Of our numerous species of this family, we know the development and earlier stages of only one species, viz, Fuller's rosebeetle (Aramigus Fulleri). A few other species have attracted attention by the injury caused by them as perfect insects. They are as follows: Epicoerus imbricatus, a very general feeder; Pachnoeus opalus and Artipus floridanus, both injurious to the orange tree. Of a few other species we know the food-plants: thus Neoptochus adspersus feeds on oak; Pachnoeus distans on oak and pine; Brachystylus acutus is only found on persimmon; Aphrastus toeniatus lives on pawpaw (but not exclusively); Eudiagogus pulcher and rosenschoeldi defoliate the coffee-weeds (Cassia occidentalis and other species of the same genus). Two very common species, Pandeleteius hilaris and Tanymecus confertus, appear to be polyphagous, without preference for any particular plant. Very recently the habits of another species, Anametis grisea Horn, were brought to our knowledge by Mr. George P. Peffer, of Pewaukee, Wis., who sent us specimens of the beetle accompanied by the following communication: "The larger curculio I send you is working around the roots of apple and pear trees, near the surface of the ground or around the union where grafts are set.
I found fifteen of the larvae on a small tree one and a half inches in diameter. The beetle seems to lay its eggs just where the bark commences to be soft, near or partly under the ground. The larvae eat the bark only, but they are so numerous as to girdle the tree entirely in a short time."--C. V. Riley.
