with an exterior brown streak, which proceeds almost straight across

2. Ganisa plana. 



Mas. Cinereo-fusca ; antennce testacece ; alee glaucescentes fasciis 

 plurimis linearibus undulosis obliquis fuscis ; anticce fascia 

 angusta duplicata fusca ; postica fascia unica extus e guttis 

 fuscis marginata. 



Male. Cinereous-brown, a little paler beneath. Antenna? tes- 

 taceous. Wings with glaucous reflections, and with numerous 

 slender undulating oblique brown bands, which are less apparent on 

 the upper side of the hind wings ; under side with a brown discal 

 dot on each wing. Fore wings with a slender double brown band, 

 which extends from the tips to a little before two-thirds of the inte- 

 rior border. Hind wings with a slender and sometimes obsolete 

 brown band which is near the exterior border, and has a row of mi- 

 nute brown dots along its outer side. This species much resembles 

 G. postica, but may be distinguished by the straight band of the fore 

 wings by the band of the hind wings, which in G. postica is further 

 from the exterior border, and not accompanied by brown dots, and 

 by the form of the hind wings, which in G. plana are more oblique 

 and less convex along the fore part of the exterior border. Length 

 of the body 8 — 9 lines ; of the wings 26 — 28 lines.
