Charterqus chartarius, Oliv. 
Saussure, Etudes sur 1. Fam. d. Vespides, II, 220, Pl. XX XI. f.4. 
Chartergus apicalis, Lep. 
This species is a close mimic of Polylia atra, Ol. Tatua morio, F., is another 
wasp with the same type of colouration. 
Charterqus trichiosomus, sp. n. 
Black, densely covered all over with white pubescence, which is longer 
and less dense on the abdomen than on the thorax ; the face, clypeus the inner 
orbits from the beginning of the eye-incision, where it is narrowed, the yellow 
on the lower part of the incision wide, extending to the antenne, and a line 
on the lower three-fourths of the outer orbits, narrowed above, below extending 
to the outer edge and extending to the malar space ; the antennal scape testa- 
ceous below, wings hyaline, fuscous violaceous in front, the cloud filling the 
greater pait of the lst cubital and the radial cellule; the nervures black. 
Female. Length 9 mm. 
Vertex almost entirely impunctate, the front with shallow points distinctly 
separated. The front is raised, narrowed and projects between the antenne, 
where it is distinctly furrowed. Thorax distinctly but not very closely 
punctured, the puncturation almost hid by the pubescence. There is a 
narrow smooth shining line, dilated at the base and apex, down the centre 
of the apical two thirds of the scutellum. The hind legs except the coxae, 
are piceous. Mandibles brownish red. 
Charterginus pallidibalteatus, sp.n. 
Black, a moderately broad line on the orbits commencing at the eye incision, 
where it is continued on the sides of the clypeus, on the apex of which the 
2 are united by a narrower line, a line, half the width ofthe inner ones, 
on the outer orbits, a still narrower line on the apex of the pronotum and line, 
slightly narrower than those on the front of the head, on the apices of the 
basal 5 abdominal segmenis, all round except the lst which is on the top 
only, pallid yellow. Wings hyaline, the nervures and stigma black, Female 
Length 8 mm. 
Face, clypeus and temples smooth, the front and vertex moderately closely 
and strongly punctured. Thorax more strongly and closely punctured than 
the head, the lower part of propleure base and apex of mesopleure, base of 
metapleure and the lower narrowed part of the post-scutellum smooth ; 
the apical part of the metapleure is not so strongly punctured. Abdomen 
smooth, bare, semi opaque. 
Obs. Charterginus, Fox, seems to me to be a good genus. It may be known 
from chartergus by the bare eyes by the post-scutellum being narrowed to a 
point into the metanotum and by the smaller basal abdominal segment.
