surface also in P. rumanice is less closely punctured, and 

 some of tlie punctures near the scutelluni are much larger 

 tlian those of P. discisus. Beneath, the differences are 

 greater. The anterior prosternal lobe is smooth and convex 

 (similar to that of nitidus, Horn) and slightly sinuous on 

 either side of the anterior margin, and the median canalicu- 

 lation of the metasternura is wide and deep throughout its 

 course and markedly smooth. The anterior tibise also are 

 dilated abruptly, not rounded off like those of P. discisus. 



The anterior lobe of the prosternura of P. discisus is very 

 clearly and closely punctured, but this character is not noticed 

 by ]\Iarseul in liis monograph of 1856, p. 272.

Saprinus cceruhatus^ sp. n. 



Circularis, convexiusculus, cseruleus, antennis pedibusque rufo- 

 brunneis, supra undique dense strigosus vel puuctatus, striis 

 dorsahbus (subhumerali et suturali exceptis) obsoletis ; pygidio 

 dense punctato. 



L. 3 mill. 



Almost circular in outline, rather convex, blue, and some- 

 what shining; the head is densely and rugosely punctured, with 

 a lateral stria over the eyes only, there is a slight impression 

 on the vertex ; tlie thorax, marginal stria complete, surface 

 rugosely punctate behind the head, markedly and densely 

 strigose on tlie other parts ; the elytra, stria3, outer humeral 

 fine and complete, continuing along the apex and joined to 

 the sutural, which is obliterated by the sculpture close to the 

 scutellum, there are several indications of striaa on the 

 humeral area, the oblique humeral being the most distinct, 

 the surface is densely and rugosely punctate and is without 

 the marked strigosity of the thorax ; the pygidia are densely 

 punctate ; the prosternum, the keel is widely sinuous laterally, 

 with microscopic strigosity and irregular punctures on its 

 surface, the base widens out and is hatchet-shaped, the 

 striae do not follow the outline at the base, but they are 

 similarly joined before and behind in the form of an arch ; 

 the mesosternum is nearly straight anteriorly, but the marginal 

 stria is widely sinuous, the surface has shallow punctures, 

 not closely set, on the metasternum the points are smaller ; 

 the antenna3 are reddish brown, with the club and scape 

 darker. 



I do not know of any species similar to this.
