There are two specimens ill the collection, a male without exact 

 locality, and Bergroth's specimen (No. 2), a female from Cape Town. 

 The specimens give the following measurements : 



Hale. Length 18*6 mm. ; wing 19'1 mm. 



Female. Length 23'5 mm. ; wing 19'2 mm. ; fore leg of female, 

 femur 8'5 mm. ; tibia 10 mm. ; middle leg, femur 10 mm. ; tibia 

 10'2 mm. ; hind leg, femur 12 mm. ; tibia 14'1 mm. 



The antennae are short, light yellow, the basal enlargement of the 

 ilagellar segments with four black verticils. The wings are shown on 

 Plate XII, fig. 28. Male hypopygium (Plate XIII, fig. 49) with the 

 sclerites of the ninth segment fused into a ring, continuous except on 

 the mid-ventral line of the sternite, where the edges are contiguous 

 and carinate ; pleural suture short, almost straight, slightly upcurved 

 at the end. Ninth tergite (Plate XIV, fig. 58) moderate in size, the 

 caudal margin concave with a very broad median lobe, whose caudal 

 margin is squarely truncated and bifid for a short distance by a deep 

 line ; the caudal dorsal margin with numerous small black spicules ; 

 a shallow semicircular depression at the base of the median lobe. 

 Outer pleural appendage very broad and flat, pale, almost white, the 

 apex somewhat obliquely truncated, the outer face with short, appressed 

 hairs that are most numerous at the cephalic dorsal angle of the lobe ; 

 inner pleural appendage showing through the translucent outer 

 appendage as figured, complex, flattened, the apex produced into 

 a slender darkened tip ; a small tuft of yellowish hairs on the margin 

 of the steruite just ventrad of the pleural suture.

Female. Length about 21 mm. ; wing 15'8 mm. 



Frontal prolongation of the head yellowish-orange, the uasus

 orange ; flagellum brown, the basal swellings of the segments darker 

 brown ; flagellar segments elongate-cylindrical, very slender, with long
