A peculiar, rather small species, easily identified by form and 

 bronze lustre of the body, and by the coarse punctation of the thorax. 



Thorax darkly bronze colored, glistening, often with greenish re- 

 flection; abdomen black with metallic lustre, together with elytra with 

 very short and sparse hair vestiture; antennae distally toward tip, and 

 the legs, especially tibiae and tarsi, brownish or brownish-red. 



Short and broad (Fig. 172); the head narrower than pronotum, both 

 with coarse and rather dense punctation, antennae rather short, their 

 middle joints almost rounded, the three last (£-11) somewhat club-formed 

 set off; pronotum (see above) narrower than elytra, much broader than 

 long, with two distinct, short impressions posteriorly and smooth middle- 

 line; elytra somewhat longer than pronotum, somewhat denser and coarser 

 punctated than this, inside humeri and at suture most often feebly im- 

 pressed; abdomen nearly impunctate, surface particularly finely shagreen- 

 ed. L. 2.5 mm. 



On marshy and damp forest ground under moss and leaves; rare and most 

 often singly, rarely in numbers (/bjerggaard at Naestved, Lillerpd; ?ug- 

 ballegaard at Vejle, Lundbykrat at Aalborg and other places).

 roll itself up globular, and is slow in motion like the beetle, with which 

 It has mutual abode.
