XV. — On new Species o/ Histeridse and Notices of others. 

 By G.' Lewis, F.L.S. 



This is the thirty-fourth paper on the Histeridae in this 

 Magazine, and in these papers and in those published by me 

 elsewhere there are over 700 species described and about 55 

 genera established. Marseul described about 700 species and 

 founded 35 genera, so that his work and mine are nearly 

 equal as regards the number of species noticed ; but Marseul's 

 work is of more value, owing to the large number of fio-ures 

 given in his monograph. Marseul began his monograph 

 fifty-five years ago, and it is nineteen years since his last 

 paper was published ; in describing his species he generally 

 drew outlines of them, even when the drawings were not 

 published. 



There are several new species of Tribalus noticed in the 

 present paper, the number now described being over 30, and 

 there are perhaps as many more nondescripts in collections, jto 

 that ultimately the genus is likely to prove to be a large one. 

 At the date of the Munich Catalogue only 9 species were 

 known; three species occur in the European area, and the others 

 are African or Asian. Formerly Dr. G. H. Horn included 

 two American species in Tribalus, but these are now referred 

 to Ccerosternus and Stictostix ; the single species of the first 

 genus has, as already recorded (Ann. & Mag. Nat. Hist. xvi. 

 p. 213, 1885), an antenna with a solid club, and the species
