308 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
Following my usual custom, I choose out for more detailed 
notice such of the pests as were complained about. 
Gos TIGRINA (De Geer). 
This is an interesting case, which exemplifies the helpfulness 
of the entomologist in detecting swindles. 
Mr David Glen, forester to Lord Sefton, advised a friend, who 
had bought some timber as English-grown oak, that his purchase 
consisted really of “‘American” oak. One of the logs on being 
split showed much insect injury, the wood being traversed by 
large tunnels which rendered part of it useless. A specimen of 
the timber, with a large beetle present in it, was sent to me from 
Croxteth by Mr Glen. The beetle, which was alive in the log, 
and which as grub had bored the tunnels, was a large, handsome 
Longicorn. It proved on examination to be Goés tigrina, a North 
American species. As this beetle is not found in our country, it 
was clear that the buyer of the timber had not got the English 
oak he bargained for. 
PIssODES NOTATUS, 
the Small Brown Pine Weevil, is injurious both as imago and 
grub, but chiefly as the latter. The mature weevil in its feeding 
pierces the bark with its proboscis, so that a badly-attacked 
young pine looks as if a person had taken a needle and made a 
number of little punctures with it on stem and branches. The 
proboscis pierces through to the cambium of the stem, and into 
the outermost part of the youngest wood. In healthy pines little 
bead-like drops of resin issue from the punctures. The grub 
tunnels in the bark, and between the bark and the wood, and 
where the bark is thin the outermost part of the youngest wood 
may be also gnawed away. 
The favourite breeding-places are young pines from three or 
four to eight years of age, but trees in the pole stage are also 
frequented. Scots fir, Austrian pine, Corsican pine, and Wey- 
mouth pine are all used as host-plants. In exceptional cases 
spruce and larch may be attacked. 
The female lays her eggs in holes in the bark, several, it may 
be, together ; and as the grubs when they hatch bore in different 
directions, the tunnels may have a star-like pattern. A trail of 
brown bore-dust remains behind to map out the path of the 
larva, The full-fed larva gnaws out a hole in the splint-wood, 
and in this hollowed-out bed, protected by a cover of sawdust
