They are frequently highly coloured, but the majority are not pleasing >bjects, and many species cover themselves with a coat of the excreted fragments of devoured leaves, which gives them a filthy appearance. The larvae of many small species are little flattened worms mining in the leaves, that is they feed upon the inner substance of the leaf, leaving the upper and lower surfaces untouched, and making disfiguring blotches, such as are also caused by larvae belonging to other orders. The beetles are frequently very handsome ; resplendent with gay colours and bright metalic lustres, or ornamented with quaint and striking markings. About five hundred species are recorded from the United States and Canada, and in both countries con- siderable damage has been inflicted by different species. Descriptions of several species and accounts of their operations have already been given in previous Reports, but as they are scattered through the different numbers, and perhaps inaccessible to some who may receive this, a brief review of them (as they are reached) may not be superfluous. The genus Donacia, with which the family commences, approaches in some respects to the Cerambycidae, or "long-horned" beetles, and serves as a partial link between that family and the Chrysomelidae. The beetles of this genus differ from those of most other genera in having longer and more cylindrical bodies and longer antennae. The larvae are said to live in the stems of water-plants, and to make a leathery cocoon in the earth before transforming. I have often found empty cocoons of such nature attached to roots of aq
