Imago. — Upperside olivaceous oclireous-brown ; with a very indistinct pale trans- 

 verse discal straight narrow fascia on both wings ; marginal lines pale ochreous- 

 brown. Cilia pale ochreous. Forewing with a prominent large ocellus between the 

 lower median veins. Eindwing in male sometimes with a very small lower median 

 ocellus, and in the female with one, or sometimes two indistinctly visible subanal 

 ocelli. Underside cinerescent-brown, with a more or less well-defined transverse 

 discal ochreous-white or greyish-white band on both wings ; marginal lunular lines 

 ochreous-white and prominent. Foreichg with a prominent small subapical ocellus, 

 and a large lower median ocellus, each separately encircled by a greyish-white outer 

 ring ; very rarely a specimen occurs in which each ocellus has a minute attached 

 ocellule, and then all are encompassed by the outer greyish-white line. Hindwing with 

 seven prominent ocelli, of which the second, third, and seventh are the smallest, and all 

 encompassed by a greyish-white outer wavy line. Male, on the upperside of the 

 Mndioing with a subbasal tuft of pale ochreous hairs overlapping a glandular patch 

 of hIacJdsh scales; and on the underside of the /o/-e?y/H^ with a glandular patch of 

 blackish scales on the middle of the submedian vein. The patch, as seen under the 

 microscope, is composed of densely-packed but loosely raised, overlapping, large, 

 broad, oval scales with even front edges. Compared with the patch of yellow scales 

 on the forewing of G. Visala, that of G. Mineus is two-thirds less in size, the scales are 

 less closely packed, are more laxly raised, and are narrower both anteriorly and 

 posteriorly. Body beneath, legs, and streaks on sides of palpi pale cinereous- 

 brown. 



Expanse, If to 2 inches.
