MORDELLISTENA RHENOLEPIS, new species 

 FiGXiREs 16, c; 18, a 



This species is allied to ozarJcensis Ray (1936a, p. 125) and may be 

 separated from the latter member of the genus by the additional 

 ridge on the posterior tibiae, the completely flavocastaneous condition 

 of the head and pronotum, the more parallel form, and the longer, 

 hammerlike distal segment of the maxillary palpi. Among the Cen- 

 tral American forms rhenolepis is most closely allied to leata Cham- 

 pion (1891, p. 347) and may easily be separated by the unicolored 

 pronotum, the difference in the number of comblike ridges on the 

 posterior tibiae and tarsi, the different position of the basal cinereous 

 vitta on the elytra, and the greater length of the fourth antennal 

 segment.
