DB. JOHNSTON ON THE ACARIDES OF BERWICKSHIRE. 863 



over the lesser inner one : Palpi twice as long as the rostrum, 

 very bristly, bulged in the middle and sharp-pointed, 4-joint- 

 ed ; 1 St joint small, 2d and 3d large and coalite, 4th small, 

 with a single rather long slightly curved claw, and suspended 

 at its base an ovate bristly appendage : Eyes situated at the 

 base of the rostrum, one on each side and very distinct, some- 

 what pedunculated, dark brown, glistening : Legs 8, filiform, 

 very bristly, the anterior very distant from the posterior pairs, 

 the first pair stoutest and longest and nearly as long as the 

 body ; the fourth next in length, and then the second and 

 third, which are about equal, 7-jointed ; the 1st joint small, 

 the others becoming successively longer, the tarsal the longest 

 and elliptical and armed with two curved sharp claws mov- 

 ing in the same direction, the articulations constricted and 

 pellucid : Bristles of the body short and equal and so thickly 

 set as to constitute a hirsute covering; they arise from a bul- 

 bous root, are a little curved, sharp, and simple, or without 

 any barbs or spinules: those of the members are similar but 

 the bulbous base is not so obvious ; they are sub-appressed, 

 point downwards, and are about the length of the diameter 

 of the joints. 



I am indebted for specimens of this pretty species to Mr. 

 James Hardy. It occurs at the roots of grass and amongst 

 moss in woods. In form it resembles Tr. holosericeum, but 

 is less brilliant (and only a little less) in colouring, and is not 

 half the size. It is tolerably quick in its walk. , 



Hermann says, — " Les poils des pieds sont barbus lat^rale- 

 ment, comme dans les Trombides soyeux et fuligineux ; mais 

 ces poils lat^raux sont beaucoup plus courts que ceux du corps 

 des autres espbces ou il en a ddjk ^'t^ question." I have 

 not noted this character, perhaps from using too low a mag- 

 nifier.
