 flat, foveiform impression inside each of these, side-margins behind mid- 

 dle narrowly set off. Elytra l£ times as long as pronotum, punctated as 

 this; abdomen not distinctly punctated, but the surface is very densely 

 shagreened. L. 2.5-3 mm. 



Very rare; under bark, in wood-crumbling s and at outflowing sap of 

 trees. (Sortf, Naesbyholm; Odense; Iladerslev, Lindum Forest south of Ho- 

 bro). 



Very closely allied to Ph. plana is lapponica Zett. ( plneti Thorns. 

 Omalium conforme Kr. and subtile Kr.). It is smaller and narrower, and 

 most often of darker color, furthermore with much finer and more scat- 

 tered punctation, the bosses on fore-margin of pronotum are not distinct. 

 L. 2-2.5 mm. It is found in Skaane and Middle Europe under the bark of 

 infestea pinacious trees, especially fir, and may be encountered also in 

 Denmark.

(Heer Faun. Helv. I, 184; Thorns. Skand. Col. Ill, 21C; Pey Brevip. 

 188C, 179; dang lb. Kaf. M. II, 731). 



From the very closely allied preceding genus, with which Phloeonomus 

 namely has this in common, that the distal joint of maxillary palpi is dis- 

 tinctly narrower than the next-last, and that the tarsal claw-joint is 

 more than twice as the especially short first four joints together, - it 

 is separated especially by, that pronotum (like in Omalium ) has two deep 

 or flat longitudinal impressions at middle, and a flat or nearly obliterat- 

 et one on each side; grooves of the forehead before the ocelli are short, 

 almost punctif ormis, and the set off side-margins of abdomen more or lass 

 upturned.
