above downwards, extending from eye to eye, upper margin 

 raised into an angle in middle, somewhat concave on each side 

 of median line, lower margin very close to antenna?, above 

 which it is excavated ; a small but distinct clove-brown spot 

 in middle line below callus ; eyes in life with four horizontal 

 dark bands ; palpi ochraceous buff or sometimes isabella- 

 coloured, terminal joint elongate, but not attenuate, clothed 

 on outer side with short black hairs ; antennae russet-brown, 

 last three annuli of last joint dark brown or clove-brown, 

 first joint short and small, not incrassate, upper angle of 

 second joint not produced, third joint narrow, scarcely wider 

 at base. Thorax : dorsum with median grey stripe narrow 

 and entire, admedian stripes interrupted or more or less 

 indistinct after usual expansion behind transverse suture, 

 crescentic marks on hind margin present; pectus, pleurae, 

 and sides of dorsum yellowish grey or smoke-grey, a more or 

 less distinct horizontal dark brown streak on dorso-humeral 

 region immediately above dorso-pleural suture ; scutellum 

 yellowish grey or olive-grey, on dorsum with a pair of ad- 

 median olive-brown blotches, distal extremities of which 

 extend on to hind margin. Abdomen : median area of dorsum 

 of first segment except hind margin olive-brown ; dark sepia 

 blotches on second, third, and fourth segments somewhat 

 tapering, not reaching hind margins, with their bases resting 

 on front margins of segments and their inner borders slightly 

 curved, so that on each segment there is a narrow, elongate, 

 yellowish grey median triangle with its base resting on hind 

 margin ; fifth and sixth segments each with a pair of similar 

 but less distinct dark sepia admedian blotches ; on seventh 

 segment the blotches, if present, are fused together, so that 

 dorsum of this segment then appears almost wholly dark 

 sepia ; on fifth and following segments each dark sepia blotch 

 i> usually marked with a more or less distinct yellowish grey 

 fleck ; venter yellowish grey, with a more or less distinct dark 

 brown longitudinal median stripe, extreme hind margins of 

 segments for most part paler (cream-buff). Wings: pale 

 longitudinal streak occupies first posterior cell with exception 

 of distal portion, it is very sharply defined and is limited 

 above by third longitudinal vein, from about level of 

 distal extremity of discal cell onwards its lower margin 

 diverges from fourth longitudinal vein; first basal cell also 

 either entirely or almost entirely pale, second basal cell with 

 coarse double light marking at each extremity, the two pairs 

 of markings sometimes connected by a light bar immediately 

 below fourth longitudinal vein ; apical sinuous mark small 

 and inconspicuous, interrupted on upper branch of third
