26. Nesostethus niger, sp. n. (Text-fig. 11). 



Colour. — Entirely black except for abdomen which is orange-red with an 

 obscure median dorsal stripe, and some obscure ventral lateral markings brown. 

 Inner margins of acetabulae, posterior and lateral margins of metapleura and 

 rim of metasternal orifice, blackish-brown. Head, rostrum, antennae, and legs 

 shining, the head intensely so, with a faint bluish sheen ; ocelli reddish-brown. 

 Pubescence sparse and extremely short, giving a glabrous effect, except on the 

 two apical antennal joints, apices of tibiae, and the tarsi where pubescence is 

 longer, more dense and paler. Pronotum, scutellum and hemielytra dull black. 



Structure. — Head almost as long as broad across the eyes (45 : 48) ; 

 eyes rather prominent, ocelli about three times as far from one another as from 

 the eyes ; first antennal segment extending about half its length beyond the 

 apex of head, relative length of segments 27 : 70 : 50 : 65 ; rostrum extending 

 to posterior coxae, relative length of segments 30 : 34 : 25 : 25 ; bucculae feebly 

 elevated. Pronotum rather elongate, length is to posterior width as 55 : 75, 

 strongly narrowed anteriorly, anterior width is to posterior width as 42 : 75 ; 

 lateral margins practically straight, anterior margin strongly emarginate ; 

 anterior disc around scars sparsely, very obscurely punctate. Scutellum 

 equilateral, with a T-shaped ridge. Hemielytra not reaching apex of abdomen ; 

 veins very prominent. Posterior margin of metapleuron straight, perpendicular 

 to the lateral margin. Legs comparatively long, the femora unarmed almost as 

 long as the tibiae, the tarsi long. Disc of venter sparsely covered with rather 

 long very line hairs becoming shorter and denser over genital plates.
