Tctanoccra elata, Fab.— Glengariff, Juue 12, 14, and 15 ; Ardgroom, 

 July 20 ; Keumare, June 27 ; Parknasilla, July 12 ; Waterville, 

 July 28. Common. 

 T. laevlfrons, T^oew— Glengariff, June 12 to 21 ; Parknasilla, July 13 



and 17. Ver}- common at Glengariff. 

 T. fcrruglnea, Fall.— Loo Bridge, both sexes, June 29; Ardgroom, 

 July 20 ; Waterville, July 26 ; Caragli Lake, Aug. 13 ; Glencar, 

 Aug. 16. Apparentl)^ uncommon. 

 T. rotousta, Loew— Glengariff, both sexes, June 12 ; Loo Bridge, 



July 6. Rare. 

 T. coryletl, Scop. {Pherbina coryleti, Hendel).— Kenmare, July 2 ; Loo 

 Bridge, June 29 ; Parknasilla, July 14 ; Waterville, July 30 and 

 Aug. 3; Caragh Lake, Aug. 14; Glencar, Aug. 16. Common, and 

 generally distributed, though it was not taken at Glengariff. This 

 species is the T. retiaUata of VerraU's List, but should, apud Hendel 

 ( Verh. Z.-b. Gesell. IVien, Band 1., p. 347, 1900J, stand under the head 

 of T. joryleti, Scop.— the T. coryhti of VerraU's List being probably 

 T. charophylii, Fab. {Lunigera chcRrophylii, Hendel), a doubtfully 

 British species. 

 T. umbrarum, Linn. {Monochcetophora umbrarum, Hendel). — Kenmare, 

 July 2 ; Parknasilla, July 17 ; Ardgroom, July 20 ; Waterville, 

 Aug. 13. Not common. 

 T. punctulata, Scop. {Jrypetoptera pnnctiilata, Hendel). — Glengariff, 



Juue 19 ; Kenmare, June ,28 ; Parknasilla, July 12. Uncommon. 

 T. unlcolor, Loew — Cloonee, July 3. Only specimen. 



In the Tetanoceriuae four genera {Tetanocera, Limnia, Elgiva, and 

 Sepedon) have heretofore been considered sufficient, but should we 

 decide to follow Hendel {Verh k.-k. Zool.-bot. Gesell. Wieu, 1900, 

 Band 1., p. 319, and Term. Fjiz.^ xxiv , 1901, p. 138) we shall require 

 twelve genera or sub-genera Whether in our present knowledge of 

 the Diptera of the world this splitting up is advisable is a matter in 

 which there is room for considerable difference of opinion. Many 

 of these genera are monotypical, and some of the names, e.g:.^ 

 Renocera, do not seem to have been happily formed. 

 Llmnla ungrulcornls, Scop. — Glengariff, Juue 14 and 15 ; Cloonee, 

 July 3 ; Kenmare, June 30, July 7, and Aug. 23 ; Loo Bridge, June 29.

£• dOrsaIls» Fab. {Hydromy^a dorsalis, Hendel.— Glengariff, June 13

 Kenmare, June 30, had three inmature ticks attached to the thorax, 

 hear the base of the wings.
