tudinally ribbed (so also in the other three 

 species), but this may be due to the seriate hairs. 

 The distal segment is a mere flattened cap with a 

 fringe of minute spiny hairs. 



GEORGIA, gen. nov. 



General appearance of a slender £lnemothrombiu)n, 

 but (as in some Sericothrovibid) the dorsal 

 trichomes vary, being more or less setaceous and 

 feathered on the anterior parts of the dorsum, but 

 from the shoulders backward they are lobate or 

 ramose at the apex and plumose below ; always 

 obtuse and opaque. Hairs of the limbs simple, 

 plumose. 



Type : ramosa, Geo. 



9. Georgia ramosa, Geo. 66, 67. 



Ottonia ramosa, Geo. 



Ottonia sheppardii, Geo. 



Microtrombidiiijn i-a?nostim, Halbert. 



Quite a common species in Britain, but not yet 

 recognised abroad. 



Yorkshire, Cheshire, Lancashire, Scotland, Ireland. 

 MICROTHROMBIDIUM, Berl., 1910. 



Agreeing generally with the two foregoing, but 

 differing in the following characters : Abdomen not 

 narrowed behind ; no inflated or spatulate or 

 branched trichomes on either body or limbs ; 

 eyes usually sessile or nearly so ; accessory 

 armature of article iv. of the palp considerably 

 reduced, and article v. more or less bluntly pointed, 

 never distally expanded. 



Type : pusilhiin, Herm. 



I give these characters with some reserve as few 

 species are known to me ; but those which I do 

 know indicate two very distinct groups.
