The destructive animal which we are about to treat of has been long 

 known, as much, probably, from the great numbers in which it generally 

 occurs as on account of the injury it occasions, and we find it mentioned 

 in the works of the founder of the system. Since his time so much 

 has been written about it that it becomes a matter of some difficulty 

 to keep within the bounds of a periodical, and at the same time not to 

 omit notice of matters deserving to be recorded. 



I will begin by my own observations. On the 10th of July, 1845, 

 I received from Dr. M. C. Verloren six larvae of Lophyrus Pini, which 

 he had found near Zeist or Driebergen. These larvae, fed, whilst in 

 my possession, on the leaves of the common pine (Pinus sylvestris) . 

 They pupised among the withered leaves, at the end of July. The 

 first appearance of a perfect insect from the cocoon was on the 5th of 

 August; this was a female; the others remained over the winter, and 

 did not appear until the month of June in the following year. I have 

 since had the larvae more than once, and have succeeded in rearing 

 them, some males among the number, but I have kept no record of 

 the dates. The following appears from my notes of the metamorphoses 

 of the larvae. The larva attains a length of one Paris inch and three lines, 

 or 35 mm. The whole body is yellowish green. Head ochre-brown, 

 with darker mandibles, and two round black spots, in which are the 

 eyes. Obliquely below these are the little feelers, which are also 



* To these may be added, J. O. Westwood in ' Gardener's Chronicle ' for 1852.
