new Species 0/ Histeridse. 403 



rostrum is oblong, truncate at the base, marg-ins narrowly 

 elevated, feebly punctulate on the surface, tlie anterior edge is 

 very feebly retlexed and feebly emarginate ; thorax striate at 

 the sides, very distinctly and somewhat closely punctured, 

 except in front of the scutellum, which has a very narrow 

 irregular space smooth, behind the neck there is a short and 

 "fine line; the elytra are finely punctured with similar density, 

 with a narrow margin at the bases and sutures smooth ; the 

 propygidium and pygidium are somewhat closely punctured, 

 the latter is convex on its upper surface ; prosternum feebly 

 punctured, and it widens out a little anteriorly, truncate at the 

 base, bistriate, stria? parallel ; the mesosternum is wider, also 

 feebly punctate, lateral stria straight and rather deep ; raeta- 

 sternum less visibly punctate, median line well marked ; legs 

 and antennge Havous, anterior and intermediate tibiae 5-den- 

 tate, posterior tibiae short and a little dilated.

(^ . Filiform, brown, shining, under surface, angles of the 

 thorax, and edges of the elytra testaceous ; head very similar 

 to the last species, but much narrower, with eyes less promi- 

 nent ; rostrum also similar ; thorax very finely punctate, 

 anterior angles lightly produced, stria at sides only ; elytra 

 with punctures almost obsolete, also the propygidium ; 

 pygidium convex on the upper surface, visibly punctulate ; 

 prosternum oblong, striate at the sides, truncate at botli ends ; 

 mesosternum half as broad again, equal to it in length, with 

 similar striae, both feebly punctate ; mesosternum smooth, 

 median line fine ; anterior and intermediate tibige 5-dentate, 

 posterior not dilated in the same degree as in 7\ obeliscus. 



This species differs from T. obeliscus in being smaller, fili- 

 form, with thorax very finely punctured and not rounded off 

 anteriorly, pygidium more finely punctured, and by the form of 

 the posterior tibiae. Both species are, however, allied, with 

 the eyes prominent and the head narrowed behind the eyes. 

 The frontal strige, transverse and straight between the eyes, 

 is also a remarkable character in each.
