Diacrotricha guttuligera spec. nov. (fig. 2) 
t? 16 mm. Head, thorax white. Antenna white, basal half ringed with 
dark fuscous above; ciliations 1 / 2 . (Palpi broken.) Abdomen whitish

posterior tarsus moderately thickened with appresscd hairs above. Fore 
wing cleft from before middle, segments linear. Creamy ? (both fore and 
hind wing have become greasy). A blackish streak along anterior half of 
costa, posteriorly becoming fuscous and ill-defined; a coarse fuscous 
speckling: below costa from base to cleft, thence extending over first 
segment and forming a small ill-defined streak along base of dorsum of 
latter; a streak of this speckling along dorsum of wing not reaching base 
of cleft ; first segment with two elongate blackish dots : on and well beyond 
middle of costa, respectively; a minute longitudinal blackish strigula in 
apex; two small streaks of blackish-fuscous irroration on dorsum of first 
segment: beyond middle (between costal dots), and at 3 / 4 ; second segment 
with a minute blackish dorsal streak beyond base of cleft and two elongate 
black dots: beyond middle and beyond 3 / 4 of dorsum, hardly reaching 
above middle of segment, first one largest, followed by a few blackish 
scales; a black point in apex. Cilia pale fuscous-creamy along costa,
