 numerous not very long rather inconspicuous whitish yellow hairs 

 which are almost entirely replaced by numerous longer conspicuous 

 black hairs on the postero- upper half; prothorax and pteropleurae 

 covered with abundant more longer very pale brownish yellow soft 

 rather shaggy hairs ; On the postero-upper margins of the meso- and 

 meta-pleurae there is a long dense conspicuous tuft of very pale yel- 

 lowish grey soft hairs. Scutellum as the thorax, but the black and 

 yellow pubescence- both more numerous and about the margin with a 

 dense rather depressed yellowish pubescence. 



Wings clear with the costal cell and stigma pale yellowish but 

 the latter sometimes very, slightly tinged with yellowish ; posterior 

 cells all widely open excepting of the first one which is contracting 

 towards the margin, discal cell moderately large and apparently longer
