&4 VARIETIES 



The hind wings are whitish, slightly tinged with ochreous at the 

 base, and a little darker on the outer margin. The nervures are also 

 slightly darker, and there are four distinct small black spots on the 

 nervures " (' Catalogue Systematique des Lepidopteres de F Andalousie,' 

 PI. viii., fig. 2). 



Leucania, Och., turca, L. 



Vol. i., p. 33. Leucania turca var. grandis, Btl. If all the Japanese 

 forms of grandis are to be included under one varietal name, the term 

 will necessarily be a very comprehensive one. Thanks to the courtesy 

 of Mr. Doncaster, I saw a very large consignment of the species from 

 Japan, and must express my doubt as to the wisdom of uniting it 

 specifically with turca as we know it. The great mass of the speci- 

 mens were more or less distinctly yellow-ochreous ; a few were very 

 deeply and richly ferruginous, whilst scarcely a specimen was of the 

 shade of our British specimens. There appears to be no distinct character 

 by means of which the two forms may be differentiated, but the two 

 forms are so distinct in superficial general appearance, that one may 

 reasonably express doubt as to their identity. 



Leucania, Och., unipuncta, Haw. 



Vol. i., p. 33. Of the nomenclature of this species I wrote 

 some time ago : " Leucania unipuncta, Haw. = extranea, Gn. There 

 seems to be no doubt that the latter name, which is in use in all our 

 books and lists, will have to give way to Haworth's earlier name. 

 Haworth's description (' Lepidoptera Britannica,' p, 174, No. 37), is 

 very distinct. He writes: 'Alis rufescentibus seu griseo atomosis 

 lineola obliqua fusca apicis, punctoque minutissimo albo basi stigmatis 

 postici. Stigmata ordinaria fero omnino obliterata.' In Guenee's 

 original description of extranea, which is much longer, the only point 

 of difference is that he lays more stress on the species being more 

 strongly powdered with black scales (vide Guenee's ' Noctuelites,' vol. 

 v., pp. 77-78). Anyone who will compare Haworth's description 

 with that of Guenee, or with that in the " Entomologist,' vol. xxi., p. 

 138, will, I believe, be at once convinced of their identity. The 

 synonomy should therefore be : 



Leucania unipuncta, Haw., 1803. 



extranea, Gn., Newm., Stdgr. 

 (' Entomologist's Monthly Magazine,' vol. xxv., p. 56). 



Leucania, Och., loreyi, Dup. 



Vol. i., p. 35. The original description of this species is as 

 follows : " This NOCTUA resembles pallens in shape and size. Its 

 superior wings above are also of the same colour and striated very 

 finely between the nervures ; but they differ in that this species has a 

 white triangular dot placed in the middle of a brown longitudinal dash 

 which starts from the base, and, gradually rising, crosses the wing 

 almost to the apex, losing itself in the reddish tint of the outer edge. 

 A small black dot is also to be noticed, placed between the white dot 

 just spoken of and the corselet of the thorax, as well as a row of in- 

 distinctly marked red dots parallel with the hind margin. Lastly, 

 the fringe is grey. The inferior wings are as white above as below, 

 with a mother of pearl reflection. The undersides of the fore wings 

 are of a reddish- white and finely dotted on the borders. The head is
