joint a little lon^'er than the second; pronotum oblong, anteriorly as 



broad as elytra, narrowing posteriorly, at middle polished, with 10- 



14 punctures in dorsal rows, punctures on sides irregularly soatter- 



ed ; elytra distinctly shorter than pronotum, rather coarsely and not 



densely punctated; abdomen with fine and scattered punctation. L. 10- 



12 mm. 



Distributed in Europe, and not rare in this country under leaves 



on high forest ground, more often taken at the mounds of Formica rufa 



and Lasius fullginosus . The larva is found in Eyrehaven by Cand. Jensen

Closely allied both to the preceding and following species. From 

 tricolor , of which it occasionally is treated as a variety, and with 

 which it corresponds in that the form of the head, although less dis- 

 tinctly, is oviform and broadest posteriorly, it is easily separated 

 by the following deviations; 



It is smaller and narrower and the color is most often darker; 

 pronotum is ordinarily unlcolorous pitch-brown with feeble metal re- 

 flection, or the posterior part is lignter than the anterior; punc- 

 tation of head, pronotum and elytra is comparatively finer. 



From light colored linearis , which it can be like in color, and 

 rather corresponds with in form and size, it differs mainly in that,
