streak from the base beyond the middle, and with seven oblique, marginal, opposite 

 (the last excepted) silvery spots, and a subocellated black spot at the apex." 



The figures in Wood and Duponchel have both the same fault, — that of the basal 

 streak not being long enough.

Expansion of the wings A\ — 4^ lines. Head white, with a few brown hairs. Fore- 

 head white. Palpi white. Antennae white, annulated with fuscous. Thorax pale 

 tawny, the sides silvery white. Abdomen fuscous, with the extremity fulvous. Legs 

 whitish. Tarsi white, annulated with fuscous. Anterior wings shining, pale tawny, 

 with a silvery white basal streak reaching over a third of the wing : on the costa are 

 four silvery white spots, and on the inner margin three : the first costal spot is narrow, 

 and points towards the anal angle ; it is nearly straight, and terminates a little beyond 

 the basal streak ; it is not bordered with brown on either side, and its inner margin is 

 continued on the costa, half-way to the base of the wing : the second, third and fourth 

 costal spots are nearly comma-shaped, and margined internally with brown : the first 

 inner marginal spot is narrow, slightly curved, and terminates just beyond the first 

 costal spot, like which it is not margined with brown on either side ; the inner margin 

 to the base of this spot is generally pale silvery ; the second inner marginal spot is 

 nearly opposite the second costal spot ; the third is between the anal angle and the 

 apex ; both the second and third are margined internally with brown ; at the apex is 

 a long black spot : cilia tawny before the third and between the third and fourth 

 costal spots : just beyond the fourth spot is a dark mark in the cilia (which Zeller has 

 apparently, if this be really his species, magnified into a hook) ; the rest of the cilia is 

 pale, with a black arch round the apex, and continued to the anal angle. Posterior 

 wings clear gray ; cilia grayish fulvous. 



This species is very apt to be confounded with pomonella, but it differs by the first 

 pair of spots not being margined with brown, by the inner margin of the first costal 

 spot being continued towards the base, and by the tarsi being spotted instead of white. 

 I have a specimen of this insect which I took last year (probably on Penge palings, in 

 May, in company with pomonella) ; and it is in other collections mixed with pomo- 

 nella. 



Zeller says of it, " A discovery of Mann's ; flies at Tivoli, near Vienna, in May, 

 July and August, in company with abrasella, &c, on oaks. Herrich Schaffer found 

 this also near Ratisbon."
