nae dull fuscous; pronotum yellow-brown with two spots on callus 
of disk anteriorly, three large spots near posterior margin, four spots 
on each side behind lateral carinae, two spots on each side between

band, indented at middle, transversely between costa and apex of 
¢clavus, membrane beyond nodal line minutely transversely barred, a 
broad interrupted band of black and yellow-brown approximately 
parallel to apical margin, apical margin barred with about six dark —
