 most smoothly rounded sides and incised hind corners, the incision forms 

 with the side-margin an obtuse, with posterior margin an acute angle, the 

 corner of which is sharply, almost dentiform. Slytra about twice as long 

 as pronotum. L. 2.5-3 mm. 



In the J> the middle and hind femora are thickened, middle-tibiae 

 slightly curved, the trochanter of hind legs at middle of inner rim feeb- 

 ly dentate, hind tibiae on inner side above the middle strongly dentiform 

 dilated, and at middle deeply emarginate; sixth ventral abdominal joint 

 feebly, the seventh deeply semicircularl„ incurved. (Kraatz and Janglb.). 



Distributed; in Middle Europe rather frequent in decaying fungi, in 



North Europe (Sweden) very rare; in this country not unlikely, heretofore 



however not found. 



123. Cienus Phloeobium Er. 



(Erichs. £en. Spec. Staph. 907; Kraatz Ins. E. II, 1C32; Muls. et Fey 

 Bre'vip. 1878, 254; ianglb. Ka'f. M. II, 764. - fJetopsia "/oil.). 



Very closely allied to Megarthrus , from which it mainly is separated 

 by, that the head is much broader, strongly transverse, and with an ocellus 

 at middle of vertex; the temples are rather long, strongly oblique inwards, 

 eyes rather small, clypeus broadly flattened out, anteriorly flatly eraargi- 

 nated, side-margins of forehead before the eyes dilated into a rounded, 

 short lobe, which is separated from the fore-margin by a small, narrow in- 

 cision (Fig. 191). Pronotum is very strongly transverse, as broad as elytra, 

 with broadly set off, flat sides and flatly incised hind corners, in midd- 

 le-line finely grooved; elytra, legs, and sex-characters cf O about same 

 as in Megarthrus . 



To this genus only 1 middle European species, which also if found here.
