in the British Museum. As there is also a from Appan, Gold Coast in the last-named collection, much more 
similar to the Madagascar specimens than to the Nyasa type, this will perhaps prove a distinct species, hut I 
can find no significant difference, unless the build be a little more robust. 
S. trilineata Hmpsn. (2 k). Face broad and rather prominent, bright red. Antenna in the 2 strongly 
pectinate. The white lines slender, faintly denticulate, the postmedian of the hindwing more or less curved 
anteriorly and here more distally placed than the 23osterior end of that of the forewing. N.V/. to S. Rhodesia, 
also known from Angola and Congo. 
65. Genus: Tropicollesls ge7i. 710V. 
This genus is described in my unjmblished manuscript of the Geo7netridae of the ’'Voyage de Cii. Al- 
LiTAtTD et R. Jeannel”. d' unknown. $ with most of the characters of Syricollesis but with the wings (esjie- 
cially the forewing) narrowed, the colouring not green, cell of fore wing i/G wing-length, 1st median arising close 
to 3rd radial, hindwing with 2nd radial scarcely before middle of discocellular, 1st median stalked. PaljDiis 
scarcely as long as diameter of eye, with very short terminal joint; tongue vestigial; antenna very shortly 
pectinate. Tyi^e of the genus, T. alhiceris sp. n. 
T. albiceris sp. 7i. Exjjanse 21 mm. Scarcely paler than cream-buff, with some minute brown irroration; 
markings dusky brown, in ^daces mixed with l)lackish. Forewing with a weak sj^ot at base of costa; an elongate 
cell-S2)ot; lines strongest at extremities, antemedian from costa, dentate inward at median and submedian 
veins, outward behind; j^ostmedian from -3 costa, dentate outward on veins, incurved at both folds. Hindwing 
with distal margin rounded, but not quite regidarly; a jDostmedian line, rather more strongly outbent at 3rd 
radial to 1st median than on forewing, othei’wise similar. Underside slightly jDaler, the markings obsolescent. 
Kenya Colony: Taveta, 750 m, 16—21 March 1912 (Alltjaitd d’ Jeaxnel). Type in Mus. Paris. 
66, Genus: Omg»Iiacofleis Warr. 
Paljms moderate or long, with relatively elongate terminal joint. Hindtibia of G commonly dilated, 
with hair-jDencil. 1st radial of forewing connate or stalked, very exceptionally (so far as I know only in some 
divergems) just sej^arate, 1st median of hindwing generally, of forewing occasionally stalked. Otherwise with the 
characters of Syticollesis, though the colouring is generally of a less bluish green. Even after the elimination 
of that genus, Omphacodes is diversified, containing 3 sections. The first, which contains the Indian genotyj^e, 
directa Walk., comes nearest to Syncollesis.

0. purifimbria sp. 71 . (4 h). Ex2:»anse 23 mm. Face red. Pa^ms shorter than in the two following, even 
in the 9 only about 1 j/o times the diameter of the eye. G 'with moderately long, slender 2)ectinations; 9 antenna 
serrate. Postmedian line indicated by white vein-dots, accom23anied 2)i’oximally by some brown ones which 
are weak or oijsolete in the 99; subterminal line generally traceable; fringe creamy white. S.W. of Tanganyika: 
Marungu Plateau, \V. side, 7000 feet, February 1922 (T. A. B.'lRNS), 2 2^airs in the Joicey collection. 
0. pulchritacta Provt. Only the 9 known. In this the 2ial23us is a little longer than in purifimhrm 
but not so long as in pvlchrifitnhria. Larger than purifimbria, 28 mm; face more brown than red; forewing 
with a short, inwardly oblique rosy streak from 1st median to near fold; hindwing with a corres2Jonding dot 
or short dash on 1st median; fringes white. Central Abyssinia: Moraqui. 
0. pulclirifimbria Warr. (4 h) is readily distinguished by the long 25al23RS of the 9 ^^d the rosy ti23s of 
the fringes. Kenya Colony (type), 8.E. Sudan and Eritrea.

0. vivida Wair. (4h). Similar in size, sha2Je and colour to Sy7idr 07 nodes invenusta, WUgrn. and with a 
similar distribution, but easily distinguished in both sexes by the much longer 23alpus, green fringes and other 
characters. Fresh s25ecimens show white, red-edged s25ots on the abdomen, l)ut the body in this and the two 
following s23ecies seems very liable to “grease”. The tyj^e was from Natal.
