many more species, and probably genera, will yet be dis- 

 covered belongnig to the sub-section Mycetobince. Generally 

 the Mycefophilida are excessively abundant in the colony* 

 owmg probably to the great extent of damp bush-covered 

 country, and wherever search is made new species are dis- 

 covered m comparative plenty. 



The following is a restcme^ taken from Skuse's " Monocrraph 

 of An^tv'a.h^n MycetophilidcB,'' of Winnertz' classification of 

 tne lamily. Only those genera are described that have so far 

 been shown to possess representatives in this colony. Where 

 genera of my own are mentioned their probable relation to 

 other genera is indicated. 



Section I.— Second longitudinal vein arising from the fourth 

 longitudinal vein, at the middle of it, or more or less before 

 the middle of it. Marginal cross- vein elongated, very 

 obliquely situated. Inner marginal cell dilated. Anterior 

 branch of the second longitudinal vein seldom missin^ 

 [m Biadocidia only). Anterior branch of the fourth lonaj! 

 tudmal vein issuing from the base of the second longi- 

 tudinal vein. Fifth longitudinal vein generally perfect 

 Ocelh on the front. " 



Section II.— Second longitudinal vein arising from the fourth 

 longitudinal vein near the root of the wing. Marginal 

 cross-vem not elongated. Inner marginal cell not dilated 

 Anterior branch of the second longitudinal vein always 

 present, very small, situated very near the marginal cross- 

 vein ; consequently the marginal cell is very short An- 

 terior branch of the fourth longitudinal vein issuincr from 

 the fourth longitudinal vein bej'ond, at, or before the 

 middle of it. Fifth longitudinal vein incomplete Three 

 ocelli on the front. 



Section III.— Second longitudinal vein, marginal cross-vein 

 hfth longitudinal vein, and inner marginal cell as in' 

 the last section. Anterior branch of second lon^ritudinal 

 vein always missing; therefore only two submargiual cells 

 Anterior branch of the fourth longitudinal vein arisin-' 

 from the fourth longitudinal vein beyond, at, or before the 

 middle of It, rarely missing, more rarely still the anterior 

 branch of the third longitudinal vein missin<r OcelU 

 three or only two-namely : (A) Three on the front • 

 (±5) three, one on the inner margin of each of the com- 

 pound eyes, the third always very small, situated in 

 the middle of the anterior margin of the front • (C) 

 two, one on the inner margin of each of the compound 

 eyes.
