THE GENUS PISSODES AND ITS IMPORTANCE IN FORESTRY, 35 
the additional admission of our third proposition, viz., the pos- 
sibility of three broods in the space of two years. Most believers 
in a one-year generation would, I think, be prepared to assent to 
this possibility. The females, it would appear, take a long time 
over their egg-laying. One can imagine that in very favourable 
weather conditions the first eggs might be laid early enough to 
allow of all the stages being passed through, so that beetles 
might emerge in time for copulation and egg-laying in the same 
season. The larve from the eggs of these early beetles would, of 
course, be overtaken by the winter, and when they did arrive at 
the beetle stage in the following year, the next generation from 
their eggs would emerge to hibernate as mature beetles. 
Means of Prevention and Extermination.—It is pleasant to 
know that, troublesome as our pest often is, vigorous and timely 
measures are certain to prevail against it. The great principle is 
the rooting out of all weak trees. 
As guides denoting attack may be mentioned the bead-like 
drops of resin that issue from the wounded bark, the drooping of 
the plants, and a reddening of the needles, Infested plants 
should, before the escape of the weevils, be uprooted and burned. 
In districts on the Continent which have at different times 
suffered from fire, it was noticed that notatus was attracted to 
the singed and weakened pines, hence the recommendation that, 
in the case of an onset, here and there in the nursery or planta- 
tion plants should be artificially weakened. These weakened 
plants, taken possession of by the beetles for breeding purposes, 
will later on be dug out and destroyed. Some help is given from 
parasites. More than once J have found noéatus larve attacked 
by ichneumons. 
Pissodes pini, the Larger Brown Pine Weevil. 
Description.—This pest measures 2 inch, and is red-brown to 
brown-black in colour, with sparse yellow scales on both upper 
and lower surfaces. The punctured thorax has a fine raised 
middle line. Its posterior corners are right-angled, and the hind 
edges show scarcely any sinuosity. In front of the elytra two 
yellow spots on each side. Below the middle of the elytra a 
small continuous transverse band, composed of yellow scales 
compacted together. There are rows of long deep pits down the 
wing-covers.
