THE MERE WAINSCOT. 30I 



September, and is found in fens and marshy ground pretty well 

 all over the British Isles, including the Hebrides. 



The Concolorous {TaJ)inostola extrevia). 



This species (Plate 146, Fig. 3) was at one time subsequent 

 to 1844, when it was first discovered in Yaxley Fen, not at all 

 scarce in that locality and in other fens in Huntingdonshire and 

 Cambridgeshire. It then disappeared from all its old haunts, 

 some of which were destroyed ; but a few years since it was 

 met with again in Hunts, and apparently not uncommonly. 



Bond's Wainscot {Tapiiwstola bondii). 



The whitish moth shown on Plate 146, Fig. 4, was first taken 

 at Folkestone, Kent, by Dr. Knaggs, in 1859, and named and 

 described by him in 1861. It still occurs in that locality and 

 also on the Devon and Dorsetshire coast, the known localities 

 being Charmouth, Lyme Regis, and Sidmouth. 



The caterpillar is dirty white in colour inclining to brownish 

 at each end ; a whitish line along the middle of the back ; head 

 brown. Feeds from August to June in stems of Fcstuca 

 ancndiiiacea. The moth flies in June and July. 



The Mere Wainscot {Tapinostola hellnianni). 



Present localities for this reddish species (Plate 146, Figs, i, 2) 

 are Wicken and Chippenham fens, Chatteris and Whittlesford, 

 in Cambridgeshire ; Monk's Wood in Hunts. Formerly Yaxley, 

 where it was first taken in 1847, used to be a noted locality, but 

 the insect disappeared when the fen was drained. It has been 

 reported from Norfolk (Yarmouth), Lincolnshire, Devonshire 

 (Dartmoor), and Hertfordshire (Hitchin), chiefly in odd speci- 

 mens. The caterpillar has been described by Hofmann as 

 yellowish-white, or reddish above and paler beneath ; plate
