180. Microgonia subumbrata spec, no v. 



Forewing : olive-green, with a few darker transverse striae ; first Hue from 

 one-fourth of costa to one-third of inner margin, indistinct, slightly ontcurved 

 above and below the median vein, darker olive mixed with rufous scales ; 

 faintly double, and preceded by a dark spot on median ; an oblique darker olive 

 shade from middle of costa, narrow at first, then widening out and joining the 

 deep lolive shade that precedes the outer line ; this is dark olive-brown edged 

 outwardly with rosy grey, starting at five-sixths of costa, sharply angled on 

 vein 7 before apex, then oblique and nearly straight to beyond middle of inner 

 margin ; the outer rosy grey arm is marked externally by dark olive spots on 

 the veins ; marginal area occupied from vein 4 to anal angle by a dark olive 

 blotch narrowing to the angle, the teeth of the submarginal line marked by 

 white dashes ; fringe reddish olive ; cell-spot black with pale edge. 



Hindwing : with the line slightly antemedian ; submarginal line indicated 

 by a diiFuse rufous zigzag shade, the teeth marked white. 



Underside uniform dark olive-grey with a broad submarginal diffuse 

 fascia of pale olive, enlarged at each anal angle and paler at apex of forewing ; 

 a line of submarginal pale dashes ; cell-spot pale iu forewing, black in hind- 

 wing ; inner margin of hindwing pale olive. 



Thorax pale olive like the wings ; abdomen olive-grey, with a rufous tinge ; 

 head darker, mixed with rufous ; pectus and underside of abdomen dark olive- 

 grey, the pectus hairy ; legs pale olive ochreous dotted with fuscous. 



Expanse of wings ; 58 mm. 



1 ?, from Santo Domingo, Carabaya, S.E. Peru, 6000 ft., November 1902, 

 wet season (Ockenden). 



The npperside agrees well with the description of olivata Dogu., but the 

 underside is altogether different. 



181. Microgonia umbrosa Sehaus, ab. interclarata nov. 



This aberration of M. umbrosa is analogous to that of Ji. apidania Cram., 

 which I described under the name of bicolor (Nov. Zool. iv. p. 494, 1897). 

 The central area of forewing between the two lines is brownish olive with 

 sparse striatiou, instead of being thickly striated and suifused with dark ; by 

 way of compensation, the dark tints of the basal and marginal areas are intensified 

 from brown to black ; while the whole of the hindwing except the marginal 

 area from apex to vein 4 is dull black. The example described is one of 15 cJc? 

 from Huancabamba, Cerro de Pasco', Peru, 6000 — 10,000 feet (BOttger) ; among 

 these four others differ from the type form in having the outer line pale olive- 

 yellow instead of dark brown. 



182. Microxydia rufifimbriata spec. nov. 

 Forewing: glossy straw-colour, with very fine reddish dusting; costal edge 

 bright red, thickened from base to first line and from second line to apex ; lines 

 bright red ; first fine, from one-fourth of costa to one-third of inner margin, bent 

 in cell ; second double, from two-thirds of costa to three-fifths of inner margin, 

 bent on vein 6 and marked there externally by a black point ; generally with 

 slightly darker points on all the veins ; cell-spot small, red ; fringe full, deep red. 

 Hindwing : with the double line central, not reaching above vein
