TORTRICINA. 143 



brown spot, bordered with white ; the apical margin edged with dark 

 brown. Apical scales and cilia straw-colour, the latter slightly dusky, 

 both interrupted by a fine brown streak running through them below 

 the apex. Posterior wings pale grey, with a pearly lustre. Marginal 

 scales and cilia paler grey, the former with the bases pale straw- 

 colour. Abdomen fuscous grey, the caudal tuft drab. $ Exp. al. 

 lin. 



A very common species, and tolerably constant, both as to 

 size and colouring ; distinguishable from its congeners by the 

 longitudinal brown streak upon the anterior wings. 



The imago appears in May and June, flying in the evening 

 over heathy places. It occurs at Birch, Darenth, and Dulwich 

 Woods, Plumstead and Wimbledon Commons, New Forest, and 

 throughout the country, especially in the north of England. 



In the North the larva feeds on Myrica Gale (the Sweet Gale), 

 but we are not aware on what other plants it feeds in the South, 

 where the Sweet Gale does not grow.

Head dark fuscous. Face slightly paler. Eyes black. Palpi : 

 above, at the sides, and beneath, dull fuscous, pale grey at the base 

 between. Antennae umber, paler beneath. Thorax dark fuscous. 

 Patagia slightly paler. Anterior wings drab, streaked and marked 

 with golden brown ; at the base is a streaked brown patch, extend- 

 ing one-fourth along the costa and nearly to the middle of the dorsal 

 margin, its posterior edge rounded (in some specimens it is much 

 angulated). From the middle of the costa to within the anal angle 

 on the dorsal margin proceeds an angulated fascia, edged posteriorly 

 with white. The ocelloid patch is grey, more or less clouded with 

 fuscous and white, and streaked with lustrous scales. The costa is 

 sharply and thickly marked with geminated streaks, those beyond 

 the middle being white, lustrous, and most distinct ; they are more 

 or less produced along the apical portion of the wing. The apical 

 spot is distinct, and below it is a white patch, with two (sometimes 

 only one) black streaks running through it. The pale portions of 

 the wing much clouded with fuscous, and the dorsal margin regu- 

 larly maculated with brown. The apical margin is black, in some 

 specimens brown. Apical scales yellowish. Cilia fuscous, variegated 

 with brown, sometimes ochreous. Posterior wings shining pale 

 fuscous, darkest at the apex. Marginal scales straw-colour. Cilia 

 very pale grey, with a fuscous tinge. Abdomen fuscous, the caudal 

 tuft drab. $ Exp. al. 6 lin. Head, face, and palpi white ; anterior 

 wings white, the basal patch not attaining the costal margin ; other-
