new Species of Histeridse. 159 



Oval, convex, black and shining, outer margins o£ the 

 elytra red, at the base the colour reaches the third stria and 

 gradually widens out to the apex ; the head is somewhat 

 irregularly, not densely punctured, forehead impressed, stria 

 interrupted anteriorly; the thorax, marginal stria complete 

 and crenulate and conspicuous behind the head, lateral stria 

 well-marked and arched behind the anterior angle and ceasing 

 behind the eye, and is shortened a little at the base, surface 

 irregularly punctured, points largest within the lateral margin ; 

 the elytra, dorsal stria3 1-5 complete, fifth feebly hamate 

 at its basal end, sutural apical and abbreviated by one- 

 third, outer humeral short and apical, inner wanting ; the 

 propygidium is evenly, not densely punctured; the pygidium 

 is nearly smooth, the punctuation being microscopical ; the 

 prosternum is bistriate, the striaa join at the base and are 

 nearly parallel along the keel and not therefore joining in 

 front ; the mesosternum, marginal striae complete, crenate, and 

 are shortened before the coxa?, the second stria is also arched 

 and crenate, but reaches the posterior coxse ; the legs are 

 reddish brown. 



The coloration of this species somewhat resembles that of 

 P. hcemorrhous, Mars. 



Bab. North America (Dane Co., Wis. 1899, and Eddy- 

 ville, Ja.j H. F. Wickham). 



Phelister carinistrius, sp. n. 



Ovalis, convexus. brunneus, nitidus ; fronte stria integra antice fere 

 recta ; pronoto basi utrinque obliqua distincte striata ; elytris 

 striis cariniformibus, omnibus integris, 5 cum suturali basi juncta ; 

 tibiis anticis 8-9-deuticulatis. 



L. 2-2| mill. 



Oval, convex, brown and shining; the head sparsely and 

 finely punctulate, not impressed, stria slightly carinate, com- 

 plete, and widely transverse anteriorly ; the thorax punctulate 

 like the head, with a few larger punctures laterally, opposite 

 the fourth stria is a basal, oblique, carinate stria ; the elytra, 

 humeral strise very fine and somewhat obscure, outer slightly 

 broken in the middle, inner shortened at both ends, dorsal all 

 complete and carinate, sutural and fifth join anteriorly, apical 

 border punctulate ; the propygidium finely and not closely 

 punctulate ; the pygidium almost smooth, points being very 

 fine; the prosternum, keel narrowed in front, strise joined 

 anteriorly and widening out to the base; the mesosternum, 

 strise marginal and transverse, both equally arched and 

 parallel to each other, and so continue down to the base of 

 the metastcrnum ; the anterior tibiae are 8-9-dcnticulate.
