W-fuscum, Enderlein, Zool. Jahrb., xxxi, 1911, p. 425. 

 A very distinct species owing to the broad hyaline spot before the end of the 

 submarginal cell (PI. iv, fig. 5). Described from Erythraea, Keren ; and if I have 

 well interpreted the short description of Dr. Enderlein, Trypeta W-fuscum, likewise 

 described from Erythraea, is the same species. There are in the collection two 

 specimens from the Sudan, Khartoum, 29.x. 1910 (H. H. King). 



4. Tephrella tephronota, Bezzi, Bull. Soc. Ent. Ital, xxxix (1907), 1908, p. 154. 

 A species which is easily distinguished by its wing pattern. 



Described from Erythraea, Adi Caie, and not found subsequently. 



5. Tephrella rufiventris, sp. nov. 



This species is very distinct from all the others here recorded on account of its 

 red (not black) abdomen and of its 4 (not 3) hyaline indentations or spots on the hind 

 border of the wings. 



$. Length of the body, 4 - 5 mm. ; of the ovipositor, 0'8 mm. ; of the wing, 4 mm. 

 Head entirely yellowish, but the occiput with a broad, blackish, grey-dusted spot 

 in the middle ; frons narrow, not broader than the eye, entirely opaque and devoid 

 of dark markings, even the ocellar area not being infuscated ; face short, cheeks 

 linear, jowls narrow and without any spot. Antennae entirely yellow, as long as 

 the face ; third joint rounded at the tip ; arista microscopically pubescent. 

 Proboscis and palpi pale yellowish, the latter with yellowish hairs. Cephalic 

 bristles dark yellow, only the oc. and the upper or. being infuscated or even 

 blackish. Thorax black, with only the humeral calli reddish, but it is densely 

 clothed with brassy dust, being however rather shining ; on the pleurae the dust 

 is of a more grey colour ; the short pubescence of the back is yellow ; the bristles

are dark yellowish or more or less infuscated ; the dc. are placed a little before the 

 line of the a. sa. Scutellum flat, triangular, its dust being a little more faint than 

 that of the thorax ; there is a little yellow pubescence on the disc and 4 long 

 marginal bristles, blackish in colour, those of the middle pair being decussate at 

 the tip and only a little thinner than the basal ones. Post -scutellum and meso- 

 phragma shining black, with grey dust. Halteres pale yellowish. Abdomen 

 entirely red, even on the venter, shining, with short yellow pubescence and with 

 dark yellowish bristles at end ; ovipositor shining black, but with the apical 

 segment reddish, and if exserted measuring 1"5 mm. in length. Legs and coxae 

 entirely reddish yellow ; front femora with 1-2 stout and dark yellowish bristles 

 beneath ; hind tibiae with no distinct postical row. Wings with strong costal
