Yery pale waxen-yellow ; flagellar joints of antennae smoky. 

 Thorax with three very indistinct pale fulvous stripes; posterior 

 half of metanotum brown. Abdomen pale prasinous. Thorax 

 levigate, with three longitudinal rows of yellow hairs, inter- 

 mediate one terminating at the middle; scutellum with long 

 yellow hairs. Halteres white. Abdomen nearly three times the 

 length of thorax, densely clothed with yellow hairs ; anal joint 

 and forceps narrower than last abdominal segment. Legs clothed 

 with very pale hairs. Tibial spurs black. In fore legs metatarsus 

 i longer than tibia. Wings rather longer than abdomen, pellucid, 

 almost hyaline, with brassy reflections ; veins yellow. Costal and 

 third longitudinal veins meeting somewhat before apex of wing ; 

 auxiliary vein extremely pale and indistinct, reaching costa at a 

 point somewhat beyond a point mid-way between middle cross-vein 

 and tip of first longitudinal ; first longitudinal vein reaching costa 

 much nearer to tip of costa than to middle cross- vein ; second 

 longitudinal vein very pale, indistinct, running close to first 

 longitudinal, joining costa at a point ^ the distance from tip of 

 first longitudinal to that of costa ; fourth longitudinal vein very 

 pale beyond cross-vein, little arcuated at base, almost reaching 

 wing-margin, terminating at a point situated J the distance from 

 tip of third longitudinal vein to that of anterior branch of fifth 

 longitudinal fork ; base of latter lying some distance beyond
