L. semiochrea Fldr. (11 e). Here the forewing is similar as in arabica, but the hindwing, on the contrary, 
is in the basal half brown, in the distal portion yellow. Smaller than arabica. Natal. 
L. pandula Bsd. (= trimenii Fldr., limbata Btlr.) (11 e) looks almost exactly like a Pseudlepista atrizona 
(9 h), but the black marginal band in the apical part of the forewing is not so broad. The name of the genus 
,,Pseudlepista“ alludes to this resemblance. From the Cape of Good Hope to East Africa *). 
55. Genus: JPoliosia Hmps. 
To this genus being otherwise purely Indo-Australian and having been dealt with in Vol. X, p. 218, 
also 2 West African forms are reckoned, both of which are very small and insignificant. 
P. albida Hmps. (11 e). Body and both wings quite uni-coloured pale ochreous. From Gambia. 
P. nigrifrons Hmps. (11 e). Expanse the same as of albida : 18 mm. Colouring of $ the same, but 
with a black frons and base of the costa. $ with a dark grey abdomen and hindwing. On the Niger and in 
Camero on. 
56. Genus : Tigrioldes Btlr. 
This genus, all the (20) forms of which except two live in the Indo-Australian Region, is characterized 
in Vol. X, p. 214. 
T. termineola Hmps. (Ilf) is orange, with paler hindwings, the forewing with a dark brown marginal 
band. Ashanti. 
T. quadrinotata Wkr. (= bipunctigera Hmps. nec Wallgr.) is scarcely noticeably smaller, likewise 
orange; forewing without the marginal band, but with 2 dark dots, one in the cell-end, the other one in the 
submedian fold. Natal. 
57. Genus: Stciiilemu Hmps. 
With a proboscis. Palpi porrect, hardly projecting beyond the smooth frons; antennae finely serrate, 
with ciliary tufts. In the forewing the 1st subcostal branch already extends from the centre of the upper cell- 
wall as an anastomosis to the costal vein, the 2nd branches off far before the cell-end and goes into the costa 
before the apex, the stalk of the 3 other subcostal branches rises from the upper cell-angle with the upper 
radial. The cross-vein is feebly incurved. Vein 5 is absent in both wings. Only 1 species is known, very closely 
allied to the Lithosia and closely approaching the palearctic region. 
S. aurantiaca Hmps. almost looks like a palearctic Lith. complana (Vol. II, pi. 12 i), but the wings 
(particularly the hindwings) are broader, and the costal stripe on the forewing, and the hindwing are of a 
brighter yellow. According to Strand, one specimen of the Berlin Museum has on the lead-coloured surface 
of the forewing a dull greenish reflection, and the hindwing is not so deep orange-yellow. Although Strand 
owns that this may be the normal $ of aurantiaca, he still denominates the form ,,conditionally“ subaurantiaca , 
Abyssinia, Lake Nyassa. 
58. Genus: Crocosia Hmps. 
Separated from the preceding genus by the lower radial rising on a long stalk with the upper median 
branch. Only 1 species from the Gold Coast. 
C. phaeocraspis Hmps. (lie). Expanse 25 mm. Easily discernible by the broad black marginal 
band of the forewing, in front of which there are 2 black dots. Bibionaha, Kumasi. 
59. Genus: liepirfilciiia Hmps. 
Entirely different from the other genera by the veins. The $ has the costal margin as far as the apex 
narrowly reverted. The 2nd subcostal branch and the stalk of the three last subcostal branches anastomose, 
producing an areola. The long stalk of the last radial and 1st median rises from the lower cell-angle. In the 
hindwing 3 is forked with 4, 6 with 7, whilst 5 is absent. 1 species is known from East Africa. 
*) The species was figured in the Indian part of this work (Vol. X, pi. 14 b), owing to an erroneous statement; its 
occurrence in India is not proved and very unlikely.
