will apparently come under heading If, being related in all 

 probability to Monocentropus and Anoploscelus, but certainly 

 diiiering in that the legs are without spines, and the protarsal 

 scopula of the 4th leg extends almost to the base of the segment, 

 as in Hysterocrates, near which Mons. Simon places it. There is a 

 single species named rubida, which was obtained inland of Zanzibar. 



Solenothele, Simon (Ann. Soc. Ent. Trance, 1891, p. 297), based 

 upon a female, named decemnotata, from the Upper Congo. Seeing 

 that the length of the specimen is given as only just over 16 mm., 

 there is strong presumptive evidence that it is immature, and 

 therefore no stress is to be laid upon the division of all the tarsal 

 scopulse by bands of setae. Similarly with the colouring from 

 which the specific name is taken, the young of many species of this 

 group, e. g. Avicularia, being spotted on the abdomen. 



The genus is said to differ from Ischnocolus in having the 

 external spinners nearly as long as the abdomen, and the anterior 

 two pairs of legs broader than the posterior and with wider scopulse ; 

 the tibife and protarsi are spined, and the fovea is transverse, A^ery 

 lightly recurved. 



Judging from these characters, the genus would fall under 

 section «' in the table, but should certainly be recognizable from 

 Miascliistopus by its long spinners, widely scopulate 1st legs, <fec. 



Lastly the Madagascar genus Encyocrafes would apparently 

 fall under section 6^, but since the characters of the male are 

 unknown and there is no mention in the original description of 

 the position of the sternal sigilla nor of the armature of the claws, 

 it is hard to say whether it would come under a '' or h'. The tibiae 

 of the , legs, however, are said to be unspined, which would 

 separate tbe genus from both Monocentrojnis and Anoploscelus. 

 Moreover a young specimen of a Theraphosine from Senbendrana 

 (Madagascar) which I identify as an Encyocrates, has the sigilla 

 submarginal and the claws untoothed. 



The three following genera belonging to the Mediterranean area 

 and occurring, at least in the case of Cluetopelma and Isclinocolvs, 

 in the countries of North Africa, do not, so far as is at present, 

 known, spread into the true Etliiopian Region. 



Chcetopelma, Answerer (Yerh. z.-b. Wien, 1871, p. 190), might 

 be introduced into the table under section a*, having the legs richly 

 spinous &c. ; but it certainly differs from Miascliistopus in having 

 the tarsal scopulse of .3rd and 4th leg divided, two tibial spurs on 

 the 1st leg on the male &c. In these respects it resembles Seleno- 

 gyrus, but is quite distinct owing to the form of the thoracic fovea 

 which is broad and transverse. This genus has representatives in 

 Egypt, Syria, and Arabia. 



Cratorhagus, Simon (Act. Soc. Linn. Bord. xliv. p. 330, 1892), 

 with two Mediterranean representatives, namely, concolor and 

 tetramera from Syria (see Simon, Mem. Soc. Liege, (2) v. 1873, 

 p. 31 &c.), is apparently closely related to Chcetopelma, but at least 

 differs in having the tarsal scopulse of the 1st and 2nd legs in the 

 adult as well as of the 3rd and 4th divided by a band of setae.
