226 MANDIBULATA. TRICHOPTERA. 



Larva with the head and thorax brown, the following segment with four black 

 dots ; the abdomen ochreous ; legs brown. 



I am compelled to change the name originally proposed in my Catalogue for 

 this species, as the name lineola is employed by Villers, and that of elegans, 

 given by Pictet, was previously used to designate a very different insect by 

 Curtis, who, with ill-judged taste, has confused the nomenclature of the 

 Trichoptera considerably, by adopting many of the same names as I had 

 previously employed to very different insects, as may be seen by the syno- 

 nymes. 



Also rare : found within the metropolitan district, in the autumn. 



Sp. 41. prseustus. Fuscus, infra ockraceus, alts anticis pallide ochraceis, margine 

 postico maculd apicali stigmateqve ustulatis. (Long. corp. 3 lin. ; Exp. Alar. 

 6 lin.) 



Lim. prseustus. Steph. Catal. 3^3. No. 3720. 



Fuscous, beneath ochreous : antennae brownish ; anterior wings pale ochreous, 

 with a triangular blotch at the anal angle, an obscure spot on the apex 

 towards the costa, and the stigma umbre brown; posterior wings whitish, 

 hyaline, iridescent, with the apex faintly tinted with ochreous; legs pale 

 ochreous, with dusky spines. 



Found, but rarely, near London, in July. 



Sp. 42. flavus? Ochraceus, thoracis dorso abdominegue brunneis, alis anticis 

 Jiavis vittis duabus indistinctis longitudinalibus brunneis. (Long. corp. 5 lin.; 

 Exp. Alar. 10—11 lin.)

Ochreous : back of the thorax and the abdomen brown ; anterior wings rusty 

 yellowish-ochre, with the nervures concolorous, the inner margin and a 

 portion of the hinder one thickly freckled with brown, forming two indistinct 

 longitudinal streaks, and having an ovate immaculate patch on the hinder 

 margin ; posterior wings hyaline, pale, immaculate, with the apex faintly 

 tinged with ochreous ; legs and antennae bright tawny, the former with 

 black spines. 



A very variable species : in some examples the anterior wings are very much 

 freckled with brown ; in others they are almost immaculate. 



Larva with the head and two anterior segments brown, the following ochreous, 

 with four dusky dots, the abdomen pale ochreous, with long cilia; legs 

 brown. 



Not uncommon, in June, in the neighbourhood of the metropolis, 

 and apparently very abundant in December : taken likewise in the 

 New Forest.
