200 TOETRICINA. 



guished from all other British Tortrices by the two large yelloiu 

 spots on each of the anterior wings. By M. Guenee it is placed 

 in his Catalogue under the generic name " Trycheris" but, as it 

 is unaccompanied by any characters, we have elected the prior 

 one of Hiibner's. The larva appears to be unknown. Does it 

 feed on the roots of the Umbelliferse ? 



1 . aurana, Fabr. Alis anticis brunneis ; macula magna quadrata 

 margine dorsali, altera apicem versus rotunda aurantiacis ; posticis 

 fuscis. tf Exp. al. 5 lin. 



Head and face ashy grey. Eyes black. Palpi as long as the 

 head. AntennaB dark brown. Thorax and patagia ashy grey. An- 

 terior wings glossy, pale chocolate-brown, with a large orange- 

 coloured, somewhat quadrate, blotch on the dorsal margin, and an- 

 other in the apical angle of similar size and colour, but of a slightly 

 richer tint, and of roundish form. Apical scales dark dusky brown. 

 Cilia iron grey. Posterior wings and marginal scales dull fuscous, 

 the latter with pale yellow bases. Cilia pale fuscous. Abdomen 

 dull brown. Exp. al. 5 lin. Colours and markings as in the <$ , 

 but more dilute. 



A rather common species on umbelliferous flowers, and toler- 

 ably constant in size and colour ; sometimes, however, the dorsal 

 spot on the anterior wings is produced into a triangular blotch. 



The imago appears in June and July, flying at midday in the 

 sunshine. It occurs at Darenth Wood, Kipley, Hertford, near 

 Croydon, and a few other places round London ; in Gloucester- 

 shire, Cheshire, and Lancashire ; abundant in Yorkshire ; also at 

 Renfrew, and in the vicinity of Edinburgh ; generally distributed 

 in Ireland. 



Genus VI. EPHIPPIPHORA, DUPONCHEL. 



Palpi slightly longer than the head, remote, ascending. Basal 

 joint slender, curving upwards, truncate ; apical obovate, slender, 

 not so long as the basal ; middle not stouter than the basal, curved 

 ascending, isometric, three times as long as the apical. Maxillae as 

 long as the palpi. Thorax ovate, moderately stout. Anterior wings 

 considerably longer than twice the width. Costa regularly arcuated. 

 Apex obtuse. Apical margin rounded, dorsal margin straight. 

 The discoidal cell lies in the upper half of the wing, extends about 

 two-thirds its length, and receives an internal nervure inserted to- 

 wards the second subcostal nervure, which crosses to the second 

 apical nervure. Subcostal nervures not equidistant. The costal 

 vein attains the margin before the middle. Posterior wings : apex
