Species 10. — Coeixa Wollastoni, D. & S. 



During 1066 we have seen several examples of a Oorixa which, 

 except in coloration, agree so well with the above species that we con- 

 clude they belong to it, and that our description (Brit. Hem. p. 603) 

 was made from immature specimens. Indeed we had but two, ^ and 

 $ , the latter having so collapsed in drying that it was just recognizable, 

 and useful only in showing the character of the palse in that sex. Our 

 description, therefore, will have to be amended in the following par- 

 ticulars : — 



Colour above, dark brown. Sternum black, scapul(e, pleura, and 

 parapJeurcB yellow, the two former black on the inner side. Legs : 1st 

 pair — thighs yellow, in the i^ a black spot on the inner side at the base ; 

 tibia short, yellowish, in the (^ swollen, constricted at the base, above 

 black ; pales yellow-brown, in the (^ (rarely in the ? ), with a black or, 

 piceous line on the upper edge ; 2nd pair brown ; thighs yellowish on 

 the basal half; tarsi with a dark spot at the apex ; 3rd pair yellowish, 

 tarsi with black cilia, 1st joint posteriorly with a large, black, angular 

 spot on the inner side, beginning rather beyond the middle of the length 

 and widening gradually till, at the end of the joint, it occupies all, or 

 nearly all, the breadth (the cilia being dense and long and covering the 

 spot it may be overlooked) ; 2nd joint clear yellow with black margins. 



Length E lines. 



One specimen from the loch near Kirn, Argyleshire, in May 

 (^Scott), and several from peat pits on the moor at Eannoch, in June 

 {Bi/e and Marshall).
