specimens, and find considerable diversity in the colour, but after 

 a little practice there is no difficulty in their identification. The 

 web is of considerable size, and consists of an irregular network 

 of fine lines, usually horizontal. Not uncommonly it is placed 

 close beside the snare of the house spider {Tegenaria Derhamii, 

 Scop.), and each insect seems to respect the prey which falls on 

 the other's web, but I have noticed on more than one occasion 

 that when Linyphia nehulosa trespassed on the web of its larger 

 neighbour, it was promptly seized and devoured. 



The other spiders I exhibit, although not new to Scotland, 

 are yet of interest. 



Chiraccmthmm carnifex, C. Koch, I found in abundance on 

 Craigmaddie Moor last autumn. The cocoons were of consider- 

 able size, and being of white silk, and fastened to the tops of 

 the ling heather (Calluna vulgaris) y they could be seen from a 

 considerable distance; and at one place the moor was dotted 

 all over with them, looking not unlike the heads of the cotton 

 grass {Eriophorum), I had previously noticed the same appear- 

 ance in Glen Rosa, Arran; but then it was the cocoons of Epeira 

 cornuta, Clerck, which were attached to the rushes. In Arran I 

 also got a specimen of Chiracanthium nutr'ix, West., and found a 

 few females of Drassus lapidicolens, Walck., by the side of the road 

 from Brodick to Lamlash : these latter were under stones beside 

 their large lenticular egg-bags. 



Under the name of Fhilodromus lineatipes, Cam., a new species 

 was described in the "Annals and Magazine of Natural History" 

 for February last. This description was made from an immature 

 specimen in the possession of Mr Cambridge ; but. in a small 

 collection of spiders made for me in Perthshire by Mr J. J. King, 

 I found several adult females of this species ; and it will conse- 

 quently require to be figured and described anew from the adult 

 specimen. 



VIII. — Oil the larvae of the TenthrecUnidae, with special reference to 

 Protective Resemblance. By Mr P. Cameron. 



In this paper the author discussed the question of the colours 

 of Caterpillars, with special reference to protective resemblance. 

 Protective resemblance, he pointed out, was of three kinds. In 

 one case the larvae were protected by the resemblance of their
