characterized species of British Moths. 113 
met with this imsect but once, and then in abundance on the 
paling round Dover Castle in July 1829. I suspect it is only a 
strong variety of C. octomaculana, as some of my specimens ap- 
proach that insect. 
14. 10. C. rectifasciana, Haw. I am not satisfied that this 
is the insect figured by Hiibner (pl. 38. f. 238) under the name 
of T. hybridana: it is larger and darker, and the markings have 
a different character ; indeed it reminds me more of a variety of 
T. comitana. 
Mr. Doubleday having applied my generic name to that por- 
tion of the group which is not typical, it becomes necessary to 
repeat, that the type of Cnephasia is a species abundant on elm- 
trees, the 7. logiana of Haworth, which im 1826, when I esta- 
blished its characters, was believed to be synonymous with the 
Linnean species, as well as with the 7. pascuana of Hibner, 
pl. 16. f. 99. The name Sciaphila, which Mr. Doubleday has 
substituted for Cnephasia, was not published by Treitschke until 
1829, and could not therefore be applied to my group, even had 
it not been preoccupied by Schénherr for a genus of Curculionide 
four years before Treitschke adopted it. It may be as well to 
correct the spelling of Hiibner’s name, which in his letterpress 
is pascuana, but by an error of the engraver the s has been con- 
verted into an 7, making the unmeaning word pasiuana, and pas- 
sana of Doubleday’s list. 
15. Genus 960, 1. Orthotenia (Euchromia, Step.) formosana, 
Curt. B. E. fol. 364. This was described by me in 183], not as 
the T. formosana of Hiibner as indicated by Mr. Doubleday, a 
species I am unacquainted with, as well as his 7. flammeana, 
neither of which can I find in the Index to Hiibner’s works nor 
in Treitschke. ° 
16. 13. O. Arbutana, Hib. pl. 31. f. 195. Mr. Dale feels 
confident this is the 7. Arbutella of the Linnzan cabinet. 
17. 7. O. alternana, Curt. ib. : Daleana, Doub., was also de- 
scribed in ‘ Brit. Ent.’ in 1831, where I adopted the names in 
the Ist ed. of my ‘ Guide,’ and not of the ‘ Wiener Verzeichniss,’ 
where I am unable to find 7° alternana ; and even if it be there, 
I must protest against the superseding of established specific 
names, unless the name has been employed in the same group 
previously. If such be the case in the present instance, I fully 
approve of the name of my friend, which Mr. Doubleday pro- 
poses. 
18. 8. O. gramineana, Curt. ib., also described on the above 
page of ‘Brit. Ent.’ At that time I stated it was “ most allied
