deep grey colour ; at Loggan it is beautifully white, with the 

 characteristic marks dark." 



(3. var. semivirga, mihi. — The same ground colour as in the 

 type, but the space between the undulated transverse line 

 parallel to the hind margin, and the hind margin, is suffused 

 with black scales, especially towards the line. This gives the 

 variety the appearance of having an exterior band, although not 

 so broadly developed as in the almost parallel varieties of psi and 

 tndens. This variety is represented in Newman's ' British 

 Moths,' fig. 3, p. 251. It may be worthy of remark that tridens 

 has only a banded variety, psi and leporina both banded and 

 suffused varieties, while the remainder of the genus have only, 

 so far as we at present know, suffused varieties. 



y. var. rosea, Engr. — Guenee describes a variety under 

 Engramelle's name " La Rose,'" as having "the superior wings 

 and abdominal incisions of a bright rose," and says of it, "this 

 charming variety is very rare." 



Acronycta, Och., aceris, L. 



Var. candelisqua, Esp. — This also is a very dark suffused 

 form, the suffusion consisting of an immense number of brown 

 scales scattered over the wings. All the markings are very 

 obscure, being almost lost in the darker ground colour, with 

 the exception of the transverse line, which shows up distinctly 

 as a series of dusky arches or curves across the wing. This 

 was also considered as a distinct species by our early lepi- 

 dopterists. Newman figured it in ' British Moths,' p. 251, second 

 figure. 



Acronycta, Och., megacephala, De Geer. 



a. var. turanica, Stdgr. — A species of this name is found in 

 Staudinger's list between eiiplirasice and ritmicis. The locality 

 given is Turkestan. Mr. Dobree writes me that this so-called 

 species "is nothing more than a light-coloured form of mega- 

 cephala from Turkestan." 



/3. var. rosea, Engr. — Guenee describes this variety as 

 follows: — "Superior wings of a pale (whitish) rose, with all 

 the markings very distinct." He also says, "this variety is 

 frequently reproduced. I have seen several examples." 



(All our British specimens of this species are darker than 

 those from the South of Europe and Asia.)
