 pression before the scutellum. ilytra^/jf longer than pronotum, sli^^htly 

 convex, with dense and distinctly scabrous punctation, inside the outer 

 hind corners flatly, yet distinctly incurved; abdomen slightly narrowing 

 posteriorly, its first three, free dorsal joints finely but not densely, 

 the followin^i two very simply punctated or almost smooth. L. 2.5-3 mm. 



In the o the posterior margin of the sixth free dorsal joint of ab- 

 domen at middle v.ith a rather deep obtuse angular incision; the next-last 

 ventral joint is tapering and rounded off at tip (Fig. 54). 



Distributed but not frequent. It is found at fungi, under leaves and 



fagot and in hollow trees; a few times I have encountered it by or in ant 



hills ( Formica rufa . Lasius f ullginosus ) .

Closely allied to sodalis . from which It easily is separated oy the
