494 On some new African Theraphosoid Spiders. 



twice as long as the carapace, fourth more than twice and 

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

 tarsus and one fourth of the protarsus of the latter j 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 three times as long as 

 high {\Q\ : 6) ; patella rather more than twice as long as 

 high (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. 



Measurements 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 31*5. 



Log. Kinani, British East Africa. 



A single female specimen, collected and presented, together 

 with a male of Phoneyusa Bottom', Pocock, by Mr. Kichard 

 Crawshay. 



The distinctive features of the undoubted genera of Eumeno- 

 phoringe, a subfamily of Theraphosidee 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. S. 1897, p. 772, and figured in the ' Zoologist,' 1898, 

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



a. Scopula on fourth protarsus extending almost to 



base of segment. 



a 1 . Fovea of carapace large and wide Loxomphalia. 



b 1 . Fovea of carapace small, crescentic Hysterocrates. 



b. Scopula on fourth protarsus confined to distal third 



of segment. 

 a 2 . Tarsal scopula of fourth leg divided by a broad 



band of setae Eummophorus. 



P. Tarsal scopula of fourth leg undivided. 



a 3 . Labium very long, conical, half the length of 

 the sternum ; fourth leg much thicker than 



first Citharischius. 



b 3 . Labium less than half the length of sternum; 

 fourth leg not thicker than first. 

 a 4 . Anterior tibia of male with spine-tipped 



spur Monocentropus. 



b 4 . Anterior tibia of male unarmed. 



a 5 . Fovea large, straight .... Anoploscelus. 



b\ Fovea small, crescentically procurved . . Phoneyusa.
