitschke, is doubt- 

 fully distinct. 



Sp. 7. ANGUSTANA, Hiibner (1801). angustana, Hiib., 



Treitsch., Herr.-Schf. fig. 94, et Auct. Biit. ; = 



cruentanGj Frol., Herr.-Schf., Heinem. 



This is an abundant species. Schmid, according to Ross- 



ler, bred it from the flowers of Achillea millefolium and 



also from those of Origanum vulgar e. But it doubtlessly 



affects many other plants. It is remarkably variable in size. 



Sp. 8. cuRVisTRiGANA, Wilkinson (1859). airvistrigana, 

 Wilk., Stainton, Doub. Cat. 

 Very similar to angustana, but sufficiently distinct ac- 

 cording to the characters pointed out by Wilkinson; accord- 

 ing to Heinemann it differs in the neuration, and is thus 

 placed by him in another section. He writes me that it 

 feeds in the flowers of Solidago virgaurea; Rossler also 

 attributes it to that plant, but erroneously refers the name to 

 Haworth, and apparently equally incorrectly gives Jiavi- 

 scapulana of Herr.-Schf. as a synonym. According to 

 Heinemann the latter species feeds on Chenopodium, Curvi- 

 strigana is yet rare and local. 



Sp. 9. AMBiGUELLA, Hiibner (1801). ambiguella (et-ana), 



Hiib., Steph., Doub. Cat., Stainton, Wilk., Heinem., 



Staud. and Wock.; = roserana, Tr., Herr.-Schf. 



To my mind there is yet some uncertainty as to whether
