Indian forest insects of economic importance Coleoptera . with scales medianly ; apical declivity less strongly anil less densely punctate thandorsal surface of elytra, and has on each side a mar-in. il sub-cylindriral apophysis ol>li<|in-lvtruncate on top. Length, 9 mm. to 15^ mm. I found this beetle in April boring into the wood and large branehes of khair (Acacia catechu) trees felled in the Jaula s£l Life History. forests in Kumaun the preceding cold weather. Tin- beetles were egg-laying. For this purpose they tunnel down into the wood about Jin. to k in., and then eat out a tunnel at rightangles both to right and left of the entrance-tunnel. Small ridges and 150 FAMILY BOSTRYCHIDAE unevennesses are left in this long tunnel, which is the egg-tunnel, and iscarried round the stem parallel to the outer surface. In this tunnel a pair of beetles were usual-ly found, apparentlythe $ and 2. Thereis often a depressionin the floor of theegg-tunnel just atits juncture withthe entrance-tunnel,which may be thepairing egg - tunnels. FIG. 96.
