new Species of Histerida?. 49 



dense punctulatum ; fronte lata, utrinque striata ; autennis pedi- 

 busque rufo-brunneis ; tibiis anticis 8-denticulatis. 

 L. 2| mill. 



Subcylindrical, but not parallel laterally, the widest part 

 being behind the humeral angle, black and shining, legs and 

 antenna? reddish brown, surface above is wholly, evenly, and 

 somewhat closely punctulate; the head, forehead is widely 

 transverse and parallel at the sides, with a well-marked lateral 

 marginal stria and triangularly prominent before the eyes; 

 the thorax, marginal stria complete ; the prosternum, ante- 

 rior lobe wide and narrowly marginate in front, surface with 

 rather large and shallow punctures not closely set, and there 

 are indications of two short striae at the base of the keel ; 

 the meso- and metasterna have no visible suture, and laterally 

 the punctuation is similar to that of the prosternum but more 

 scattered, and in the median area the points are fine and less 

 close, the mesosternum is marginate anteriorly and the pro- 

 jection somewhat obtuse ; the anterior tibiae have two denticu- 

 lations close together near the tarsi and six at regular intervals 

 behind them. 



The broad transverse forehead with its well-marked lateral 

 striae are notable characters in this species. 



Hah. Jalapa, Mexico. 



Teretrius marginatus, sp. n. 



Cylindricus, parallelus, rufo-brunneus, nitidus, undique parce punc- 

 tulatus ; antennis pedibusque concoloribus ; elytris stria basali 

 brevi obliqua ; tibiis anticis 5-6-denticulatis. 



L. 1| mill. 



Cylindrical, parallel on the sides, reddish brown, shining- 

 above, sparingly punctulate; the elytra with a short basal 

 oblique stria at about one-third of the elytral width from the 

 humeral angle ; this stria is similar to that of T. obliquulus, 

 Horn. The sterna are very finely and sparingly punctulate, 

 the prosternal strise are wide apart and at their bases are 

 close to the coxae, the striae are fine and widen out gradually 

 but very slightly from the base to the suture but do not join 

 at either end, the anterior lobe has a conspicuous marginal 

 stria which is continued posteriorly along the sides to the 

 coxae. 



The chief specific characters of this species, as in many 

 others in Teretrius and Teretriosoma , exist in the sterna. 



Hab. Nepal, India.
