24 THE MOTHS OF THE BRITISH ISLES. 



last-named Sussex locality and Eastbourne in one direction, 

 and Lewes in the other, one or more specimens of the type or 

 of ab. glabra have occurred from time to time. Mr. E. P. Sharp 

 took a specimen of glabra at Eastbourne on Nov. 30, 1913- 

 The species has also been noted from Hampshire (New Forest 

 and Bournemouth), Somerset, Devon, Kent (Darenth), and 

 Hertfordshire (St. Albans). The most recent records from 

 Hants refer to two captures at Bournemouth in 1902, 



The Chestnut {Orrhodia {Conistrd) vaccinit). 



Figure 3 on Plate 11 represents this species in its typical 

 form, which is of a dark chestnut colour, and almost without 

 markings. The brighter red modification of this form has 

 been named ab. rufa^ Tutt ; while another assuming the blacker 

 hue of O. ligula has been described as ab. utiicolor^ Tutt. In 

 some of the redder forms the cross lines are dark and con- 

 spicuous, thus approaching ab. spadtcea, Hiibner, which has 

 distinct black lines as seen in Fig. 6. It should be noted that 

 the figure just referred to is from a German specimen, as I was 

 unable to obtain a suitable British example of the form. 

 Another far more frequent form of this variable species is ab. 

 tnixta, Stand. (Fig. 4), in which the ground colour is ochreous, 

 more or less tinged with red ; the more yellow-coloured ex- 

 amples of this form have been separated under the name 

 ochrea^ Tutt. Figure 5 shows a form that is rather less common 

 than either of those just adverted to ; the specimen is one of a 

 short series from Kent that I have labelled ab. suffusa^ Tutt ; 

 as will be noticed, the band on the outer area is in strong con- 

 trast to the rest of the fore wings. Apart from the above and 

 other named forms, there is considerable aberration in the 

 markings, and more especially as regards the stigmata. The 

 lower extremity of the reniform is usually black or blackish, 

 but it may be very faint or entirely absent, and as a contrast
