We were, nevertheless, somcwhat surprised by the weal th and abundance : of Tenerifc's Rhopalocera; indeed, we were so successful early on that only one additional species (V. oralanta) was procured .: after July 23rd; thus the bulk of our time thereafter was concentrated on our quest for V. virginiensis and D. chrp.sip- pus.

The specimen was determined by D. S. Fietcher of the British Museum (Natural History) as Oligia versicolor (Borkh.). In his "Revised Catalogue of Irish Macrolepidoptera" (1964). Baynes refers to only one other Irish record of this species, dating from 1903. 1 am not awate of any more recent record of this species in Ireland. - K. G. M.
