NOTES ON COLLECTING. 218 



ing of one worn female, one worn male, and, at 4 p.m. (June 13th), a 

 small female drying its wings at the root of a pine. This had 

 apparently found emergence (through grass or gorse roots) somewhat 

 difficult, and, though the wings were all right, the body, thorax, 

 and head, were all partially denuded of scales. It seems extremely early 

 for rubbed and worn specimens. Other interesting finds were whcit ap- 

 peared to be a larva of Malacosoma castrensis, a freshly-emerged female of 

 Panob's piniperda, and a three-quarter grown larva of the same species, 

 illustrating the vagaries of the season (as some fullfed larvae were 

 taken here yesterday). I should much like to try the experiment of 

 introducing H. pinaHtri into excellent pine-woods on the north side of 

 Norwich, far finer than where the species now occurs, and where it seems 

 to be quite out of place, pine-woods by no means predominating 

 there. If such an experiment were to succeed, it would still further 

 support the evidence that it is not indigenous to Britain, and that 

 it has either flown over and established itself, or has been 

 introduced by human agency in the Aldeburgh district. A second 

 visit to Aldeburgh, on June 20th, resulted in my taking four more 

 tl. pinastri, whilst three others were taken by another clergyman in 

 the previous week. Three were well marked, one male especially so, 

 with many extra dark marks, one male hopelessly worn. I ruined 

 one female in the fruitless attempt at " sembling," and the worn male 

 would not act. I spent many hours in searching all the pines in the 

 most favoured plantations, morning, afternoon, and before dusk, at 

 which latter time I got the two freshly-emerged specimens, on trees 

 which were barren when searched earlier in the day, but there were 

 evidently very few others about, as I saw none on the wing. I, more- 

 over, tried honeysuckle after dark without avail. I also failed to find 

 even the empty pupa-cases at the favoured trees, though I dug most 

 carefully all round the roots for about a foot. Doubtless they had 

 pupated farther afield, and had crawled back to the tree for the 

 drying process. On this visit too, I amply confirmed the presence 

 of Malacosoma castrensis at Aldeburgh. I went particularly to the 

 sandhills first to find this, and it was, indeed, pleasant in the cool 

 of the evening to stroll leisurely about and pick up a dozen 

 the first evening. Some were feeding on the narrow-leaved plantain, 

 but most were lying stretched out at full length on grass-stems. The 

 next day I searched again, but only found two, in the same place, 

 lower on the herbage. In the evening, at 7 p.m., I continued the 

 hunt, and at length came across their head-quarters, vis., over the 

 sandy lane at Thorpe, near Aldringham, and right on the salt-marsh. 

 Here they were in any quantity, some half-grown in nests, and many 

 more large and full-grown, spotted about on the top of grass- and reed- 

 stems all over the place, and most conspicuous even at a distance of 

 twenty or thirty yards. I was very pleased with my find. — (Rev.) A.

Plan of trapping Cerukid and other larv^. — A very successful 

 plan for trapping the larvae of the •' kittens," and other species, that I 

 have practised, is to pull off large pieces of loose bark from old trees and 

 nail them closely to those on which I knew larvae of Cemrafurcula, etc., 

 to be feeding. I place these on the north and east sides, chiefly about 

 thirty inches from the ground. In some cases, where I have also tried 

 the damp side, I have found nothing but woodlice, earwigs, spiders, &c.
