Lincolnshire, Mr. Halbert and Dr. Freeman report 

 iheni from Ireland, and Mr. Taverner from Scotland. 

 This mite is not nearly so common as Ltiniiesia 

 histrioiiica. 



III. — IJniiusia iiii(/iilaln Miillcr, 17S1. 

 Fem.m.k. — Body : Similar in form to the precedini; 



Fig. S. — Liiitncsia iiudidata, Palpi of Fem.^le. 



species. Length about i -90 mm. Width i '50 mm. 

 Colour : yellow, with black markings. 



Legs. — First pair about 175 mm. Fourth pair 

 about 2*30 mm. Colour a slaty blue. 



Ei'iMERA. — Fig. 9 again shows a difterence in 

 structure to the preceding ones. The first pair are 

 wider apart, with less curve. In colour they are like 

 the legs, and are a slaty blue. 



Pa-U'j. — (Fig. 8.) About l*lo mm. in length, and 

 possess very litlle-diflerence from fig. 3, excepting that 

 the hairs on the last ^segment "but -9«e,-are set further 

 down the inner edge. 



Figf. 9. — Liiitncsia itnditlata, 



EPIMERA AND GENITAL ARE-\ OF FeMALE. 



Genit.^i, Pl.-vtes. — (Fig. 9.) These are also very 

 distinct from those shown in figs. 2 and 5. In this 

 case the discs are arranged three in each plate as 

 before ; but two are near the posterior margin of each 

 plate, and one on each plate near the epimera. 



Localities.- -This is not a common mite. I have 

 found it on the Norfolk Broads, and Dr. George has 

 sent it to me from Lincolnshire. 



IV. — Liinnesia longipalpis Koch. 



Female. — Body : Oval in form. Length about 

 1.20 mm. Breadth about 1.5 mm. Colour red. 

 One variety is all yellow in colour, with brown mark- 

 ings on the dorsal surface. 



Legs. — First pair about i.io mm. Second pair 

 about 2.0 mm. Similar in structure to the others of 

 this genus pre\iously mentioned. The red variety has 

 pale blue legs. The yellow form has yellow legs. 



Pali>i. — It is here we see the distinctive difference' 

 as their length is equal to the first pair of legs, viz., 

 I.IO mm. (fig. 10). I have found one with the palpi 

 still a little longer. 



Dorsal Si-rface. 



I do not think further description necessary for this 

 mite, as the size of the palpi prevents it being mis- 

 taken for any other species of this genus. 



Localities. — North Wales. 



\ . — Liinnesia kocnihei, Piersig, 1894. 



Female. — Body : Oval in form. Length about 

 1.20 mm., width about 1.05 mm. Colour, yellow, 

 with dark brown markings. Eyes, a deep red. 



L^GS. — Fir*t pair -about T.io -mm., -fourth pair 

 about 1.50 mm., veiy similar to the legs of all mem- 

 bers bf this genus. Colour a pale green. 



EriMERA. — Fig. II, differ from those I have drawn 

 in the preceding species. The posterior angles are 

 extended much further back, being almost level with 

 the genital plates. The gieatest point of difference 

 will be noticed in the position of the discs on the inner 

 angle of the two last pair of epimera. They are quite 

 differently situated to those discs on figs. 2, 5 and 9. 

 The colour is a pale green, same as the legs.

 Fig. ir. — Epi.MERA. .AND GENITAL PlatES OF Fe>LALE. 



Fig. 12.— Genital Plates of Male. 



Palpi. — Small, being 0.60 mm. in length. The 

 peg on the second segment dift'ers from those on 

 figs. 3, 6, and 8, in being without the shoulder piece ; 

 the peg coming direct from the limb (fig. 13), and 

 being long and slender. 



Genit.\l Area. — Not very different from those 

 before observed in this genus. See figs. 1 1 and 12. 



Localities. — Very common everj'where.
