South African Arachnida. 173 



schlechteri Pure, but the upper surface of the tail (and presumably 

 of the first segment also) is said to be deeply grooved longitudinally. 



P. flaviclus, Pocock (Ann. Mag. N. H. (7) v. 3, p. 419, 1899). From 

 Tangs (Taungs ?), Bechuanaland, and apparently closely related to 

 raudus and schlechteri. 



P. ohscurus &nd 2Mchysoba, Penther (Ann. Naturh. Hofmus. Wien., 

 V. 15, pp. 154 and 155, 1900). These two forms do not apparently 

 differ from transvaalicus Pure, as far as can be ascertained from 

 Penther' s descriptions, except in having a relatively shorter and 

 stouter tail.

Lychas pegleei, n. sp. 



(^ 2 . Colour. — Trunk blackish-brown to dark olive-green, varie- 

 gated with yellow markings, the under surface, except posteriorly, 

 pale ; the first 6 abdominal tergites either almost entirely darkened 

 or with the following principal yellow markings : — A median stripe, 

 a longitudinal stripe near each lateral margm, an anterior transverse 

 stripe joining these, a pair of >< marks, a pair of anterior oval spots 

 (one on each side of the median line), a pair of short, transverse, 

 lunate lines just behind the oval spots, besides a few other tiny dots 

 scattered about ; cephalothorax with the yellow markings very similar 

 to those in L. burdoi (Sim.), the principal being a large spot behind 

 each group of lateral eyes, a pair of curved lines closely embracing 

 the dark olive-green median tubercle as in brackets, alongside these a 

 pair of more lateral longitudinal lines converging posteriorly, 3 pairs 

 of short obliquely transverse lines following in succession behind the 

 median tubercle, the anteriormost running from the hind ends of the 

 bracket-shaped marks outwards and forwards, the middle pair parallel 

 to the anterior, but the posterior pair more transverse or even directed 

 slightly backwards ; on each side are also 2 large oblique stripes, and 

 near the posterior margin is a broad two-horned area ; near each lateral 

 margin and often along the middle line is a narrow longitudinal stripe 

 and at each anterior outer corner is a small V • Tail with an equal 

 extent of yellow and infuscate markings or the latter predominating ; 

 segment 5 very slightly darker posteriorly than the other segments ; 

 vesicle infuscate, with yellow dots and stripes. Femur and tibia of 

 pedipalps for the most part infuscate above, with yellow markings ; 

 the hand yellow, with infuscate longitudinal stripes and some veins, 



* According to Pocock (P.Z.S., 1899, p. 834), this name should be substituted 

 for Archisometrus Krphi.
