basal cell. First vein ending opposite the small cross-vein. Thorax wholly yellow, 

 without black lateral streaks. 



24. Rioxa quinquemaculata, n. sp. ? . 

 (PI. ix, fig. 27.) 



In this small-sized, narrow elongate, slender species, the black wings are devoid 

 of hyaline discal spots and show only five marginal indentations. Length 7 mm., 

 with the ovipositor. 



This species is very like sexmaculata , Wulp, but easily distinguished by the 

 unstriped pleura , the absence of bristles on the legs , and the wings with only five 

 marginal hyaline indentations. Both these species seem to be congeneric with the 

 type species lanceolata of Walker. 



Head reddish yellow, very broad and low; antennae darkened, the third joint 

 quadrangular ; arista pectinate, with distant and long hairs on the upper side only ; 

 eyes round ; cheeks narrow ; two black lower or. ; of the superior or. the superior is 

 yellow and the inferior black; no oc; pvt. yellow; two vt., the outer black, the 

 inner wanting ; genal bristle black, and after this some other black bristles ; the 

 bristles of the occipital row are well developed, black. 



Thorax damaged ; it seems to be dark reddish yellow, the pleura cinereous and 

 not striped; all the bristles black; intermediate bristle of the scutellum weak. 

 Haltères darkened. 



Abdomen narrow elongate, shining black, with a broad ferruginous median 

 longitudinal band ; the 6th segment wholly black like the ovipositor, which is as long 

 as the four last segments together ; some short bristles on the sides of the last three 

 segments ; pubescence blackish. Legs wholly yellow, short but not very slender ; 

 front femora with 3-4 bristles beneath ; middle legs without bristles. 



Wings as in sexmaculata ; but the first hyaline marginal spot on the stigma 

 wholly wanting ; the four other spots are in the same position ; the 5th is not at the 

 end of the 6th vein, but in the middle between the ends of the 5th and 6th vein. 

 First vein ending in the middle between the auxiliary and the second vein ; the point 

 of the anal cell very broad and short, but a little longer than the second basal cell; 

 no distinct costal bristle. 



A single specimen from Tenasserim, Lower Burma (W . Doherty) -ff ^. 



This species seems to be closely allied to the recently described R. sumatrana,

Very distinct from all the other species by reason of the Tephritis-like patteru 

 of the wings.
