The Crane-flies of South Africa. 185 



Type in the South African Museum. 



This species agrees closely with the type of the sub-genus, G. immacu- 

 lata, Edwards, in the subgeneric characters ; it is a much larger species 

 (immaculata, $ , length 5 mm. ; wing 5 - 5 mm.), with the venation and 

 coloration different. Edwards' figure of immaculata shows cross-vein 

 r very long and strongly deflected at its outer end. 



GrEKANOMYIA (GrERANOMYIA) SEX-OCELLATA, Sp. U. 



Eostrum long, black; legs brownish-black; wings with a heavy 

 ocellate pattern along the costal margin. 



Male. Length, excluding rostrum, 7'5 mm. ; rostrum alone, 4'3 mm.; 

 wing, 7' 7 mm.; hind legs, femur, 6'8 mm.; tibia, 7' 7 mm. 



Eostrum elongate, black, the paraglossae strongly recurved at their 

 tips, with sparse hairs along the margin ; palpi small, black, apparently 

 two-segmented ; between the paraglossae a straight, slender rod that 

 is deeply bifid at its apex. Antennae black, the flagellar segments 

 short-oval. Head blackish, discoloured in the type. 



Thoracic dorsum discoloured in type, reddish-brown, paler along the 

 margin of the praescutum ; an indistinct darker median stripe ; 

 scutellum reddish-brown with a narrow median brown line ; postnotum 

 brownish-black. Pleura reddish-yellow, with a narrow dark brown 

 dorsal stripe extending from the cervical sclerites backward, becoming 

 indistinct beneath the wing-root. Halteres brown, the knobs dark 

 brown. Legs with the coxae and trochauters dull yellow, femora dark 

 brown, brighter at the base ; tibiae and tarsi brownish-black. Wings 



o 



subhyaline, the cells iu the posterior half of the wing more greyish ; 

 along the costal margin a series of seven brown markings, all except 

 the last of which possess large brownish -yellow centres to produce 

 an ocellate appearance; the largest of these ocellate blotches are 

 located at the origin of Es, tip of Sc and tip of E l ; in shape they 

 are broadest along the costal margin, narrowed posteriorly, the first 

 and third reaching vein J/, the fifth and sixth reaching -R 4 + 5 ; the 

 seventh, solid, marking is the smallest, located at the tip of -R 4 + 5 ; 

 heavy brown seams along the cord and the outer end of cell 1st N z ; 

 a small brown spot at the tip of 1st A and a much larger one at the 

 tip of 2nd A. Venation : Sc long, ending slightly before the fork of 

 the sector, Sc. 2 at the tip of 8^ ; Rs long, strongly angulated at its 

 origin, about twice the length of the deflection of -K 4 + 5 ; r at the 

 tip of Ej ; r-m short ; cell 1st 3/ 2 long, the veins issuing from it 

 short; basal deflection of Cu^ far before the fork of 31, Ci^ + M 

 being more than half the length of the basal deflection of Cu } 

 alone.
