The two black and red species described above are closely related 
to E. lucasia Sauss. The three may be separated thus : — 
A yellow line on the pronotum, and on the apices of the basal two abdominal segments) 
the four front legs streaked with yellow ; wings hyaline, except slightly along the 
fore margin ; the clypeus not transverse. Lucasia. 
Thorax and legs without yellow, the wings largely fulvous or violaceous, the 
clypeus transverse ; wings uniformly fuscous-violaceous, the clypeus strongly 
punctured, as wide as long ; tegulae strongly punctured ; stigma black. 
Pulchripe nn is. 
Wings fulvous, the apex fuscous, the stigma testaceous, the clypeus smooth, longer 
than wide, tegulae smooth. Svilocera. 
E. lucasia Sauss. has been taken by Mr. Janse in the Transvaal. It 
is one of the most widely distributed of the African species of Vespidae.
