c?. 25 — 32 mm. Head and thorax grey; sometimes an oehreous-tinged tuft 

 of hairs in front of antenna. Palpi 2; dark-fuscous; terminal joint and apex 

 of second joint whitish-oclireous. Antennae whitish, irrorated with fuscous; 

 pectinations fuscous. Abdomen grey. Legs grey with .some whitish hairs. 

 Forewings broadly trimigular, costa short, straight, apex very obtusely rounded, 

 termen rounded, scarcely oblique; markings very distinct, dark-fuscous, inter- 

 ruptedly edged with whitisli-oehreovis ; a line from ^ eosta obliquely outwards 

 to mid-disc, then obliquely inwards to J dorsum, with a small outward tooth 

 above dorsum; second line from f costa to | dorsum slightly wavy, toothed out- 

 wards abo\e middle; a short bar sometimes connects the two lines in middle of 

 disc; sometimes a subterminal line of short streaks on veins; cilia gTey. Hind- 

 wings with termen strongly rounded; pale-grey; sometimes a pale-fuscous, 

 angulated, antemedian line; sometimes faint fuscous streaks on veins forming 

 a subterminal line; cilia pale-grey. Underside grey; a fuscous median line on 

 both wing's.

Palpi moderate, porreet; second joint witli loose or appressed liairs; ter- 

 minal joint short or minute. Posterior tibiae without middle spurs. Fore- 

 wing's with 4 and 5 separate, all veins from areole separate, subapical crossbar 

 from 10 to 9 shortly beyond their bifurcation, sometimes partly or wholly coin- 

 cident with 9. Hiudwings with 4 and 5 separate, 6 and 7 approximated, con- 

 nate, or stalked, 12 gradually diverging from cell, connected with it before 

 middle by 11, which is often imperfectly or not developed. 



Type, ^1. ferruyinosa Wlk. 



A large genus with some variations in the palpi and neuration, but the 

 latter occur within the limits of the same species in many instances. I recog- 

 nise 40 species, of which 11 are here described for the first time. Deducting 

 these, there remain 29 species, which have received no fewer than 87 names. 

 This excessive synonjmiy is due to the great variability of many of the species not 

 having been previously recognised. The sexes often diffei', sometimes con- 

 siderably, in colour, wing-shape, and distinctness of marking. Apart from sexual 

 differences, many species vary much in colour, and in the development of lines 

 on the wings; in some examples these may be vei-y distinct and characteristic, 

 in others of the same species they may be completely obsolete. 



Owing to the variability of some of the species the following talnilation must 

 be used with cavition : — 



1. Wings wholly miicolorcius 2 



Wmgs not wholly unicolorous 7 



2. Forewings wirh apex obtusely roundetl 3 



Forewiii.ss more or less pointed 4
