7S PERCY SLADEN TRUST EXPEDITION. 
triangular incision ; the apex is fully four times as wide as the base; claws large, 
stout, as long as the last joint. The third joint of the antenne is slightly, but distinctly, 
longer than the fourth. Both the recurrent nervures are received before the middle of 
the cellule, close to each other; the second abscissa of radius distinctly shorter than 
the third—about half its length ; the apical is almost straight, with only a very slight, 
oblique slope. The sides of the metanotum, from the spiracles, are keeled, the keel 
going round the apex. The abdomen is shorter than the thorax, narrowed at the 
base and apex. 
It is not unlike the widespread Oriental WN, subtessellata, Sm.; but may be at once 
known by the stouter, reddish tarsi, with long and stouter spines, by the shorter 
abdomen and differently coloured wings. 
19. Notogonia rufo-femorata, sp. nov. 
Black ; the anterior femora slightly in front, the four posterior, the apex of the tibiee, 
and the basal joints of the four hind tarsi, red; wings fuscous violaceous, iridescent, 
the nervures black. ¢. 
Length 10 mm. 
Localities. Seychelles, Mahé (H. P. Thomasset). 
Lower part of front, face, and clypeus densely covered with silvery pubescence. 
Clypeus keeled in the middle; on the apex, on either side of the central third, is a 
minute tubercle. Eyes distinctly converging above, separated there by slightly more 
than the length of the third antennal joint. The third antennal joint is distinctly - 
shorter than the fourth. Metanotum alutaceous, keeled down the middle from the base 
to the apex, the apical slope has a distinct furrow and is irregularly striated at the apex. 
Pygidium closely punctured, covered with a silvery pile, its apex broadly rounded. 
Tibize and tarsi stoutly spinose ; the base of the fourth joint of the hind tarsi one-third 
of the length of the apex, which is roundly, somewhat deeply incised ; the pile on the 
underside is pale golden; the claws dark piceous, not quite so long as the joint. Both 
the recurrent nervures are received distinctly before the middle; they are separated 
by slightly more than the length of the second abscissa of the radius, which is about 
one-third of the length of the third ; the apical abscissa is straight, with a distinct, oblique 
slope. In fresh specimens the silvery pubescence would be probably dense. 
20. Notogonia mahensis, sp. nov. 
Black, the wings light fuscous, the nervures black; the metanotum finely, distinctly 
transversely reticulated, 7. e. the transverse striz are stronger than the longitudinal ; 
the apical slope is distinctly reticulated above, the rest somewhat strongly transversely 
striated; the metapleurze stronger, closely, regularly striated ; above the middle of the 
mesopleuree is a distinct, slightly curved furrow. ¢. 
Length 9 mm. 
Localities. Seychelles, Mahé (ZZ. P. Thomasset). 
‘The head is unfortunately missing, but the length of the metanotum and the pubescent 
pygidium show that the species is a Notogonia; and the claws, too, are long as in
