new Species o/" Histeridse. 149 



Oval, convex, black and shining; the head obscurely punc- 

 tulate, frontal stria semicircular ; the thorax, marginal stria 

 interrupted behind the head, outer lateral wanting, inner 

 complete, fine behind the head and rather irregularly im- 

 pressed laterally, behind the anterior angle there are a few 

 fine points ; the elytra, strise, inner humeral a little shortened 

 at the base, dorsal 1-3 complete, 4 and sutural equal and 

 nearly dimidiate, 5 very short and broken, apex slightly 

 transversely impressed ; the propygidium and pygidium are 

 evenly and rather closely punctured, the first has a distinct 

 but rather shallow fovea on either side ; the prosternum, 

 anterior lobe margined, but the stria is only close to the edge 

 at the apex ; the mesosternuin is slightly sinuous anteriorly 

 and the marginal stria is fine and complete ; the anterior tibige 

 are 5-denticulate. 



This species may be placed near H. conductus, Mars. 



Hah. Bahia {E. C. Reed). 



Ulster plant frons, sp. n. 



Ovatus, convexus, niger, nitidus ; fronts baud striata ; prouoto 

 bistriato, striis antice disjunctis ; elytris stria subhumerali 

 sinuata, integra, striis 1-4 iutegris, 5 suturalique valde abbre- 

 viatis ; propygidio pygidioque parum dense punctulatis. 



L. 5 mill. 



Oval, convex, black and shining ; the head without a 

 frontal stria, feebly punctulate and somewhat uneven, there 

 is a small fovea in the middle of the base, but it may not be 

 constant ; the thorax, marginal stria complete, outer lateral 

 hamate and ceasing behind the anterior angle, inner complete 

 except in being very slightly shortened at the base, scutellar 

 fovea linear ; elytra, stna3, subhumeral complete and widely 

 sinuous in the middle, 1-4 complete, 2 sinuous in the middle, 

 4 and 5 joined at the apex, 5 and sutural very short ; the 

 propygidium and the pygidium are evenly and rather closely 

 punctulate; the prosternum, keel finely punctulate; the 

 mesosternum emarginate, stria complete anteriorly but not 

 quite reaching the suture at the base; the anterior tibia3 5-6- 

 denticulate. 



The absence of a frontal stria is a marked distinction in 

 this species ; hitherto //. planiceps, Lew., from Burma, was 

 unique in this respect, but one of the American species, 

 Jractifrous, Cas., has a broken stria, showing a tendency to 

 Jose it. In my example of fractifrons the fourth and fifth 

 dorsal striae are joinecl, but as Casey does not mention this, it 

 may be a varying character both in it and planij'/ons.
