158 TORTRICINA. 



geminated streaks. The posterior wings are large and broad, of 

 pale colour, have a peculiar glossy appearance, with the basal 

 angle enlarged. In repose they always sit very close to the plane 

 of position, and hold their wings but very slightly deflexed, 

 especially their posterior portion. Peronea Hastiana sits with 

 its anterior wings overlapping. 



Larvae for the most part known ; they feed between united 

 leaves. 



This family contains five genera, which are thus tabulated : 



A. Anterior wings without tufts of elevated 

 scales on tJieir upper surface. 



a. Palpi twice as long as the head. 



a a. With the middle joint four times as 



long as the apical 1. CHEIMATOPHILA. 



B. Anterior wings with tufts of elevated scales 

 on their upper surface. 



b. With the costa clothed roughly with scales 

 at the base and apex, and slightly incised 

 in the middle. 



c. Palpi longer than the head. 



d. With the middle joint three times as 



long as the apical 2. OXYGRAPHA. 



c c. Palpi twice as long as the head. 



d d. With the middle joint three times 



as long as the apical 3. PERONEA. 



d d d. With the middle joint four times 



as long as the apical 4. PARAMESIA. 



b b. With the costa roughly clothed withscales 

 at the base and apex, and MUCH incised in 

 the middle. 



dddd. Palpi with the middle joint four 



times as long as the apical . . .5. TERAS. 



Genus I. CHEIMATOPHILA, STEPHENS. 



Palpi twice as long as the head, remote, slightly drooping, clothed 

 with scales beneath to the base, and very thickly so towards the apex ; 

 basal joint drooping, pyriform, truncate ; apical obovate, longer than 

 the basal ; middle very stout, thickened before, at and beyond the 

 centre, curved, four times as long as the apical. Maxillae short. 

 Thorax slender, ovate. Anterior wings without tufts of elevated 

 scales, length exceeding twice the width. Costa arcuated, obtuse 

 towards the base ; apex slightly produced ; apical and dorsal margins 

 rounded. The costal vein reaches the margin at the middle, subcostal
