Family SCIARID^E 



These small flies are separated from the Mycetophilidae 

 by several dipterists and are easily recognized by the vena- 

 tion and much shorter coxae. 



The larvae are scavengers but some do damage to mush- 

 rooms. Many species breed in leaf mold.

 certainty without male specimens; some are probably undescribed.
