(Pa-e 4c) 

 Ecutellum, occasionally also feebly grooved in middle-line; elytra '/^ long- 

 er than pronotuD, more distinctly and densely punctated than this, their 

 posterior margin inside the outer corners strongly incurved; abdomen al- 

 most of equal breadth or only tapering posteriorly, all over extremely 

 finely and densely punctated with distinct silky gloss. Kind tarsi long, 

 as long as tibiae, their first Joint as long as, or some-Ahat longer than 

 the two following joints together. L. 6-^.5 mm. 



0. spectabilis US'rk. is a developed, darkly colored variation of 

 ruf icornis , in which the elytra has a mutual, large triangular, black 

 spot on base and along the suture, the outer hind corners are dark, and 

 first joint of the antennae nearly pitch-black, tip of abdomen, and pos- 

 terior margins of its joints are reddish-brown.

0. ruficornis is distributed, but rather rare in forests, groves and 

 gardens, under semi-damp, deep leaf mould, or at fungi, in hollov. trees 

 and like places. The dark variation, which namely is said to occur in com- 

 pany with the black ant, Lasiue fuliginosus , is very rare.

(Mannh. Erach. 70; Thorns. Skand. Col, III, 18; WuIb. et Pey Er^vip. 

 1874, 237; ;anglb. Kaf. M. II, 62. - luteipennis Erichs. Kaf. I.!k. Br. I,

It bears considerable likeness v;ith ruficornis (var. spectabilis ) , 



but is somewhat smaller, more flwtly convex, anteriorly and posteriorly 



moro t'tpe'lng; the color of elytra is more livid, antennae, and especially 



hind tarsi distinctly shorter.
