given to her young master, a boy who was making a collection. He, in

schoolboy fashion, stuck it unset into his box, and, having tired of the whole thing, it was handed over to me." From this it is clear that the

insect was captured in County Antrim, and not in County Down. The

entry in the County Down list should therefore be deleted. This account by Mr. Bristow shows a further error in the very statement

of the case given in the 1902 Guide, as it is stated there that the butterfly was actually captured by Rev. Canon Bristow, whereas we know that such was not the case.

A third error in this connexion is that Kane (Lepidoptera of Ireland), at page vii of the preface and at page 10, gives Canon Bristow's name as "

James." It should be "

John."

BOTANICAL NOTES.

INFLUENCE OF AIR TEMPERATURE ON DATE OF FLOWERING OF HAZEL AND ELM.

A Hazel tree has been observed for the past five years. Previously there has been <a gap of six to ten days between the date at which the first

male catkins shed pollen and the date of the female flowers opening. In 1932 the dates were January 14th and January 20th respectively.

The latter part of last December and the first four days of January were mild for the time of year, and the male catkins commenced to shed

pollen on January 6th. At the time it looked as though the female flowers would open about a week later, but a cold spell set in that lasted until

January 20th, and it was January 21st before they were ready to receive

pollen. Another mild spell commenced on February 1st, lasting until February

10th, and the Elm tree that is observed each year flowered on February 9th.

During the past five years the earliest date of flowering was March 1st.

Early flowering of Elm trees appears to be common in the vicinity of Cork.

Cichorvwm Intybus L. A fine plant was brought to me from the Spring field Road, Belfast, where only the one specimen could be found.

Gomphonema geminatum (Lyngb.). This diatom was very abundant in one place in a stream just above Dunteige Bridge, above Bally gaily. West

{Trans. R.I.A., v. 32, p. 84) records this species from Ram's Island, Lough Neagh. Elsewhere, it has been recorded from Cos. Mayo, Galway, Kerry, Donegal and Wicklow. Miss Knowles kindly named the specimen for me.
