The literature on Epimetopus, as far as known to us, is as 

 follows: 



1851. Mulsant (Mem. de 1'Acad. d. Sciences de Lyon, I, p. 1) describes 

 Ceratoderus n. gen. for C. graniger n. sp. from the United States 

 of Columbia. 



1854. Lacordaire (Genera des Col., vol. I, p. 467), having seen no speci- 

 mens of the genus, reproduces Mulsant 's description but, being 

 aware of the fact that the name Ceratoderus is preoccupied by 

 Westwood, changes it to Epimetopus. 



1874. Leconte (Trans. Amer. Ent. Soc., vol. 5, p. 47) erects the genus 

 Sepidulum an anomalous member of the Hydrophilidae approach- 

 ing the genus Ochthebius, for costatumn. sp. from Texas, collected 

 by Belfrage. 



1874. Sharp (Entom. Mo. Mag., vol. 11, pp. 247-250) discusses the char- 

 acters of Leconte 's genus Sepidulum, finding that the tarsi are 

 5-jointed and refers to the structure of the abdomen. He places 

 the genus near Spercheus and describes Sepidulum trogoides 

 n. sp. from "South America or possibly Mexico" and Sepidulum 

 bullaium from India. 



1882. Sharp (Biol. Centr.-Arner. Coleopt., vol. 1, pt. 2, p. 88, pi. 3, fig. 

 3) places Sepidulum as a synonym of Lacordaire 's genus Epi-
