 The head is smooth with depressions in front of the eyes on 

 each side. The thorax is finely punctured near the sides, and 

 smooth in the middle, with a rather deep longitudinal impression 

 on each side of the base, and the medial line distinctly marked. 

 The elytra are striated with a row of deep punctures in a 

 lateral channel, and two slightly marked depressions in the second 

 stria on each side of the suture, the one a little above the other, on 

 the posterior half of the elytra. The under surface is black and 

 polished. 



This species seems to be found in all parts of Australia. I 

 have named it from its resemblance and proximity to the genus 

 Lic'nms.
