1902 Yerbury. — Diptaa from Cork and Kerry. 89 



Coelopa grravis, Hal. ?~Waterville, July 27; Glengariff, June 20; 

 Glenbeigh, Aug. 17. Common under marine rejectimenta. A speci- 

 men taken at Loo Bridge, June 29, seems to have got off its beat. 

 This genus requires thorough overhauling. A long series will pro- 

 babl}' show a complete gradition without break from the large form 

 C. gravis, Hal., through C fn'gida, Fall., to the small form C.parvula, 

 Hal., in which case all the forms will have to stand under the name 

 of Cfflopafrigida of Fallen. Further, Mr. Collin informs me that the 

 generic name Ccelopa will probably have to be restricted to C. pi/ipes, 

 Hal., while C.frig^ida and its varieties will have to stand in the genus 

 Fucomyia. 



HELOMYZID^. 



Helomyza rufa, Meig.— Parknasilla, July 17 and 21 ; Caragli Lake, 

 Aug. 13 ; Valencia Island, Aug. 20. This species [11. variegata of 

 Verrall's List) is not uncommon on decaying fungi. 



H. pectoral is, Loew — Valencia Island, Aug. 9. The only specimen. 



H. Zetterstedti, Loew— Parknasilla, July 21 ; Waterville, Aug. 4 



Blepharoptera sp. inc. — Kenmare, June 26. Two specimens given 

 to Mr. Verrall as indecipherable. Apart from the natural difficulties 

 attached to the genus, these specimens had suffered much from 

 grease. 



Tephrochlatnys i-ufivcntris, Meig. — Glengariff, June 12.

SCIOIYIYZIDVE. 



Actora aestuum, Meig.— Darrynane, July 31. Probably common on 

 all sandy shores. 



Dryonnyza anilis, Fall. -Parknasilla,July 17. Apparently uncommon. 



D. flaveola, Fab. — Glengariff, June 12 and 24 Uncommon. 



Sclomyza albocostata, Fall.— Glengariff, both sexes, June 12, 15, 

 and 18. Rare. Waterville, Aug. 3. 



S. cinerclla, F'all.— Kenmare, June 27; Darrynane, July 31 ; Water- 

 ville, July 27. Rare. 



S. Schcenhcrri, Fall.— Glencar, Aug. 16; Loo Bridge, Aug. 28. Un- 

 common. 



S. pallida. Fall. {Renocem, Hendel.) Parknasilla, July 24; Kenmare, 

 Sept. I. Rare. These two specimens undoubtedly belong to the 

 species which we in England are accustomed to call S. pallida, Fallen, 

 but it is equally certain that they belong to Renocera sintenisiana, 

 Hendel (F<?;-/e, Z.-b. C^^^//. ^F?^«, Band 1., p. 347, 1900). Renocera s^^vas 

 to be a good genus, linking Scioniyza with Tttanocera through T, unicolor 

 It would be interesting, however, to know in what way, if any, the 

 insects we know in England as S. pallida and S, fiiscinervis ,'L^\X., differ 

 from R. sintenisiana and R, strobli. Our English insects appear to be 

 correctly identified, and the former is (in England at any rate) so 

 common, that any doubt about its correct identification appears to be 

 impossible.
