Section V. (Phloeostiba, Thomson.) 



This section contains two minute, shining, flat insects, which live 

 under bark ; they are very closely allied to one another ; the margins of 

 the hind body make a considerably wider angle with its disc than^in the 

 other sections. 



I. Form broader ; el^ytra fuseo-testaceous ; thorax with two 



impressions near anterior margin H. PLANUM, Payfe. 



II. torm narrower; elytra fuscous; thorax without impres- 



sioiis in front ti ^,„„^^ m 



xl. PINETI, Thorns, 



H. planum, Payk. Depressed, black, shining, with the elytra 

 fuscous-testaceous, sometimes yellowish, and the thorax occasionally 

 pitchy-red, almost without pubescence ; head triangular, with distinct 

 impressions before ocelli, rather closely punctured behind, almost smooth 

 in iront, eyes very prominent ; antennae dark with the five or six basal 

 joints reddish-yellow, joints 6-10 about equal in breadth, very stron^dy 

 transverse; thorax not much narrower than elytra, very transverse 

 somewhat plainly narrowed Ijehind, posterior angles almost ri<rht an-les' 

 upper surface closely and distinctly punctured with dorsal impress'ions 

 more or less obsolete, but traceable ; elytra about twice as lon^-- as thorax 

 very finely and irregularly, but distinctly punctured, sometimes a 

 little rugose; hmd body very finely shagreened ; legs testaceous. L. 

 2-2 1 mm. 



H. pineti, Thorns, {lapponicum, Zett., snMile, Kr., conforme, Kr ) 

 Very hke the preceding, but smaller and distinctly narrower with the 

 elytra considerably darker ; the thorax has no impressions on its anterior 

 margin (a character that will easily distinguish it), and the elytra are 

 evidently more finely and sparingly punctured. L. 2~2\ mm.

The name lajyponicum, Zett., has priority, but cannot stand as Man- 

 nerheim had, prior to Zetterstedt, described another RomaUum under 

 that name. 



Section VI. (Sub-Gen. Etheothassa, Thomson.) 



_ This section contains three species, the first two of which are found 

 in liaystack refuse, bottoms of corn bins, &c., while the last aiipoars to 

 occur m rotten wood ; they may be distinguished superficially by their
