being convex along under side and more densely scopulate, II. also 

 unspined, III. with 1 dorsal spine, IV. with 0-1 spine on inner 

 surface at apex and 2 on outer surface. Metatarsi I. and II. not 

 scopulate, I. slightly concave along both inner and under sides, 

 under surface with 0-1 inner (basal) and 3 outer spines, outer sur- 

 face with 1 inferior apical spine, and inner surface with 1-2 (mesial 

 and basal) spines ; III. and IV. with small apical patch of scopular 

 hairs. Tibia I. as long as the metatarsus, the under side with a 

 double row composed of 5 outer and 4 inner spines, the outer side 

 besides w T ith 1 and the inner side with 5 other spines. 



Abdomen with some long setiform spines at base above. Posterior 

 spinners with the apical segment subequal to or slightly longer than 

 the middle segment, these 2 segments together longer than the basal 

 segment. 



Sternal sagilla as in P. nigriceps (Pure). 



Total length (including chelicera) 12 J mm. ; length of carapace 5 J. 



Gen. SPIROCTENUS, E. Sim." • 

 1. Spiroctenus pallidipes, n. sp. 



Specimens. — 6 $ $ and 18 ? ? , all adults, collected at Touws 

 River Station, Worcester Div., by my wife, Mr. R. M. Lightfoot, and 

 myself in August, 1903. 



Closely allied to S. liglitfooti, (Pure.) (Trans. S. A. Phil. Soc, 

 vol. xi., p. 363), which it resembles in most respects. 



Colour pale yellowish, the chelicera reddish ochraceous, the cara- 

 pace often faintly infuscated, the dorsal surface of the abdomen with 

 a well-defined pattern composed of a series of arcuate, transverse, 

 black or purplish- black stripes united by a median longitudinal 

 stripe, the anterior stripe not expanded into a large patch ; sides of 

 abdomen and under surface without marks, excepting a black spot 

 above and sometimes a smaller one in front of each of the posterior 

 spinners ; legs very pale yellowish, concolorous, the femora not 

 darker than the distal segments. 



$ ? . Carapace as long as or slightly longer than the tibia and 

 J- the metatarsus of fourth leg, but a little shorter than or subequal 

 to the tibia and metatarsus of first leg ; fovea a deep transverse 



* According to Simon Spiroctenus, E. Sim. = Hermacliastes, Poc, and I may add 

 that Bemmeris pardalina, E. Sim. (Bull. Soc. Ent. Fr., 1902, p. 42), is evidently an 

 immature example of Hermachastes collinus, Poc, while Gtenonemus pectinuier, 

 E. Sim. (ibid., p. 43), is also a young Heniiacliastes. Both these genera, therefore, 

 must be added to the synonyms of Siriroctenus.
