may be distinguished from Lupparia by the absence of an inter- 
calated apical triangle to the wings. Consequently Pseudectobia 
sinks as a synonym of Lupparia which may for the present at 
any rate be considered as separate from Liosilpha. The following 
species may be referred to Liosilpha: 
L. pumicata Stal (Brazil). Type of the genus. 
L. japonica Shelf. (Japan). 
L. alluaudi Shelf. (Madagascar). 
L. latipennis Br. (Ceylon) and the species described below. 
Lupparia includes L. adimonialis Wik. (Philippines), L. insularis 
Sauss. (Mauritius). 
Liosilpha bicolor sp. n. (Plate Il fig. 5.) 
2. Flavo-testaceous, nitid, rather convex. Head with eyes 
rather close together, a castaneous band between them; antennae 
with basal joint testaceous, remaining joints castaneous shading 
to rufous. Pronotum trapezoidal, posteriorly very obtusely angled. 
Tegmina extending slightly beyond apex of abdomen, marginal 
area very broad, 10 costals, the last 2 or 3 ramose, discoidal 
sectors oblique, posterior ulnar simple. Wings hyaline suffused 
with flavo-testaceous, mediastinal vein 3-ramose at apex, 10 costals, 
ulnar vein 9-ramose, no triangular apical area, 1° axillary 3- 
ramose. Abdomen castaneous above, paler at base, supra-anal 
lamina produced triangular, rufous; abdomen beneath castaneous, 
the sternites posteriorly and laterally margined with testaceous, 
sub-genital lamina semi-orbicular, not very large, rufous. Cerci 
of 14 joints, elongate, acuminate, fuscous tipped with testaceous. 
Femora and coxae testaceous, tibiae and tarsi castaneous; front 
femora with a complete row of spines on anterior margin beneath, 
formula of apical spines ?, +, +, no genicular spines on front 
femora. 
Total length 17 mm; length of body 14 mm; length of 
tegmina 14 mm; pronotum 4,9 mm >< 7 mm. 
1 2, Cameroons (Conradt). 
The bicolorous legs and banded abdomen render this a con- 
spicuous species. A male also from the Cameroons is in the 
collection of Senor Ign. Bolivar, it resembles the female but 
the supra-anal lamina is strongly produced, slightly exceeding 
the sub-genital lamina which is asymmetrical and provided with 
an unequal pair of styles, the right being flattened and short, 
the left long, strongly chitinised and sharply pointed; the edge 
of the lamina is grooved to receive these styles.
