A. lanipes Hulst. Differing from eusciasta especially by the spot on costa before the postmedian lin e 
and by the different formation of the submarginal line. Forewings reddish brown, somewhat darker in marginal 
area except at costa. An inner black band below the costa, excurved at vein 2 and terminating at vein 1. Reni- 
forrn stigma black, obscured by a black mark that extends over it from the costa to the postmedian line at inner 
margin; it is oblique, with diffuse edge extending outwards to the submarginal line between vein 6—2. Median 
line fine, undulate, extending downwards from vein 3 below the spot. Postmedian line indistinct, double, 
obliquely to vein 6 then inwardly dentate. Submarginal line pale, undulate, indistinct between veins 6—3. 
Hindwings as in eusciasta. One $ from the Key Islands. 
2. Central tibiae of obese and w i t h brush of hair. T h e first segment 
of central tarsi without hairs, hind tarsi only with hairs at upper extreme. 
A. mezentia Cram. (= lugens Wkr.) (52 e). The species can be recognised by the very large white apical 
spot on the dark hindwings. Forewings olive-brown and brown-grey. Median area, apex, and lower part of 
outer margin, white-grey. Antemedian line distinct, vertical, outlining the dark basal area. At disco-cellular 
2 dark spots. Median line distinct, somewhat dentate, somewhat outwards to the lower angle of cell, inwards 
to vein 2, then vertically. Proximally whitish, distally olive-brown or grey-brown to the distinct white post¬ 
median line; the latter proceeds outwards to vein 6 then inwards, dentate. Submarginal line white, undulate. 
mezentinodes Strd. Median area ochreous brown, also the postmedian line. — medioalba Strd. Median area 
white, contracting to a point on the inner margin. reversa Wkr. (52 e). Forewings completely dark, with 
greenish white scales in centre. Only recognisable by the hindwings. 45—55 mm. Ceylon. — The larva is olive- 
grey with numerous longitudinal lines and a pale lateral band. Ventrally rose. On final segment with two 
yellow warts. Head yellow. Food plant, Canthium. 
A. simplex Wkr. (52 e). This species of which apparently hitherto only one $ was known, that is in 
Oxford, is recognisable by the white hindwings that are faintly brownish at inner margin. Outer margin is 
widely brown with a white spot on the margin behind the cell. Further a small white apical spot and a short 
streak from vein 2 to the anal angle. Forewings pale red-brown, somewhat lilac in median area. Antemedian 
line fine, regularly excurved widely in the centre. A spot at lower end of disco-cellular. The dentate postmedian 
line angidated at vein 6, normal. I have a $ specimen before me in which the submarginal line is not discernible. 
Somewhat paler at margin and also distally of the postmedian line. 50 mm. "Morty” and the N. E. Celebes. 
A. serva F. (52 d). This and the following species are probably a single species. On the other hand one 
can subdivide serva into 3 species according to E. Prout: in rnercatoria, which shows exactly the same forms, 
a subdivision has not been made. Forewings pale red-brown, antemedian line dark, undulate. Reniform stigma 
with fine dark outline and dark spots. The fine undulate median line somewhat excurved behind the cell, some¬ 
what inwards on the submedian fold. The outer line somewhat more distinct, parallel to median line. Marginal 
area darker brown with pale dentate submarginal line. Hindwings dark brown, somewhat paler at base, with 
interrupted white median band and the 3 usual marginal spots. purpurascens Strd. Forewings lilac-red- 
brown. — According to E. Prout most of the 'purpurascens are actually — ministra Prout. Markings and colour¬ 
ation as in purpurascens, but the fringes of forewings paler than in serva from apex to vein 2. On hindwings 
median band is somewhat narrower, the white apical spot smaller. This form occurs in New Guinea and the 
Key Islands. — fuscosuffusa Strd. Forewings suffused with black-brown, grey apical spot at costa. undata 
Strd. Forewings with black spots on antemedian line, in outer area of central field, and in the middle of outer 
area. - pentasema E. Prout (52 f) is said to be the form that Hampson illustrated in his catalogue Vol. XII, 
p. 521. This has all the 3 lines mentioned in undata double. However, in the description of pentasema, this is 
not mentioned but it is only stated that on hindwings all 5 spots are distinct, the one over the anal angle being 
brighter and still clearer than the others. New Caledonia, Fiji Islands. — Besides this I have specimens before 
me in which the forewings are pale red-brown and almost devoid of markings. Margin dark red-brown to some¬ 
what inwards of the discernible submarginal line. On costa the last third is paler. 60- 75 mm. Distributed 
from India to Australia and the Pacific Islands. Also once found on Madagascar. 
A. rnercatoria F. (52 f) might be described as a small serva. Colouration and markings vary along similar 
lines. On forewings the submarginal line of serva is replaced by a simple or double row of dark dots, which may 
also be absent. On hindwings the base is paler, the pale median band is occasionally not interrupted. As the 
species also occurs in Africa, it is dealt with in all its forms already in Vol. XV, p. 235 and pi. 27 f. It is found 
in India, Ceylon, Malacca, Java. — The larva is pale and dark lilac and olive-grey with a number of dark lilac- 
brown spots. On the fourth segment there are 2 lilac-brown dorsal spots. On the eleventh segment 2 ochreous 
brown warts. The first pair of ventral legs are stunted. Food plant, Ricinus communis. 
3. Central tibiae of ^ witho u t a brush o f h a i r. 
A. melicerta Dry. (- tigrina F., traversii Fered., ekeikei B.-Bak.) (52 f). The species is said to have 
formerly been described by Linne under janata, but we are retaining the usual name. Through the variation
