Tie Crane-flies of South Africa. 207 



Mesouotal praescutum greyish-yellow with three dark brown stripes, 

 the median one narrowed to the transverse suture ; lateral stripes 

 narrow. Pseudo-sutural foveae very conspicuous, semi-circular, black, 

 shiny. Remainder of the mesouotum greyish-yellow, pruinose, the 

 scutal lobes darker. Pleura dark brown, a conspicuous broad silvery 

 grey stripe across the mesopleura, extending from the fore coxae to 

 above the base of the middle coxae. Mesosternum dark brown, more or 

 less silvery-grey pruiuose. Halteres pale at base, the knobs brown. 

 Legs with the coxae pale, grey pruinose ; trochanters yellow ; remainder 

 of the legs broken. Wings with a faint grey tinge, the membrane 

 heavily dotted with brown along the veins and outer margin. The 

 pattern is as follows : larger and darker brown marks at the origin of 

 Ps, at about mid-length of R, where there are three confluent dark 

 brown spots in cell Sc, the tip of 8c l and presumably at the tip of R^ ; 

 this region of the wing injured in the unique type ; paler brown dots 

 along the veins and at regular intervals along the wing margin, the 

 largest at the ends of the longitudinal veins ; in cell C the dots are 

 very small, pale and few in number ; there are about four dots along 

 Es, about eight along M, about twelve very distinct clouds along Cu 

 before its fork, seven along '2nd A, and about four or five along the 

 margin of the wing in cell 2nd A. Veins light brown, costa more 

 yellowish. Venation : Sc ending just beyond the fork of Rs ; Rs 

 moderately long, strongly angulated and slightly spurred at its origin ; 

 basal deflection of -B 4 + 5 about as long, or a trifle shorter than the 

 basal deflection of Cu-^ ; r-m about twice the length of the very short 

 m ; cell 1st M. 2 small, subquadrate, about as long as the basal deflec- 

 tion of CWj, which is inserted at about the middle of its length ; 

 terminal section of Cu } nearly twice the length of cell 1st M 2 ; second 

 aual vein strongly curved at its tip. 



Abdominal tergites dark brown, the basal sternites more yellowish.
