 (E. S. R., 23, p. 159) the author considers the Sciophilinse, 12 genera being 

 recognized. Tables are given for the separation of the genera and species. A 

 large number of foi-ms (29 species and 1 variety) are described as new. 



Comparatively little is known of their habits. " Winnertz records rearing 

 Neoempheria, Empalia. and Mycomya from decaying beech wood, the last also 

 from the fungi Doidalea quercina, and Folyporus; Sciophilse (Lasiosoma) were 

 obtained from the fungi Hydnum rcpandum, Boletus scaber, and Dcedalea 

 quercina."
