30. Genus Mycotlicra Winnertz. 



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

 Front broad, its anterior margin produced into a triang'f, 

 the apex of which 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 sette strong, the middle 

 tibia frec|uently with one or more on the flexor ourface, fore 

 metatarsus shorter than the tibia. Costa not produced beyond 

 the ti]) of Rs, cubitus 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 parallel branches of the cubitus separate it from 

 Bpicypta. The larv?e live in decaying wood and fungi.
