inttimedialc longer and more robust than the anterior, but similar in other 



respects. 

 posterior like the intermediate, but rather longer; coxie considerably distant. 



This genus differs from Cori/hphns in both the shape and number of the joints 

 of the antennse, and also in many parts of its anatomy. All the species yet known 

 belong to the warmer regions of the earth ; with few exceptions they inhabit the 

 Western Hemisphere, and may be regarded as the antitypes of the Old World 

 Corj'lophi. In outward appearance they resemble the C'DccincUidte so closely that 

 some species have been described by more than one author as members of that 

 familj' ; but in all these cases the antennre and organs of the mouth are of the 

 most normal Corylophide character.
