George: Lincolnshire Mites. AZ 
pointed curved hairs, which are simple, z.e. not feathered. The 
body is rather lozenge-shaped, with rounded angles, and is 
broad at the shoulders. It is covered with rather short bent 
leaf-like scales, slightly pectinated on the surface, in at least 
some cases. The colour of the mite is dark orange red. The 
skin under the scales is marked out in a rather complex pattern, 
a small portion is shown much enlarged at fig. E, taking one 
of the button like bosses as a centre there radiates from it 
3, 4, or 5 broad bands, sometimes looking almost like the spokes 
of a wheel. Professor Berlese in his Acarus Nuovz, 1905, Table 
XV., fig. Va, gives a similar figure, the mite from which it is 
taken (see fig. V), appears to be very much like S. hardyz, but 
is called by him |S. caelata. I found S. hardyi in 1879, and gave 
an outline figure and some notes in the November number of 
Sczence Gosstp for that year ; it will also be found mentioned by 
Murray in his ‘ Aptera,’ page 140. The palpi and mandibles 
are shown much enlarged in fig. F, these last are seen to be 
lancet shaped, and carry a single barb almost at right angles to 
the blade. The mandibles of all the Rhyncholophide are more 
or less lancet shaped, and formed for piercing, and are mostly, 
if not always, more or less barbed. This is very different from 
the mandibles of the Zrombidid@, which are sickle shaped, and 
fitted for tearing. The mandibles therefore are the great 
structural difference separating these two families. Fig. G 
represents what I take to be the larva of S. hardyi, it is re- 
markable in having three claws to each tarsus, the adult having 
two only. 
The next Genus I have to mention is Smaridia Duges and 
the species, S. ampudligera Berlese. This is a very beautiful 
mite, of a rather brick red colour, and covered all over with 
dark cinnabar coloured scales, thickly planted all over the body, 
and also covering the legs, which are paler in colour than the 
body of the mite. The shape of the creature is well shown 
in Mr. Soar’s drawing, fig. H. The eyes of the mite are not 
drawn ; even in life they are difficult to see, being covered with 
the scales ; but in a balsam mount made long ago, all colour 
has disappeared, and the eyes can not be made out. They are 
placed on the cephalothorax between the first and second pair 
of legs, there is also a line or furrow down the middle of the 
thorax, called the dorsal groove or furrow, not seen in the 
balsam mount, but well enough marked in the living creature ; 
and in this dorsal furrow there is a rod of chitin, enlarged 
almost like a battledore at either end, and having two very fine,
