THE INSECT FAUNA OF THE ISLE OF MAY 89^ 



September and October of the present year on the May 

 Island. Since many of the specimens were captured at the 

 lantern of the lighthouse, it may be of interest to put the 

 whole of the species on record. 



Of Lepidoptera the following species were obtained : — 



Xylophasia polyodon, L. — three at lantern, 9th September ; 

 two at lantern, loth September; one during day, 13th 

 September. Triph(Bna promtba, L. — one at lantern, 9th 

 September; three at lantern, loth September; one at lan- 

 tern, 27th September. Mamestra brassicce, one at lantern, 

 9th September. Cerastis vaccinii, L. — one at lantern, 9th 

 September. Apamea ufianhnis, Tr. — one at lantern, lOth 

 September. Leucania p aliens, L. — one at lantern, loth Sep- 

 tember. Orthosia lunosa, Haw. — five at lantern, loth Sep- 

 tember ; one at lantern, i ith September. Orthosia macilenta, 

 Hb. — one at lantern, 26th September. Charceas graminis, 

 Linn. — one at lantern, loth September ; one at lantern, 

 I Ith September; one during day, 7th October. Agrotis 

 nigricans, Linn. — one at lantern, loth September. Pliisia 

 gamma, Linn. — one at lantern, i ith September; one at 

 lantern, 26th September ; one at lantern, 6th October. 

 Oporabia dilutata, Schiff. — one at lantern, 23rd September. 

 Cidaria testata, L. — two at lantern, 23 rd September. Several 

 other Moths were taken, but these are too much damaged to 

 be determined; on 14th September larvae were found (on 

 cabbage) of Triphcena proyiuba, Linn., and Hadena oleracea, 

 Linn., and on the 19th a small Tortricid Moth (undeter- 

 mined). 



The Coleoptera include Geotrupes stercorarius, Linn. — 



two specimens, loth September; one on 17th September, 

 and one on 19th September. Aphodius contaminatus , Hbst, 

 — one on 17th September; Serica brunnea, Linn. — one 

 specimen taken at lantern, loth September; Harpalus rufi- 

 cornis, Fab. — one, 14th September ; and Pristonychtis terri- 

 cola, Hbst. — one specimen, 19th September. 



The four Hymenoptera captured comprise a number of 

 Ants (males, females, and workers) belonging, I believe, to 

 the mixtns race of Lasiiis umbratus, Nyl, taken on lOth^ 

 I Ith, and 27th September and 3rd October; also two
