330 Mr Brindley, The proportions of the sexes 
sand as well as a large beach on its N.E. side. The comparatively 
few earwigs were chiefly under stones on the sand near the margin 
of the turf. High males were not infrequent, but there were more — 
small-bodied individuals than on the two above islands. 
St Martin’s—This inhabited island is well cultivated on its 
S. side, where the slopes are cut up into small root fields and 
pastures by numerous stone walls. There are Hscallonia shelter 
hedges at the S.W. end. The higher land is largely pastures. 
The'second highest point in the islands is on St Martin’s, a spot 
160 ft. high at the E. end, on which the Day Mark is erected. 
Karwigs were numerous in the stone walls. They were on the 
average much smaller than those of the islands already mentioned, 
and “low” males were common. The sand beaches on the N, | 
side were not searched. 
_Northwethel.—This islet resembles Tean in its general features, 
but has less turf and more blown sand. EHarwigs were not very 
numerous and all were found under stones lying on the sand. In 
size they resembled the specimens from Tean. 
Tresco.—This large and inhabited island is chiefly pasture | 
with many root fields, and it possesses a special feature in the — 
sub-tropical gardens of The Abbey at the S. end. Collections — 
were made in two localities. (i) New Grimsby, the western village. 
Earwigs were fairly abundant in the stone walls above the houses 
and very numerous in the scattered pieces of rotting wreck wood — 
lying on the turf near the beach. Breaking open the wood with . 
a chisel turned out swarms of earwigs. The majority had large 
bodies and “high” males were common: “low” males were much 
more frequent than on Round Island. (11) The Abbey Gardens. 
Here earwigs have been caught for me for three successive years 
by Mr James Jenkin, the head gardener. They do not appear to 
be specially numerous, and, compared with those from New — 
Grimsby, half a mile distant, they are small-bodied, with few 
if any “high” males. 
Bryher—This island is inhabited and is chiefly pasture with 
scattered stones and a certain number of root fields. It has one 
turfy hill. Earwigs were caught in numbers under stones in and — 
near the cultivated fields and less abundantly under stones on the 
turf. They were of medium size, and the “high” male was not | 
conspicuous. 
Samson.—An island composed of two turfy hills with scattered — 
stones. Each hill is about 100 ft. high. They are divided from 
each other by an extensive beach of blown sand with numerous 
stones which runs across from shore to shore. There is a wide belt — 
of very thick and high bracken on the E. side, in and near which 
are the ruins of four or five houses, one of which was inhabited till 
1855. Salsola kali is abundant on Samson. The island is now
