96 AN EXPEDITION TO MOUNT BATU LAWI. 
Head. lower lip whitish-brown, upper surfaces entirely yel- 
vety-black. 
Prothorax white below, above black with indications of a paler 
mark on either side. 
Thorax white below, above and on the sides velvety black. 
There is an indication of a narrow antehumeral stripe on either 
side, of a dull black purple colour, and of a band of similar colour 
at the base of the side of the thorax. During life it is possible 
that these bands are of a brighter colour. 
Abdomen entirely dull “black (in one specimen there is some 
trace of lighter colour on the dorsal side of segment 10) except for 
the sides and under surface of the first and second segments which 
are brownish-white. 
Legs, anterior surface of femora and tibias white, dorsal 
surfaces black, spines and tarsi black. 
Anal appendages black, very similar in et and proportions 
to those of C. octogesima. Upper pair # as long as lower pair, 
rather stout, finger -shaped, flattened from side to side, with a small 
inwardly and downw ardly directed tooth at about the middle of 
their length on the under side. Lower pair slender cylindrical, 
ending in a sickle-like curve, their extremities turned almost direct- 
ly inwards to meet each other. 
This species rivals in size C. orang Forster from the Malay 
Peninsula, and with it stands as the largest described species of the 
genus. It is further characterized by its very sombre coloration, 
as well as by the shape of the anal appendages. 
Amphicnemis remiger, nu. sp. 16 Kuala Madalam, Limbang 
River, Sarawak. 11.5.11. 
Length of abdomen 34 mm. Length of hind-wing 19 mm. 
Upper lip metallic bronze-green, the whole of the upper sur- 
face of the head greenish-black. 
Prothorax metallic bronze- -green above, pale yellow below. 
The posterior margin of the prothorax is produced on either side 
into a sharply projecting angle, but there is no median spine. 
The thorax is metallic bronze-green above; this colour ends 
sharply immediately beyond the first lateral suture, where it is 
succeeded by the pale primrose yellow of the sides and under sur- 
face. 
The abdomen has (as in other species) the dorsal surface of 
the first two segments of a metallic green colour. The remaining 
segments are dull brown above, paler beneath, the last four seg- 
ments almost uniformly dull brownish black. 
Legs primrose yellow, with a fine black ring at each articula- 
tion. 
Anal appendages white (see fig. 4). Upper pair slender, end- 
ing in a dise so that they have rather a paddle-like shape. The 
shaft a little bowed with a small dorsal tooth at its middle. Lower
