288 NOVITATES ZOOLOOICAE XXII. 191S. 



Bod}' olivaconns mnmmv-lirnwn iihore, shaileil in ])liices witli wiilnnt-brown, 

 the hair-scales on head and thorax tipped with grey, mesonotum with grey oblique 

 stripe on the sides, abdomen with a double row of dark brown dorsal patches, on 

 segments ii, iii and iv an orange-yellow side-patch, the first and third patch 

 being smaller than the second and more transverse, the lateral tufts tipped with 

 white, anal fan entirely brown. On the iniderside the palpi, central area of breast 

 and a large patch on the first three abdominal sternites grey, an indication of 

 a grey spot also at base of the next sternites, rest of abdomen mnmmy-brown with 

 a tint of walnut, mnch less brightly coloured than in ^[. frulistorferi ; fore- and 

 midtibiae and -tarsi huffish grey, hindleg brown, tuft of hindtibia hazel. 



^^'i^gs, iipperside : Forewing sepia-brown, an autemedian black band partly 

 filled in with sepia-colour, widest at hindmargin, reaching costa proximally to 

 apex of cell, basal area below cell with a streak of grey-tipped long scales from 

 base to antemedian band; a grey discoeellnlar transverse spot followed at hind- 

 margin by a grey triangular sput, outside this interrupted band two black lines, 

 incurved in centre, excurved below costa, parallel up to M', then diverging and 

 from R' converging, the outer line more strongly excnrved at R' than the inner 

 and in front of this vein exteriorly bordered with grey, between these lines and 

 ilistal margin, and almost parallel with them, a grey line wliicli is slightly broken 

 (not interrupted) at 11' and forms a right angle between the median veins, reaching 

 the hindmargin lA mm. from distal edge, and costal margin 4i mm. from apex, 

 outside this grey line and partly fused with it another grey line comiuencing at 

 R' and disappearing before reaching hindmargin, costally to this line, i.e. in front 

 of R', a deep brown patch preceded in front of SC° by a diffase chestnut patch, at 

 apex the usual dark angle slightly outlined in grey, veins R' and SC^ partly streaked 



with grey. Hindwing orange-yellow, the extreme base and a sharply defined 



marginal band deep chestnut-brown, the band 4 mm. broad in centre, from below 

 costal margin to below M- of nearly even width, then suddenly narrowed, being 

 only li mm. broad at anal angle, fringe of abdominal margin brown. 



I'mhfsiJe : Ground-colour a pale dnil chestnut, shaded over with tawn3'-olive, 

 much less bright than in M. fnihstoifcri, distal marginal band deeper brown, 

 extreme base of wings pale yellow, hind wing with orange-yellow elongate patch 

 before hindmargin, extending to base, but not to margins. 



Tenth abdominal (= anal) tergite gradually narrowed distally, with the tip 

 trnncate-rotundate ; sternite spatulate, broader than the tergite, slightly acuminate, 

 with the edges minutely serrate. Clasper without friction-scales ; harpe very 

 slender, almost cylindrical from near base to near apex, the tip deeper brown, 

 narrower, curved upwards, slightly s|>atulate, no teeth, but before the curved-up 

 apical ]iortiou a slight ventral hump bearing some bristles. Penis-sheath uearly 

 as in M. calescens Butl. (1882), the apical process horizontal, very long, ending 

 in a long thin whip; this process, which encircles three-fourths of the penis-sheath, 

 bears some teeth at the ventral edge of the wide basal half, and there is a patch 

 of teeth on the jienis-sheatli pniximally to the base of the process ; apical edge of 

 sheath not produced into a lobe opposite the base of the process ; inside the sheath 

 one (?) rod only, which is obtuse. 



The specimen also resembles M. calescens Butl. (1882), and M. cualancum 

 1{. & J. (1903), but is easily recognised by the more prominent grey markings 

 on the upperside of the forewing and the grey patches on the underside of the 

 abdomen.
