 ribs coarsely, deeply and densely punctated. The first four free dorsal 

 abdominal joints are each, by three longitudinal ridges or sharp cariru.e 

 divided into four deep, square foveae, which at bottom are smoothly glis- 

 tening, the foveae of fourth joint are distinct. Metathorax is at middle 

 deeply grooved and impressed. L. 2.5 mm.

 In the C?the sixth ventral abdominal joint at tip angularly emarginate. 

 Pare, and most often singly in rotting plant waste, in fungi, under 

 carrion and the like; most frequent in woodland regions. Distributed in 

 the greater part of Europe. 



2. M. caelatus Er. 



(Erichs. Kaf, Ilk. Br. I, 647; ien. Spec. Staph. 912; Kraatz Ins. B. II, 

 1053; Thorns. Skand . Col. IV, 196; Janglb. Kaf. M. II, 769). 



Much like preceding species, but a little shorter and more convex, pro- 

 portionately troader, rather glistening; the head and middle of pronotum 

 are more coarsely rugose, middle-line of forehead most often distinctly, 

 even though very finely carinated, pronotal foveae only feebly indicated, 

 and the side-margins at middle less distinctly angulate; elytra between the 

 ribs fully as coarsely, but somewhat less densely punctated than in porcatus . 

 Foveae of the fourth free dorsal abdominal joint are only distinct at base. 

 L. 2 mm. 



Distributed in North an. L'iddle Europe. In this country very rare, in 

 alluvium (v. Lyngby Lake, Stfborg, Soro) ; also found in Skaane (Thorns.).
