246 [April, 



to be a variety of Buolicma. Dr. Wocke, in his list, sinks it as such, 

 and Prof. Zeller considers the colour of the specimens to vary to some 

 extent according to the species of pine upon which the larvae have 

 fed. I am, however, like our best English entomologists, strongly of 

 opinion that the species are distinct, and I look upon the longer and 

 more pointed fore-wings, as well as the brighter colour and more 

 defined silvery white markings of plnicolana, as good distinguishing 

 characters. Prof. Zeller tells me that he has separated the two forms 

 in his collection for future investigation, so I hope he may in time 

 see reason to agree with our opinion. 



Mr. N. Greening, of "Warrington, who has taken and bred plni- 

 colana freely, tells me that it differs from BuoUana in habits and time 

 of appearance. He says that when BuoUana is getting worn (about 

 the beginning of July) is the time yvhen pinicolana makes its appear- 

 ance, and that, while BuoUana is coming out, pinicolana is to be found 

 as a full-fed larva or pupa in the fir shoots. Also that when it has 

 made its appearance in the perfect state it is far more sluggish than 

 BuoUana, falling to the ground when the fir trees are struck and 

 hiding itself among the grass or heather ; while the latter species, 

 instead of falling, flies about the trees and settles on them again. 

 Moreover, he says that BuoUana flies of its own accord for three 

 hours — from three to six p.m. — on fine days, dashing round the trees, 

 while pmicolana merely flies for about an hour, later in the afternoon, 

 and then not in the same lively zig-zag manner, but tolerably straight 

 from tree to tree. This evidence as to the distinctness of the two 

 species seems to me of great value. 



Betinia pinivorana, Zell. — I reared this species rather freely from 

 larvae collected in Woolmer Forest some years ago. They seemed to 

 affect the young side shoots of Scotch fir rather than the central one. 

 Particulars may be found in Ent. Mo. Mag., v, pp. 178 — 9. 



Grerman specimens of this species seem to be paler than ours. 



Betinia resineUa, Linn. 



Betinia sylvestrana, Curt. — Apparently a rare species on the 

 continent. 



Betinia duplana, Hilbn.— Prof. Zeller tells me that this species 

 flies in April and the beginning of May. 



Betinia TiirioneUa, Linn. — Dr. Wocke refers Linnu's TurioneUa 

 (with doubt) to BuoUana, and substitutes Turionana, Iliibu., for this 

 species.
