 ii. 323. 



Expansion of the wings 3 lines. Head black. Forehead shining, silvery white. 

 Palpi silvery white. Antennae black. Thorax golden orange. Abdomen dark fus- 

 cous, rufous at the extremity. Legs and tarsi silvery gray. Anterior wings bright 

 golden orange, with a short, silvery, basal streak, margined with black : on the costa 

 are three somewhat triangular silvery spots, the first a little before the middle, the se- 

 cond a little beyond the middle, and the third near the apex ; on the inner margin are 

 two silvery spots, the first opposite the first costal spot, the second intermediate be- 

 tween the second and third costal spots ; all these spots are margined interiorly with 

 black. At the extreme apex is an oval black spot, contiguous to which, towards the 

 anal angle, is a small silvery spot. In some specimens there is a small silvery spot on 

 the inner margin near the base ; cilia pale. Posterior wings fuscous, with paler cilia. 



This species is very scarce in this country, but several were taken last August off 

 beech-trees, near Tunbridge Wells, by Mr. Weir. 



Zeller says of this species that " it flies near Vienna in May, on whitethorn, in 

 company with Kleemannella, scarce. Heyden reared this species near Frankfort-on- 

 the-Maine, in May, June and July, from caterpillars off oaks." 



This insect, which has hitherto been called in this country the cydoniella of Fab., 

 most certainly does not answer to his description, for Fabricius says, " Anterior wings 

 golden, with a line at the base, and eight very white marginal spots disposed in pairs." 

 Now there are only five marginal white spots (the sixth spot is not marginal), and 

 though the first two form a pair, the other inner marginal spot is intermediate between 

 the costal spots. Duponchel has figured as the cydoniella of Fabricius an insect 

 which appears referrible to pomonella, and Zeller refers doubtingly Fabricius' insect 

 to his pomifoliella. 



Haworth unfortunately only copies the Fabrician description ; but in his descrip- 

 tion of mespilella, he says, " very like cydoniella," so that I doubt much whether he 

 intended our insect ; besides he says, " it varies with the wings much paler, perhaps 

 only in old specimens." Now I have not yet seen a pale specimen of lautella, so that 

 this renders it still more probable that the inject intended by Haworth is not lautella.
