marks on the basal half of the third, united at the base, reddish-orange ; 
the base of the first black ; a pale fuscous mark down the centre, united 
to a transverse narrower one on the apex ; in the centre of the third is 
a semicircular fuscous mark ; on the apex a broad transverse line, dilated 
in the middle, united to the basal central mark ; the basal two ventral 
segments paler orange ; wings fuscous-violaceous ; the stigma and nervures 
black ; the second cubital cellule shortly appendiculated ; the first and 
third transverse cubital nervures roundly curved, the second almost 
straight, obliquely sloped ; the transverse median nervure received very 
shortly beyond the transverse basal ; the first recurrent nervure received 
near the apex, the second in the middle of the cellule ; the anal nervure 
at the base is turned acutely downwards, forming a sharp angle ; radial 
cellule wide ; the basal two abscissae roundly curved, the third (which 
is shorter than the basal two united) straight, obliquely turned upwards ; 
accessory nervure in the hind wings interstitial. Female. •

Face and clypeus covered with a grey silky pile ; the apex of clypeus

from each other by the same distance as they are from the eyes ; pronotum 
large, as long as the mesonotum ; metanotum more opaque than the 
mesonotum, its sides broadly rounded ; tibial and tarsal spines black ; 
the basal joint of the fore tarsi closely spinose below ; there is no furrow 
on the metanotum, but its apical slope is slightly depressed, nor is there 
a furrow on the pronotum ; the mandibles are broadly red in the middle.
