'i'lie figure given by Schiiklte and Mcincrt exaggerates, I 

 think, tlie relative proportions of the telson, wiiich appears to 

 be too short for its breadth (vide text, p. 16, where tiie 

 proportions are given as 8 : 7). The exterior branch of tlie 

 uroi)od.«!, which is long and styliforni, is pigmented with black, 

 and this pigmentation is continued up along tiie sides of the 

 abdomen, though it fades away on the sides of tlie thorax. 



Dim. : Greatest length 17*5 tnillim., greatest breadth 11 ; 

 breadth of telson 3'5, length of telson 4*25.

XXXV. — On new Species o/ Histeridaj and Notices of others. 

 By G. Lewis, F.L.S. 



[Plato X.] 



This is the eighteenth paper of a series on the /lisieridie 

 published in this Magazine, and in these various memoirs I 

 have described about 3(50 new species, and in other publica- 

 tions, during the same period, I have noticed 150 more. In 

 and between the years 1884 and 1897 Herr J. Schmidt 

 described about 2.i0 sj^eeies, and after the year 1868, the date 

 of the Munich Catalogue, Mar.seul described about 185, 

 Mr. L. Casey 48, and other authors about 157 species. These 

 figures represent in all 1130 species, which, with those of the 

 Munich Catalogue, 1151, bring the present number of species 

 recognized up to 2281. I have a new Catalogue in ^LS. 

 which I ho| e to publisli shortly after a few points of .synonymy
