Psocoptera. — These inconspicuous insects were quite numerous, and 
a good selection was obtained mainly by beating. The most interesting 
species taken, however, was discovered by searching among the stones 
by the shore of Eavstone Lake, where the peculiar wingless female of 
Bertkauia lucifuga was found. This species has occurred previously 
once only in the county, when I obtained it in Goredale last year, also 
below stones. The following species were taken : — 
Psocus nebulosus Steph. 
Trichadenotecnum sexpunctatus L. 
Amphigerontia bifasciata Latr. 
Loensia fasciata Fabr. 
Graphopsocus cruciatus L.

Collembola. — Very little attention could be given to these minute 
insects, but the following were noted in passing : — 
Isotomurus palustris Mull. Lepidocyrtus lanuginosa Gmel. 
Orchesella cincta L. Entoniobrya albocincta Tempi.

MAPS FOR RECORDING THE DISTRIBUTION OF 
ANIMALS, PLANTS, ETC., IN BRITAIN. 
We have received from Professors A. E. Boycott, F.R.S. and E. J. 
Salisbury, F.R.S., two convenient octavo maps showing the Watsonian 
counties and vice-counties, with an index relating the numbers which are 
generally used to the names of the divisions. One version is printed 
wholly in black and is intended for record : occurrences may be con- 
veniently put in with red ink, so that the numbers may be read through 
the ink. In the other version the outline only is in black, the county 
divisions, numbers and index being in blue, which will disappear when 
photographed. This is meant for reproduction and reduction ; 
occurrences are marked in black and the map may then be reproduced 
with only the essentials showing. The maps may be obtained from Messrs. 
Oliver and Boyd, Tweeddale Court, Edinburgh, at a reasonable price. 
THE CLOUDED YELLOW. 
C. W. WRIGHT. 
On Sunday, 3rd September, I saw two examples of the Clouded 
Yellow on Ferriby foreshore. They were flying fast, and only alighted 
very occasionally on the Sea Aster. Since the foreshore is the same for 
about four miles there were probably many more examples about.
