 terior wings. Further materials are necessary before constituting 

 a special genus for its reception.

Madeira {Wollaston). 



This supposed species rests solely on the authority of a single 

 $ example submitted, to Hagen, but which was lost in the pro- 

 cess of working-out. I have seen no species of Agrai/lea from 

 the islands. The colour, as described, agrees with that of Stac- 

 toiia atra. 



Hydeoptila (?), n. sp. 



Madeira : between Cama dos Lobos and Cabo Girao, 1780 feet, 

 20th November ; cliff below Sant' Anna, 500 feet, 26th November, 

 {Uafon, 2d). 



Canaries : near Teror, 1600 feet, 9th December, and near San 

 Mateo, about 4600 feet, 11th December, Grand Canary ; in the 

 botanic garden, Orotava, and a valley N.E. of Santa Cruz, 

 1300 feet, 25th December, Tenerifte {Eaton, many examples). 



This insect will probably form a new genus. Although closely 

 allied to Hydroptila (restricted), and with apparently the same 

 neuration of the wings, it differs in the absence of the elevated 

 lobes on the posterior portion of the head. I believe the same 

 generic form is known to me from the Erench Pyrenees. 



The specific identity of the Madeiran and Canarian examples 

 appears probable ; but the materials for the former are barely 

 sufficient.

* The minute insects comprising this family require the strongest possible 

 daylight for satisfactory elucidation. The month (November) in which this 

 portion of the paper was -written was the least favourable in this respect. In 

 order, therefore, no longer to delay the publication of the paper (most of 

 which has been written for many months), minute description of the Hydro- 

 ptilidffi is reserved for the forthcoming additional Supplement to my 'Eevisiou 

 and Synopsis of the Trichoptera of the European Fauna.'
