I. — On new Species o/'Histeiidae and Notices of others. 

 By G. Lewis, F.L.S. 



The present paper is the sixteenth of a series on the Histeridaj 

 published in this Magazine^ and contains descriptions of 

 twenty-eight new species, with notices of others which an 

 increasing knowledge of the family renders desirable. 



To show some important characters of certain Saprini I 

 give first an outline of the prosternal keels and tibiae of 

 Saprinus C7'uctatus, F. (fig. 1), S. maculatus, Rossi (fig. 2), 

 and S. 7iitidulus, Payk. (fig. 3), and for comparison figures 

 of the same parts of two species of Gnathoncus. Fig. 4 

 represents G. I'otundatiis, Kugel, fig. 5 G. nannetensis, Mars., 

 and of the first an outline of the mandible is also given. 

 Figs. 6 and 7 show the corresponding details in Hypocaccus 

 4,-stn'atus, Hoff"m., and rugifrons, Payk., respectively; and 

 fig. 8 exhibits the form of the keel, anterior tibiae, and man- 

 dible of Pachylopus niaritimus, Steph. The side views given 

 of the keels show that those of S. maculatus and cruciatus 

 continue anteriorly on the same plane as the base, and the 

 other large species, such as S. semipunctatus, F., rasselas, 

 Mars., splendidus, Payk., and viridanus, Lew., are formed
