and abdomen of the same colour: first pair of legs the longest, then 

 the fourth, second and thh'd : length -j-^ of an inch : females captured 

 in November and December on rails and under stones, near Llanrwst. 

 (Id. 626). 



19. TJieridion alhens. Nearly white, except a small, oblique oval, 

 formed by a fine black line, which occurs near the middle of the up- 

 per part of the abdomen, on each side of the median line : first pair of 

 legs the longest, then the fourth, second and third : length -| of an 

 inch : found in July among strawberry plants at Hendre House, near 

 Llanrwst. (Id. 627). 



20. TJieridion callens. Cephalothorax pale yellowish brown, its 

 lateral margins, a triangular central spot which projects a line to the 

 base of the eyes, and a small triangular spot immediately behind each 

 lateral pair of eyes black : legs long, slender, yellowish brown, with 

 numerous darker bands, first pair longest, then the fourth, second and 

 third : abdomen variegated with black, red and white : length \ of an

" It constructs a very remartable cocoon of a balloon shape, measuring about J of 

 an inch in diameter ; it is composed of soft silk of a slight texture, and a pale brown 

 colour, enclosed in a loose irregular network of strong, dark red-brown silk ; several of 

 the lines composing this network are united near the apex of the cocoon, leaving in- 

 tervals there through which the young spiders pass when they quit it, and, being ag- 

 glutinated together throughout the remainder of their length, form a slender stem, 

 varying from fi to ^ of an inch in length, by which the cocoon is attached to the un- 

 der surface of stones and fragments of rock, appearing by its figure and erect position 

 like a small fungus or some minute production belonging to the vegetable kingdom. 

 The eggs are very large, considering the small size of the spider, five or six in number, 

 spherical, not agglutinated together, and are of a brown colour. I have not been able 

 to procure an adult male of this species, which frequents woods in the west of Den- 

 bighshire."— (Id. 627).

Few tribes of insects are more extensive than the Cm'culionidae, 

 and among these, the Orthoceratous division contains as interesting 

 and curious forms as are to be found among the Coleoptera. All the 

 genera of Brenthidag, Anthribidse and Bruchidse are, in this respect, 

 most singular : while in what the scientific Schoenherr has called the
