Oval, little convex above, black, shining, sparsely and very finely punctulate 

 above and beneath ; the forehead, feebly impressed in the middle, lateral stria in- 

 curved at the angle before the eye, interrupted on either side, anteriorly bent ; the 

 thorax, lateral stria well marked, interstice narrow and even in width throughout, 

 stria continued behind the head ; the elytra, dorsal striae 1 — 3 complete, but the 

 second is a trifle shorter than the first and third, 4 — 5 apical, the fifth occupying 

 one-third of the elytra, the fourth a little longer, the interstice between the fifth 

 and suture is wider than that between the fourth and fifth striae, epipleura bistriate ; 

 the propygidium, transversely punctured ; the pygidium, transversely excavated on 

 either side at the base, the excavation being surrounded by a triangular depression, 

 central area is a little coai'sely, but not quite densely, punctured, apical margin 

 narrowly smooth but not raised ; the prosternum, anterior lobe punctulate, keel 

 with well marked lateral striae, striae straight before the coxae, widening out between 

 them, not joining at either end ; the mesosternum, feebly sinuous anteriorly, stria 

 complete and continuing down the metasternum ; anterior tibiae 5 — 6 denticulate. 



The prosternal stria3 in this species resemble those of P. striati- 

 pectics, Mars. ; but in its general facies and elytral striation P. sh^ia- 

 tlsfernuin is similar to P.frontosum, Mars.

HiSTER EOBUSTICOLLIS, sp. 11. 



JBreviter ovatus, convexus, niger nitidus ; H. amplicolli simillimus sed 

 thorace margine ciliato et prosterno fortiter carinato. Elytris 3-striatis. 



Length, 9 mm. 



Short-oval, convex, black, shining ; the forehead, punctulate, stria complete, 

 straight anteriorly, a feeble median depression behind the stria ; the thorax, ciliate 

 at the sides and front, finely punctulate, external stria abbreviated before the pos- 

 terior angle, internal feebly sinuous, inflexed before the base, and continuing round 

 the anterior angle to a point just beyond the level of the eye ; interstice somewhat 

 similar to that of H. ampllcollis, Er. ; the elytra, punctulate like the thorax, 1 stria 

 is complete and fairly well marked, 2 and 3 also complete but very fine ; the 

 propygidium, a little sparsely covered with moderately long punctures ; the pygi- 

 dium, punctures rather larger and a little more thickly set ; the prosternum, a 

 little prominent and carinate before the coxae, the outline viewed sideways is arched, 

 or almost semicircular in outline, between the coxae the sternum is cone-shaped, 

 with short lateral striae, which meet at the vertex in a sharp point ; the mesosternum, 

 clearly emarginate, the marginal stria complete ; the anterior tibiae tridentate, the 

 apical tooth being very robust. 



In structure this species is very similar to the well-known Euro- 

 pean species, H. grandicollis, 111., and ampIicoUis, Er. In the pro- 

 sternal keel it is most like the first, but in the elytral striae it agrees 

 better with the second.
