British Species of the Genus Gelechia of Zeller. 105 



tify if one be taken alone ; but when seen together and in quantity 

 they seem to me, independently of the variation of time of appear- 

 ance and the circumstances pertaining to different localities, to be 

 naturally divisible into distinct species. 



Sp. 86. Basaltinella. 



G. Basaltinella, Z. 

 Re. domestica, var. /3, Haw. 



Head and thorax concolorous with the anterior wings ; palpi 

 griseous, terminal joint black ; antennae black, faintly annulated 

 with white. Anterior wings ashy-fuscous, with an apical yellow- 

 ish fascia, a spot at the base of the costa, and four black ones 

 placed as in G. domestica, the two central ones being, as in that 

 species, frequently confluent. Posterior wings griseous. 



Several specimens taken by Mr. Bedell, last June, out of old 

 thatch at Addington. 



Under the head of G. domestica (vol. v. p. 198) I have without 

 doubt given G. Basaltinella as a synonym, but an examination of 

 recent specimens has led me to think with Herr Zeller that it is 

 distinct. The whole insect is very much darker than domestica, 

 although the size and markings are the same ; it agrees exactly 

 with Haworth's var. j3, which is preserved in the collection of the 

 Entomological Society, and of which he observes, " Forte propria 

 species." 



Sp. 87. Boreella, mihi. 



Alae anticae latae, obtusae, griseo-fuscaa, punctis, tribus disco, 

 atris, lined brevi medio, fasciaque postica acute bi-angulatd, 

 albidis. Alae posticae griseae. 



Expansion of wings 6 J lines. 



Head and thorax concolorous with the anterior wings ; palpi 

 of the same hue, terminal joint black ; antennae black. Anterior 

 wings broad, obtuse, grey- fuscous ; in the groove a black spot, 

 another above and beyond, but both before the middle ; a third 

 beyond the middle in a line with the second, from which it is 

 divided by a linear whitish streak; a posterior, narrow whitish 

 fascia, acutely bi-angulated in the centre, beyond this the apex is 

 darker than the rest of the wing, bordered on the hinder margin 

 with a black line, and on the costa with black dots ; cilia griseous ; 

 Posterior wings griseous. 



A single specimen, taken by Mr. Stainton, 14th July, 1850, on 

 boggy ground on the shores of the Holy Loch, Argyleshire.
