5. Length of body, 6 "5 nun. ; length of wing, 5 '5 -mm. Occiput entirely black, 

 and very glistening ; at the middle of the upper border, just behind and below the 

 vertex, there is a faintly developed, yellowish spot ; there is no yellow ocular border 

 on the upper half, but a broad yellow spot near the eyes on the lower half, contiguous 

 with the yellow jowls. Frons with more than the basal half black, while the rest 

 is yellow ; but the black basal part has a yellowish spot on each side just in front 

 of the vertical plates ; it is opaque, but shining at base and on sides ; lunula shining 

 black ; it seems that two pairs of lower orbital bristles are present. Antennae with 

 the first joint shorter than the second ; they are infuscated, almost black on the 

 outer side, pale yellowish inwardly at end of the 2nd and at base of the 3rd joint ; 

 arista with yellowish base. Face shining yellow, with quite unspotted antennal 

 grooves ; cheeks more whitish ; jowls yellow, quite unspotted. Palpi and proboscis 

 yellowish. All the cephalic bristles are black. Thorax entirely, black, rather 

 shining, even glistening in front and on sides, punctate ; the pale yellowish markings 

 are as follows : an elongate spot, occupying about the whole of the humeral calli, 

 except the upper anterior part ; an oblique and more whitish spot on each side of 

 the suture, in contact with the dorsocentral line inwardly, but far apart from the 

 sutural calli, which are shining black ; a broad, middle patch on the pleurae, including 

 about the whole of meso- and pteropleura, continued below as a rounded spot on

 long pubescence of the back is whitish, like that of the pleurae ; the long hairs on 

 the breast are white. Macrochaetae black ; middle scapulars wanting ; no trace of 

 anterior supra-alars ; pteropleurals well developed ; two scutellars. Halteres whitish. 

 Abdomen rather narrow and long, of elongate-oval shape, entirely black, punctate

 are darkened distally. Costal, marginal and submarginal cells very narrow ; stigma 

 long ; fifth segment of the costa considerably longer than the preceding one ; third 

 longitudinal vein strongly curved downwards beyond the middle of its last portion ; 

 first posterior cell very broad ; lower end of the small cross-vein placed a httle after 

 the middle of the discoidal cell ; last portion of the fourth vein almost straight, being 

 only a httle curved near the base ; prolongation of the anal cell very narrow and very
