484 Mr. P. Cameron on 
Clypeus with a deep fovea on either side at the base and not 
separated from the face, its apex transverse; labrum pro- 
jecting, its apex rounded, Occiput sharply margined. Scu- 
tellum flat, not margined; postscutellum bifoveate at the 
base. Median segment areolated, its spiracles linear. Areolet 
narrowed at top, not quite one half the length of the lower 
side; the recurrent nervure is received in the middle; the 
transverse median nervure is received in front of the trans- 
verse basal. Antenne thickened beyond the middle, the apex 
attenuated. Legs stout, the tarsi spinose, the claws simple. 
‘The spiracles on the petiole are placed near the base of the 
postpetiole ; the gastroceeli large, deep; there are seven 
segments, the ventral keel is only on the second and third ; 
the ovipositor is short; the hypopygium is large, broad, 
rounded at the apex; the apical segment is larger than usual 
compared to the penultimate. 
Belongs by the form of the petiole to the Platyurd. It has 
the bluntly pointed abdomen of Amblyteles, with which it 
also agrees in the apical ventral segments not being retracted. 
Characteristic is the form of the mandibles, which have only 
one very small, almost obsolete tooth on the upperside. ‘The 
three central are on the median segment are clearly defined, 
the others are obsolete, but the keel on either side of the 
spiracles is distinct; the basal joints of the flagellum are 
elongated; the apex of the abdomen is broad and bluntly 
pointed; the face is flat; the occiput roundly concave ; the 
two abscisse of the basal part of the cubitus are straight and 
oblique ; a short nervule issues from the middle, 
Setanta rufipes, sp. n. 
Nigra, flavo-maculata; pedibus rufis, coxis trochanteribusque ante- 
rioribus flayis, coxis posticis nigris; alis hyalinis, stigmate 
fusco. 2. 
Long. 10-12 mm. 
Antenne black, a line in the middle of the scape and the 
eighth to fourteenth joints (except above) white; they are 
stout, flattened and dilated beyond the middle, attenuated 
towards the apex. Head black, the inner orbits, and the 
outer more broadly on the lower half, yellow; there is a 
broad mark on the lower side of the face, extending to and 
enclosing the foveee; above it is obliquely narrowed from the 
sides to the centre ; on the middle otf the elypeus is a large 
black mark, which is also obliquely narrowed above. Man- 
dibles yellow, their apex narrowly black; palpi yellow. 
Thorax black; a narrow curved line on the pronotum, 
reaching from near the base to the apex, two short lines near
