British Species of the Genus Gelechia of Zeller. 103 



Found by Mr. Bentley on the trunks of poplars. 



Haworth's specimen is in the collection of the Entomological 

 Society. 



Differs from G.junctella in the greater paleness of the base, in 

 the angular form and larger size of the blotch before the middle, 

 in the absence of the rufous patch beyond, in the slighter whitish 

 fascia, and the broader margin of griseous to the apex. 



Differs from G. marmorea in being less, in the paler base and 

 darker inner margin, in the form and distinctness of the blotch 

 before the middle, and in the dark colour not being continued 

 along the costa. 



Haworth places it next to contigua and sequax, and says, " Haec 

 et duae praecedentes forte mera varietates sunt, sed characteribus 

 valde diversis." I do not see so much resemblance to sequax ; 

 but it is more like contigua, from which it differs in being smaller, 

 in the costal blotch being very different in form, not touching 

 the costa in its whole length, but only at its origin ; in the whitish 

 hinder fascia not being expanded on the costa, and in the absence 

 of a rufous tinge on the inner margin. 



Sp. 84. Junctella, mihi. 



Alse anticae griseo-albidae, puncto humerali, fascia lata abbreviata 

 obliqua ante, altera punctorum forma pone medium, atris ; 

 tertiaque recta albida : apice atro. Alae posticae griseae. 



Expansion of wings 4| — 5 lines. 



Head shining bronze ; palpi griseous, terminal joint black ; an- 

 tennae annulated black and white. Anterior wings greyish- white, 

 a black humeral spot, a thick black sub-linear fascia or blotch 

 reaching obliquely to the groove, before the middle ; beyond the 

 centre an oblique row of black dots disposed as a slender fascia, 

 joined to which and reaching to a whitish fascia which stretches 

 quite across the wing, is an angular rufous blotch ; apex black, 

 bordered with griseous ; cilia griseous. Posterior wings and cilia 

 griseous. 



Found by Mr. Bouchard in August on trunks of oaks, in com- 

 pany with G. Hiibneri, to which species this bears considerable 

 resemblance in the disposition of the markings ; but the general 

 darker colour and the nearly straight whitish fascia are so dif- 

 ferent that I cannot consider it identical therewith. There is also 

 great resemblance to the preceding G. maculiferella, from which 

 however it may be known at first sight by the first fascia or blotch
