 with smoothly rounded sides, not narrowing posteriorly, slightly convex, 

 finely, but not densely punctated, in the S^ often with a broad, flat long- 

 itudinal impression at middle posteriorly; elytra only a little longer 

 than pronotum, finely and not densely punctated; abdomen anteriorly with 

 fine and sparse, posteriorly simple punctation; its fourth and fifth free 

 dorsal joint of same length. L. 3.5-4 mm. 



In the 3' the sixth free dorsal joint of abdomen posteriorly evenly 

 truncated or feebly rounded and in margin indistinctly undulate-serrate. 

 The next-last ventral joint is a little longer than in the j^ and rounded 

 off at tip. 



Distributed in Middle Europe, England and Finland; in Denmark rather 



common on damp forest, meadov. and marshy ground under leaves and other 



plant cover, also in alluvium at the brim of lakes and brooks. Light, 



fully colored specimens with entirely brown antennae occur, but are rarer.

(Kraatz Ins. D. II, 211; Thorns. Skand. Col. Ill, 64; Sharp Pev. Brit. 

 Horn. 129; Wuls. et Fey Bre'vip. 1873, 620; Janglb. Kaf. M. II, 171). 



Very closely allied to, and often so much like oblonga , that the spe- 

 cific differences are difficult to prove. In well marked forms of nitidula 

 the head and pronotum are more strongly glistening than in oblongo; the 

 head with finer punctation and not flatly depressed in the O , antennae 

 more slender and longer, pronotum more convex and a little longer, elytra 

 more densely punctated; as a rule somewhat larger. 



Black, strongly -jlisteninj, finely haired; elytra pitch-brown or yel- 

 lowish-brown; antennae unicolorous black or brownish at base; legs brown- 

 ish-yellow, femora often darker.
