This species is larger and less parallel tlian T. puhx, Fairm,, 

 and the pygidium is more distinctly convex, but the sterna 

 are constructed very similarly in both species.

Tiretrius di'stinctus, sp. n. 



Cylindricus, piceus, nitidus ; prosterno conspicue marginato, striis 

 obscuris, brevibus ; mesosterno tenuiter marginato ; abdomine 

 segraento 5" in medio prominulo. 



L. 1| mill. 



Cylindrical, piceous, shining ; the head convex, lateral 

 stria rather strong, surface with that of thorax rather coarsely 

 but not closely punctured ; the elytra are rather less strongly 

 punctate ; the thorax is reddish at the anterior angles and 

 the marginal stria complete and well-marked ; the pygidia 

 are equally but not densely punctured ; the prosternum is 

 markedly marginate, truncate anteriorly, oblique laterally, 

 surface evenly and clearly punctate, striae short and obscure ; 

 the mesosternum rather sharply acuminate, with a fine mar- 

 ginal stria, surface and also that of the raetasternum punctate 

 like that of the prosternum ; the abdomen, the segment next 

 to the pygidium has an overlapping semicircular projection 

 in the middle of its posterior edge; the antennas have long 

 flavous hairs on the scape ; the legs, anterior tibise 5-dentate. 



I only know the male of this species, so that the projection 

 in the abdominal segment may be a masculine character.
