 1838, p. 79. 



Characters of Calochromus, but with a distinct (but 

 short) rostrum. 



Type, L. sanguineus, Linn. 



Genus 4. 



Antennae short, compact, dentate, compressed, of equal 

 width throughout, 3rd joint a trifle longer than broad, 

 4th to 10th joints transverse. Rostrum distinct, but short. 

 Thorax rather transverse, quadrangular, disk smooth,

Type, Lycus Lacordairei, Kirsch. 



Note. — I have determined this species from description, 

 but I have little doubt as to the identity. L. succiuctus, 

 Latr., should also belong to this group.
