Description. 
Larva . — Wliitish yellow, elongate, the segments of the body more or 
less of the same size decreasing gradually posteriorly. No enormously 
large segment follows the head as in the case of the buprestid larva. 
Head black. Length about 1” when full grown. See Plate IV, 
figs. 1, \a. 
Beetle . — Brown ; head and prothorax clothed with a greyish pubes- 
cence, the prothorax with four small brown spots in a transverse 
row across the middle — two dorsal and two lateral. Elytra subglabrous, 
testaceous brown, narrowly covered with grey pubescence at the base, 
marked with some small spots of ashy-grey pubescence which form three 
interrupted bands — one near the base, another just before the middle, 
the third midway between it and the apex ; the apex also narrowly 
bordered with ashy-grey. Body beneath covered with grey pubescence, 
a rather large posterior spot on each of the metathoracic episterna ashy- 
white. Antennte less than half the length of body ; third joint slightly 
longer than the first. Femora rather strongly thickened ; the hind pair 
extending a little past the apex of the elytra. First joint of hind tarsi 
twice as long as the second and third united. 
Length 12 — 18; breadth Sj — 5 millim. [^Descr. after Gahan).

Life History. 
The larva of this insect feeds entirely in the bast and outer sap wood 
of the Morn oak. I have not as yet taken it in the Ban. The grub 
grooves both bast and sap wood, eating out large irregular galleries in the 
long axis of the tree (Plate IV, fig. 3). Occasionally the gallery is quite 
straight, but it is more often irregular with winding edges ; the larva 
however, appears to confine itself to the layer of wood between the long 
straight medullary rays and more esj^ecially so in its young state. The 
larval gallery is always tightly packed with the wood refuse and excreta 
ejected by the larva and is about o" to 8" in length with an average 
breadth of ith inch. On becoming full grown the grub bores down 
into tbe sap wood at an angle for about to 1" and then eats out a 
pupal chamber parallel to the long axis of the tree (fig. 4). Both 
chamber and entrance gallery in the wood are kept quite free of wood 
dust and excreta. When mature the beetle crawls up the entrance
