346 Mr. F. O. P. Cambridge on the 
ance several other species from the sameregions. The figure 
of the vulva and pedipalp should, however, render the identi- 
fication of either sex comparatively easy. 
Ctenus sarawakensis, sp. n., 3. 
(PITY. fig. 32) 
~ Hab. Sarawak, Borneo. 
Types in coll. Brit. Mus. Nat. Hist. (e coll. Hose). 
@... Tot..len, 15°5.mm,, carap. 7 ; legs.1. 21, 11.19; ince 
iv. 24; ant. marg. of carap. 3; pat.+tib, 1. 7°5, ill. 5, iv. 7. 
Qolour similar to that of Hosez. Pubescence of abdomen 
copper-coloured, with traces of dorsal and ventral blotches 
as in the other species. 
_ Structure. Spines and general characters similar to those 
of Thorelli’, Carapace slightly gibbous behind and abruptly 
inclined to base. 
Vulva longer than broad, disk broadly transverse and 
uniformly convex, narrowed before and behind, with a wedge- 
shaped raised carina anteriorly. Margins of disk black and 
coriaceous. On each side of the posterior margin lies a long 
sinuous dentate process, their apex extending distinctly be- 
yond the posterior margin of disk and slightly converging. 
Though scarcely distinguishable in general characters, 
except for their smaller size, from Hoset, Torelli’, and others, 
the form of the vulva furnishes evidence that they are 
distinct from these other forms. 
Three females, taken by Mr. Hose at Sarawak, Borneo. 
Ctenus ceylonensis, sp. n., o ¢.

35; legsi, 21°5, un. 20, 11.18, iv. 24; pat.+tib. 1. 7, 11. 3°93; 
raiante 
$.—Structure. Spines and general characters as in 
Thorellii, Carapace gibbous behind, abruptly inclined to 
base. Eyes: second row straight by centres; ocular quad- 
rangle broader than long, narrower in front; post. centrals 
one half larger than ant. centrals, two thirds a diameter apart, 
distant from lat. ant. half a diameter of the latter; ant. 
eentrals half a diameter apart, one diameter from anterior 
margin of clypeus.
