new Species 0/ Histeridae. 77 



Trypeticus crassus, Scli., 1892. 



Tri/peticus bifoveolatus, Lew., 1893. 



Schmidt recorded that the male of this species was in my 

 collection and came from Perak. The specimen referred to 

 is in the British Museum and belonged to the late Mr. Fry's 

 collection. 1 think now that the deep fovesein the pygidium 

 oi bifoveolatus is not a specific character, as I have seen five 

 examples without them, and my name therefore must fall 

 into the synonymy. 



Teretrius pradator, sp. n. 



Cyliudricns, niger, nitidus, sat dense piinctatus ; prosterno puncfato, 

 striis parallelis ; mesosterno sparse pmictato ; propj-gidio pygidio- 

 que modice dense punctatis ; pedibus brunneo-ferrugineis ; tibiis 

 anticis intus ciliatis. 



L. 3i mill. 



Cylindrical, black and shining, evenly and somewhat 

 densely punctured above ; the forehead convex ; the thorax, 

 lateral stria sinuous before the base, continuing, but finer, 

 behind the head ; the pygidium is convex, surface micro- 

 scopically strigose and evenly punctured, punctures not very 

 close ; the prosternum rather closely punctured, punctures 

 rather large and shallow ; the mesosternum is markedly 

 marginate, and with the metasternum and first abdominal 

 segment (all similarly) sparsely and somewhat finely punc- 

 tured ; the anterior tibiae are 10-11-dentate, with a few 

 fiavous hairs at the tarsal end on the inner edge, intermediate 

 7-8-, posterior 4-5-spinose. 



This species is much less robust than pilhnanus, Mars., 

 but the surface punctuation is closely similar. Some 

 examples have on the first abdominal segment a lineal 

 arrangement of punctures which correspond to the striae that 

 I have noticed in cEstivus.

 and my own collection. 



Teretrius cestivus, Lew. Ann. & Mag. Nat. Hist. xv. p. 470 



(1885). 



In the Catalogue of 1905 I placed this name in error as a 

 synonym of T. punctulatiis , Fahr. The prosternal striae are 

 not, as I stated, divergent except at the anterior tips, and 

 there is a marked specific character in a lateral longitudinal 

 stria on the first abdominal segment.
