A male specimen, without locality, but Berg-roth's original descrip- 

 tion gives Stellenbosch, near Cape Town. The fly gives the following 

 measurements : Length 10'2 mm. ; wing 12'3 mm. ; middle leg, femur 

 7'o mm. ; tibia 8'6 mm. ; hind leg, femur 9-1 mm. ; tibia 1T4 mm. The 

 male hypopygium (Plate XIII, fig. 48) has the ninth tergite (Plate XIV, 

 fig. -55) rather short with a deep U-shaped median notch, dark brown,' 

 the margin more yellowish ; the lobes with appressed black hairs 

 that are directed cephalad ; lateral lobes broad at their apices. Ninth 

 sterno-pleurite elongated, about two times the length of the tergite, 

 conical in lateral aspect, profoundly incised on the median line beneath; 

 pleural appendages elongated, lying in the dorsal concavity of the 

 sclerite, bearing along the dorsal edge a series of about five or six 

 .sharp black spines that are directed strongly cephalad ; these spines 

 are situated on the sharp edge of the appendage and in alignment. 



Bergroth, in his original description of this species, discussed in 

 gvneral terms the peculiar structure of the hypopygium without giving 

 any intimation that it agreed with that of Lonc/urio. The general 

 .appearance of the fly is very similar to certain Nearctic species of 

 Tqmla of the tricolor group (especially eluta, Loew), but the structure 

 of the male hypopygium as described above seems to indicate that the 

 present generic reference is more nearly correct. The genotype, 

 Lniiyurio testaceu*, Loew (North-Eastern Nearctic region), has a 

 hypopygium of the same structure, the short notched tergite and the 

 greatly produced ninth sterno-pleurite bearing the compressed pleural 

 appendages on their dorsal face 'and jutting into the tergal notch, 

 together with the profound incision of the sterno-pleurite beneath, 

 .so that the sclerite is completely bisected.
