Imago. — <? and 9 . Head broad between the eyes, with dense short scales, Antennal 

 joints rather long, with about 14 pairs of pectinations, in o* filiform on the distal third of their 

 length; distal pectinations as long as the basal ones, but about half as thick, all densely ciliated, 

 the two pahs of pectinations are close to each other, gaping or diverging at the ends; on the 

 filiform tip the branches are represented by denticulations, the teeth ending in fine setas; hi the 

 9 (?)' the antennae are widely pectinated, with 14 pairs, the filiform tip is one-fifth as long as 

 the entire antennas, and only two ( ?) ether basal pectinations are present. Palpi short, not 

 distinguishable from the front, and not reaching it. Thorax stout, clothed above and beneath 

 with long hairs ending like a battledore or tennis racket. 



Fore wings long and narrow, much produced toward the appex in s , much less so in 9 ; 

 costa well arched; outer edge deeply excavated in <? , but little so in 9 . Hind wings reaching 

 a little beyond the tip of the abdomen in <? , as far as the tip in 9 . 



Venation: In most respects more aberrant than in Micrattacus; vein II, arises far beyond 

 the discal cell, and between the origins of III,, and Il 4 ; no vein II 2 . Ill, is widely detached 

 from III,, and forms an independent vein; the two discal veins of the same length, not forming 

 either a curved or oblique line; the independent (II1 2 ) and vein II1 3 and IV, very short; the 

 outer side of the discal cell (along the median vein) being situated in the outer third of the wing. 

 Hind wings with the discal cell extending to the outer third, and the veins extending from it 

 very short; the posterior discal vehi incurved and long. The minor differences from Henucha 

 are shown in the figures. 



Markings: The genus is at once distinguished not only by the narrow and very falcate fore 

 wings, but also by the singular upsilon-shaped transparent discal spot on the fore wings. On 

 the hind wings is a large discal ocellus centered with black, and surrounded with a wide black 

 circle; it is nearly obsolete beneath. Legs rather hairy, not very thick. 



The peculiar markings, especially the upsilon-like discal spot and the long narrow fore 

 wings, which are produced toward the apex to an unusual extent, as well as the unusually 

 broadly pectinated antennas of the female, and the place of origin of vein II, are the distin- 

 guishing features of this genus. The 9 antennas are so broadly pectinated, so closely resembling 

 the male in this respect, that without examination of the genitalia, it would be mistaken for a 

 male. Westwood, however, says that the female antennas are not "very shortly pectinated 

 on each side;" indeed, they are unusually long, though shorter than in the male. 



Geographical distribution. — So far as known the species are confined to Natal, or the coast 

 region of southeastern Africa. According to Rothschild, this genus is represented by four 

 species: L.delegorguei (Boisd.), L. hansali Felder, L. obscura Auriv., and L. dentata Hampson. 2 

 [L. delegorguei is the type of the genus.] 



1 1 don't understand why this female has antenna so well pectinated, if it is the same species as my male. 



2 [Strand, in 1911, described L. limbobrunnea, L. nyassam, L. tanganyikx, L. pupillata, L. luciphila, and L. delegorguei ab. vetusta.]
