shape. Legs entirely pale yellowish ; front femora with 2-3 yellow bristles beneath ; 

 even the spur of the middle tibiae is yellowish ; hind tibiae with no distinct row. 

 Wings elongate, with a distinct costal bristle ; 3rd longitudinal vein bare and 

 perfectly straight ; last portion of the 4th vein distinctly curved at base ; small 

 cross-vein placed after the middle of the discoidal cell ; lower angle of the anal 

 cell acute but not produced. The veins are pale yellowish, but infuscated in the 

 fuscous parts of the wing pattern. The pattern is formed by a diffuse reticulation, 

 which is yellowish brown in colour ; the base is not spotted ; the stigma is quite 

 colourless, with a black basal dot at the insertion of the costal bristle ; in the 

 marginal cell there are 2 perpendicular dark streaks, forming 3 broad hyaline spots ; 

 submarginal, first posterior and second posterior cells, each with 2 rows of ill-defined 

 and broad, rounded hyaline spots, those of the 2nd posterior cell being more numerous 

 in the male than in the female ; discoidal cell with only the apical half darkened 

 and in this with 4 hyaline spots disposed in 2 rows ; 3rd posterior cell with some 

 spots at border ; axillary cell quite hyaline. In the middle of the wing, on the 

 space between the 2 cross-veins, there is a more fuscous patch, which bears in the 

 centre the characteristic elongate spot of a deep black colour, preceded by a rounded 

 hyaline spot near the small cross-vein ; this black spot recalls that which is to be 

 observed in the North American Euaresta bella, Loew, but is more intense. 



Type <J and type $, a single pair of specimens, from Nyasaland, Chiromo, 

 Euo R,, 23. ix. 1916 (R. C. Wood). 



2. Euribia discipulchra, sp. nov. 



Nearly allied to the preceding species, but certainly distinct on account of its 

 smaller size, darker colour and much shorter ovipositor. 



$. Length of the body, 2 mm. ; of the ovipositor, - 3 mm. ; of the wing, 2 mm. 

 Head and its appendages as in the preceding species, but the frontal band is of a 

 darker orange-yellow colour and the antennae are of a darker reddish colour. Thorax 

 and scutellum black, densely grey-dusted ; the scutellum is reddish at end, with 

 the dark dots more distinct. The bristles are as in the preceding. Abdomen entirely 

 black, grey-dusted, with yellow pubescence and with yellow bristles ; ovipositor 

 very short and broad, obtuse, flattened, of a shining reddish colour, with black end. 

 Legs as in the preceding species. Wings likewise ; but the dark pattern is more 

 blackish and better denned. The dark middle patch is broader and more striking ; 

 its central deep black spot has at the 2 ends, on each side, a very sharply defined, 

 whitish hyaline, rounded spot, which contrasts with the black streak, forming a 

 very curious and elegant pattern. 



Type $, a single specimen from Nyasaland, Chiromo, Euo R., 23. ix. 1914 

 (R. C. Wood). 



3. Euribia praetexta, Loew, Berl. Ent. Zeits., v, 1861, p. 286, pi. ii, fig. 19. 



Very different from all the other sjDecies on account of the extensive black pattern 

 of the wings, and thus approaching Euaresta, but without any radiating margino- 

 apical pattern. 



Described from Caffraria and not recorded subsequently.
