a Genus of Tineidce. 119 



inner margin, it is broadest at the base, but continually decreases in 

 breadth, terminating a little before the apex of the costal triangle ; 

 apical cilia reddish yellow ; inner marginal cilia pale grey. 



Posterior wings shining grey, with grey cilia. 



In var. b, the yellow of the anterior wings is of a deeper colour 

 than usual, and appears to shade off gradually into the red, in- 

 stead of having sharply defined margins; and along the costa in 

 the middle of the triangle are two very faint brownish spots. 



Common among oaks in May, June and August. My specimen 

 of var. b was taken on Dartford Heath fence, April 19th, 1848. 



The objection to retaining the Fabrician name for this insect 

 lies in the words " Alae posticse auratce." 



I certainly think this must be Thunberg's Swederella (under 

 which name a specimen was sent by Bohemann to Zeller), and if 

 so, the name Franckella must fall. I leave the matter in the 

 hands of the next writer on this species. 



Sp. 2. Oneratella, Zeller. (PI. XIV. fig. 12.) 



Alis anticis brunneo-rufis, postice rlavido-mixtis, triangulo costae 

 stramineo, plicam superante. 



Oneratella, Zel., Linn. Ent. ii. 317. 



Not nearly allied to any other species of the genus ; in the pale 

 colour of the trigonal mark it resembles Franckella, but the form 

 of the mark is quite different, not being prolonged along the 

 costa. 



Expansion of the wings 6 lines. 



Head reddish brown ; face pale straw-yellow ; palpi pale yellow, 

 the terminal joint brown before the apex ; antennae pale yellow, 

 with dark brown annulations ; thorax reddish brown, with a fine 

 yellow line along the middle ; abdomen brownish grey, beneath 

 yellowish ; the four anterior legs have the femora and tibiae 

 reddish-brown, the latter with a white spot on their middle, tarsi 

 shining white at the ends of the joints, with a brown spot ; pos- 

 terior legs dirty, shining, reddish white, tarsi the same, with the 

 ends of the joints darker. 



Anterior wings reddish brown, the darkest parts are the margins 

 of the costal triangle (especially that towards the base of the 

 wing), and the inner margin towards the base ; the costal triangle 

 reaches beyond the fold of the wing, almost touching the inner 

 margin, its hinder margin is slightly angulated, turning towards 

 the base of the wing ; it is pale straw yellow, and there are a few 

 red-brown spots along the costa. At the base of the wing is a
