W. anchorita HoJL leucogonia Hnips.) (19 a). Body and forewing pale red-brown, the white mark¬ 
ing not so mncli twisted as in the two preceding species. The space as far as the interior line greyish white 
as far as the snhmedian fold. The interior line extra-angidar at the median vein almost to the lower cell-angle, 
united at vein 1 witli the exterior line. A red-brown pear-shaped spot at the cross-vein, edged with white. 
Veins 3—5 fine white. Exterior line fine, outwards as far as vein 7, then parallel with the margin as far as 
vein 3, then strongly bent inward to the interior line. At the costal margin behind it there is a triangular white 
spot and a less intense spot at vein 2. Hindwing pale brown. 39 mm. Niger District, Gabun. Described accor¬ 
ding to 1 $ from Old Calabar. 
W. goodi HoU. (19 a). Body dark greyish lu'own. Forewing dark chocolate brown, red-brown at the 
inner margin and in the marginal area, somewhat bluish white directly at the base. Interior line fine, bluish 
white, obliquely outward from Ys costal margin to below the cell, then sharply bent round and united with 
the exterior line in the submedian fold. A large round sj)ot at the cross-vein, finely edged with white. Ex¬ 
terior line from a triangular white spot at the costal margin, slightly excurved and then united with the in¬ 
terior line. Submarginal line fine dark, inside Avith white dots, parallel with the margin. Hindwing dark red- 
l)rown. 35 mm. Niger District, Gabun, Cameroon. 
The 3 next species paler. 
W. araeogramma Hmps. (19 a). Body and forewing pale red-brown. A white line from the costal 
margin before the middle to the inner margin behind the middle. Reniform macula rather large, edged pale. 
Exterior line indistinct, double, excurved from the costal margin to vein 3, then vertical to the inner margin. 
Hindwing yellowish white. $ 25 mm. Central Africa. 
W. convergens Hmps. (19 b). Thoi'ax and forewing pale red-brown, abdomen lighter. Interior line 
white, from the costal margin near the base to the centre of the inner margin. Exterior line white, from a 
through-shaped yellowish spot at the costal margin, almost parallel with the distal margin. Hindwing yellowish 
white. The $ shows a much paler area before the interior line on the fore wing, and the hindvdng is brownish. 
30 mm. Cape Colony. 
W. oediplaga Hmps. (19 b). Body and forewing greyish ochreous, the marginal area reddish brown 
except at the anal angle, costal margin pale. A large chocolate brown spot from the costal margin behind the 
middle as far as the submedian fold, where it terminates in a dot. Its interior edge is bent inward, strongly 
excurved outside and bordered there by the fine dark exterior line, edged with white outside. Above the sub¬ 
median fold it is introangular and then excurved almost to the anal angle. Submarginal line of dark dots 
traceable. Hindwing jmle reddish brown. $ 35 mm. Rhodesia. 
W. monticola Sird. (19 b) resembles goodi. Thorax and forewing dark red-broAAui with a violet lustre. 
Interior line fine Avhite, obliquely outward as far as the median vein, where it forms an angle, then terminating 
in a bow in the submedian fold below the reniform macula. The latter is dark, somewhat triangular, basad 
to it a round spot, flown out towards the costal margin. Exterior line excurved around the cell, white, broadly 
edged with light, Avithout a spot at the costal margin, united with the interior line in the submedian fold. Sub- 
marginal line marked by the notched margin of the darker marginal area. Abdomen and hindAAung copper- 
broAvn. 5 30 mm. Cameroon. The specimen figured is the type. 
W. melanconica Bryk corresponds to monticoia in its colouring. Thorax and forewing violettish brown. 
Interior line not recognizable, but the basal area is someAvhat lighter than the median area, though AAuthout 
a distinct border. Reniform macula obliquely outAV'ard, rusty broAAii. Exterior line defined by the lighter area 
behind it. Projecting someAAdiat at the cell-angles, concave between them, from vein 2 vertical to the inner 
margin. Exterior half of the marginal area not violet but purely red-broAAUi. Abdomen and hindAAung copper- 
broAAui. $ 35 mm. Cameroon. 
W. pyridimacula Gaede (19 c) is someAvhat similar to araeogramma. Body brownish white. ForeAving 
light broAA'ii, AAuth a violet lustre in the basal and marginal areas, not violet at the inner margin beloAV A^ein 1 
at the base. Interior line Avhite, from costal margin undulate to behind the middle of the inner margin, 
very light before it in the loAA’er part. The ring-macula is a black dot, the reniform macula pear-shaped. Ex¬ 
terior line Avhite, stronger at the costal margin, shaped as in araeogramma. Submarginal line marked by a 
few dark dots. Bronze broAvn behind it at the margin. Hindwing white. 22 mm. East Africa. — We figure 
the type. 
13. Genus : Trogobriga Hmps. 
A small dark broAAUi insect Avith black markings forms this genus. In its contours it resembles the geniis 
Acripia, but the foreAAung exhibits a small dent of scales at the anal angle. Veins 7 + 10 -j- 8 + 9 stalked. 
Thorax AAuthout tufts, the abdomen with 3 small ones at the base. Only one species. 
T. albifera Hmps. Body and wings dark broAAUi. Interior line black, sharply outward from costal 
margin to the median vein, then obliquely inward almost to the base. A small AAdiite, black-edged spot at 
the costal margin near the apex. Traces of a dark submarginal line, edged Avhite outside from vein 3. Hind- 
Aving AA’ithout markings. $ 24 mm. Uganda. Founded upon 1 $ from Entebbe.
