156 TORTRICINA. 



rior wings : ground-colour orange, thickly suffused with bright pale 

 reddish brown, a snow-white trigonate patch, like a shark's tooth, on 

 the middle of the costa, frequently edged with black scales, and with 

 pale-violet lustred fasciae and markings ; these latter are visible only 

 when viewed obliquely, and are thus disposed : a cloud at the base, 

 followed by a broad, nearly isometric fascia before the costal patch, 

 from the apex of which proceeds another but irregular fascia towards 

 the anal angle, mostly furcate on the dorsal margin ; beyond this is 

 a narrow, nearly straight fascia, extending from the costa to the 

 apical margin, just above the anal angle, succeeded by a few spots in 

 the apical angle. The apical portion of the wing sometimes irrorated 

 with black scales. Apical scales slightly ferruginous, with orange 

 bases, cilia rich straw-colour, both becoming iron-grey at the anal 

 angle. Posterior wings pale grey, clothed with coarse fuscous scales. 

 Marginal scales dull grey, with paler bases. Cilia dirty white. Ab- 

 domen and caudal tuft dull straw-colour. $ Exp. al. 6^7 lin. 

 Anterior wings marked and coloured like the <$ , but with the violet 

 lustred fasciae, &c., usually more sharply denned. 



A common insect, not variable, and easily distinguished by 

 the snow-white trigonate patch in the middle of the costa. 



The imago appears in June and July in tolerable plenty in 

 gardens and hedges, in the metropolitan district ; near Hertford ; 

 in Cheshire, and other parts of the country. It occurs also in 

 Scotland in the vicinity of Edinburgh, and near Belfast in 

 Ireland. 



The larva feeds on the Rose, Apple and Pear, and perhaps 

 upon the Sloe ; it is of a yellow colour, with the head hazel or 

 pale reddish brown, and about 5 lines in length. 



Genus VIII. HEMEROSIA, STEPHENS. 



Antennae very stout. Palpi longer than the head, stout, approx- 

 imate, porrected horizontally ; basal joint somewhat elongate, pyri- 

 form, drooping, truncate ; apical oval, much shorter than the basal ; 

 middle ascending, as stout as the basal and thickening beyond the 

 centre, scarcely four times as long as the apical. Maxillae longer 

 than the palpi. Thorax robust, ovate. Anterior wings, length more 

 than twice the width ; costa slightly arcuated ; apex obtuse. Apical 

 and dorsal margins rounded. The discoidal cell is situated in the 

 upper half of the wing and extends two-thirds its length : subcostal 

 nervures equidistant. Posterior wings ample, apex subacute ; apical 

 and dorsal margins entire. Abdomen moderately stout in both sexes, 

 tufted in the < .
