8—10. Symplecta, Rhamphidia and Cylindrotoma do 
not require any particular remarks. 
11. Taphrosia Rond. — Gonomyia (Megerl.) O. 8. 
12. Orosmya Rond., type O. appennina n. sp. indeser. I can- 
not make out what it is, and did not find the type. 
13. Ilisia Rond. Type Eriopt. maculata Meig. The untenable 
character of this genus becomes apparent from the development which 
it receives from the author himself in his Dipt. Exot. (Archivio 
Canest. IH, fasc. 1) where he says: „Species typicae europeae Erio- 
ptera maculata et Limnobia fimbriata." Now E. maculata be- 
longs to my subgenus Acyphona; while L. fimbriata is the same 
as L. pilipes Fab., which is a Trimiera, two very distinet and 
distant forms, In the same article, Rondani places in the genus 
Jlisia the Limnob. hirsutipes Macq. (Canary Isl.), which is likewise 
a Trimicera. 
14. Elaeophila Rond. — Ephelia Schiner. 
15. Limnomyia Rond. (see corrigenda Vol- IV) is proposed 
as a substitute for Limnophila Macq., preoccupied in the Mollusca. 
16. Bophrosia Rond. — Trieyphona Zett. (see Rondani, in 
Erratis). 
17—22. These are well known genera that give no occasion for 
any remark. 
23. Pelosia Rond. (preoce. Hübner Lepidopt.), type P. albifrons 
n. sp. indeser.; I cannot make it out; it may be a Dieranomyia 
with an open discal cell, or else Orimargula Mik. Lioy’s statement 
(I ditteri etc. p. 431) that it is allied to Diwa cannot be accepted, 
because Rondani distinctly says that the antennae are verticillate 
which is not the case with Dixa. 
24. Glochina Meig. in Rondani’s sense answers Dieranomyia, 
but it does not appear why he separates it from his Limnobia, 
which also answers Dieranomyia. 
25. Taphrophila Rond.; type Limnobia inusta M. Again 
a case of erroneous determination of the type-specimen, because, 
Taphrophila is said to have no marginal crossvein, while .ZL. inusta 
has one. In Florence I found a label, bearing 7” inusta M. but the 
specimen was destroyed. In Mr. Bigot’s collection Zaphrophila was 
represented by a specimen of Antocha. And indeed the characters 
given in Rondani’s analytical table, the absence of the marginal 
erossvein and the coalescence of the auxiliary and first veins answer 
Antocha. 
26. Limnommyza Rond., type L. tripunctata M., is a Lim- 
nobia sensu stricto of ©. 8,
