XXVIII. On the British Species of the Genus Gelechia of 

 Zeller. By J. W. Douglas, Esq. {continued from p. 108.) 



[Read 5th January, 1852.] 



Sp. 91. Fumosella. 



G.fumosella, H. Doubl. (in litt.) 



Alas anticae fusco-nigrae, punctis tribus (2 — 1) elevatis atris, 

 ciliis fuscescentibus. x\lae posticae latae, griseo-fuscae. 



Expansion of wings 10g lines. 



Head, palpi, antennae and thorax concolorous with the anterior 

 wings, which are fuscous-black ; before the middle are two large 

 raised black spots, placed close together, one above the other, 

 and one other beyond the middle ; cilia greyish brown, with 

 a black line extending through the centre, from the apex to the 

 posterior angle of the wing. Posterior wings broad, with obtuse 

 apices ; cilia greyish fuscous. 



Closely allied to G. jEthiops, but apparently distinct, being in 

 every way larger, the upper wings being brown-black, instead of 

 jet-black, and the posterior darker than in that species. 



A single specimen taken in 1851, in Perthshire, by Mr. Weaver, 

 is in the collection of Mr. Doubleday. 



Sp. 92. Politella. 



G. politella, (Doug.) Sta. (Cat. Supp. p. 4.) 



Alae anticae nitentes, olivaceo-brunneae, punctis tribus discoida- 

 libus nigris. Alae posticae latae, griseo-brunneae. Exp. alar. 

 6 lin. Mas. 



Alae anticae angustae, ochraceae, capite palpisque concoloribus. 

 Exp. alar. 5 lin. Fcem. 



Head, palpi and antennae concolorous with the anterior wings. 

 Anterior wings shining, light olive-brown, three very small black 

 dots on the disk, as in G. terrella, and a row of black dots round 

 the apex. Posterior wings greyish brown. Male. 



Head, thorax and palpi concolorous with the anterior wings; 

 antennae annulated brown and ochreous alternately. Anterior 

 wings ochreous, marked as in the male, but shorter and nar- 

 rower. (In one of the two females I have before me, the anterior 

 wings are contracted on the costa beyond the middle, expanding 

 again towards the apex.) Posterior wings greyish brown, with an 

 ochreous tinge, especially on the cilia. Female.
