“CoLIAS EDUSA” IN ARRAN. 
A MALE specimen of this butterfly was captured by me on 
clover, at Lochranza, in the last week of September 1892, 
and was exhibited by me before the Society.

Nestinc HABITS OF A SPIDER. 
AN interesting, and quite common, little spider is Theridion 
lineatum. Two specimens of this pretty species have come 
under my notice when they have heen engaged in attaching 
the cocoons of eggs to a leaf-shelter. On both occasions I 
kept the spiders for several weeks, where I could, nearly 
every day for at least a few moments, observe the actions 
of the spider and the state of the cocoon. 
The first individual I found on a bunch of sweet-peas in 
a vase. She was then carrying the cocoon attached to her 
body, and evidently seeking a mooring-place suited to her 
purpose. There being no foliage in the bouquet, and the 
flowers fading daily, the spider wandered from blossom to 
blossom for a few days in evident distress and perplexity. 
She was then placed in a small box with a glass lid, where 
she could be conveniently observed. In a few hours she 
fixed on a corner of the box which seemed to meet her 
requirements. There she slung the cocoon securely, with 
many threads stretching in all directions, and took up a 
watchful position above it. No shaking or opening of the 
box frightened her from her post, and though small flies 
were introduced, she made no effort to capture them—but 
they may have been too large. 
In the course of a week or more, the cocoon | began to 
alter from its pale bluish-green to a lighter tint, and to 
expand very gradually; finally the spider family emerged. 
But what appears to be the most remarkable arrangement 
is, that the day before they emerged the mother withdrew 
a little distance from the nest, and there died. Not having
