Ceropales ligea, sp. nov. 
$ . Black, the clypeus, a spot in the emargination of the eyes, a narrow line behind 
them, the anterior angles of the prothorax, a line on its posterior margin, the postscutellum, the 
posterior lateral lower angles of the median segment, a spot on the front of all the coxae, the 
apex of the femora of the anterior legs behind, the apex of the femora of the intermediate legs 
in front, a line broadly interrupted in the middle on abdominal segments one to four and the 
whole of the sixth segment above ivory white, the tibiae and basal joint of the tarsi of the 
anterior legs testaceous red with a line of black above, the femora except at the extreme apex of 
the posterior pair of legs blood red, the calcaria of all the legs except the inner one on the 
posterior legs ivory white ; wings clear hyaline, slightly fuscous towards their apical margins. 
Head, thorax, and abdomen shining with a silky lustre, very minutely rugulose. Antennae dull 
black, setaceous, the scape and basal joint of the flagellum in front ivory white.

In a collection of Burmese Hymenoptera, which I have not yet worked out, there are two

$ . Head, thorax, and abdomen black, a spot at the base of the mandibles, the clypeus, a 
triangular spot above it, the sides of the face, a short line on the scape in front, a small spot 
behind the eyes, a line broadly interrupted in the middle on the posterior margin of the pronotum, 
the postscutellum, a spot on the anterior upper angles of the median segment, a larger tri- 
angular spot on each side of the apex of the same, the femora and tibiae in front and the basal 
joint of the tarsi of the anterior and intermediate legs, the coxae above, a line on the femora and tibiae 
in front, and the basal joint of the tarsi of the posterior legs, a fine line broadening laterally 
along the margin of the third abdominal segment above, a triangular spot on each side of the 
second ventral segment and a quadrate spot on each side of the third ventral segment bright 
lemon yellow ; wings hyaline, shaded with dark fuscous along the costal margins of the fore- 
wing. Head, thorax, median segment, and first abdominal segment somewhat coarsely

The punctures are partly effaced on the clypeus and face in front. Head broad, broader than 
thorax, inner orbits of the eyes nearly parallel, a sharp short vertical carina between the antennae ;
