4. Subfamily: Euxoinae. 
The subfamily is characterized by its spined tibiae. Claws absent. As in the preceding 3 subfamilies, 
the number of genera and species to be dealt with is also here very small. If the genera Agrotis and Lycophotia 
were united with Rhyacia, as it was done in Vol. XI, only two genera would be left vdth about 60 species. 
1. Genus: Eiixoa Hbn. 
Proboscis jjresent. Palpi erect, the second joint hairy in front. Frons vdth a truncate cone. Prothorax 
and metathorax with a broad tuft. Tibiae strongly spined. Vein 5 of the hindwing arises from the centre of 
the cross-vein and is more feebly developed. Type: decora W. V. from Europe. 
1. Antennae of A bipectinate. Pectinations moderately long. The last thii’d of the antenna serrate. 
E. longiclava Andremi belongs near ohesa Bsd. and crassa Tr. Thorax and forewing yellowish-brown. 
Interior line scarcely traceable. The narrow coniform macula edged with black, prolonged to the base. Vein 
1 fine white. Ring-macula very oblong, pointed on both sides. Reniform macula edged with black, normal. 
Black streaks beliind it between veins 3 and 7. Hindwing of dingy white, greyish-yellow in the $. 30 mm.

Ring-macula terminating outwardly into a long point, edged with white, filled with black. Reniform macula 
bordered on its basal side by a white angle, the rest black. Exterior line double, dentate. Submarginal line 
light, notched, somewhat distally convex in the centre. Margin blackish. Hindwing white, in the $ darker 
outside. 32—36 mm. East and South Africa, Madagascar, Greater Comoro. 
E. cymograpta Hm.ps. Thorax dark brown, abdomen greyish-brown. Forewing red-brown, dusted black. 
Subbasal line and interior line double, black, filled with white. Coniform macula small, its apex indicated by 
black scales. Ring-maciila and reniform macula large, edged with white. Median line faded blackish-brown, 
incurved in the cell. Exterior line double, its interior branch black, the exterior one less distinct, filled with 
white. Small dark streaks behind it on the veins. Dark sagittal spots before the margin, with white scales 
outside. Marginal line undulate, black. Hindwing white, veins and margirs red-brown. Fringe purely white. 
$ 36 mm. East Africa. 
E.microticai/mp.s. resembles segetum Schff. (Vol. Ill, p. 25, pi. 5d). Thorax red-brown, abdomen whitish 
ochreous. Forewing red-brown, tinged with white, the veins with black streaks. Interior line notched. Coni¬ 
form macula blackish-brown, edged with black, moderately large. Ring-macula and reniform macula blackish- 
brown, edged with white, then surrounded b}^ black. A bent median shadow and an indistinct notched exterior 
line. Submarginal line indistinct, pale, wdth red-l)rown spots inside. Hindwdng white. 25 mm. Assumption. 
E. subalba Wkr. (= nivalis Flor.) (5 d). Thorax and forewing greyish-wdiite with some dark scales. 
Traces of a subbasal dark line, obliquely outw'ards. Interior line dark, double, undulate, rectilinear, somewdiat 
obliquely outwards, the exterior branch more distinct. The coniform macula is rarely traceable. The ring- 
macula is a dark dot, the reniforin macula finely edged with dark, sometimes both are cpiite absent. Exterior 
line strongly notched, mostly indistinct. Submarginal line diffuse, edged lighter outside. Marginal dots black.

terior line double, undulate, strongly extra-angular above the inner margin, coniform macula small, black. 
Ring-macula and reniform macida grey, centred dark brown and edged wdth black. Ring-macula small, the 
reniform macula indistinct owing to the blackish median shadow'. Exterior line dentate, slightly excurved
