arcuated at origin ; B 2 persistent ; petiole of cell M l a little longer 

 than ). 



Abdominal tergites dark brown; segments 2 to 7 with a large 

 yellowish area on the sides beyond the base. Sternites yellow except 

 the base and apex of the segments, which are blackish ; segments 7 

 and 8 largely dark brown; remainder of the hypopygium yellowish. 

 Male hypopygium (Plate IV, fig. 25) simple. Ninth tergite large, the 

 posterior margin notched medially. Ninth sterno-pleurite prominent, 

 elongate, but not so excessively produced as in Longurio, jutting 

 slightly beyond the level of the tergite. Outer pleural appendage an 

 elongate, pale, fleshy lobe clothed with long hairs ; inner pleural 

 appendage more or less chitinised, compressed. Sterno-pleurite 

 profoundly incised on the mid-ventral line, the adjacent margins 

 almost contiguous.

Type in the South African Museum. 



The genus Habromastix is principally Australasian in its distribu- 

 tion, but there are three or four Ethiopian species. The genus is very 

 close to Longurio, and is separated from it chiefly by the elongate male 

 antennae. In this genus, as well as in Longurio, the cell M l of the 

 wings varies from sessile to long-petiolate. 



HABROMASTIX JONESI, sp. n. 



Antennae of the male greatly elongated, approximately as long as 

 the body ; mesouotal praescutum brownish-grey with four dark brown

 with the femora black, the tibiae abruptly light yellow except at the 

 tips. 



Male. Wing 12 mm. 



Female. Length 17-18 mm.; wing 12-3-12'5 mm.; fore leg, femur 

 about 7 mm., tibia 8'5 mm. ; middle leg, femur 7'8 mm., tibia 87mm. 



Head small, the frontal prolongation rather short, yellowish above, 

 dark brown beneath and on the sides ; nasus lacking. Palpi short, 

 dark brown. Antennae of the male greatly elongated, approximately 

 as long as the body ; scape yellow ; first flagellar segment yellow 

 basally, passing into brown ; remaining segments dark brown, yellowish 

 at the sutures ; flagellar segments clothed with a long, pale, erect 

 pubescence ; verticils very short and sparse. Antennae of the female 

 much shorter than those of the male, but still elongate. Head dark
