(1 ill each year) ; Ipswicli, 1895-6 (2 and 1) ; Wilniiiigton, Kent, 

 1899-1900 (3 and 5) ; Market, Downham, Norfolk, 1907-11 (4 in 

 five years) ; Thames Valley, 1907-1914, the records for this period 

 are consecutive only for the whole area covered by the term 

 " Thames Valley," they are not consecutive for any one locality 

 included therein. 



The actual counties from which the species has been recorded are 

 Sussex, Kent, Surrey, Middlesex, Essex, Cambridge, Suffolk, Norfolk, 

 and Gloucester. Su,ssex and Gloucester records refer to single 

 examples which were probably chance visitors. There is every 

 probability that in all the other counties the species does or did breed 



Ocellaris Bkli., is the usual form of the insect taken here and on 

 the Continent. Ab. lineago is of rare occurence in England, but is 

 taken more freely on the Continent ; it is certainly not, as Barrett 

 suggests following Staudinger, confined to the Altai Mountains. Ab. 

 intermedia, first recorded from Bognor in 1894, occurs as about one to 

 six or seven of the type and must be regarded at present as being 

 almost confined to the Thames Valley, as only two appear to have 

 been taken outside this district in 22 years. Ab. gilvescens is, so far, 

 entirely confined to the Thames Valley; it was first recorded in 1910 

 when Messrs. Mills and Nevinson bred a few among the more usual 

 forms of the species and since then five wild examples have been 

 taken. 



In the descriptions of the various forms which follow it will be 

 seen that they fall readily into two groups :— (a) typical, and (b) gilvago- 

 like. The first contains ocellaris, abs. lineago, palleago, carneago, and 

 the Algerian forms ; the second, abs. intermedia, gilvescens, and the 

 moneta-likQ form from Eussian Asia.

Ocellaris Bkh., Ent. Mo. Mag., fig. 5. It has the size and form of Taenio- 

 campa miniosa. The ground colour of the fore-wings is a mixture of red lead 

 and grey, but paler than in miniosa, and the nervures stand oi\t distinctly as 

 light stripes. The transverse lines are very pale, darker margined (median 

 shade dark grey, sub-terminal pale, edged with a row of blackish grey dots often 

 faintly indicated or obsolete except the first above vein 6, fringe reddish 

 ochreoiis) ; stigmata bordered by a mixture of grey and pale red lead colour, 

 the lower end of the reniform with a white dot edged by black (dark grey). 

 The hind-wings white (ochreous whitish, inner marginal third fuscous-tinged). 

 Palpi grey (tinged with red). Head grey with pale reddish tinge. Antennae 

 whitish above, below pale brown (red).
