the brand just after the middle of the fore-border of the wing ; 

 this brand is long and linear, thinned away at either end, termi- 

 nating rather abruptly at the tip, and forming a very obtuse an- 

 gle on the hind-border whence springs the fourth vein ; the first 

 and second branch-veins are indistinct and near together at the 

 base, but widely apart at their tips; the latter is slightly waved; 

 the third is obsolete till its fork which it sends forth at one-third 

 of its length, and it has no second fork ; the fourth vein is nearly 

 straight. 



Length of the body 1-1| line ; of the wings 3 lines. 



1st var. The feelers are dull green ; the tips of the joints are 

 brown : the eyes are black : the mouth is pale green with a brown 

 tip : the legs are pale green with dark brown tips : the wing- 

 brands are pale green. While the pupa is young, its colour is 

 yellowish green with a green abdomen ; when it grows older it 

 has four rows of black spots along the abdomen, and its rudi- 

 mentary wings are pale yellow. 



This species feeds on Pinus sylvestris, the Scotch pine, from the 

 spring to the autumn. 



The species of this group diiFer much from each other in shape, 

 and as I have not yet noticed all the forms in which they appear, 

 I shall probably mention them again in a future part of these 

 descriptions. Some of the species are solitary, others herd to- 

 gether ; Aphis saligna, Pinicola, Laricis, and Rohoris, occur in 

 thick clusters during the autumn, and the three last species are 

 then attended by large swarms of Scatopse picea, among which 

 S. flavicollis is sometimes found : these flies feed on the honey- 

 dew, an appropriate occasion for their pairing which accordingly 

 occurs at this time of the year.

106. Clytus angulatus. Taken at Savanna le mer, early in 

 June. 



107. Eriphus terminalis. Common on the Hampstead Road 

 in June. 



108. Eriphus (?) humeralis. Very numerous in the same loca- 

 lity and season as the preceding. 



109. Ptychodes trilineatus. Some half-dozen specimens of this 

 handsome beetle were procured on the Hampstead Road and in 

 the Cotta Wood at Content during the last week in June.
