distinguished as follows : — 



1(2). Wings with the fore half yellow and adorned with some eye-like spots ; very 

 small species of 2 '5 mm. in length . . . . . . oculatum, Hend.

3(8). Legs yellow ; wings with very numerous and very small, pale dots. 



4(5). Apex of the wings with a broad black border, which is devoid of hyaline- 

 spots . . . . . . . . . . . . . . . . frauenfeldi, Schin. 



5(4). Apex of the wings with a hyaline spot. 



6(7). Stigma immaculate ; no black spots on the disc of wings . . bipunctatum, Loew. 



7(6). Stigma with 2 hyaline spots near the costa ; on the disc of wings there are- 

 some spots of a deep black colour . . . . millepunctatum, sp. nov. 



8(3). Legs black, with white rings at knees, on tibiae and on hind tarsi ; wings with.

2. Eutretosoma frauenfeldi, Schiner, Novara Dipt., p. 276, pi. iii, fig. 4 (1868). 

 Described as an Icaria from the Cape, and not recorded subsequently ; it may be- 



distinguished by the black border of the wings. 



3. Eutretosoma bipunctatum, Loew, Berl. Ent. Zeits., v, 1861, p. 280, pi. ii, fig. 15. 

 Recognisable by the broad hyaline spot at the apex of the wings, between the- 



ends of 3rd and 4th longitudinal veins. Described as a Trypeta from the Cape and. 

 not recorded subsequently. 



4. Eutretosoma millepunctatum, sp. nov. 



Easily recognised by the white marginal and black discoidal spots of the wings. 



$. Length of the body, 4 mm. ; of the ovipositor, 1 "2 mm. ; of the wing, 4 mm. 

 Head entirely yellowish ; occiput with 4 blackish spots, 2 in the middle above the- 

 neck, and one on each side of the upper border of the rather distinct lateral swellings ;

 velvety black streak in front on each side of the root of the antennae ; lunula broad ;

 black spicules ; 3rd joint as long as the 2nd, rounded at tip, with a narrow dark 

 basal border ; arista with short but distinct pubescence. All the cephalic bristles- 

 aTe of a pale yellowish colour, but the occipital row is formed by numerous short,, 

 thick, black bristles and among them some (3-4) yellow ones ; or. 2 + 3 ; oc. stout.
