 tudinal stripe (slightly broader posteriorly), a pair of ad- 

 median stripes (interrupted beyond transverse suture), and a 

 short and broader stripe on each side, extending from upper 

 angle of praisutural depression to bind border and continued 

 round scutellum, light grey or pearl-grey ; usual crescentic 

 marks on hind border (contiiuiations of aHmedian stripes)

 expanding clove-brown median stripe, interrupted on hind 

 margins of segments, starting on third segment and extending 

 to distal extremity. Wings very similar in coloration and 

 markings to those of H. insidiatrix , Ansten, but pale 

 markings not quite so light in colour and slightly coarser, 

 and no trace of light fleck near distal margin of second sub- 

 marginal cell, beyond apical sinuous mark ; stigma seal- 

 brown, conspicuous, of moderate length, wit!i a distinct light 

 mark running up to costa at its proximal extremity ; no 

 conspicuous dark blotch below stigma; discal cell with two 

 approximate transverse light marks (distal one divided) in its 

 middle portion, a large light spot in its distal third, and a 

 minute and indistinct light fleck near its proximal extre- 

 mity ; disconnected oblique light marks across posterior cells 

 divided or partly divided ; a series of not very conspicuous 

 light blotches along hind margin, in distal angles of posterior 

 cells except fourth; some minute light flecks near distal 

 extremity of anal cell; light markings in basal, anal, and 

 axillary cells of normal type, zigzag mark and light loop in 

 axillaiy cell conspicuous but not connected, light blotch on 

 sixth vein beyond zigzag mark of fairly large size and distinct ; 

 ulula with pale border. Halteres cream-buff, knob pale seal-
