66 HAUStELLATA. — LEriDOPTERA. 



doptera Britannica, from two specimens captured by P. W. Wat- 

 son, Esq. near Beverley, Yorkshire. Many years, however, passed 

 away without other specimens occurring-, and the London cabinets 

 were destitnte of this species until the learned author of the above 

 work discovered it in profusion in a marshy situation near Cotting- 

 ham, in the above county, and supplied his friends therewith. It 

 jias of late years been found in Scotland and Wales, and appears 

 to be not uncommon in some parts of Cumberland; and I am 

 assured by Mr. Wailes that it occurs in plenty on damp heaths, in 

 Northumberland, in the beginning of July, varying from my figure 

 Ij to figure 3 : in fact, it appears to be not an uncommon northern 

 species.

Anterior wings griseous-tawny^ with two blind ocelli towards the tip ; posterior 

 brown, with a broad whitish stripe on the inner edge, and a minute blind 

 ocellus towards the anal angle : beneath, the anterior wings are tawny-brown, 

 with the base brown, ash-coloured at the tips, with an abbreviated transverse 

 Avhitish band posteriorly, between which and the hinder margin are two remote 

 ocelli, with an obsolete white pupil and black iris, and cinctured with white : 

 the posterior wings at the base are dusky, externally dentate, and terminated 

 by an irregular whitish fascia, behind which they are cinereous, with six 

 ocelli, of which three are very small and nearly obUterate<l, and all are sur- 

 rounded by a white circle. 



Var. ^.* With the white fascia on the posterior wings beneath scarcely conti- 

 nuous. 



Mr. Haworth, with his wonted acumen, ventured to describe this 

 insect as distinct from the former, ujion the examination of three 

 specimens only of the two supposed species ; for such alone can I 

 imagine them to be, notwithstanding I have separated them above 

 — the chief distinction, according to Mr. Haworth, consisting in 

 the iniinterrupted white fascia on the under surface of the posterior 

 wings, and which, if allowed to constitute the diagnostic of the 



* This, the preceding, and the following insects vary similarly in the pre- 

 sence and obliteration of the oceUi. I shall, therefore, merely notice (under 

 Hi. Polydama and Davus) such varieties as appear peculiar to the respective 

 species, observing that the former insect has usually larger and more distinct 

 ocelli than Hi. Iphis.
