Another species, Cryphalusbinodiilu8,!\X- tacks the aspen, utterly destroying the tree, beginning with the branches and working downwards; and Scoli/- tus destructor, also com- mon in England, the elm, destroying not only the inner bark, but burrowing half an inch deep into the solid wood. The numerous species of the genus Platijpus, and its allies, differ in habits in some particu- lars from the rest of the family; at least, the English species, P. c>/- Unclrus, is found to liurrow in the solid wood of oaks and beeches. The other families of the Rhynchophora are the BrenthidjE, , and Bru- CiilD-E. The first-mentioned are very elongate, narrow Beetles, with rostrum long and filiform in the females, and shorter and broader in the males, the latter sex being pi-ovided also with strong mandibles. Like the Curculionidse, they have no labrum, or upper lip. They are bork-insects, very numerous and varied in the tropics, and displaying great eccentricities of form, but extremely rare in north temperate. LAIIIXI'S M.\ .-Losr*.
