^ some South- American Aviculariiclae. 91 



b. Femur of first leg with plumose hairs iuternally, 

 of the third leg noticeably swollen ; protarsus 

 and tibia of first straight; spine of palpal 

 organ serrulate along its convex side cautus. Auss. 



Genus Pamphobeteus, Pocock. 

 Pamphobeteus, Pocock, Ann. & Mag. Nat. Hist. (7) viii. p. 545 (1901). 



Pamplioheteus aniinous, sp. n. 



Colour blackisli, the integument thickly covered with sliort 

 olive-black hairs, showing a characteristic tufted or woolly 

 appearance; upperside of femora of legs with bright steel- 

 blue lustre ; some long foxy-red bristles on the abdomen and 

 legs. 



Tibial spurs and protarsus of first leg practically as in 

 P. ni gr {color ; palpal organ differing from that of the pre- 

 viously recorded species in having the spine broad and spatu- 

 late and oval in its distal half, wliere it is broader than at the 

 base, the median crest resembling that of P. nigricolor. 



Measurements in raillimetres. — Total length 50 ; carapace 

 29 ; first leg 92, second leg 88, third leg 85, fourth leg 104 ; 

 patella + tibia of first 30, of fourth 32 ; protarsus of fii'st 21, 

 of fourth 30 ; femur of first 26, of fourth 27. 



Loc. Madre de Dios, in Bolivia. 



This species is possibly based upon the unknown male of 

 the species from Bogota, described by Ausserer as Lasiodora 

 ferox, which also has a woolly clothing. The Museum 

 possesses larger specimens than the type, but unlocalized. 

 One of these gives the following measurements : — Total length 

 65 millim. ; carapace 33; first leg 98, fourth leg 110. 



Pam-pJioheteus insignis, sp. n. 



<? . — Closely allied to P. nigricolor. Prevailing colour of 

 the hairy clothing a deep olive-brown, with a beautiful bluish- 

 purple bloom on the upperside of the body and limbs. Dis- 

 tinguishable from P. nigricolor by the form of the palpal 

 organ. In P. nigricolor the spine is lightly convex when 

 viewed from one side; when viewed from its concave aspect 

 it is straight and is bordered by sharp crests which converge 

 to the point ; in the distal half of this area there arises a 

 median crest, which is high, lies obliquely, and has a distinctly 

 convex edge. In P. insignis^ on the other hand, the spine is 

 less curved and the median crest is not confined to the distal 

 end of its subspatulate portion, but runs througliout its 

 length.
