144 Christmas Island. 



darker, forceps separated at the base by a space about equalling^ 

 tbeir breadth, gradually tapering, and curved inwards to the tips, 

 which are crossed, and not very acute ; a large tooth on the inner 

 edge at about one-quarter of their length, followed by two or more 

 smaller ones ; tegmina short, obliquely truncated (no wings), and 

 one or two of the following segments of the abdomen marked 

 with blackish at the sides ; pygidium short, broad, transversely 

 oblong ; pliciferous tubercles obsolete. 



Described from two males. An hermaphrodite specimen is paler, 

 and has the tegmen on the left side longer than the other, and 

 subacute, and the right branch of the forceps is considerably shorter 

 and slenderer than the other ; waved, unarmed, and more acute at 

 the extremity. 



The last specimen is from North Coast, March, 1898 ; the others 

 are without special locality. 



5. Labia incerta, sp.n. (PI. XII, Fig. 5.) 



Female. — Eesembles the last species, but the head, pronotum, and 

 tegmina are purplish brown. Abdomen fulvous, with purplish- 

 brown markings at the base and sides. Forceps rather slender,, 

 waved, with the tips pointed and approximating ; the inner edge 

 finely serrated. 



A single specimen. 



6. Labia indistincta, sp.n. (PI. XII, Fig. 4.) 



Male. — Rufo-castaneous, antennae thirteen-jointed, head above,, 

 hinder part of pronotum, and tegmina varied with brownish ;. 

 tegmina rather narrow, subtruncated ; abdomen beneath them,, 

 with a transverse blackish band, but the rest of its upper surface 

 uniformly reddish. Forceps nearly straight, incurved at the tips, 

 and set with long, fine, grey hairs ; the inner edge with a cultrate 

 projection at the base, about twice as broad as the short transverse 

 pygidium, which is rounded off towards the extremity ; beneath 

 this is a quadrangular projection. 



A single specimen obtained. 



Much resembles the two last species. In all these small Labia 

 the pliciferous tubercles on the abdomen are almost, if not quite, 

 obsolete. 



7. Labia (?) subarmata, sp.n. (PI. XII, Fig. 7.) 



Long. corp. cum forcip. circa 5 mm. 



Male. — Dark chestnut-brown, thickly and very finely punctured 

 on the tegmina and abdomen, and covered with a veiy close pile. 

 Head black above, nearly quadrate, but with the hinder angles 

 obtusely rounded off. Antennae eight- jointed (?), pilose, rufo- 

 testaceous, the scape oblong, at least three times as long as broad^
