Of all couiferoii.s plants, perhaps none are more subject to insect attack than the White Pine.Upward of a hundred species are reported to affect this tree, and a careful compilation of allknown species would probably add many more to tliis list. The more important are found in theorder Coleoptcra, and of these the cylindrical bark-beetles of the family Scolytida hold the highestrank. Mo

These are the exit holes of beetlesthat have in their larval stage mined and developed under the bark.Holes are also made by the mature insects, probably chiefly males, inthe latter days of a season after midsummer, evidently for no otherpurpose than for food. A piece of twig, showing exit holes in the barkand the galleries of the insects beneath it, is reproduced in figure 2. The insect which causes this injury is a member of the Scolytidge, afamily of cylindrical bark-and-wood-boring beetles. The adult or beetleis sh

When the larva? live under bark they become greatly flattened. Those that feed in wood or grain are mostly cylindrical. Those that live on the surface of leaves, lil<e the Potato-beetle, are often oval or irregular in shape. The number of species of beetles which have been described is probably over one hundred thousand. Of these, over ten thousand inhabit America north of Mexico. Fortunately. Fig. 65 a. — Larva of Lach

Figs. 6-1L) The western pine beetle is a rather stout, brownish, cylindrical bark- beetle, from 3 to 5 mm. in length, with head broad and grooved, pronotum punctured and but slightly narrowed toward the head, and elytra with fine rugosities, but entirely without long hairs. (See fig. 6.) It attacks healthy, injured, and felled western yellow pine and sugar pine, and is destructive to living timber in the moun- tains of Californ
