212 Timehri. 
Female. Yellowish-ferrugious, the clypeus, pleure, sternum, post 
scutellum, 2 lines—broad, curved and narrowed above—on the metanotum. 
the apices of the abdomina segments, the base of the 2nd more broadly and 
the ventral surface, yellow; the following parts are black: the mandibular 
teeth, a line round the upper part of the occiput extending on to the vertex 
joined to the upper part of the eyes by a broader, oblique band, a large 
mark on the vertex and front, roundly narrowed in the centre behind, this 
part being a little wider than the 2 lateral ; shortly below the ocelli the mark 
bifurcat>: int» 2 broad branches which become narrowed below and extend to 
the antenne ; an irregular triangular mark on the upper part of the propleure, 
3 broad lines on the mesonotum the central widened at the base, for the rest 
slighly narrower than the lateral, a wide mark, widened towards the apex, in 
the middle of the scutellum narrowly, a wide line down the centre of the 
metanotum, narrowed at the extreme base, the rest of the basal half roundly 
widened, a somewhat triangular mark on the base behind the wings and a 
narrow line across the apex of the metanotum. Antenne reddish yellow. 
Legs coloured like the body, the 4 front coxe and trochaniters yellow ; the 
apex of the hind tibie and of the joints ef the hind tarsi fuscous. Wings 
hyaline, the costal cellule in front and at the apex tinged with rufo-fulvous, 
the radial cellule slightly smoky ; the stigma and nervures testaccous, the 
former more rufous in tint ; he basalabseissa of radius as long as the following 
2 united, the 2nd about one-third of the length of the 3rd, and as wde as the 
space bounded by the recurrent neryures. Ocelli small, the hinder separated 
from each other by a less distance than they are from the anterior and from 
the eyes by 3 times the distance. Malar space fully longer than the 2nd 
antennal joint. Apex of pronotum bluntly rounded, the sides bluntly rounded 
the pleural part straight, oblique. Scutellum with a shallow furrow in the 
middle. Apex of posi-scutellum bluntly rounded ; it is obliquely narrowed 
laterally at the base, and has a straight sharply oblique slope. 
The male is similarly coloured, the abdominal petiole is longer and more 
slender, not with the apical half nodose as in the F ; in it the black markings 
of the Female are paler, on the abdomen the greater part of the segments are 
fuscous, not rufo-testaceous ; the lateral metanotal marks may be absent. 
Polybia pallipes, Ol. 
Five males I can, in the meantime, only refer to P. pallipes, Ol. sec. Saus. 
They want the bifurcated spot on the head found in the type and in var. 
centralis, Cam. The front and the vertex in the middle are fuscous to rufous ; 
the mark on the front may be deeper tinted laterally, giving an indication of a 
bifurcation. The Ist abdominal segment is as long as the 2nd ; it is narrowed 
at the basal fourth ; from there it becomes gradually widened to the apex. 
The apex of the clypeus becomes gradually obliquely narrowed to a sharp 
point. Malar space almost obsolete. Ocelli separated from the eyes by about 
4 times the distance they are from each other ; the hinder from each other 
by a less distance than they are from the eyes. The 9 or 10 basal joints of 
the flagellum are for the greater part reddish brown—Ist abseissa of radius 
slightly less than the 2nd and 8rd united ; the 2nd is about one-third longer
