(inner) margin, and two at the base of the cilia; face, abdomen, and legs,

Of this species I am also unaware of the locality. 



Genus IV.— NARYCIA mihL 



AntenncB with the basal joint pilose and much incrassated, the remainder 

 furnished on each side with long hairs : maxillary palpi drooping, very 

 pilose, rather short : head transverse-ovate, pilose in front : eyes moderate, 

 lateral, scarcely prominent: thorax ovate: wings strongly deflexed during 

 repose ; anterior elongate-elliptic, obtusely rounded at the apex, which is 

 furnished with short scaly cilia ; nervures very indistinct ; posterior smaller, 

 somewhat ovate, furnished with longer cilia : abdomen shortish, stout, some- 

 what cylindric : legs stoutish, anterior tibiae with a single spur at the inner 

 apex; intermediate with a pair, and posterior with a pair at the apex, and. 

 a second pair in the middle. 



The distinctly pectinated filiform antennae of the insects of this 

 genus at once serve to distinguish them from the other Trichoptera, 

 from which, like Acentropus, they also differ in having the wings 

 clothed with scale-like hairs ; but, unHke that genus, their legs are 

 provided with ample spurs, and the sides of the thorax are not fur- 

 nished with tippets.

Narycia elegans. Steph. Nomen. 2d edit. col. 118. 



Shining brown-black: antenna very pilose, silvery-grey, with the tips of the 

 articulations black, radii fuscous ; anterior wings black, varied with brown, 

 and with numerous yellowish and ochreous dots, of a golden tint, especially 

 on the margins, the inner one having two large blotches of that colour 

 towards the middle; posterior wings fuscous, with darker ciha; legs 

 silvery-grey, varied with brown-black. 

 Twice taken on palings at the Hermitage, South Lambeth, at the 



end of June. 



Family III.— RHYACOPHILIDtE mihi. 



Antennae slender, moderate, rarely exceeding the length of the wings : maxillary 

 palpi alike in the sexes and 5-jointed, slightly pilose, the two basal joints 

 short, the 2nd being about as long as the 1st, the 3rd elongate, 4th and 5th 

 somewhat shorter, this last being ovoid : ivings narrow, elongate, slightly
