POLYPTYCHUS. By Dr. M. Hering. 
a curved darker olive line. Apex dark yellowish-olive. Hindwing blackish-brown, with a dark spot at the 
tornus and dark fringe-dots at vein 2—3, under surface yellowish-olive, base rather grey, with 5 transverse 
lines. Cameroon. 
affinis. P» affinis R. <£■ J. (63 c) differs from pygarga in the following parts: head and thorax with a dark dorsal 
line, forewing invariably with a dark brown subbasal dot. Hind tibiae above from the base to the apex greyish- 
white. Cameroon. 
murinus. P. murinus Rothsch. (63 c) differs from affinis in the absence of white scales at the abdominal stigmata; 
ground-colour of wings greyer similar as in grayi, the lines sharper and more distinct. Congo, Cameroon. 
lapidatus. P. lapidatus Joic. da Kaye. Smaller than the preceding species, the margin of the forewing darker 
brown, somewhat less concave, the antemedian and postmedian lines less irregular, the former ending at the 
inner margin with a brown dot composed of 2 bows. Postmedian lines feebler, hardly contrasting, only the 
spot at the tornus distinct. Anal angle of hindwing less produced, its apex broader, the brown spot at the 
tornus prolonged towards the costa. Expanse: 64 mm. West Africa, Coomassie. 
enodius. P. enodius [loll. (63 b). Forewing at the margin straight, red-brown with a dark subbasal dot, easily 
recognisable by 3 olive grey spots being situate subbasally, at the cross-vein, and at the tornus. Hindwing 
with such a spot at the tornus. Ogove River. 
falcatus. P. falcatus R. K J. (63 b). Forewing with a double subbasal dot, 2 antemedian lines and 2 or 3 post- 
median lines and a submarginal row of dots, all of which are brown, the ground mouse-coloured, the margin 
rather straight. Hindwing yellowish-grey with 3 or 4 darker indistinct transverse lines, the extreme line at 
the anal angle extended in a sooty black streak. Mashonaland and Spanish Guinea. 
cymatodes. P. cymatodes R. da J. Similar to falcatus , larger, antennae shorter and neater; fore wing more falciform. 
antemedian lines more broken on the veins; spaces between the discal lines filled with dark, thus forming a 
broad band which is strongly indented on the proximal side on the veins. Tornus of hindwing more projecting. 
Expanse: 80 mm. Nigeria, Gold Coast. 
rhadamistus. P. rhadamistus F. (63 c) is an easily recognisable species. Forewing olive brownish, centrally more 
whitish, with a very oblique brown median line, a dark subbasal dot, a brown spot before the apex and at the 
tornus. Hindwing brown with a black streak at the tornus and a blackish shadowy spot near the base. Senegal 
to Cameroon. 
boisduvali. P. boisduvali Auriv. ( = senegalensis Clark) (63 c) differs from rhadamistus in the light grey ground¬ 
colour, the undulate median transverse line and the dentate distal margin of the forewing. West Africa. 
andosus. P. andosus Wkr. (63 b). Forewing with a projecting apex, below it concave, then convex, with or 
without 2 subbasal dots, 2 antemedian and 2 postmedian lines and a shadow at the distal margin dark, otherwise 
red-brown. Hindwing brownish-red, at the anal angle whitish-grey enclosing a dark brown spot and a streak. 
$ mostly more red-brown in the forewing, $ more olive grey. Sierra Leone (German East Africa?). 
anochus. P. anochus R. da J . is separated from andosus by pinkisli-grey forewings with cinnamon-brown markings, 
the antemedian lines forming a broad band which is just as broad as the following median light interspace, 
then follows a dentate line, and from there the whole marginal area is dark and contains a series of indistinct 
grey spots. Stigma light grey, subbasal dot small. Hindwing pale brown, anal angle more produced, otherwise 
coloured the same as in andosus. Apex of forewing more produced than in the latter and in the following 
species. Expanse: 56 mm.XSierra Leone. •> 
sudanensis. P. sudanensis Clark differs from the following compar in the larger black basal dot of the forewing, the 
unicolonred tan-coloured stigma, beneath with a narrower whitish-grey marginal area and 3 distinct discal 
lines. Hindwing with 2 darker spots in the dqrk tornalarea, beneath with 2 dentate postdiscal lines. Expanse: 
50 mm. Southern Sudan. 
compar. P. compar R. da J. (63 c) is separated from andosa by the following marks: the middle and hind tibiae 
are brown, with a distinct white basal dot; forewing more reddish-grey, with but one small basal dot; stigma 
light brown in a darker ring; discal lines at the costal margin strongly curved instead of straight, margin 
slightly convex. Hindwing reddish-grey, at the anal angle shaded with blackish. East Africa. 
consimilis. P. consimilis R. da J . is very similar to compar , but the basal dot of the forewing is larger, the discal 
lines are behind less slanting, the margin not convex behind the middle. Hindwing paler, more leather-brown. In 
the nomenclatural race the forewing shows a loam-coloured cloud at the distal margin, extended somewhat 
ancylus. to the exterior discal line. Abyssinia, Atbara R. — In ancylus R. da J. this cloud at the margin is absent. 
prionites. Gold Coast. — In prionites R. da J . (63 d) the lines in the forewing are more distinct than in the other races; 
belgica. the dark margin is absent in the present in the $. L. Tsad, Uam District. — belgica Clark is lighter than 
the typical form, with a pink tint. Forewing % longer, apex more produced, the subbasal dot larger and more 
prominent, beneath the basal and apical areas are strongly contrasting. Hindwing beneath lighter. Expanse 
about 60 mm. French Congo.
