acetabulis anticis apertis. Mesosternum transversum, apice 
concayum. 
Type, Xenaltica Mur rayi. 
Although agreeing with Ewutrea in possessing a double 
spine at the apex of the hinder tibiee, the present genus 
differs so completely in all other characters, that it 1s not 
necessary to point them out. In facies it closely resembles 
LEdionychis and allied genera, but is separated from them 
not only by the double spine of the hinder tibiae, but also 
by each of the four anterior tibiz being armed with a 
small spine.
