30. Genus Mycothcra \\'innertz. 



Verh. Zool.-bot. Ges. Wien XIII. 913, 1863. 

 Front broad, its anterior margin produced into a triangVr. 

 the apex of whicli reaches to the base of the antennae; ocelli 

 small, the laterals contiguous to the eye margin, the minute 

 middle one placed in a groove at the base of the frontal triangle. 

 Anal segments and forceps small. Tibial set;ie strong, the middle 

 tibia frequently with one or more on the flexor surface, fore 

 metatarsus shorter than the tibia. Costa not produced beyond 

 the tip of Rs, cul^itus forks proximad, at, or distad of the base 

 •of Rs, the branches convergent or parallel toward their apices 

 The 3 ocelli distinguish this genus from Mycetophila, the con- 

 verging or jiarallel branches of the cubitus se]iarate it from 

 Ejricxjita. Th.e larvae live in decaying wood and fungi.
