494 On some new African TItcraphosoid Spiders. 



twice as long- as the carapace, foiuth more than twice and 

 a half as long ; first leg falling short of fourth by the 

 tarsus and one fourth of the protarsus of the latter ; no spines 

 on legs except at apices of protarsi beneath ; femur of fourth 

 considerably less than three times as long as high (23 : 9) ; 

 tibia about as wide as high, less than tliree times as long as 

 high (I65 : 6) ; patella rather more than twice as long as 

 iiigh (15 : 6^) ; the inner side of the patella, tibia, protarsus, 

 and tarsus pseudoscopulate — that is to say, the hairs are 

 short, erect, close-set, and equal in length like those of a 

 mole's skin ; on the protarsus this peculiar modification of 

 the hairy clothing extends well on to the upper and under- 

 side of the segment. 



JJeasurements in millimetres. — Total length 52 ; length of 

 carapace 33, its width 25 "5 ; length of palpus 47, of first 

 leg 69, of second leg 64, of third leg 63, of fourth leg 85 ; 

 patella and tibia of first 27, of fourth ol'o. 



Loc. Kinani, British East Africa. 



A single female specimen, collected and presented, together 

 with a male of Fhoneyusa Btttoni, Pococli, by Mr. liichard 

 Crawshay. 



The distinctive features of the undoubted genera of Eumeno- 

 phorinse, a subfamily of Thera])liosida3 characterized by the 

 presence of a remarkable stridulating-organ between the basal 

 segments of the palpus and first leg (an organ described in 

 P. Z. 8. 1897, p. 772, and figured in the ' Zoologist,' 1898, 

 pp. 14-21), may be tabulated as below : — 



a, Scopiila on fourth pruttirsus exteuding almost to 



base of segment. 



a^. Fovea of carapace large and wide Lo.vomphalia. 



b^. Fovea of carapace small, crescentic Hysterocrates. 



b. Scopula on fourth protarsus confined to distal third 



of segment. 

 a^. Tarsal scopula uf fourth leg divided by a broad 



band of seta? Euntennphorus. 



b^. Tarsal scopula of fourth leg undivided. 



c'. Labium very long, conical, half the length of 

 the sternum ; fourth leg much thicker than 



tirst L'itharischius. 



b\ Labium less than half the length of sternum ; 

 fourth leg not thicker than tirst. 

 n*. Anterior tibia of male with spine-tipped 



spur Munocentropus. 



b*. Anterior tibia of male unarmed. 



a\ Fovea large, straight .... Anoploscelus. 



6'. Fovea small, crescentically procurved , . Phoneynsa,
