Book Description

Excerpt from North American Cerambycid Larvæ A Classification and the Biology of North American Cerambycid Larvæ The objects Of the bulletin, therefore, are to describe those species of cerambycid larvae which have been reared and to give some information on their food habits and biology which will serve as a basis for a more practical discussion of the injurious aspects and control; also to indicate the systematic relationships Of these larvae in the hope that these may be of assistance in the identification of the species in the larval stages and in the recognition of more exact relationships among the Imagines. Limited as this discussion is to part Of the North American fauna, the difficulty Of showing any broad relationships is recognized. Probably the better expression of such taxonomic positions, as shown by the larvae, will be found in groups Of related genera or species where sufficient series of larvae have been available. For this reason no attempt is made to Show any taxo nomic relationships in the keys, but to use artificial arrangements based on the more evident characters so as to allow the determination Of the genera and species by the most expedient means. In the text the discussion of the genera expresses the writer's ideas Of their relationships. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
