KiiW — A Synopsis of the Palse-tScorpions of Britain and Ireland. 49 



along basal half; coxae. IV. with posterior margin nearly straight, twice as 

 long as inner ; legs IV. tarsus with tactile hair near extremity; claws with a 

 tooth. L. 3-2. 



$ Abdominal sternites more developed, that of somite IV. strong ; 

 cephalothorax with bristle-tubercles a little more marked ; anterior 

 abdominal tergites strengthened, I.-III. almost without median division, 

 resembling those of thorax ; posterior thoracic tergite and anterior abdominal 

 tergites with strong lateral keels produced posteriorly into a stout spine- 

 like tubercle, and below with margin deflected perpendiculaiiy ; these features 

 strongly marked as far as abdominal tergite V. or VI. thence decreasing 

 towards IX. or X. ; galea smaller ; palps with hand slightly smaller, fingers 

 closing with wider gape ; coxae IV. with stout anterio-dorsal tubercle, 

 posterior margin strongly concave, four times as long as inner ; legs I. with 

 tarsus a little strengthened, its claws slightly enlarged, posterior claw of 

 peculiar shape with strong basal part and with slender distal part running off 

 at an angle, at extremity of basal part a sharp tooth. 



In old buildings, coin-stores, bakeries, stables, lofts, etc. ; lung established, but doubtfully 

 indigenous : London and "Westminster, Maucbester, Glasgow, Edmonton, Grays, Polegate ; 

 Limerick.

III. Withius sub-gen. nov. 



Legs I. with articulation between trochantin and femur rather narrow 

 almost perpendicular ; fingers of palps without accessory teeth ; $ without 

 coxal sac, genital- area simple, with plate II. generally a little longer than 

 plate I., without ram's-horn organs. Eyes 2 (in Britannic species). 



(Britannic species 1 : abdomen with tergites all divided, I. and XI, some- 

 times incompletely; main tergites generally with 6 bristles in front of the 

 posterior marginal row ; palps of distinctive shape, elongated iw $ ; $ with 

 genital-area inconspicuous, with secondary characters including remarkable 

 bristle-areas of sternites well-marked, and with coxae IV. nearly straight 

 posteriorly, but little modified.)' 



C. subruber Sim. 

 C. sulrvher Sim. 1879 (27). 

 2 Palps clear reddish-brown, cephalothorax reddish horny-brown, ab- 

 dominal tergites horny-brown with darker scar-spots and paler bristle- 



' Sub-gen. WUhius (of wbiuh our species is the type) is widely distributed and has many species, 

 mostly distinguishable at a glance by their general appearance; sternal bristle-areas in S , though 

 subject to modification, are probably common to all ; elongation of the palp of the J is also gpiieiiil, 

 and may, e.g. iu G. limyichelifer Balz., be strikingly marked. Of. AVith (66, 8 2).
