 A HISTORY OF CORNWALL CURCULIONIDAE (continued) CURCULIONIDAE (continued) Gymnetron bcccabungae, F. pascuorum, Gyll. antirrhini, Payk. Mecinus pyraster, Herbst circulatus, Marsh. Anthonomus ulmi, De G. rosinae, Des Gozis pedicularius, L. pomorum, L. Though widely spread in the county this beetle has not hitherto caused serious damage to the fruit crops. It appeared in some quantity in the St. Columb district in 1901, and brown undeveloped flower-buds of the apple, occasionally with the little white wrinkled dark horny-headed grub in- side, have been sent in from Penzance, Bodmin and Eos- castle, and have been observed in numbers at Callington and rubi, Herbst Nanophyes lythri, F.

This beetle occasionally lays its eggs in considerable numbers on the roots of turnips, swedes, cabbages and broc- coli, and the larvae on emerg- ing cause local growth and the formation of unilocular root galls rarely more than a half to three-quarters of an inch in diameter. A badly- infested swede from Bodmin carried no less than sixty- three, together with a few warty excrescences on the ' bulb.' The root crop is evidently not much affected by the presence of these galls, but young broccoli in the west of the county are occasionally ruined Ceuthorrhynchus verrucatus, Gyll.

Old piles on the shore, South Down (Keys) ; Falmoulh ; in drift wood, Trefuiis SCOLYTIDAE Scolytus destructor, Ol. This beetle often destroys the bark of felled elm in dif- ferent parts of the county, and a fine series of old elms in Tregolls Road, Truro, were cut down in the winter of 19056 on account of the ravages committed for some years back by the repeated mining operations of this beetle and its larvae just under the bark rugulosus, Ratz. This beetle appeared in considerable numbers in 1901 in some Lord Grosvenor apple trees near Callington that were badly cankered. Lately the beetle has been rather com- mon about Saltash. As in the case of S. destructor, the female tunnels vertically be- tween sapwood and bark, laying her eggs at short in- tervals, and the larvae when hatched continue burrowing and feeding at right angles to the parent gallery till they reach maturity Hylastes ater, Payk.
