suture by an equally broad, slightly arched stripe, which reaches 

 humeral spot; a black notopleural stripe, sutural callosities 

 yellow. Pleura shining black, reddish on propleural region ; 

 mesopleuron with a broad yellow patch, continued below with 

 a broad rounded spot on upper part of sternopleuron ; a double 

 yellow hypopleural spot; mesophragma entirely shining black. 

 Scutellum entirely yellow with a very narrow black basal stripe ; 

 it has only the apical pair of bristles. All the bristles black; 

 middle scapular strong, but shorter than those of outer pair; 

 pteropleural well developed ; prescutellar long ; one anterior 

 supra-alar. Squamulae dark, with pale hairs; halteres whitish. 



Abdomen rounded, with distinct segmentation, broader than 

 thorax, reddish, finely punctulate, rather shining, with a short 

 pale yellowish pubescence. Whole of first and second segments 

 narrowly black on sides and with a black transverse stripe on 

 the middle not extending to sides ; hind half of second segment, 

 beyond the transverse black stripe, paler and more yellowish; 

 third segment black at base and on sides, forming thus a second 

 black crossband, the latter broadened laterally and extending 

 to the black sides; fourth and fifth segments black on sides; a 

 black middle stripe, very narrow at the black basal border of 

 third segment, becoming broader on fourth and fifth segments 

 and reaching the end of the last; fifth segment entirely shining, 

 its usual patches not distinct. Venter entirely reddish, with 

 black borders; ovipositor entirely reddish and shining, flattened, 

 with basal segment a little infuscated apically. Legs and coxa? 

 pale yellowish, with hind tarsi whitish; middle tibia black on 

 basal and whitish on apical half; hind tibiae quite black; the 

 short pubescence of legs with the color of the parts on which 

 it occurs ; spur of middle tibise black. 



Wings (Plate I, fig. 6) hyaline and iridescent, proportionally 

 narrow; second longitudinal vein straight; third slightly bent 

 downward at end; last portion of fourth vein slightly curved 

 at base; small cross vein beyond middle of discoidal cell. Pat- 

 tern very simple, consisting only of a narrow brown fore border, 

 which includes the darker stigma, extends below T not beyond 

 second longitudinal vein, fills up the end of submarginal cell 

 and the whole end of first posterior cell, being there rather broad 

 with an oblique inner border and reaching the end of fourth 

 vein. Costal cells and the part of first basal cell just above the 

 dilated second basal cell infuscated; third posterior cell slightly 

 infuscated at base near anal cell, but there is no distinct brown 

 anal stripe.
