from side of Table Mountain, near Kondebosch (F. Treleaven], 1 ? 

 from Wynberg (F. Purcell) ; also two dried females ; all these speci- 

 mens from the Cape Peninsula. 



II. The VINCTA Group. 



Dentition of tlie upper jaw very dissimilar in the two sexes ; the 

 teeth of the distal or single series not exceeding five in number and 

 separated into (jroups hi/ one or two long untoothcd infer cats in I lie 

 adult male (the distal ijroup often obsolete) (figs. 23-27) ; teeth in 

 the 5 as in Group. I. 



In the first abdominal sternite the posterior median angles of the 

 halves are more or less produced into a rounded lobe in the adult ? . 

 Metatarsus of palps as in Group I. In the $ the upper margin of 

 the basal enlargement of the flagellum is strongly elevated, forming 

 a high, thin, upright keel along its whole length, and the terminal 

 fang of the upper jaw has the inner edge of the upper surface dis- 

 tinctly elevated keel-like to form a groove for the reception of the 

 procurrent portion of the flagellum. When the bend of the flagellum 

 is remote from the apex of the fang, the distal part of this keel lies 

 free and is very distinct ; if, however, the flagellum almost reaches 

 the apex it fills up almost the entire groove, leaving only the anterior 

 angular extremity of the keel free. (In lateralis, Koch, this keel is 

 obsolete.) Palps exceeding or equalling the III. leg in length. 

 Posterior legs with the hairs either as in Group I., or arranged in a 

 mane, or the long ones very numerous. 



All the species of which the habits are known to me are diurnal 

 (lateralis, vincta, spectralis, and others). 



The females of this group may generally be recognised from those 

 of Group I. by the colouration of the abdomen (the hairs on the sides 

 being white or yellow, and nearly always strongly contrasting with 

 the dark hairs on the posterior dorsal plates), and often also by the 

 presence of a mane of long or short hairs on the hind legs. The 

 adult ? is further easily recognisable by the produced hind angles of 

 the first abdominal segment a character not met with in immature 

 specimens nor in any species not included in this group, as far as 

 at present known. 



The species which belong here are : vincta, Koch, villosa, n. sp., 

 spectralis, n. sp., lateralis, Koch, cultrata, n. sp. ; also the following, 

 which are unknown tome: mar shall i, Poc., derbiana, Poc., prodnctn, 

 Karsch, &c.
