 and in the cleft the last (tenth) joint is visible; jn the Q the ninth 

 (next-last) joint is entire, and the tenth (when the tip is not drawn

 all tibiae finely spiniferous, fore-tarsi in both sexes simple. 



Of those in North and Middle Europe distributed species, 9 or 10 

 are found in Denmar><. The majority of these live under leaves and mosr;, 

 or in compost, and at rotting plant-matter, a fev. are found with ants 

 or under the bark of attacked trees. In danger the Xantiiollnids seek 

 protection by "lie dead" they fold themselves up by bending ^^^ thorax
