114 TORTRICINA. 



rately stout, three times as long as the apical. Maxillae not so long 

 as the palpi. Thorax stout, ovate. Anterior wings : length nearly 

 three times the width ; costa arcuated, the costal fold extending to 

 one-third from the base ; apex acute ; apical margin entire, oblique ; 

 dorsal margin rounded. The costal vein reaches to the middle of the 

 costa ; the subcostal nervures equidistant. Posterior wings acute at 

 the apex ; apical margin slightly concave. Abdomen slender, and 

 tufted in the tf ; stout and obtuse at the apex in the $ . 



The only species at present forming this genus was formerly 

 placed by the late J. F. Stephens, in his ' Illustrations/ amongst 

 the Hedyce (Ant idea), and subsequently by M. Guenee among 

 P&discae (with him synonymous with Pcecilochroma) , a position 

 which it certainly could not maintain; consequently Mr. Ste- 

 phens, when compiling his Museum Catalogue of the British 

 Tortrices, separated it, and assigned to it a previous name of 

 GueneVs (Cartella), which is here adopted. The ground of 

 separation was doubtless the folded costa. 



1. bilunana, Haw. Alis anticis albis ; cinereo- aut pallide fulvo- 

 nebulosis ; costa punctis nigris ; maculis duabus nigris dorsalibus ; 

 posticis cinereo -fuscis. $ Exp. al. 7-8 lin. 



Head and face yellowish white, sometimes cream-colour. Eyes 

 black. Palpi : above dirty white, grey or dusky at the sides, 

 white beneath and between. AntennaB dirty white above, fuscous 

 beneath. Thorax and patagia chalk-white. Anterior wings chalk- 

 white, with umber-brown markings in shades. The costa is widely 

 streaked throughout with dilute umber, and in the centre is some- 

 times a suffused cloud, followed by a very faint indication of a fascia 

 towards the anal angle. On the dorsal margin, one-third from the 

 base, is an oblique mark, extending to the middle of the wing ; its 

 posterior edge undulated and concave, of intense umber, softening 

 rapidly towards the base ; near the anal angle is another mark, paler 

 in colour, maculated with dark spots ; a few dots and streaks are 

 disposed over the surface and on the dorsal margin. In some speci- 

 mens the disk is suffused with very dilute umber clouds. Apical scales 

 and cilia white. Posterior wings pale fuscous, darkest at the apex. 

 Marginal scales fuscous, with straw-coloured bases. Cilia varying 

 from straw-colour to grey. Abdomen fuscous, the caudal tuft pale 

 drab. $ Exp, al. 6-71 lin. 



This is rather a common species, but slightly variable in the 

 intensity of its markings. Rather larger than Hedya Paykul- 

 liana, the typical form of which it much resembles. It is distin- 

 guished from it, however, by the paler ground-colour of the 

 anterior wings, the less distinct, irregular, and less produced
