46 DIPTERA OF AUSTRALIA, 



rejecting the genus. Even if Anarete is not a doubtful genus, it 

 cannot be received into this family. 



In 1870, Winnertz (Verh. z.-b. Ges. in Wien, XX.) published a 

 paper on these troublesome species, and located them in a separate 

 group which he calls by the old name LESTREMiNiE, and he admits 

 the genera Gampylomyza, Micromyia, Catocha, and Lestremia. 

 They consist, in his opinion, of transitional forms between the 

 Cecidomyidae and the Mycetophilidoe, differing from the former 

 by the existence of ocelli, in the not shortened tarsi (with only a 

 few exceptions), and in the more elaborate vein-system of the 

 wings. And, as in Campylomyza and Aficromyia, the species ap- 

 proach the section Cecidomyina ; so they form a natural transition 

 to the Sciaridse by the ocelli, which are extremely small in Lestremia. 

 Now all this seems to point to a separation, but I cannot discon- 

 nect Campylomyza or therefore Micromyia (which latter I regai'd, 

 with Dr. Schiner, as belonging to Camjyylomtjza) from Ceci- 

 domyidse ; an examination of the antennee, venation of the wings, 

 and the habits of the insects themselves would alone preclude 

 that. Time may reveal to us new forms which may bridge over 

 the gap between the two sections, or have the reverse effect ; but 

 for the present, I for one, shall include Lestremina as a sub-family 

 of Cecidomyidaj ; not omitting from it Loew's Tritozyga, an 

 imdoubtedly well-marked genus approaching Campylomyza. 



A large number of genera in both sections, by different authors 

 have been disallowed for various reasons ; but it is unnecessary to 

 mention them all here. Villigera even turned out to be a Coccid 

 and no Cecidomyid at all ! However by some chance (probably not 

 having seen the publications), I may here unfortunately omit good 

 genera, but should that be so I am sure the number would be very 

 small. I have never seen more than the name of Stephen's 

 Dlomyza, and so am compelled to exclude that genus from want 

 of information. 



I shall divide the Cecidomyidse in the first place into two sub- 

 families Cecidomyina and Lestremina, and the whole may be 

 taken as follows : —
