148 NOTES ON DIPTERA. 



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

 ricum perforatum and H. humifusum, by another Cecidomyia, 

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

 Academy of Turin, Vol. XXXVI. page 287. 



Psila bicolor, which occurred abundantly in the beginning 

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

 exclusively attached to Tanacetum vulgar e. 



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

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



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

 which, as well as Geomyza marginella (Fallen, Geom. 3, 

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

 among Elymus 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. 



Chyliza annulipes (Macq. S. a B. II. p. 380, 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 my 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 

 Fallen, but confounded by R. Desvoidy, with several species 

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

 with some Lycice. 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- 

 phella? as I have reason to think that the remaining groups, 

 viz. Sylvia, Minettia, and Peplomyza } h are thalerophagous, 

 as well as their near affinities, the Lauxanice. Estelia, 

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

 perhaps, constitute a separate tribe. 



Teichomyza fusca (Macq. S. a B. II. p. 535, No. 1) is 

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



a With which the Llsella are not only generically, but, in one case, specifically 

 identical. 



b Characterised in Vol. I. of this Magazine under the generic name Phyllo- 

 myza, previously employed by Fallen for another group.
