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



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

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

 go ; beyond these the orange is very slightly suflused 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 former, and with its 

 distance from 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 yellow, with no darkening at all. 



Abdomen all darkened orange, with very narrow palish 

 hind margins. 



Size nearly 3 mm. 



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



Sleleocerus latiseta, sp. n. 



There is a single specimen of a very distinct species. 



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

 teunse, 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, pollinated more and more 

 strongly with brown pollen towards the scutellum ; the pre- 

 scuteilar depression is present, but is not sharply demarcated 

 from the rest. Scutellum as thorax, with divergent bristles. 

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

 dark brown, with a few lighter areas interspersed. 



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

 cloud betw-een 3 and 4 extending nearly to level of costal 

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



Halteres with white knobs.
