amples of A. brunnea, A. proxima being for a long time 
mistaken for it. In spite of the frequent occurrence of the 
little egg-cocoons referred to, as well as of the last-mentioned 
spider, I have never yet been able satisfactorily to connect 
them together. ‘T’he cocoons are covered over, very soon after 
they are made and the eggs deposited in them, with a coating 
of clay, which effectually destroys all their form and beauty. 
This coating of clay answers probably two ends: —first, the con- 
cealment of the cocoon and its protection from insect enemies ; 
and, secondly, the protection of the eggs from the too powerful 
rays of the sun, dry clay being (as is well known) one of the 
best non-conductors of heat. 
An adult female of A. brunnea was found at Bloxworth, 
Dorset, on the 2nd of June, 1876, and an adult male was 
received, in November 1877, from Mr. C. W. Dale, by whom 
it was found a short time previously at Glanville’s Wootton, 
Dorset. 
A. W. M. Van Hasselt, in a long paper upon the little 
pear-shaped cocoons referred to (Tijdschr. Ent. xix. pp. 28-42, 
pl. i. 1876), comes to the conclusion that there are certainly two, 
if not more, species of Agraca by which they are con- 
structed ; the cocoons differing perhaps in size, and the external 
coating of clay being possibly of specific importance.

On the 22nd of June, 1877, I met with this hitherto very 
rare spider in abundance among the coarse star-grass on the 
sand-hills close to the sea at Studland, Dorsetshire. Both 
sexes were present; but none had quite attained maturity.

Adults of both sexes were found under old casks and among 
logs of wood in a fuel-house at Bloxworth in December 1876. 
Up to that time I had met with this spider but rarely, and 
always out of doors. I have more lately received it from Mr.
