variety of Acosmetia caliginosa, Haworth goes on to say, " Corpus 

 paulo gracilius quam in ultimo (lutescens) et also magis oblongse." 

 Both lutescens and rufa are slender bodied Noctuce, and were formerly 

 by our older British, authors classified together in the genus Acosmetia. 

 There is no doubt, I think, that the synonymy should stand as : — 



rufa, Haw., 1803, Newm., Stdgr. 



despecta, Tr., Hb.-Gey., Sta., Guenee. 



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 : — " Alis rufescentibus seu griseo atomosis, lineola 

 obliqua fusca apicis, punctoque minutissimo albo basi stigmatis postici. 

 Stigmata ordinaria fere omnino obliterata." In Guenee's original 

 description of extranea, which is much longer, the only point of differ- 

 ence is that he lays more stress on the species being more strongly 

 powdered with black scales (vide Guenee's " Noctuelites," vol. v, pp. 

 77 and 78). Any one 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 synonymy should therefore be : — • 



Leucania unipuncta, Haw., 1803. 



extranea, Gn., Newm., Stdgr. 



Nonagria neurica, Hb., = arundineta, Schmidt. 



In Stainton's " Manual," vol. i, p. 193, we find the Norfolk and 

 Cambridge Nonagria in question described under the name of neurica. 

 In Newman's "British Moths" it is described under the name of 

 arundineta. Dr. Staudinger, in his " Catalogue," 1871, separates 

 neurica, Hb., specifically from arundineta, Schmidt, and refers our 

 British specimens to arundineta, which he treats as a variety of 

 Treitschke's dark form dissoluta. I have been lately working at 

 Tliibner, and there is not the remotest doubt that our paler specimens 

 are identical with Hiibner's figure 381, neurica. Some of the speci- 

 mens sent me by Mr. Warren are exactly like his figure, except in 

 colour, which is dull brown and not reddish as in our forms, but there 

 can be no doubt about its being our insect in its palest forms. Schmidt 

 discriminates between his arundineta and Hiibner's neurica as being 

 "more robust" (a vague. difference it seems to me), and the under- 

 side spotted (i. e., without a central spot on each wing). As Htibuer
