XL — On new Species of Histcridse atid Notices of others. 

 By a. Lewis, F.L.S. 



This is the thirty- seventh paper on the Histeridae ; the hist 

 was publislied in July 1910. 



Linue (in 1735)/Paykull (1811), Marseul (1853), and 

 other writers have noticed varieties of many species, but 

 they abstained from giving them varietal names. It is 

 different now, and I think that if the present plan of pro- 

 cedure is continued systematists will year by year be more 

 and more discredited. Last year four names were added 

 to those of Hister macidatus, L., bringing the number up to 

 nineteen. The colour- varieties of H. maculatus are very 

 numerous, and names founded on them might easily be 

 brought up to thirty ; but would this be useful for a study 

 of the species ? The volume of the Catalogue would be 

 enlarged, but would the enlargement be serviceable, and 

 should the limit be 30? Saprinus varians, Sch., has but 

 one name at present, but, as its name implies, it is very 

 variable ; is it desirable to give it six or eight more names ? 

 And this question may be asked of a large number of 

 species. Gnathoncus rotundatus, Kug., has twenty names, 

 and Saprinus nitidulus, F., sixteen. 



In a time that we may anticipate but shall not see, 100,000 

 more Coleoptera will probably be described, and these at a 

 moderate computation will acquire 150,000 to 180,000 names.
