Sp. 19. alnifoliella, Hubner (fig. 19). 



Tinea alnifoliella, Hubner, Ti. 193. 



Elachista alnifoliella, Duponchel, xi. 526, PI. 308, fig. 2. 



Lithocolletis Rajella, Zeller, Isis, 1839. 



Lithocolletis alniella, Tischer, MSS. Zeller, Linn. Entom. i. 229, tig. 27. 



Argyromiges Blancardella, Bent. Mus. 



Expansion of the wings 4 lines. Head white, with a few dark hairs. Forehead 

 white. Palpi white. Antennas whitish, annulated with fuscous. Thorax tawny, with 

 the sides whitish. Abdomen fuscous, with the extremity paler. Legs white. Tarsi 

 white, spotted with black. Anterior wings dark tawny, with a rather broad white streak 

 at the base, four white spots on the costa, and three on the inner margin : the first 

 costal spot is long and rather triangular, and points towards the anal angle ; the other 

 three costal spots are all comma-shaped and very small : the first inner marginal spot 

 is very broad at the base, and the apex points into the middle of the second spot ; the se- 

 cond spot is, at its origin, triangular, but with its apex curved and much prolonged ; the 

 third, situated between the anal angle and the apex, is comma-shaped, and almost 

 joins the third costal spot ; at the apex of the wing is a round black spot (rather oval 

 in the female) : cilia varied silvery white and pale tawny. Posterior wings clear gray ; 

 cilia grayish fulvous. In the female, the base of the anterior wings on each side of 

 the basal streak is nearly all white. 



Not a common species, but probably much overlooked, being confounded with 

 pomifoliella. I have several specimens from Scotland, taken last summer by Mr. 

 Jobson. 



Zeller says of it, " This appears with us the earliest of the Lithocolletes ; I have 

 even taken it on the 4th of April. Its period of flight is April, May, beginning of 

 June, then in July and August. It frequents alder woods. I found it near Glogau, 

 Frankfort and Berlin, both in the perfect and larva states, which latter I have not yet 

 observed nearer. Tischer bred it at Dresden ; Mann took it near Reichstadt and 

 Vienna, the first brood on hornbeam, the latter on beech, scarce." 



Hubner's figure, though very rough, has yet sufficient character about it to be 

 recognized as this species. Zeller's reasons for calling this Rajella in Oken's Isis, 

 were — that it was an alder feeder, that he knew no other alder feeder in the genus, 

 that the Linnean Rajella was an alder feeder, and therefore probably identical with 

 this species ; but on finding afterwards another alder feeder, which, moreover, resem- 

 bled much better the figure in De Geer referred to by Linneus, he immediately 

 changed the name ; and his reason for not calling it alnifoliella is, that Hubner's 

 figure differs slightly from it, which is certainly true ; but as Hubner's figure possesses 

 several of the characters of this species (which no other species possesses), I think my- 

 self justified in retaining Hubner's name.
