to September. As beetles, they destroy the young 
branches of Conifers by boring small holes in them, and 
sucking the sap (see Fig. 157). Resin is apt to flow 
out from the openings, and the branches die, and fall 
off. : 
Prevention. This is best insured by the removal and 
burning of the branches, &c., cut off in wood-cutting 
operations. The supply of food for the larve is thus 
stopped. The perfect insects may be caught by using, 
as traps, flat pieces of bark, laid on the ground under 
weights, and frequently examining them; from these the 
Fig. 157. PIssODES NOTATUS, showing Insect (natural size) and 
Ravages to Trunk committed by it. The bark has been 
removed from the middle of the trunk, to show the galleries. 
beetles can be picked off. Or cut branches may be placed 
in suitable localities, and the beetles attracted to them 
may be shaken off and killed. A few logs should be 
left for a time, to induce the females to lay their eggs 
thereon; but they should be burned while the larve 
are still in them. Young Conifers should not be planted 
on the site of an old plantation, where numerous stumps 
serye as breeding-places for the beetles. Hand-picking 
is of use where the trees to be protected are few and 
small. 
PINGUICULA (a diminutive from pinguis, fat; re- 
ferring to the greasy texture of the plants). Butter- 
wort. ORD. lentibulariee. A genus of greenhouse or 
hardy, terrestrial herbs, broadly dispersed (in boggy 
places) over the extra-tropical regions of the Northern

hemisphere, a few being found in the Andes of America, 
extending as far as the Antarctic regions. Upwards 
of thirty species have been described, but probably not 
more than twenty are really distinct. Flowers terminal; 
calyx four or five-parted or bilabiate ; corolla purple, 
violet, or yellow, bilabiate, the lobes all spreading, entire 
or emarginate; scape erect, one-flowered, leafless, ebrac- 
teate. Leaves radical, rosulate, entire, often greasy to 
the touch. The hardy species thrive in a marshy, boggy 
soil, and are propagated by seeds, by leaf cuttings, or 
by division. The greenhouse species thrive in well- 
drained pots of peat and sphagnum or in fibrous peat 
and pieces of broken pots, and may be increased by 
the same means. The under-mentioned species are the 
best for gardening purposes. They are all perennials.
