17. Genus: Tliyrogonia Hmps. 
This genus contains but 1 unmistakable West-African species. In contrast with the preceding genus 
the subcostal vein of the forewing has only 4 branches, the 1st branch rising near the base of the stalk. 
Th. efulensis Holl. (5 d) is sooty black with a blue reflection, the disc of the wing being lighter; in efulensis. 
the cell of the forewing there is a small white square spot. Cameroon. 
18. Genus: Ag>isa W/cr. 
This genus is composed of about 20 rather closely allied forms representing a somewhat clumsy 
type of Syntomis ; the colouring is without any metallic gloss, dark, the light yellow belts of the abdomen are 
mostly hazy or entirely absent, the hyaline spots rarely very light and rather indistinctly defined, sometimes 
blurred. Proboscis stunted or entirely absent, the antennae in the <$ with long pectinations, the body much more 
roughly haired than in the Syntomis, the whole habitus rather denoting nocturnal habits, somewhat arctoid, 
hindwing in the <$ often remarkably small. —- The genus forms a distinct transition from the Syntomis to 
the following Balacra. 
A. comiexa Wkr. (6 a) still has the large white central spot in the forewing and hyaline hindwings connexa. 
bordered with black as Thyr. efulensis (5 d), but the metal gloss is absent, and on the body the shoulders 
and abdominal sides are broadly orange. From Fernando-Po. 
A. crenophylax Holl. (6 a) still looks entirely like a Syntomis. The 5th abdominal ring is orange; the crenophy- 
wings are quite purely hyaline, in the forewing only the apex, a ray from the cross-vein to the margin, and lax - 
the base of the hind-margin are black, in the hindwing only the costal margin. Cameroon. 
A. sjoestedti Aur. (6 a). Abdomen still abundantly orange-banded; wings dark brown, forewing with sjoestedti. 
a small white spot in the cell and some very minute spots in the distal area; in the centre of the submedian 
area there is a yellow transverse bar. Hindwing with a very small central spot. —- In ab. homopunctata Strd. homopunc- 
the spot above the centre of the hind-margin is white instead of yellow, and the light abdominal rings are tata - 
only indicated. —- Cameroon. 
A. kucogastra Holl. (6 a). Apex of abdomen red, forewing with 4 white spots arranged like the Sou- leucogasira. 
them Cross. Congo Land. 
A. chrysopyga Plolz (6 a) is entirely like leucogasira, but the spots on the forewing are much smaller, chrysopyga. 
the spot above the centre of the hind-margin scarcely the size of the prick of a needle; hindwing blackish- 
brown with a fine small central spot. — ab. ruficilla Strd. are lighter red specimens with larger, not hyaline ruficilla. 
spots on the forewing. —- Cameroon. 
A. kerri Holl. (6 a) is quite similar to leucogasira ; the spots on the forewing are smaller, from the base kern. 
of the hindwing white rays proceed. Cameroon. 
A. lamborni Rothsch. (6 b) is smaller than the preceding, body and wings quite dark brown, also the lamborni. 
abdomen without any yellow. Forewing with 4, hindwing with 1 minute dull punctiform spots. Nigeria. 
A. tristigma Mab. Size of aurantiaca (6 c); dark red-brown, thorax marked orange, and abdomen with tristigma. 
Qrange dorsal spots; forewing with 3 or 4 orange spots similar to sjoestedti, hindwing only with traces of 
spots. Sierra Leone. 
A. albimacula Hmps. (6 b). Dark red-brown; forewing with 4 or 5 large oval white spots, an obso- albimacula. 
lete basal spot below the cell; in the hindwing the $ has a whitish costal area and an oval white central 
spot. Uganda. — In ab. mabira Strd. the subbasal spot of the forewing is blurred, the other spots are smal- mabira. 
ler, and there is no reddish spot above vein 7. 
A. endoxardha Hmps. (6 b). Forewing almost exactly as in albimacula, but hindwing with a large, endoxantlia. 
orange-tinged hind marginal spot at the base. Uganda. 
A. metarctioides Hmps. (6 b). Spots similar as in the two preceding, but the ground-colour of the metarctioi- 
forewing at the margins with a bright fiery red tinge, hindwing whitish with a ruddle-red margin and apex. dcSm 
Uganda. 
A. paraclioria Holl. (6 b). Similar to the preceding, smaller, the colouring lighter red, ground-colour paraclioria. 
only yet darkened in the surroundings of the much larger spot before the centre of the marginal area. Hind¬ 
wing white, outside ruddle-red. Cameroon, Congo. It was described as ,,Anace u and has recently been placed 
to Metarctia. 
A, monotica Holl. (= deannulata Strd.) (6 c) is much smaller than the preceding species. Forewing monotica. 
greyish ruddle-red, in the centre a large dingy white spot. Hindwing whitish with a reddish-grey apex. — quadrima- 
In the form quadrimaculata Zerny the spot on the forewing is split in two pai’ts. Congo. culata. 
A. aurantiaca Rothsch. (= palaemon Drc.) (6 c). Like monotica, but the forewing of a brighter yellowish aurantiaca. 
red and without the central spot; also the abdomen is orange. Cameroon, Congo. Allied to the following.
