NOTES ON DIPTERA. 



A capsule very similar is constructed of the leaves of Hype- 

 ricum perforatum and H. humifusum, by another Cecidomy'ia, 

 described by IVIr. G. Gene, and figured in the Memoirs of the 

 Academy of Turin, Vol. XXXVI. page 287. 



Psila hicolor, which occurred abundantly in the beginning 

 of August, at Moundstone Bay, in Connanara, appeared to be 

 exclusively attached to Tanacetum vtilgnre. 



Leucopis obscura (Ent. Mag. Vol. I. page 173) is found on 

 larch and lir-trees, at Holywood, in the month of August. 



Opomyza maculata (Macquavt, S. a B. II. p. 558, No. 15), 

 which, as well as Geomyza inarginella (Fallen, Geom. o, 

 No. 5), belongs to the genus Helomyza, is not uncommon 

 among Ehjmus arenarius, on the sandy coasts of the county 

 Dublin. 



Anthomyza grisea (Fall. Agrom. 7, No. 2) is found in the 

 same situations, but very rarely. 



Chyl'iza annuUpes (Macq. S. a B. II. p. oSO, No. 2) was 

 taken in July at Blarney, near Cork. 



Toxoneura fasciata (Macq. S. a B. II. p. 404, No. 1) has 

 occurred at Holywood, and was the cause of n)y erroneously 

 inserting Otites pulchella in a former list. This species 

 should therefore be erased from the Irish Fauna. Toxoneura 

 presents a very trifling modification of the characters of Pal- 

 loptera. The latter genus has been rightly circumscribed by 

 I'allen, but confounded by R. Desvoidy, with several species 

 of Helomyza, in his genus SuilUa, and by Macquart mixed 

 with some hyc'ice. The larvae of the latter are saprophagous, 

 while the Pallopterce breed in flowers, like Trypetce. The 

 generic name Sapromyza, interpreted by etymology, would 

 probably be applicable only to the genera Lycia and Scy- 

 pliella,^ as I have reason to think that the remaining groups, 

 viz. Sylvia, Miiiettia, and Peplomyza,^ are thalerophagous, 

 as well as their near affinities, the Lauxania'. Estelia, 

 (Rob. D.) is synonymous with OcldliipliHa, Fallen, and should, 

 perhaps, constitute a separate tribe. 



Teichomyza fusca (Macq. S. a B. II. p. 5o5, No. 1) is 

 found on the damp walls of old buildings, and Macquart states 



^ With which the Liselhe are not only generically, but, in one case, specifically 

 identical. 



^ Characterised in Vol. I. of this Magazine under the generic name Plujllo- 

 myza, previously employed by Fallen lor another group.
