A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 119 



scales ; hyaline patches edged first with dark brown then with highly lustrous scales ; well 

 marked, postmedial fascia from apex to three-fifths inner margin, bent inwards just before costa, 

 edged distally with highly lustrous scales ; terminal row of interneural, highly lustrous dashes ; 

 fringe dark reddish brown, tipped with black at apex and at middle of wing but with white 

 elsewhere. Outer margin of hind wing strongly convex anteriorly ; concave between Cu 2 and 

 anal margin. Ground-colour of hind wing chiefly brownish orange, but orange anteriorly ; 

 speckled with black, brown and highly lustrous scales between antemedial fascia and outer 

 margin of wing ; antemedial fascia double, continuous with postmedial fascia of fore wing, dark 

 reddish brown (black at anal margin in one paratype) edged proximally and distally with highly 

 lustrous scales ; terminal row of highly lustrous dashes ; fringe dark reddish brown, tipped with 

 white near anal margin of wing. 



Under surface of fore wing orange proximally, brownish red between end of cell and outer 

 margin of wing ; lightly speckled with black between postmedial fascia and outer margin. 

 Trace of anterior part of postmedial fascia. Mind wing orange, suffused with brownish red near 

 outer margin ; lightly speckled with black distally. Small black discocellular spot. 



o* genitalia (Text-figs. 191-193) : valve with two basal processes, unequal in length ; 

 aedeagus with single, hooked cornutus ; posterior margin of eighth sternum as in figure. 



$. Unknown. 



Measurements. A.P.R. : o". Not known (no complete antenna). Wing : q*. 13-5, 

 130-140 mm. (3). 



Discussion. Separated from the closely related viettei by the slightly convex 

 outer margin of the fore wing, and in the genitalia by the differently shaped processes 

 of the valve and the presence of only one cornutus on the vesica. The variation in 

 the colour of the antemedial fascia on the hind wing is dealt with above. 



Distribution. Known from central and east Madagascar. The range of this 

 species overlaps that of viettei.

Crocinis viettei sp. n. 



(Text-figs. 194-196 ; PI. 12, figs. 317, 318) 



Description. <$. Head and palps reddish buff, reddish brown (holotype), grey-brown or 

 nearly black. Upper surface of antenna! shaft brownish buff (holotype) or buff. 



Thorax and abdomen dull orange (holotype), yellow, brown or almost black dorsally ; similar 

 in colour to adjacent surface of wing. Ventral surface of thorax and abdomen buff (holotype) or 

 brownish buff. Legs buff, but front surface of fore leg brownish buff (holotype) or brown. 



Costa of fore wing slightly convex (holotype) or straight, except at apex and base (Plate 12, 

 figs. 317, 318) ; outer margin straight except at apex of wing. Colour-pattern of wings as for 

 prolixa. Coloration of upper surface variable (see Discussion). Upper surface of fore wing of 

 holotype reddish brown lightly speckled with highly lustrous scales, the latter concentrated at 

 apex and along costal area. Ground-colour of hind wing as for fore wing, speckled with highly
