TORTRICINA. 13 



slightly hairy, and with the segments edged transversely with 

 yellow. 



The cocoon is whitish, boat- shaped, resembling the cocoon of 

 Earias clorana, but is longer. 



Genus II. AMPHISA, CURTIS. 



Antennae strongly pectinated and pilose in the tf , faintly so in 

 the $ , inserted on the crown of the head over the eyes. Palpi 

 much longer than the head, approximating, porrected horizontally, 

 thickly clothed with scales ; basal joint minute, drooping ; middle 

 horizontal, robust, especially towards its apex, five times as long as 

 the apical ; apical slender, cylindrical, as long as the basal, slightly 

 depending. Maxilla3 short. Thorax slender, ovate. Anterior wings 

 elongate-triangular in the <$ , lanceolate in the $ . In the tf the 

 costa is obtusely arched at the base, less so in the $ ; the apex 

 slightly produced ; apical margin oblique, slightly concave ; dorsal 

 margin rounded. The discoidal cell reaches rather beyond the middle 

 of the wing ; the three subcostal nervures nearly equidistant ; the 

 apical vein gives out five nervures, of which the first is furcate, one 

 branch reaching the margin above, the other below the apex. Poste- 

 rior wings : apex obtuse, with the apical margin scarcely concave. 

 Abdomen slender, tufted in the <$ . 



This genus was established by Mr. Curtis, and may be distin- 

 guished by the antennae, which are pectinated in both sexes, a 

 character which does not occur elsewhere in the family, so far as 

 is at present known. The palpi offer no peculiarities in their 

 structure, being of the normal form, and the maxillae do not 

 exceed those organs in length. In Curtis' s ' British Ento- 

 mology/ pi. 209, the nenration of the anterior wing is figured, 

 in which the discoidal cell is represented as being open at the 

 apex; but, upon a careful investigation of this part of the 

 subject, we have not met with this peculiarity throughout the 

 family. 



There are two British species, which may be thus distin- 

 guished : 



A. Anterior wings with the ground-colour sulphur-yellow Species 1 



B. Anterior wings with the ground-colour grey . . . Species 2 



1 . Gerningiana, SchifF. Alis anticis ochraceo-flavis ; subreticulatis 

 (aliquando sine reticulationc) ; fascia media obliqua maculaque 

 postica costali brunneo-fuscescentibus ; posticis violaceo-griseis.
