18 TORTRICINA. 



clothed with coarse fuscous scales on a white ground. Marginal 

 scales fuscous, with paler bases. Cilia whitish, sometimes pale grey. 

 Abdomen dark fuscous, the tuft dull straw-colour. $> Exp. al. 

 10-11 lin. 



This beautiful species is tolerably abundant and constant in 

 its general appearance. The Scotch specimens are mostly much 

 darker than the southern ones, constituting the var. E. sub- 

 fasciana. E.ferruginea is an extension of the same variety, but 

 darker and more evenly coloured. 



The imago is somewhat plentiful round London and in the 

 south of England, especially near Dover. It is taken also in 

 the north of England, in Scotland, and at Newtonlimavady, co. 

 Deny, in Ireland. Its flight is sluggish, and it may be taken 

 on the wing at dusk. 



The larva is green, and is supposed to live through the winter. 

 It has been bred by Mr. Harding (vide Entom. Weekly Intell. 

 vol. i. p. 62) ; and, from the perfect insect being mostly taken 

 among Hazel, may not that be its food-plant ? 



Genus V. BRACHYT.ENIA, STEPHENS, MSS. 



Antennae clothed above with scales, pubescent beneath. Palpi 

 longer than the head ; the apical joint conspicuous and exposed, 

 minute, oval, densely clothed with short scales ; middle joint four 

 times the length of the apical, curved, very stout, thickening from 

 before the middle, clothed beneath with long scales; basal joint 

 short and stout. Maxillae as long as the palpi. Thorax stout, 

 tufted behind. Anterior wings scarcely twice as long as broad ; 

 costa regularly arcuated ; apex obtuse ; apical margin slightly sub- 

 truncate ; dorsal margin concave. Posterior wings ample, ovoid ; 

 apical margin concave. Abdomen slender, tufted in both sexes. 



This genus was instituted by the late J. F. Stephens to 'sepa- 

 rate the two species included in it from the Antithesis, to which 

 they are so closely allied as scarcely to be separable from them. 

 The venation of the wings in the two genera is identical ; but 

 there are minor structural differences, and the wings are much 

 less deflexed in repose than in the latter genus. The abbre- 

 viated or interrupted central fascia readily distinguishes them 

 from the true Antithesis. 



The species above alluded to may be arranged thus : 



A. With the central fascia abruptly abbreviated . . . Species 1 



B. With the central fascia attaining the dorsal margin, 



but interrupted in the middle . . . . . . . Species 2
