1882.] REV. O. p. CAMBRIDGE ON NEW ARANEIDEA. 437 



colour is a pale whitish yellow-brown, clothed with fine greyish 

 hairs ; on the upperside is a long, tapering, not very distinct, narrow, 

 blackish longitudinal central stripe ; on each side is a stronger 

 blackish-brown one ; the underside has a broad longitudinal blackish- 

 brown central band, with a narrower stripe or line on each side of it. 



The spinners are short, those of the inferior pair strongest ; and 

 immediately in front of them is the supernumerary spinning-organ 

 characteristic of the family and genus. 



Two examples of this very distinct species were contained among 

 other Spiders found in CafFraria, and kindly given to me by Mr. J. 

 Mansel Weale. 



MlAGRAMMOPES BREVICAUDA, Sp. H. (Plate XXXI. fig. 12 A.) 



Adult female, length 4 lines. 



In its general colouring and appearance this Spider bears close 

 resemblance to M. longicauda ; but the shorter production of the 

 posterior extremity of the abdomen distinguishes it at a glance. 



The legs also are shorter, though preserving the same relative 

 proportions and armature ; and the cephalothorax is uniformly of a 

 deep but dull brown hue, no longitudinal central paler band being 

 discernible. The abdomen of both the examples examined were in 

 bad condition ; but there appeared to be a stronger longitudinal 

 dark central stripe on the fore half of the upperside, and the lateral 

 bands are wanting ; the underside has a longitudinal central 

 yellowish-brown band, margined on each side with a strong, deeper 

 brown line. Spinners short, compact, and in other respects like 

 those of the foregoing species. The interval between the two central 

 eyes appears to be slightly greater than in that species, but other- 

 wise there is not much difference in this part of their structure. 



Two adult examples were received from Caffraria with those of 

 M. longicauda. 



Family Poltid^. 

 WixiA, g. n. (nom. propr.). 



Cephalothorax short, broad, sides deep and convex, lateral mar- 

 ginal constriction slight, profile (to beginning of hinder slope) level. 

 Height of clypeus considerably exceeds half that of the facial space. 

 The caput appears to usurp the larger portion of the cephalo- 

 thorax. 



E^jes rather small, in three widely separated groups, a central 

 one of four forming a small, nearly vertical quadrangle on a slight 

 prominence of the upper part of the anterior extremity of the caput. 

 Each of the other groups, of two nearly contiguous eyes placed 

 horizontally, is situated far below, near the lower fore corner of the 

 caput. 



Legs short, tolerably strong, not greatly different in length, 1, 2, 

 4, 3 ; furnished with spines on the metatarsi, tibiae, and genual 

 joints. The tarsi end with three claws, beneath which are one or 

 more supernumerary opposed pectinated ones. 



Falces long, powerful, conical and vertical.
