68 TORTRICINA. 



ochreous (sometimes grey), iron-grey at the apical and anal angles. 

 Posterior wings deep fuscous. Marginal scales deep fuscous. Cilia 

 white. Abdomen dark fuscous above, pale grey beneath. $ Exp. 

 al. 6-9 lin. 



A common insect, subject to much variation in the colour of 

 the anterior wings, and also in the size. The var. L. obsoletana, 

 as figured in ' Wood's Index Entomologicus/ pi. 3i. f. 1035, is 

 very rare, and has the anterior wings of a dull smoky-black, in- 

 clining to umber, with the silvery markings more numerous, and 

 disposed over the surface in streaks and spots. 



The imago appears at the end of June and in July, in woody 

 places, among Oaks, Elms, &c., throughout the south of 

 England, and in the Midland Counties; in Scotland, in the 

 vicinity of Edinburgh. 



The pupa is pitchy -black, and measures about 5i lines in 

 length. 



The larva feeds on the Sycamore, Maple, Oak, Mountain - 

 ash, Elm, and other trees. 



Genus IV. NOTOCELIA, HUB. 



Palpi twice as long as the head; basal joint stout, truncate; 

 apical minute, obovate, terminating in a point, not so long as the 

 basal ; middle stout, curved, ascending, thickest beyond the centre, 

 four times as long as the apical. Maxilla? slender, as long as the 

 palpi. Thorax rather slender, ovate, not crested. Anterior wings : 

 length equals twice the breadth. Costa regularly arcuated in both 

 sexes ; in the <$ with a fold extending to the middle ; apex obtuse ; 

 apical margin slightly concave, dorsal margin rounded. The costal 

 vein does not reach beyond the fold. The discoidal cell extends 

 scarcely beyond the middle of the wing. The subcostal nervures are 

 remote, the first being inserted near the base ; the submedian nervure 

 inserted nearly opposite the second subcostal one. Posterior wings : 

 apex obtuse, concave on the apical margin ; dorsal margin entire. 

 Abdomen slender, and with a tuft at the apex in the $ ; stout in 

 the $. 



There is likewise only one known European species in this 

 genus, which in the habit of the larva presents considerable pecu- 

 liarities. It is minutely described below, and well figured with 

 details in Fischer von Roslerstamm's 'Microlepidopterologie/ 

 pi. 91. By Guenee this genus is placed at the commencement 

 of his 5th tribe (Sericoridi) ; but as it possesses a costal fold in 

 form and quantity similar to that which obtains in Pardia and 

 Spilonota, it is now brought in proximity to those genera.
