212 MANDIBULATA. TllICHOPTERA. 



freckled with brown, having a conspicuous clear oblique transparent spot in 

 the middle of the disc, a second irregular one between that and the apex, 

 frequently united to the former ; the hinder margin also pale, with three 

 distinct brown spots towards the apex, and a patch of the same hue on the 

 anal angle ; some of the inner nervures are deeply freckled with blackish- 

 brown, and the stigma is usually deep fuscous ; posterior wings very trans- 

 parent and iridescent, with the apex ochreous, varied with brown : — female 

 with the anterior wings of a more uniform tint, faintly freckled with pale 

 brown, having a narrovv oblique spot on the disc, and a second, generaDy 

 remote, and somewhat indistinct and irregular towards the apex, the hinder 

 margin with the anal angle and three spots towards the costa brown; stigma 

 pitchy-brown ; posterior wings transparent, with a pale uniform brownish 

 spot on the apex ; legs in both sexes pale tawny, with black spines. 



Lira, ornatus. Stepk. Catal. 323. No. 3731, var. <J. 



Rather larger, with the anterior wings paler, less deeply freckled with fuscous, 

 but having a very distinct lunate transparent discoidal spot ; stigma pale 

 fuscous ; a triangular blotch of a pitchy hue at the base of the inner margin ; 

 the costa prettily freckled with brown; posterior wings with the apex 

 ochreous, faintly varied with brown. 



Lim. diaphanus. Steph. Catal. 323. JVo. 3730, var. $ . 



Less than the former ; the anterior wings pale ochreous, very faintly freckled 

 with a deeper tint, leaving only a broad oblique transparent blotch on the 

 disc ; the stigma and three spots on the hinder margin faintly pitchy ; 

 posterior wings with the apex unvaried pale ochreous-brown. 



Lim. cognatus. ISteph. Catal. 323. No. 3729, var. ?. 



With the anterior wings pale ochreous, faintly mottled with a darker tint, leaving 

 a very narrow oblique transparent line on the disc, and a faint one towards 

 the hinder margin, which last has three rather indistinct pitchy spots 

 towards the apex, and a tinge of the same hue on the hinder angle ; stigma 

 pale pitchy-brown. 



An extremely variable species : in some examples the stigma on the anterior 

 wings is wholly wanting, in others it is very, distinct, and in some partly 

 obliterated; the tranverse nervures are occasionally edged with deep 

 fuscous. 



The larva (according to Pictet) is large, has the head and two first segments 

 dull uniform brown, divided with black streaks, the followmg segment pale, 

 with some blackish spots ; the abdomen pale greenish ; legs brown. 



This variable species is far from uncommon, throughout the metro- 

 politan district, during the early summer months : it also occurs in 

 the New Forest, Devonshire, Norfolk, Suffolk, near Dover, in Scot- 

 land, &c.
