 curved upward and forward. In the o the fifth and sixth free dorsal joint 

 with diversely fdrmed sex-characters. The legs fine; fore- and middle-tibiae 

 4-jointed, only hind-tarsi 5-jointed, and the first joint of these 1^ times 

 as long as the second. 



The species live in fungi, often in colonies. From Middle and North Eu- 

 rope 16 specie^ are known, of which the majority are found in this country. 

 - Several of the species are difficult to separsite, and as in cases of un- 

 certainty the sex-characters furnish the most difinite identification marks, 

 an abundance of specimens in both sexes is important for the determination.
