1897.] MR. U. I. POCOCK ox ETHIOPIAN SPIDERS. 741 



spine beneath and four in front; tibia of 4th with two spines 

 beneath and two in front, protarsus with one apical beneath and 

 about five in front : all the spines intermixed with coarse bristles. 



Measurements in millimetres. Total length 16"5 ; length of cara- 

 pace 8, width 6 ; length of palp 9, of 1st leg 13-5, of 2nd 12-5, of 

 3rd 12-3, of 4th 16. 



Loc, East London {H. A. Spencer). A single female example. 



Apart from the characters pointed out in the generic diagnosis, 

 this new Spider differs from Evhrachycercus in its much shorter 

 legs, the carapace for example being one half instead of one third 

 the length of the 4th leg, and as long as the patella, tibia, and 

 protarsus of the 1st. 



The two may be easily recognized as follows : — 



a. Ocular tubercle close to the anterior border of the 



carapace (not including the membranous edge) ; 



ungual tufts not so thick, not concealing the claws, 



which are distinctiy toothed ; legs relatively long 



and slender, scopulie of anterior pair broad ; all the 



tarsal scopulae divided, the posterior very broadly ; 



protarsi of posterior legs scarc?lj scopulate Euhrachycercus, nov. 



h. Ocular tubercle distinctly removed from the margin ; 



ungual tufts very thick, concealing the claws, which 



are unarmed ; legs short and thick, with narrow 



scopulfe ; protarsal scopula of 3rd and 4th legs ex- 

 tending past the middle of the segment; tarsal 



scopulae only finely divided Brachionopus, nov. 



In addition to Leptopelma the two following genera of the 

 family Barychelidce are found in the Ethiopian Eegiou ; namely, 

 Pisenor and CypJionisia, both described by Simon (Act. Soc. L. 

 Bordeaux, 1889, pp. 409-411); btit according to the diagnoses 

 these genera fall into the section BarycJieleo', in which the ocular 

 area is at least as long as wide. They both further differ from 

 Brachionopus in having the anterior lateral eyes placed upon the 

 anterior edge of the carapace. In some respects Pisenor seems to 

 approach very closely to Eubrachycercus, but the two are certainly 

 geuerically distinct, judging by what is said of the eyes of Pisenor, 

 seeing that the ocular area of Eubrachycercus is transversely oblon"-, 

 and nearly, if not quite, twice as broad as long. 



Cyphonisia differs from Pisenor, according to Simon, in having 

 the ocular area narrower in front than behind, and the thoracic 

 fovea lightly recurved instead of transverse, &c. 



The following species of these genera have been established :— 



Cyphonisia ohesa, Simon, Act. Soc. L. Bordeaux, xlii. 1889, p. 409. 

 Erom the Congo (Eiver Quiliou). 



Pisenor notius, Sim. loc. cit. p. 411. Erom the Zambesi. 



P. nigellus, id. ibid. Erom the Congo (Landana). 



P. hohneli, id. Ann. Soc. Ent. Erance, 1890, p. 125. Erom 

 Kilimanjaro. 



Possibly to the genus Pisenor belongs the species described from 

 Moschi as Idiommata lepida by Gerstaecker (Von der Decken'a 

 ' Reisen in Ost-Afrika,' iii. 2. p. 485).
