HoMOTROPUS, gen. nov. 



Characters of Schizoc/nathus, but witb tbe clypeus con- 

 cave, deflexed and entirely rounded on tbe tbree free sides. 

 Antennal club composed of tbree very long lamella. 

 Labruni very sbort and transverse, witb a small but pro- 

 minent projection in tbe middle. INIentum narrowed in 

 front of tbe insertion of the palpi and emarginate in 

 middle of the anterior margin. Tarsi short and stout. 

 Thorax with sides and base margined. 



The principal character here is the emargination of the 

 margin of the mentum. In this respect there is an 

 approach ioAmhly terns, but that has slender tarsi, &c. 

 The elytra do not appear to have any membranous border; 

 it shoidd, therefore, be placed at the commencement of the 

 AdoretincB, 2iC.c,0Ydi\ng to Lacordaire's arrangement; but, 

 as in all other respects, in tbe general form, in the form 

 of the palpi, it agrees better with tbe Brachystei'yiince, I 

 prefer placing it at the end of that family. 



Amblocliilus, Blanch., is placed with doubt by Lacor- 

 daire at the end of tbe Brachysternina, tbe difficulties 

 being that Blanchard says nothing about the labrum, and 

 states that tbe antennee are 9-jointed. The labrum is 

 transverse, with a small mesial tooth-like projection. 

 Tbe antennae appear to me to have only 9 joints ; the 

 7th joint is slightly indicated, but is not, I think.
