the lower part of the front ; the central broader and irregular ; the latteral 
more transverse and curved, pale yellow ; abdomen red ; the basal 
segment black, except at the apex broadly in the middle ; the black lateral 
apical part projecting inwardly at the apex ; the sides and ventral surface 
largely suffused with orange yellow ; legs yellow, suffused with rufous ; 
all the coxae and trochanters, the basal half of the fore femora, the 
middle to near the apex and the whole of the hinder, the hind tibiae, and 
the basal half of the basal joint of the hinder tarsi, black ; wings fuscous- 
violaceous ; the stigma and nervures black ; the first and third abscissae 
of the radius almost equal in length and about one-fourth longer than the 
second ; the first recurrent nervure is received shortly beyond the middle ; 
the second at less than half the length of the third abscissa of the radius 
from the second transverse cubital nervure ; the area on metanotum 
closely, somewhat strongly, transversely reticulated, with a stronger keel 
running down the centre ; it is triangular, and is as long as it is wide at 
the base ; the pubescence is pale and is longer on the metanotum and 
ventral surface of the abdomen than elsewhere ; the fine furrows bordering 
the clypeus are broadly rounded at the sides above and below ; apex 
of clypeus broadly rounded ; the sides not projecting. Female. 
Length 15 mm.

Head, thorax, and abdomen at the base closely and somewhat strongly 
punctured ; the third and following segments of the abdomen with the 
puncturation weaker and becoming gradually weaker towards the apical. 
This species, of those known to me, comes nearest to P. loeflinqii Dbm., 
or what I make out that species to be. The main difference between them 
may be best shown in synoptical form. 
The yellow on the face projecting at the sides obliquely on to the front, which is 
immaculate ; the furrows bounding the clypeus forming acute angles ; the meta- 
notal area smooth and shining ; the yellow on the outer orbits ; a small oblique 
mark twice wider outwardly than it is along the eyes ; the mandibles with a small 
yellow mark ; the greater part of the scutellum and a line on the post-scutellum 
roundly narrowed behind and a longish mark on the upper half of the mesopleurae ; 
only the basal half of the first abdominal segment black, the black trilobate at the 
apex, the legs black, except for a line on the apical half of the fore femora and 
one on the middle tibiae below. Hoeflingii Dbm. 
The yellow on the face not projecting laterally on to the front, which bears three 
small yellow spots ; the furrows bordering the clypeus rounded at the angles ; more 
than the basal half of the mandibles yellow ; metanotal area reticulated, opaque, 
the outer orbits with a long broad yellow line ; scutellum with small squarish mark 
in the middle ; post-scutellum and mesopleurae immaculate ; the first abdominal 
segment black to near the apex ; the legs with the four front femora in part ; the 
four front tibiae and the greater part of the tarsi rufous-yellow. Spilaspis Cam.

Black; the head densely and, to a less extent, the thorax covered 
with white pubescence, the hair on the metanotum longer and denser 
than it is on the rest of the thorax ; the clypeus, except for a small 
squarish mark on the centre of the apex, which is prolonged laterally into 
a curved line ; on the sides is a large mark, as long as it is wide above, the 
top with a rounded incision on the innerside ; it is narrowed below and 
is separated from the lateral projection by a narrow black line narrowed 
outwardly ; above the central mark on the face is a small mark, rounde,d
