above, transverse below, and closely united to the clypeal mark — all pale 
yellow. On the lower half of the front is a large mark, gradually, roundly 
narrowed below from the top, and with an incision in the centre below, 
longer than wide and slightly narrowed below ; a narrow continuous line 
on the apex of the pronotum ; a narrow line on the post-scutellum ; a 
large transverse mark on the sides of the second abdominal segment, the 
apex roundly, irregularly narrowed from the outerside to the base, the 
two marks extending close to the middle of the segment ; a narrow line on 
the apex of the second ; a slightly broader one on the third ; a still broader 
one, dilated in the middle, and one of equal width, and twice wider than 
long, on the centre of the fourth — pale yellow. The basal three joints of 
the flagellum, the apical joint, a broad line on the outer orbits, roundly 
narrowed in front, commencing on the outer half of the vertex and extend- 
ing halfway down the eyes ; the mandibles, tegulae, and the basal and 
apical segments of the abdomen, red. Legs of a similar red colour, the 
coxae, trochanters, and the base of the femora narrowly and irregularly, 
black ; the outerside of the four hinder tibiae and the tarsi pale yellow ; 
the apices of the tarsal joints red. Wings fuscous- violaceous, the hinder 
pair paler ; the radial cellule darker tinted ; the stigma rufo-testaceous ; 
the second abscissa of the radius one-half of the length of the first, and 
hardly one-fourth of the length of the third ; the first recurrent nervure 
is received at the apex of the basal third, the second at the apex of the 
basal sixth of the cellule ; the cubital nervure in the hind wings inter- 
stitial. Male. 
Length 12 mm. 
Middelburg town. 
Head and thorax closely, rugosely punctured; the vertex more strongly 
than the front and the scutellum and metanotum more strongly than the 
mesonotum. Clypeus sparsely punctured. There is a narrow, distinct, 
roundly curved furrow shortly above the middle of the mesopleurae. Eyes 
converging above, separated there by the length of the basal three joints 
of the antennae ; they are margined on the innerside and have a slight 
incision above the middle. 
The affinities of this species are with P. flavolineatus Cam., from 
Kilimandjaro ; the two may be separated as follows : — 
Two short lines on the lower part of the front ; the flagellum entirely reddish below ; 
the clypeus immaculate ; the third abscissa of radius fully one-half the length of the 
third ; the first recurrent nervure received beyond the apex of the basal third ; a 
narrow yellow line on the apex of the second abdominal segment ; the line on 
the fifth not dilated broadly in the middle, not wider than on the fourth, that on 
the fifth small and rounded at the base ; the legs without yellow. 
Flavolineatus Cam. 
A large mark, widened above, on the lower part of the front ; the flagellum only reddish 
at the base ; the clypeus with a black mark in the centre below ;-the second 
abscissa of the radius one-fourth of the length of the third ; the first recurrent 
nervure received at the apex of the basal third ; no line on the apex of the second 
abdominal segment ; the line on the fifth widened and wider than on the fourth ; 
that on the fifth large and transverse at the base ; the legs largely yellow.

Philanthus transversus, sp. n. 
Black ; the head in front below the antennae ; the yellow laterally 
continued upwards above the antennae ; the line obliquely narrowed
