teeth (t/ t.") on the Dascillus tongue. The sclerites have 
suffered great fusion in Geotrupes, their boundaries being 
indistinguishable.

The maxillulae are undoubtedly represented by the lobes 
bearing the lateral groups of spines (mxl.), and corresponding

however, that they are fairly well developed in the larva of
