 distal joint proportionately large and thick, the tip obliquely truncated. 

 Pronotum a little narrower than elytra, Is times as broad as long, with 

 rounded corners, slightly convex, with dense and extremely fine, scarcely 

 vicible punctation, with a transverse fovea posteriorly before scutellum 

 and sometimes a feeble groove in middle-line; elytra a little longer than 

 pronotum, very finely and densely punctated. The first four free dorsal 

 joints of abdomen densely and very finely , punctated, the following with 

 more isolated and still finer punctation; the fifth is much longer than 

 the fourth. L. 2-2.5 mm. 



In the o the sixth free dorsal joint of abdomen (Fig. 75) at tip deep- 

 ly and broadly semi-circularly incised, in the q most often less deeply 

 and more flatly, sometimes only slightly incurved. The next-last ventral 

 joint of the o is somewhat longer than in the <p , rounded off at tip, in 

 the o (?) very feebly emarginate; in both sexes the margin has a fringe 

 of snaall, fine, equally short hairs. The sexes are often difficult to sep- 

 arate . 



Distributed everywhere in Europe and very common; in this country it 



is frequent on all kinds of ground; also at and in ant hills.
