LEPIDOPTERA. 157 



tifully, but having been misled as to the name of the insect 

 he bred from them, the occurrence of this insect as British 

 was not announced. 



The sharply-defined whitish-grey base of the dull reddish- 

 brown anterior wings readily allows of the complete identifi- 

 cation of the insect, and now that it has been found on the 

 Sea-holly, a plant by no means uncommon on our coast 

 sand-hills, we may anticipate its general diffusion in our col- 

 lections. The larva should be looked for in May. 



Gelechia muscosella, Z. This insect, though a little 

 broader in the wing, is so similar to G. cuneatella, Dough, 

 that I had strongly advocated their being the same species. 

 The sight, however, of fine specimens of both species re- 

 ceived from Professor Zeller has satisfied me of their dis- 

 tinctness. 



Cuneatella has the posterior wings darker and with the 

 apex more prolonged than in Muscosella. In 3Iuscosella, a 

 little before the middle, we see on the disc of the anterior 

 wings a black dot, ringed with whitish : of this there is in 

 Cuneatella no trace, but that portion of the wing is on the 

 contrary occupied by an elongate black spot, which is sepa- 

 rated from another similar black spot by a small trapezoidal 

 greyish-white spot. 



Muscosella has, it is true, a single black streak on the 

 disc, but it is longer and not so broad as the markings in 

 Cuneatella, and, in fine specimens, there seems to be another 

 whitish-ringed black dot at the end of it. 



Professor Zeller writes me word that Cuneatella frequents 

 Salix alba; Muscosella occurs amongst Sal'ix caprea. 



The Hon. Thos. De Grey met with three specimens of 

 Gelechia muscosella at Wicken Fen. Professor Zeller writes 

 me that he has also recoo^nized the veritable Muscosella
