round, large, over width of frons ; irons evenly rounded ; antennse bi- 
pectinate, short, a little less than J of costa of fore wing ; first joint of 
shaft with a long tuft of hair ; shaft curved ; pecten in 8 times shaft, 
getting suddenly shorter towards apex and ending in 2 long bristles ; 
in $ the antennae are only J of costa and the pecten are about 2 times 
shaft, but also ending in 2 long bristles ; frons and tegulae covered with 
moderate hair ; thorax with scales ; abdomen about length L of hind 
wing and covered with scales and hairs ; fore tibia with a process nearly 
as long as the tibia, thin, slightly curved and bluntly pointed, covered 
on the outer side with long hair ; hind tibia with 4 spurs ; femora, tibiae, 
and tarsae of all legs with long hair. 
Fore wing sub-triangular ; costa slightly hollowed out ; termen evenly 
rounded from veins 2 to 6 ; inner margin nearly straight ; apex and tornus 
rounded ; lb simple at base ; a trace of 1c ; 2 from well beyond J lower- 
median ; 3 from J 2 to 4 ; 4 from lower angle ; 5 from J distance 3 to 4 ; 
discocellular only faintly represented ; 6 from below upper angle ; 7 and 8 
on a stalk of J whole length of 7, from upper angle ; 9 and 10 on a stalk 
of over ^ 9, originating from about J of upper median ; upper J of stalk 9 
and 10 and 9 as far as § anastomosing with 8 from end of stalk 7 and 8 
for about J free part of 8, so as to form a small areole ; 11 stalked with 
stalk of 9-10, so as to come out of J of areole ; 12 almost parallel to upper 
median and vein 11. 
Hind wing nearly semicircular ; costa almost straight ; outer margin 
well rounded and with a slight lobe at veins 2 to 5 ; inner margin, apex, 
and tornus well rounded ; la rather long ; lb somewhat curved ; 2 from 
about f lower median ; 3 and 4 on a stalk of J 3 and from lower angle ; 
5 from near middle of discocellular, the upper part of discocellular faint 
and oblique ; cell a little over J of wing ; 6 and 7 from upper angle and 
on a stalk of -J- of 6 ; 8 approaching upper median at beyond but not 
touching it, then curved upwards and again downwards towards tip. p- 
The venation varies a little in the different species. In pulverea 
11 comes from beyond | the areole ; in guadripunctala 11 comes from 
nearly the end of the areole and the stalk of 6 and 7 in the hind wing is 
longer, up to ^ of 6 ; in gemmata 11 comes from the upper median, the 
areole is very small, 10 comes from § stalk of 8 and 9, 7 comes from J of 
stalk 8-9-10, while the hind wing has the stalk of 3 and 4 much longer (J), 
5 comes from J discocellular, which is more oblique, stalk of 6 and 7 is 
longer (J), 8 touches the upper median, though it does not anastomose 
with it ; moreover, the process of the fore tibia is as long as the tibia. 
It may be necessary to create a new genus for gemmata, but as it 
certainly comes very close to Lacipa, I leave it provisionally where it is. 
Species marked with an * are only known to me from description.

yellow (III) sarcistis . 
b. Fore wing with the ground colour more whitish or 
pure white 2. 
2. a. Fore wing and hind wing pure white ; terminal 
spots yellow 3.
