tibia bifid at apex. Tarsal claws simple. Wings with the 
usual venation of Pseudomasaris ; radial cell rather long and 
narrow ; second cubital rather large, its length on the radius 
variable, often as long as the distance between the ends of 
the two recurrent veins on the cubitus ; second intercubitus 
strongly bent below the middle. Genitalia (Fig. 1 I-K) 
essentially as in P. occidentals. 
Body mostly dull, densely and fairly uniformly covered 
with medium-sized and smaller punctures (visible with a 
hand-lens). Center of the frons more coarsely punctured. 
On mesonotum and scutellum the punctures are of two 
sizes, the larger ones especially numerous over the posteri- 
or portion of the mesonotum. Puncturation stronger on 
the basal constricted areas of the first three tergites than 
on the remainder of the abdomen. The following parts are 
impunctate and shiny: most of the outer surface of the 
mandible; the median depressed area of the concavity of 
the propodeum; a median, more or less triangular area at 
the base of the second to sixth tergites; and the middle of 
the seventh tergite very extensively at the base. Pubescence 
short, but rather abundant on head and thorax, sparser on 
the abdomen ; mostly grayish, a little darker on mesonotum 
and vertex. Posterior edge of middle femur with dense, 
somewhat silvery brown pile on the under side. 
Black, with the following areas sulphur-yellow: man- 
dibles (except the long black apices) ; labrum (except the 
ferruginous tip) ; clypeus (except the upper margin very 
narrowly and minute dots in the center) ; a double spot on 
the frons above the insertions of the antennae; the inner 
orbits from the base of the mandibles to the posterior ocelli, 
filling the ocular sinuses and widening on the frons to con- 
nect with the median spots ; a small spot above each of the 
posterior ocelli; outer orbits, the yellow not reaching the 
vertex; most of the pronotum (except for a black, more or 
less triangular spot in the posterior half) ; a large spot in 
the upper part of the mesepisternum ; tegulae; a spot on 
each side of the mesonotum close to the hind portion of the 
tegula; four elongate spots over the middle of the mesono- 
tum (forming two interrupted, diverging stripes) ; broad 
hind margin and extreme sides of scutellum ; extreme sides
