a little longer and moi-e convex, with the suture itself broader. The 

 metasternum is more remotely punctured, and but little depressed. In 

 the male the middle tibiae have at the apex, on the inner side, a very 

 minute spur ; the sixth segment has a slight triangular notch ; the fifth 

 has a wide triangular emargination, and is polished in the middle 

 longitudinally, but very slightly depressed, having on each side an 

 acute, abruptly elevated keel, not reaching to the hinder margin, and 

 also a slight central tubercle ; the remaining segments are slightly 

 depressed in the middle, with long yellow hairs forming curls, as in 

 S. Rogeri. 



Wicken Fen ; also sparingly in the London district from moss, 

 at Wimbledon, Richmond, Shirley, and Croydon. I have a male from 

 "Wimbledon in which the ciliation is entirely absent. 



GrUTNEMEKi, Jocq. Duval, Fairm. et Lab. 2^ lin. Deep shining 

 black, surface very \mequal, in parts " warty"; the basal joint of the 

 palpi, and base of the femora abruptly, bright yellow, the middle of the 

 tibfe pitchy -testaceous, and the clava of the antennae fuscous. Head 

 with a shining middle keel, and two interrupted side elevations. 

 Thorax somewhat suddenly contracted behind the middle, with a coarse, 

 shining, interrupted, dorsal channel rather behind the middle, and a 

 wide and deep transverse depression in front. Elytra very coarsely 

 and closely punctured, roughly and irregularly " engine-turned," the 

 interstices shining, confluent, and elevated unevenly. Abdomen 

 broadly margined, rather coarsely punctured at the base and sides of the 

 segments, the keels obsolete, and the transverse depressions hairy. 

 The metasternum is scarcely, if at all, depressed ; shining, strongly and 

 rather remotely punctui-ed. In the male the sixth and fifth segments 

 are very shallowly (scarcely perceptibly) emarginated. The abdomen 

 is clothed with scanty long pubescence, which gets thicker towards the 

 apex. Judging from the upper side one is led to expect a corresponding 

 increase of development in the sexual characters of this species ; there 

 is, however, scarcely any difference between the male and female in 

 that respect. 



Under stones in and near waterfalls (often with Dianous) ; at 

 Paisley, Buxton, Matlock, and North "Wales. 



PEODiTOE, Erichson. 1| lin. Dull leaden black, rather cylindi'ical; 

 basal joint, and base of the second joint of palpi, testaceous ; the legs 

 pitchy -black or dark pitchy -red, lightest at the base of the femora ; eyes 

 very large and prominent. This species most resembles S. argiis, from 

 which it difters as follows. It is darker in eoloiu' and not so much
