132 NEW BRITISH TINEINA. 



tion of a fascia. Unfortunately, the distinctness of the fascia 

 varies much in different specimens of Heliquella, so that 

 sometimes it is scarcely visible. 



There seems, hoAvever, a difference of habit in the two 

 species ; Salaciella, as far as I know, always frequents dry 

 localities, and generally is only met with singly ; on the 17th 

 June, 1858, I captured twelve specimens of SalacieUa, near 

 Guildford, amongst Trifolium arvense and Humex ace- 

 tosella ; otherwise I have only met with it singly ; and 

 Zeller says of it, that near Glogau he has often found it 

 in the driest fir and birch woods, but always singly. 



In a box of insects sent me for determination by the Hon. 

 T. de Grey, M.P., I found a specimen of O. reliquella, the 

 first British specimen I had seen. An inquiry, as to the 

 locality and date of its capture, produced the following 

 reply : 



*' I have seen three specimens, and three only, of Opos- 

 tega reliq^iella here [near Thetford] ; I took one last year, 

 in an open grass-plot on the outskirts of a wood. I caught 

 a second, in exactly the same spot, about the middle of 

 June (11th ?) this year, in my hat, but it escaped j and the 

 third (which you saw), I beat from mixed growth in a 

 grass-ride in the woods, about 150 yards from where I 

 took the other two : this last specimen was taken early in 

 August, as far as I can remember." 



Shortly afterwards, I received from Mr. P. C. Worm.ald, 



notice of some captures of Tineina in 1867, and was 

 much struck with the following entry : 



'^ Opostcfja salacidlaj near Hampstead, August 6th, 

 swarming on a gas-lamp." The idea of Salaciella swarm- 

 ing seemed to me so novel, that I wrote for further infor- 

 mation, and begged a sight of the specimens ; one of them.
