Redescription. 



c? $ . Head varying from yellow to reddish brown ; proboscis 

 above and at tip darker brownish, palpi yellowish. Antenual 

 scape yellow, flagellum black, the joints slightly but distinctly 

 enlarged at base where they bear the usual verticillate hairs. 

 Thorax varying from yellow to orange and reddish brown ; the 

 three usual dorsal stripes, the middle one nearly always very 

 indistinct on the anterior part, this indistinctness sometimes 

 extending back to the middle of the stripe ; the outer ones often, 

 but not always, indistinct at their tips, never curved outwards or 

 downwards ; post-sutural stripes sometimes contiguous to those 

 in front, the narrow black streak in front of the wing and below 

 the edge of the dorsuin rather more conspicuous than usual. 

 Scutellum mainly blackish ; metanotum with upper half yellowish, 

 sometimes with a thin median dark line, lower half blackish. 

 Abdomen normally brownish yellow, but varying considerably in 

 shade towards entirely yellow or entirely reddish brown ; the 

 black markings very variable, forming sometimes an elongate black 

 spot on each segment, more or less widened on the hind margin, 

 the dorsum of the apical segment generally wholly black or nearly 

 so ; sometimes occupying nearly all the dorsum on u\\ the seg- 

 ments ; sometimes barely widened posteriorly, especially in the 

 male and on the basal segments. In the female, the black colour 

 is more extensive, often filling the entire dorsal surface. Belly 

 mainly yellowish but blackish towards the tip. Gemtalia con- 

 spicuous, brownish yellow, consisting of an oblong rather small 

 dorsal plate, a pair of claspers, of which the basal joint is normally 

 constructed, with a large flattened, almost leaf-shaped, pointed 

 second joint, which bears on the inner side a narrow black finger- 

 like appendage ; some smaller intermediate organs are apparent. 

 Ovipositor brownish yellow, shining, bare, normal. Leys brownish 

 yellow, extreme tips of femora and tibiae very narrowly black, 

 apical half of tarsi blackish. Wings pale grey, subcostal cell 

 brown ; stigma brownish, varying in intensity ; prongs of upper 

 branch of 4th longitudinal vein issuing generally widely separated, 

 occasionally simultaneously or nearly so, but 2nd posterior cell 

 never petiolate. Halteres dark yellowish brown. 



Length 13-21 millim. 



Redescribed from a good series in the Ptisa collection, all from 

 Pusa (except one) bearing dates of every month except May, June, 

 and December, the species apparently occurring there nearly all 

 the year. One specimen is from Chapra, Bengal, undated. One 

 specimen in the Indian Museum from Katihar, Purneah district, 

 Bengal, 7-31. viii. 10 (Paiva). 



Type in the British Museum. 



The principal feature of this species is its reddish brown colour, 

 and the obliteration of the anterior end of the median thoracic 

 stripe.
