The venation resembles that of L. Thwaitesiana Westw. (Tr. 
Ent. Soc. Lond. 1876, Tab. III, fig. 6b), except that, in the latter, 
the tip of the first vein is represented as incurved towards the 
second and ending in it; the cells in the apical portion of the wing 
are not quite as long as in L. aurantiaca.

End of the first vein incurved towards the costa; marginal 
crossvein either very near its tip or removed from it. 
Wings with numerous brown spots 
Brown spots on the veins small and delicate, not nume- 
rous enough to affect the general color of the wing; 
inner end of the second posterior cell much more 
proximal than that of the third. 
R) When the marginal erossvein is at the tip of the first vein 
(L. ımponens, strigivena), a doubt may arise which alternative to take; 
in such a case both must be tried.
