 temples and genae finely margined; antennae short, robust, their outer 

 joints strongly transverse; maxillary palpi rather slender, their last 

 joint fine, spiculiform, only half as long as the third; labial palpi only 

 two- jointed; the tongue very short and broad, roianeJed at tip.

Pronotum broad, as broad as or a little narrower than elytra, its pos- 

 terior margin inside the obtuse-angular corners most often slightly in- 

 curved; abdomen flat, feebly tapering, its first three free dorsal joints 

 very narrowly transverse-grooved depressed at base, the fifth longer than 

 the fourth; the sixth in the <?with sex-characters; legs rather short and 

 not robust; fore-tarsi and middle-tarsi 4-jointed, only hind-tarsi 5-joint- 

 ed and first joint of these elongate, almost as long as the following three 

 joints together, as long as the clav,-jolnt. 



The species, which at a casual glance mostly resemble Homalota species, 

 live under the bark of deciduous and pinaceous trees, which are infested 

 with bark- and bast-borers, the young of these presumably serve as food 

 for the species and their larvae. In Middle and North Europe 6 species are 

 known, of which only 2 are heretofore found in Denmark, but as it is not 

 unlikely that several more may be found here, 3 of these are included in 

 the following. 



Key to the Species. 



1. Head and pronotum entirely dull 2. 



Head and pronotum rather glistening 3. 



2. Posterior margin of pronotum very finely marginated, its hind corners 



roundly obtuse-angular. L. 2-2.5 mm 1. PI. humilis Er.
