ARACHNOIDEA.

The preceding three species are all distinguished by the curious 

 thickening of the second pair of legs to which we have above 

 alluded. They have, also, all got more or less of the knobs or 

 projections upon them which often accompany the thickened legs. 

 The last species, which we have called podager, will be easily 

 recognised by the figure. It is fawn coloured, and nearly 2 lines 

 in length. From the mouth being under the projecting body, this 

 may probably be taken as the type of a new section or genus. 



Genus Uropoda {Latr.\ 



The chief character of this genus is the existence of a cord 

 attaching the mite to the beetle on which it is found. The other 

 characters are like those of Gamasus, only slightly modified by 

 the bucklfer-like form of the body, which also entails a shortening 

 of the legs.

Uropoda vegetans.— 11. Magnified sketch of ditto ; 12. Specimens. 



The young naturalist is sure to 

 be puzzled with this species ; when 

 a beetle is infested by it, it seems 

 covered by a multitude of minute 

 fawn-coloured shining convex 

 scales (convex above and flat be- 

 jow) gummed on to various parts 

 of the under side of the beetle^ 

 like tortoises or cocci, allowing 

 none of the parts of the body they 

 cover to be seen. They are not 

 easily detached, and when by 

 washing or scraping they are made to move, they do not fall oif, 

 but still hang on to the place where they were fixed, by a fine 

 thread, which is attached by the one end to the beetle and by 

 the other to the under side of the Uropoda. The older natu-
