Mr. R. I. Pocock on the Genus Poecilotheria. 93 



colour of the under surface of the tibia of the palp in P. vittata, 

 this segment being uniformly chocolate-brown in P. formosa 



by the presence in P. formosa and the absence in P. vittata of 

 a dark basal patch on the inner side of the anterior femora, 

 and by the darker colour of the underside of the femora of the 

 third and fourth legs in P. vittata. 



(7) Poecilotheria metallica, sp. n. (PI. VII. fig. 3.) 



Colour of carapace and abdomen much as in the other 

 species, but dark bands on the carapace more widely separated 

 mesially and the pale band on the abdomen much less distinct 

 and traversed by a darker stripe ; upperside of legs and palpi 

 tolerably uniformly coloured and becoming darker towards 

 the extremities, showing faint metallic lustre; tarsi not 

 spotted above ; protarsi with a thin brown stripe ; tibiae with 

 very indistinct lines of yellow spots ; lower side of palpi 

 entirely deep brown, with faint metallic blue lustre ; lower 

 side of anterior legs blackish brown, with strong metallic blue 

 lustre, and a large orange-yellow patch on the under and inner 

 sides of .the base of the tibia; third and fourth legs uniformly 

 coloured below with a similar but smaller tibial spot and 

 much less metallic blue tint ; lower side of abdomen uni- 

 formly chocolate-brown. 



Carapace shorter than patella and tibia of first leg, a little 

 longer than those of second and fourth leg ; patella and tibia 

 of fourth a little longer than of second. 



Measurements in millimetres. — Total length 52 ; length of 

 carapace 23'5, width 20; length of palp 37, of first leg 65, of 

 second 59, of third 52, of fourth 64 (all measured from base 

 of femur) ; patella and tibia of first 25, of second 22, of 

 fourth 23 ; protarsus of fourth 15. 



Loc. Near Gooty, 257 miles from Madras. A single female 

 specimen, taken in the engineer's bungalow on the north-west 

 line of the Madras Railway, and sent to Mr. H. R. P. Carter 

 by Mr. H. C. West, chief engineer. 



This species may be easily recognized by the uniformity 

 of the colouring of both the upper and under sides of the legs 

 and body, by the metallic lustre of the under surface of the 

 legs, and the single orange-yellow patch on the tibiae. 



(8) Poecilotheria ornata, sp. n. 



Colour very like that of P. fasciata ; femora of anterior le^s 

 yellow, with a black basal internal patch as in fasciata, but 

 with the stripe in the distal half of the segment much 

 broader; femora of third and fourth legs whitish below, as in
