Bergroth's specimen (No. 1), without locality, but in the paper 

 cited above given as " Cape Town." The specimen is a male measuring 

 12'4 mm. in length, and the wing 13'5 mm. 



The wing is shown on Plate XII, tig. 38. 



The coloration of the thorax, well described by Bergroth, offers a 

 very good specific character ; the middle thoracic stripe is not as dark 

 in colour as the lateral stripes and is narrowed toward the caudal 

 end, not attaining the transverse suture ; the opaque black line 

 surrounds the lateral stripe except a small portion on the outside ; 

 the same intense marking occupies the lateral portions of the trans- 

 verse suture and runs caudad as a small spot above the wing-root ; 

 postnotum with a distinct brown median mark. Hypopygium with 

 the ninth tergite (Plate XIV, tig. 64) short, broad, the caudal margin 

 with a very broad and deep U-shaped notch with a low, obtuse, 

 median tooth ; outer pleural appendage pale, large, very conspicuous.

Frontal prolongation of the head short, uasus slender; palpi yellowish- 

 brown, darker toward the tip. Antennae moderately elongated ; first

 the genae ; a large rounded blackish spot near the base of the frontal 

 tubercle and adjoining the inner margin of the eye ; occipital triangle 

 prominent, shiny, dark brown.

 yellow with three black stripes, the median stripe with the central
