GRACILABIAD/E. 
Acrocercops atlantis, n. sp. 
A. 9 mm. Head, palpi golden-metallic. Thorax bronzy-golden, 
shoulders purplish-grey. Forewings deep orange ; a brassy-metallic 
blotch extending along dorsum from near base to •§, upper edge 
sinuate, anterior angle connected with costa by a siivery-metallic 
black-edged dot, posterior angle touching costa, posterior edge 
rather oblique and marked with some dark fuscous scales; an 
elongate silvery-metallic mark on costa before middle ; a triangular 
brassy-metallic blotch on dorsum beyond middle, reaching | across 
wing; an irregular narrow golden-metallic patch extending along 
termcn to apex : cilia grey. Hind wings rather dark grey ; cilia 
groy. 
Costa Rica, San Jose; 1 ex. Nearest trimetcilln , but in that 
species the posterior angle of basal blotch only reaches half across 
wing. 
Acrocercops hemistacta, n. sp. 
Differs from cathedrcea apparently only in forewings being rather 
darker brown, second fascia less dilated towards dorsum, fourth 
reduced to a costal dot or mark and seldom a small dorsal dot. 
Bengal, Pusa, bred from larvae feeding (sometimes 9 or 10 
together) in blotches in leaves of Achyranthes aspera {Amarcmtacece) 
{Fletcher). Formerly identified by me as cathedrcm , from which I 
now think it must be considered distinct, though extremely close. 
The example recorded from Karwar as bred from gall-mines in 
leaves of “ Kungina ” creeper {Maxwell) is very similar to this, 
but probably a new species. The form from Coorg is perhaps also 
distinct. 
Acrocercops catliedraea Meyr. 
Examples apparently nonspecific with the original captured 
Khasi Hills types have been bred at Pusa from mines in leaves of 
Ureha lobata {Malvaceae) {Fletcher). A. quadrifasciata Htaint., 
which has not been rediscovered, was bred from Urena lobata, but * 
according to his description and figure is certainly not this species, 
but a form allied to ordinatella. 
Acrocercops helicomitra, n. sp. 
S 2 • 7-8 mm. Head, thorax greyish-ochreous. Palpi smooth, 
slender, greyish-white. Forewings dark fuscous ; markings white ; 
an oblique triangular blotch occupying basal portion of dorsum, its 
apex running to costa before middle, leaving only a narrow dark 
streak along basal portion of costa ; a parallel oblique fascia beyond 
middle, connected with preceding on dorsum, its costal end 
irregularly produced towards apex ; two narrow bars or pairs of 
spots towards apex, anterior more or less connected dorsally with
