Eyes smooth, palpi reaching well beyond frons, 2nd joint long and laterally compressed, 

 bearing adpressed scales, 3rd joint rather long, acuminate ; antennae of moderate length, 

 white ringed and with a gradually swollen club flattened apically ; fore tarsi of <J not segmented, 

 delicately spinose beneath. 



Wing -venation. Wing venation is not uniform throughout the genus. Tn undularis (Text 

 fig. 244) vein 7 on the fore wing ends on the outer margin slightly below the apex, veins 3 

 and 4 on the hind wing arise from a short common stalk. This is the position in a number of 

 species, e.g. xanthostola, evanescens, flavicans, rochei, undina, fulvicans, eukrines, homey eri 

 despecta, modesta etc. In Liptena decipiens (Text-fig. 245) vein 7 on the fore -wing similarly 

 ends below the apex, but veins 3 and 4 on the hind wing arise from a common point at the 

 lower angle of the cell, which is the condition also in alluaiidi, tulliana, tullut, o-rubrum, rubro- 

 maculata etc. The venation of albomacula, ideoides, and gordoni is identical with that of 

 Falcuna. In fatima and submacula vein 7 of the fore wing terminates at the apex. 



However, the systematic divisions which could be established on the basis of these 

 slight differences in wing venation in no way correspond with those based on the 

 characters of the <$ genitalia, which in my opinion are far more important and 

 significant. Neither do they correspond with the divisions which could more easily 

 be made on such obvious characters as colour, e.g. black and white, yellow, brown or 

 black species. For this reason I consider Karsch's Leucolepis (type decipiens) to be 

 merely a synonym of Liptena. 



Male genitalia (Text-fig. 38, Liptena undularis). Uncus crescentic with a shallow depression 

 on the posterior distal margin ; subunci long, curved and swollen midway ; tegumen oval ; 

 vinculum rather broad and produced to form a very long spatulate saccus, directed caudad and
