1988 Insects. 



the disk ; cilia fuscous. Posterior wings grayish-brown, with paler cilia : thorax 

 black-brown, varied with ochre. This insect appears from the middle to the end 

 of June. 



Antithesia prcelongana, Guenee. Expansion of the wings eight lines; anterior 

 wings deep blue-blach, with an indistinct white fascia a little before the middle, which 

 has two black blotches on it, one soon after leaving the costa, the other contiguous to 

 the inner margin (which gives the insect the appearance of having a square white spot 

 on the costa, and a small white mark near the middle of the disk) ; apical portion of the 

 wing white, from near the middle of the costa to near the anal angle, with numerous 

 bluish-black clouds ; cilia bluish-black. Posterior wings fuscous, with paler cilia. 

 This is about the size of corticana, but the anterior wings are narrower ; it is not a 

 very uncommon species in the North of England and Scotland. I do not know what 

 plant it frequents : it appears early in June. 



Antithesia leucomelana, Guenee, Weaverana, Dale. Expansion of the wings 

 seven lines ; anterior wings blue-black to beyond the middle, with an interrupted 

 ochreous fascia a little before the middle ; beyond the dark portion of the wing is a 

 very conspicuous black dot placed about the middle ; apical portion of the wing 

 ochreous, with fuscous clouds ; cilia fuscescent. Posterior wings fuscous, with paler 

 cilia. A pretty and very distinct species : I have met with this in the Isle of Arran, 

 and believe it frequents the mountain sallow. 



Spilonota amcenana, Hubner. Expansion of the wings eight lines ; anterior wings 

 (in fine specimens) of a beautiful flesh colour, with the base dark fuscous to near the 

 middle, and an indistinct curved cloudy fascia a little beyond the middle, on which 

 near the inner margin is a conspicuous black blotch, forming with some black dots 

 near the hinder margin an ocellus (as in aquana), on which at the apex is a bluish 

 blotch ; the costa with numerous short fuscous streaks or dots ; cilia at the apex deep 

 blue-back, changing to fuscous, and flesh colour towards the anal angle. Posterior 

 wings gray. This insect has been taken at Sanderstead and Kiddlesdown, and also 

 on the coast by Mr. Allis, in Cumberland ; by Mr. S. Stevens, at the Isle of Portland ; 

 and by Mr. Edleston, on the Cheshire coast. 



Spilonota rusticana, Fabricius. To this species is referrible the quadrana of Ste- 

 phens, being the Scotch variety of this insect, and always much darker than the gene- 

 rality of English specimens. 



Spilonota trigeminana, Stephens. Apparently identical with argyrana, (Stephens). 

 The latter name has been used for a species of Pseudotomia, so that it will be prefer- 

 able to retain the name trigeminana. 



Pseudotomia simpliciana, Haworth. Under this name we had collected together 

 several species known and described on the continent ; it is useless to attempt descrip- 

 tions of them here, as neither by figure nor description could I render the differences 

 between the species discernible. There are probably half a dozen, or more, species 

 that we have been in the habit of calling simpliciana, but I only know the names of 

 four, viz., plumbagana, Treitsche, and senectana, ulicana, and caliginosana of 

 Guene'e. 



Pseudotomia coniferana, Ratzburgh. Expansion of the wings 5 — 6 lines. Head, 

 thorax, and anterior wings deep glossy brown black ; the costa with four short silvery 

 white streaks, the first and second indistinctly geminated, the fourth very clearly so, 

 the third quite simple; on the inner margin opposite the first streak on the costa is a 

 small silvery-white crescent, within which is a short black streak ; near the anal angle
