Similar to Protoparce (P. Convolvuli) : forewiug sliglitly broader and the 

 exterior margin even ; middle median emitted at one-fourth and lower at one-half 

 before end of the cell : hindmng with a more oblique, and even exterior margin ;

 Porewing light grey, with two or three whitish spots on basal half of the costa 

 and at centre of discoidal cell ; a double angulated discal series of brownish-edged 

 lunate spots ; a small oblique spot towards middle of costa, a less oblique streak 

 crossing the cell near its end, two parallel streaks within the interspaces, a small 

 lunule beneath them, an irregular streak margining the apical patch, and a series of
