Excerpt from The Labium and Submentum in Certain Mandibulate Insects During the last few years various papers and works have appeared which more or less touch on the homologies of the mouth-parts of Insects. In nearly all cases the submentum is included in the mouth-organs as part of the labium. Most authors state that it represents the united cardines of the second pair of maxillae, without giving any distinct reason for making the statement; others give reasons which are more or less unsatisfactory; but no one, so far as I am aware, has demonstrated that this view is correct. It is therefore to a great extent with a hope of calling attention to. This that I venture to publish some figures of mouth organs, which I think will be interesting, and which tend to show that all the parts of the maxillae can be accounted for in the labium without the submentum.
