b. Femora of legs whitish or yellow beneath and on 

 the inner side, the first and second pairs, and 

 usually the third and fourth also, with a con- 

 spicuous black stripe on the distal half beneath ; 

 (femora fringed or not). 

 a 2 . Lower side of abdomen with a broad reddish 

 transverse band behind the genital fold ; (femora 

 of palpi and anterior legs fringed ; anterior legs 

 lemon-yellow beneath, with broad black stripes; 

 posterior legs bluish white, with broad stripes ; 



no internal basal spot on anterior femora) regalis, sp. n. 



Ir. Lower side of abdomen a uniform chocolate-brown 

 or black, without a broad reddish band behind 

 the genital fold. 

 a 3 . Tibia of palpus a uniform deep chocolate-brown 

 beneath ; (lower side of legs whitish ; the an- 

 terior femora with inner basal patch and broad 

 distal stripe ; femur of third leg at most 

 weakly banded, of fourth not banded below ; 

 their segments on the anterior legs without 



fringes) formosa, sp. n. 



i 3 . Tibia of palpus pale beneath, with at most traces 



of black patches extending inwards from the 



sides of the segments. 



a 1 . Femora of legs without well-developed 



fringes ; black stripes on the lower side of 



anterior femora narrow, also very narrow on 



femur of third leg, and absent on lower side 



of femur of fourth (with a basal spot on 



inner side of anterior femora ; anterior legs 



lemon-yellow, posterior bluish white) fasciata, Latr. 



I 1 . Femora of legs with well-developed fringes ; 

 black stripes on lower side of femora of all 

 the legs very broad as compared with 

 fasciata. 

 a''. With a distinct black basal spot on inner 

 side of femora of first and second pairs ; 

 black band on inner side of anterior femur 

 only about half the width of the lemon- 

 yellow basal portion ornata, sp. n. 



b 5 . Without a distinct internal basal patch on 

 the anterior femora ; black band on lower 

 side of anterior femur almost as wide as 

 brownish-yellow basal portion of segment, striata, Poc. 



The males may be determined as follows, neglecting for 

 the present certain differences in the structure of the palpal 

 organ, which are easy to detect and figure, but difficult to 

 describe : — 



a. Lower side of femora brown, not banded ; (femora 



of palpi and of first and second legs not fringed 



either externally or at the apex internally) subfusca, Poc. 



b. Lower side of femora of first and second legs yellow 



or white, with a conspicuous black stripe near the 

 distal extremity.
