The European Lemoniid?e are included as a connecting link. The narrow cross bars indicate points at which cubitus became 4-branched on the fore wings ; the broad shaded bars, points at which the larva-tubercles became warts.

V. Riley published a paper on the food-habits of the long-horn beetles or wood-borers. Since then considerable has been added to our knowledge on the food-habits of this family of beetles. It has therefore been deemed advisable to republish Dr. Riley's paper with such additions which have been made. For personal credit the reader is referred to Dr. Riley's paper and Packard's Fifth Report U. S. Ento-mological Commission. We are also indebted to Mr. L. H. Joutel for many notes incorporated in the present paper and which have not been published elsewhere. Ergates spiculatus Lee. — This western species is recorded as living in the roots of coniferous trees, especially pine. Mallodon dasystomus Say. — Bores in the wood of oak, hack-berry {Celtis) and pecan hickory, and undoubtedly other species of hickory. Mallodon melanopus Lin/i. — Lives in box elder (^Negiuido aceroides), oak and hackberry (^Celtis').
