Revision of the Species of L.EBI A of the United States. 



BY GEORGE H. HORN, M. D. 



In the second part of the volume xliii., and the first part of the 

 volume xliv., of the Bulletin de la Societe Imperiale des Naturalistes 

 de Moscou, Chaudoir has published a review of the species of Lebiidae 

 as restricted by him. This tribe contains in our fauna only those 

 species which have heretofore been known under the one generic 

 name Lebia. Chaudoir proposes to divide the tribe into two primary 

 portions, as follows : 



Lateral lobes of mentum with epilobes Lampriadje. 



Lateral lobes of mentum without epilobes Lebiidte verm. 



As no mention has ever been made by any author of the " epilobes 

 of mentum," I translate from Chaudoir's description. "The great 

 majority of Lebiidae have a mentum of which the lateral lobes are de- 

 void of that appendage which in the greater number of Carabidae 

 borders the inner margin of the lateral lobes, and which is separated 

 by a very distinct suture ; this appendage, which varies in dimension 

 and form, deserves to receive a name, and I propose that of epilobe for 

 the same reason that the side pieces of the sternum are called epis- 

 terua. Although this epilobe is wanting in many Lebiidae it also ex- 

 ists in a great number." 



The first group, Lampriadje, contains in our fauna the genus 



L.OXOPEZA, Chaudoir, 

 which includes all our large species with metallic green or blue elytra 

 and which may readily be known from all our other species by the 

 greater or less obliquity of the dilated joints of the anterior tarsus of 

 the male. The latter character is well defined in all the species. 



As thus defined Loxopeza contains the following species : 

 Fourth joint of hind tarsus deeply emarginate. 

 Head and thorax rufous. 



Elytra deeply striate; antennse pale grandis. 



Elytra finely striate; three basal joints only pale atriventris. 



Head black, thorax rufous. 



Elytra deeply striate; outer joints of antennse darker tricolor. 



Fourth joint of hind tarsus feebly emarginate. 



Head and thorax rufous; elytra deeply striate majnscula. 



Head black, thorax rufous; elytra finely striate atriceps.
