EXOTIC MICROLEPIDOPTERA, 
leaden-grey, a basal patch of dark grey and black occupying about | 
of wing; otherwise extremely similar and may prove to be only a 
geographical form, though apparently constant. 
Sumatra, Pematang Siantar, bred September, February from 
larvae found occasionally on tea-plant (P. I. Nel) ; 3 ex. (type 
Brit. Mus.). 
Gypsonoma riparia, n. sp. 
6 2 • 9-11 mm. Head grey, face ochreous-whitish. Palpi 
grey, tip white. Thorax grey. Forewings elongate, costa anteriorly 
gently arched, termen hardly sinuate, somewhat oblique ; pale 
whitish-ochreous ; a dark grey basal patch occupying ^ of wing, 
edge slightly rounded, hardly oblique; costal edge from this to 
apex white, with several small dark grey spots; central fascia 
rather oblique, grey, widest and most distinct in disc, on dorsum 
preceded by a triangular pale ochreous spot; apical area more or 
less suffused light grey except costa, a small roundish fuscous apical 
spot: cilia light greyish. Hindwings light grey ; cilia grey-whitish, 
two grey shades. 
Puxjab, Multan, Ghazighat, bred September from larvae feeding 
on Populus euphratica (Indian Forest Entomologist) ; 6 ex. Nearly 
allied to the European acericina (also a poplar-feeder), but without 
the blackish apical spot and terminal markings ; also very similar 
to anthracitis Meyr. from Ceylon, w T hich however is distinct by the 
peculiarly oblique termen. 
Eucosma capnoleuca Meyr. 
Further specimens seen, bred October from fruits of Cinnamomum 
(_Z)r. L. G. E. Kalslioven). 
Eucosma xerophloea, u. sp. 
$• 12-16 mm. Head, palpi, thorax pale greyish-ochreous 
speckled grey and W’hitish. Forewings suboblong, costa anteriorly 
gently arched, without fold, termen slightly sinuate, little oblique; 
pale ferruginous-ochreous suffused whitish ; costal edge mixed dark 
grey with short oblique white strigulae; basal patch obscurely 
indicated by grey irroration and sometimes ferruginous-ochreous 
marbling, edge obtusely angulated on fold ; central fascia indicated 
by grey irroration, moderate, oblique, area beyond this more or less 
wholly irrorated grey, on costal half in $ with several oblique 
irregular ferruginous-ochreous striae; a minute blackish apical dot 
surrounded by ferruginous-ochreous; within position of ocellus 
three obscure marks indicated by two or three blackish scales each : 
cilia whitish-ochreous, base white. Hindwings 3 and 4 stalked ; 
grey ; cilia grey-whitish, two greyish shades. 
Puxjab, Multan, Ghazighat, bred September from larvae feeding 
on Populus euphratica (Indian Forest Entomologist ) ; 8 ex.
