bristles from lower edge of facial carina to back of head. 
Postocular area laterally blue dusted, sharply defined from 
yellow genal area below. Proboscis yellow, geniculate. 
Antenne brownish-yellow, second joint spinulose at tip, with 
an upper and two lower erect bristles apically. Third joint 
twice as long as first and second together, microscopically pale 
pubescent. Arista long, minutely pubescent, black except for 
extreme base, yellowish. 
Thorax dark brown-yellow, violet-gray dusted. A median 
and two dorso-central somewhat ill-defined narrow yellow 
stripes, the median continued to tip of concolorous scutellum. 
Pleure concolorous, a yellow line along dorso- and sterno- 
pleural sutures, widened posteriorly over most of ptero- and 
hypo-pleure. Przscutellar present, dorso-centrals three, the 
anterior at about one-third from front margin of thorax, 
humeral and posthumerals (2) strong, presutural weak. 
Meso-pleural and sterno-pleural strong, ptero-pleural wanting. 
Anterior supra-alar strong. Scutellum with four strong 
bristles, apicals parallel. All thoracic bristles black. 
Abdomen.—Dark or pale brown, paler ventrally, black 
pubescent. Genitalia consist of a broad brown-yeliow plate 
bearing apically a pair of prominent bristiy black lamelle. 
Legs.—Pale yellowish, except apical four joints of fore tarsi, 
which are dark. Fore femora with a number of stiff hairs 
above and below, posterior femora nearly bare, and with a 
small bristle before tip. Fore and hind tibize with pre-apical 
bristle, mid tibize with extensor surface bristle much nearer 
tip and thicker. 
Wings.—Pale gray, a dark suffusion above second vein, 
behind which it gradually merges into ground colour of wing. 
Cross-veins, especially posterior, somewhat suffused. Auxi- 
liary vein distinct throughout from first vein, which ends a 
little beyond it at about one-third of wing. Second, third, 
and fourth veins approximately parallel, third ending at wing 
tip. Anterior cross-vein at middle of discal cell, posterior 
cross-vein at less than its own length from tip of fifth vein. 
Anal cell as long as second posterior. :
