TORTRICINA. 247 



of the attenuated form, and nearly straight costa, of the anterior 

 wings of the cf , which are also immaculate, whilst in the $ they 

 are fasciated. The perfect insects frequent moist situations, and 

 are tolerably common in such localities. 



1. ictericana, Haw. Alis anticis marls albidis, fulvo-irroratis ; 

 posticis griseis ; fcemince albidis nebulis fasciisque pallide fuscis ; 

 posticis griseis. Exp. al. 8-1 0^ lin. 



Head pale ochreous. Face greyish. Eyes black. Palpi longer than 

 the head, yellowish drab. Antennae grey. Thorax and patagia pale 

 ochreous, darker in front. Anterior wings glossy, unicolorous, pale 

 ochreous. Apical scales slightly paler. Cilia still paler. Posterior 

 wings grey, with a slight pearly lustre, and yellowish at the apex. 

 Marginal scales pale straw-colour. Cilia paler. Abdomen glossy, 

 dark grey ; the apex straw-colour. $ Exp. al. 9-10 lin. Anterior 

 wings glossy, pale drab, with dusky ochreous markings. At the base 

 is a rhomboid patch (sometimes produced at the angle) extending 

 one-fourth along the costa, and about the same distance along the 

 dorsal margin ; pale at its origin, merging into dusky ochreous pos- 

 teriorly. At the middle of the costa commences a similar- coloured, 

 but rather darker fascia, sharply denned, and deeply biangulate on 

 its anterior edge, and attaining the anal angle ; its posterior edge 

 straighter and suffusing, and from the middle branching off to the 

 apex, enclosing a palish space on the costa. The apical margin 

 dusky ochreous, sometimes reticulated in the subapical region. 

 The costa and pale portions of the wing streaked with pale, wavy, 

 transverse lines. 



A very common species in damp meadows, and similar situa- 

 tions. Both the 6 and $ are variable in size and colour. The 

 former sex resembles Tortrix icterana, but is distinguished from 

 it by its nearly straight costa, and longer narrower wings. 



The ? nearly approaches, in appearance, toCnephasia alternella, 

 but the ground-colour of the wings and the markings have an 

 ochreous tinge, and are paler. 



The imago appears in June and July. It was formerly taken 

 in the fields round Bow and Limehouse, and still occurs in the 

 Isle of Dogs, Hackney Marshes, at Charlton, Lewisham, South- 

 end, Hastings, near Dover, in Cheshire, &c. 



The larva feeds on Aster tripoleum, and other plants, and is 

 most probably polyphagous. 



Genus II. CNEPHASIA, CURTIS. 



Palpi longer than the head, remote, ascending, densely clothed 

 with scales; basal joint drooping, curved, pyriform ; apical same
