 apex; corium with irregular transverse wavy markings.

6. concinna, Fieb. Fig. Fieb. Spec. Coris. pi. ii. fig. 9 



(palffi). 



Very like the above, but with the markings of the 

 thorax rather more regular, and those of the clavus rather 

 less regular. Dorsal line of the thorax indicated by a 

 slight tubercle in front. The most conspicuous character 

 is *the small spot on the hind tarsus, which only just fills 

 the inner apical angle of the 1st joint, and the inner basal 

 angle of the 2nd. The palai also are much longer than 

 in pr(BUsta. 



Length 3 lines. 



Lewisham, Lee and Esher. 



7. cognata, Dougl. & Scott. 



Very like the preceding, btit differs from it in not 

 having any indication of a tubercle on the anterior mar- 

 gin of the thorax ; it is also, if anything, rather smaller 

 and of a yellower colour, and has the spots on the hind 

 tarsi more pronounced and not extending on to the 2nd 

 joint. The palffi in the S are also very different. 



Length 2f — 3 lines. 



Scotland ; Loch Grienan and Loch Leven. 



8. sodalis, Dougl. & Scott. 



Like the two preceding, but distinguishable _ by the 

 shorter claws of the intermediate legs, which are distinctly 

 shorter than the tarsi. 



Length 3 lines.
