cells in alignment with the fourth and fifth radial blotches 
described above; veins C, Sc, and R yellow; remaining 
veins dark brown. Venation: Sc, retracted far back from 
the tip of Sc,, lying about midway between the origin of Rs 
and the tip of Sc,; Rs long, arcuated at origin; cell R; very 
wide at the wing-margin ; basal deflection of Cu, some 
distance before the fork of M, in some specimens this dis- 
tance being greater than the deflection of Cw, in others 
less. , 
Abdominal tergites yellow, the intermediate segments 
with two broad brown cross-bands, one basal, the other 
postmedial, about equal in width to the yellow apices and 
much broader than the yellow band between them; the first

narrowed to the tip ; pleural appendages two, the outermost 
slender, arcuated, chitinized ; inner appendage longer, stout
