darker areas are on anterior cord, at origin of Bs and a linear streak 

 in base of Isf A: whitish areas include a post-stigmal brightening; 

 a conspicuous obliterative area before cord, extending into bases of 

 cells iI/;V and iT/4; spots at base and near midlength of cells Cu and 

 1st A : bases of cells R and M brightened : cell Mi somewhat suffused 

 with whitish. 



Abdominal tergites brownish yellow, with a median brown stripe 

 that is narrowly interrupted at posterior margins of segments; sub- 

 lateral stripes obsolete; lateral borders not conspicuously pale; basal
