Mr. C. G. Lamb on Exotic Cliloropidse. 41 



a little distance on the disc, each side of this another whicli 

 runs to the outer angles of the scutellum, diverging as they 

 go ; beyond these the orange is very slightly suffused with 

 grey ; calli shiny orange, pleura the same. Scutellum 

 blackened orange, slightly punctate. 



Wings yellowish^ with orange veins ; small cross-vein 

 just perceptibly beyond the costal ending of the 1st ; hind 

 one about 3 times its length from the torraer, and \^ith its 

 distance iVom the lower end to the 5th vein-ending about 

 1^ times the distance apart of the cross-veins. 



Halteres quite white, with yellowish stalks. 



Legs entirely yellowy Avith no darkening at all. 



Abdomen all darkened orange, with very narrow palish 

 hind margins. 



Size nearly 3 mm. 



Cam. Coll., Mozambique (F. M.). 



Steleocerus latiseta, sp. n. 



There is a single specimen of a very distinct species. 



Head (top view) : — Frons dull orange, lighter over an- 

 tennae, the triangle is remarkable in form ; basally it just 

 does not touch the eyes ; the margins are formed by raised 

 straight ridges; about halfway a sudden diminution in 

 breadth occurs, so that the side boundaries at that point are 

 suddenly shifted inwards ; the space between these forward 

 parts of the ridges is necessarily a little depressed, but down 

 the centre runs a very fine raised ridge, which goes to the 

 front of the head to just behind where the side-ridges meet 

 in a slightly rounded curve ; the whole is shining bluish 

 black except the extreme tip, over which the frontal orange 

 runs; ocelli bright chestnut. Back of head entirely black. 

 Side-view: — Eyes very large, only leaving very narrow lower 

 and fairly narrow hind orange jowls ; the orange frons is 

 just visible, the 3rd is orbicular and all orange ; the arista 

 is a little broader than usual and tapers to a fine point. 



Thorax : dorsum dullish black, })ollinated more and more 

 strongly Mith brown pollen towards the scutellum ; the pre- 

 scutellar depression is present, but is not sharply demarcated 

 from the rest. Scutellum as thorax, w itli divergent bristles, 

 'llie calli and an area below all orange, the pleura shining 

 dark brown, with a few lighter areas interspersed. 



AVings clear, with brown veins, but with a faint smoky 

 cloud between 3 and 4 extending nearly to level of costal 

 ending of 2 ; the second vein long, as in lepidopus. 



Ilalteics witli white knobs.
