MICROLEPIDOPTERA OF NEW GUINEA 
t 
irregularly rounded black dots, ultimate dot well before the apex; an 
irregular streak of black irroration mixed with dark grey along the dorsum, 
forming an almost isolated semioval patch along the basal fifth (with a 
small appressed tuft of pale ochreous scales beyond the middle of the base 
of wing), and a flattened-triangular patch at 1 / 3 of the dorsum; this black 
streak twice interrupted by white ground colour posteriorly; a line of 
grey-olive irroration forming an ovate loop on the base, originating from 
the first dorsal patch; a broad somewhat irregular vertical submedian 
transverse band of grey-olive irroration edged with white raised scales, 
mixed with white and traversed by white ground colour along the fold; a 
vertical transverse fuscous blotch beyond preceding, reaching 2 / 3 across 
wing, irregularly constricted in the middle; a transverse band at 2 / 3 , 
somewhat outwardly oblique, from the dorsum before the tornus, not 
reaching costa, grey with olive (and blue) opalescense, anterior and poste- 
rior edges black; anterior narrow, twice deeply zigzagged, posterior edge 
broad, outwardly concave; followed by an irregular transverse spot of 
fuscous irroration from below the costa to below the middle of the disc, 
connected above with the penultimate pair of the costal dots, posterior 
edge with two short parallel slightly inwards-oblique, almost horizontal 
black streaks, running along the lower edge and below the costa ; posterior 
edge deeply concave between these; an interrupted row of black scales 
scattered below costa from beyond the base to the middle; a subterminal 
transverse patch from before the apex to before the lower third of the 
termen; apex and termen with a row of dark grey dots. Cilia dark grey 
with two-three minute transverse whitish lines. Hind wing glossy, sordid 
whitish, posterior half gradually becoming fuscous towards apex; cilia 
grey-fuscous with whitish tips. 
Gnathos gradually narrowed towards the apex, somewhat shorter than 
in the preceding species, with a broader base. Basal projection of the 
sacculus small. Aedoeagus rather long, sinuate, the basal third bulbate.
