1888. Ent. Tidskrift, vol. 9, pp. 138, 139 (Tipida). 
A male specimen, without locality, but Bergroth'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 
7-6 mm. ; tibia 8-6 mm. ; hind leg, femur 9-1 mm. ; tibia 11-4 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 
steruo-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 
general terms the peculiar structure of the hypopygium without giving 
any intimation that it agreed with that of Lotujnrio. The general 
appearance of the fly is very similar to certain Nearctic species of 
Tip'ida of the tricolor grou}) (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, 
Lniujurio tesfaceus, Loew (North-Eastern Nearctic region), has a 
hypopygium of the same structui'e, the short notched tergite and the 
greatly produced ninth sterno-pleurite ])earing 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.
