 the preceding species; antennae shorter and more robust than in same. 

 Pronotum Is oblong, anteriorly about as broad as elytra, feebly narrow- 

 ing posteriorly, the surface especially finely transversally aciculated 

 and therefore with tempered shine, with 8-10 punctures in the dorsal 

 rows, and as many or mora in the anteriorly curved side-rows; elytra 

 as lon^ as pronotum, rather fine, not dense, at sides row-formed punc- 

 tation, elytra and the very finely and scatteredly punctated abdomen 

 sparsely h&ired. L. 6-7 mm. 



Distributed in Europe, and comracn here in this country, under lea- 

 ves and at rotting plant-matter; not infrequently found with ants, 

 especially Lasius f uli^inosus and Formica rufa , as well inside as a- 

 bout the mound.

In size, form and color much like a n^Tustatus , but v.ith polished 

 pronotum and more glistenin,-^ head, also fewer punctures in the prono- 

 tal punctate rows, furthermore mainly separated from an:ustatus also 

 from punctulatus , in that those on ventral side of head at the mouth- 

 corners issuing lines are not, like in these, confluent at middle, but 

 narrowly separated running side by side down to the neck. 



Black or pitch-black, glistenir,g, pronotum polished; elytra brown 

 or reddish-brown; abdominal tip, often also posterior margins of abdo-
