VARIETIES OF NOCTURE IN THE BRITISH ISLANDS. 223 



data. Newman figures both sexes of it in bis ' British Moths,' p. 

 274, where it is also treated as a distinct si^ecies. Staudinger 

 treats it as syi!on3'mous with extrema, Hb., which seems to me 

 imi^ossible. This variety had not been taken in Britain for 

 manj' years, until I took it at Deal in 1885, 1886, and 1887. 

 Mr. Warren writes : — " Some twelve years ago, Albert Houghton 

 and myself each took a concolor on June 26th. Both were much 

 worn. He threw his, a female, away ; I kept mine, a male, and 

 it was sold wdth the rest of my Macros " {in litt.). 



The following seems to me a fair summary of the forms 

 described by previous authors : — 



1 . A very dark red form, with a transverse row of dots =fulva, 

 Hb. 



2. A red form, unspotted = var. injgmbva, Haw. 



3. An ochreous red, or brownish red form, with dots = var. 

 neui'ica, St. 



4. A reddish-ochreous form, without dots = viLY.Jluxa, Tr. 



5. An ochreous or wliitish form, with dots = var. concolor, Gn. 



6. An ochreous or whitish form, without dots = var. 2^Mida, 

 St. 



Tajy'mostola, Ld., hellmanni, Evers. 



The tj'pe of this species is described by Staudinger as " pale, 

 greyish or reddish straw-colour." Guenee's var. a. is undoubtedly 

 the type, he describes it as " less red, more powdered with grey, 

 reniform stigma more yellowish than red ; inferior wings darker." 

 — 'Noctuelles,' vol. v., pp. 104, 105. 



Var. saturata, Stdgr. — This is a dark reddish variety. Staud- 

 inger says of it, " Obscurior, alis anterioribus ssepius totis rufis." 

 Newman, in liis ' British IMoths,' p. 275, has described apparently 

 only the red form. Guenee also treats this form as his type. 

 The two forms occur in the same localities and appear equally 

 common. 



Tapinostola, Och., elyini, Tr. 



Treitschke's original doscrij)tion of the type is as follows : — 

 " alis anticis solito longioribus pallide flavis atomis fuscis ad- 

 spersis serie externa striolarum fuscarum " (' Die Schmet. von 

 Europa,' vol. v., p. 294). This species varies but little ; the 

 females are generally paler than the males, and the latter sex are 

 in some sj)ecimens more strongly powdered with brownish or 

 fuscous scales than in others.
