Steleocerus nigricornis, sp. ii. 



This species is next to Becker's S. longicollis (II. p. 401), 

 but cliflFers as follows : — 



The halteres are grey, not white; the jowls are larger, 

 about ^ the depth of the third antenual joint ; the tongue is 

 pale, not black ; the antennae are all deep black, not red ; 

 legs a little paler ; wings more normal, with rounded anal 

 angle. 



Size 5^ mm. 



Cam. Coll., Durban {F. M.). 



S. ensifer (?), Thorns. 



A single si)eciraen agrees fairly with Thomson's descrip- 

 tion (Eug. Resa, p. 605), but it is possible that we have 

 another species here. The legs are quite pale ; the frontal 

 triangle is not all yellow, but is very much suffused with 

 shining brown, which does not, however, entirely cover the 

 triangle, but occupies the base and shades off forward. 

 One cannot be sure of the identification from this single 

 specimen. 



Bur. Coll., Mysore. 



There is an immature specimen in Bur. Coll. from Coim- 

 batore, Madras, which is near S.fonnosus, Beck. 



Steleocerus quadrivittatiis, sp. n. 



From the Chirinda Forest, S. Africa, we have a few 

 specimens of a species of the ensifer-ienellus group. 



Head (top view) : — Frons yellow and dull, the triangle 

 equilateral, with nearly straight sides ; basally it practically 

 touches the eyes and extends by a sharp point right to the 

 front ; it is suffused with shining brown, which leaves narrow 

 yellow side-lines and broader boundaries on the hind head, 

 where the black part of the triangle's base extends as a 

 broad stripe down the hind head. Side view : outline fairly 

 circular, the frontal and facial tangent-planes making about 

 90°, and the hind jowls large ; eyes oval, oblique forwards, 

 with narrow lower jowls less than half the width of 3rd ; all 

 the side is whitish yellow. Antennae rather large, the 3rd 

 projecting backwards a little, so as to be a longish oval with 

 axis parallel to body-axis ; it is yellow, but darkened dorsally ; 

 2nd yellow, arista normal. Face, palpi, &c., all pale yellow. 



Though there are but few specimens, the thorax varies 

 somewhat in amount of darkening ; dorsum with a broad
