After some critical remarks on the species, he says, — 



" According to Frolich this Tortrix flies on flowers in May and June, but my ex- 

 perience is entirely contrary to this statement. I might assert that this Tortrix does 

 not frequent flowers at all : it generally flies but little, and therefore is so seldom met 

 with. Near Berlin I once caught several specimens on the 9th of May, towards even- 

 ing, on the trunks of moderately thick aspens, and two of them were paired. After- 

 wards, in Frankfort on the Oder, on the 17th of March, from branches of aspen, which 

 also contained, larvae of Saperda populnea, and which I had placed in water in a win- 

 dow exposed to the sun, I reared a fine female, which sat upon the young aspen-leaves. 

 I then thought the larva had lived in the buds, and sought therein accordingly, but 

 found only one larva, which I carefully described, but from which I only bred Penthina 

 dealbana. At Glogau, on the 11th of May, 1851, on a young aspen, T caught a male 

 which thus early was somewhat injured, going to prove that the time of flight could 

 not extend far into the second half of the month, that consequently the indication of 

 1 June ' has not much probability, and, as all the allied species appear only once a 

 year, there is no reason to think there is a second brood of this. In the year 1852 I 

 procured, from two Coleopterists of this place, branches of aspen, in which were Sa- 

 perda larvae. On examination of the knots on the branches I noticed, in a defective 

 part, an empty pupa-case projecting from the wood, and it immediately occurred to 

 me that it might very likely belong to corollana. I therefore next examined other 

 injured branches, and when I saw some larva-excrement hanging out of one I became 

 certain that the larva of corollana lived in the wood of aspens. Only one of these 

 branches furnished me with a moth, a male, which came out in the morning of the 

 11th of May. The branch was, underneath a twig, somewhat knotty and decayed. 

 I had cut into it, in April, just down to the cavity wherein the pupa lay, in a web of 

 powdered wood, with the head upwards, very lively, and still quite yellow. I fastened 

 the pieces of the branch together again, and looked at it from time to time, and thus 

 observed how the pupa became coloured. As it had lain with its head within the wood, 

 I feared that, as in consequence of my cutting into the wood it had fallen out, I had 

 replaced it in an unfavorable position, but this fortunately did not appear to have 

 been the case. I saw, on the 11th of May, the pupa had worked itself out through 

 a decayed part hitherto unobserved by me, from which it was almost entirely 

 suspended ; it became thus all but exposed; still it could make use of the spines 

 of the abdomen, by means of which it had doubtless burst through the place 

 of its exit, which had been prepared beforehand by the larva. At first I could 

 not find the moth, and on shaking the box it did not fly off. At last I saw it 

 sitting on a small bit of the wood, with its wings in a convex, roof-shaped position. 

 In consequence of my having disturbed it, in my endeavours to put it into a small 

 glass, it became very lively in the sunshine. A second fine example of corollana, 

 which came out with the Saperda, I afterwards received from Herr Capt. Quedenfeld, 

 one of the above-mentioned Coleopterists. 



" It appears to me, from the foregoing details, that this moth is not so scarce as 

 hitherto supposed, and that it may be obtained by breeding. For this purpose both old 

 and young lower branches of aspens should be examined in the winter and spring, at- 

 tention being directed to those having the knots of Saperda larva, as both these
