Genus CERATOMANSA novum 
This genus is closely allied to Mansa Tosquinet; the most 
striking differences are indicated in the following key: 
1. Frons shallowly concave, unarmed; vertex deeply concave; antenne stout, 
especially beyond middle, apex blunt; maxillary palpi very long, 
reaching far beyond apex of front coxe; notauli practically wanting; 
sternauli weak; basal carina of propodeum wanting; legs stout, hind 
tera not White annum beii.is iii ns Mansa Tosquinet. 
Frons deeply concave, with a strong median compressed horn; vertex 
nearly level with top of eye; antennee slender, barely thickened beyond 
middle, attenuate at apex; maxillary palpi barely reaching apex of 
front cox; notauli and sternauli strong; basal carina of propodeum 
strong; legs, especially the tarsi, slender, hind tarsi black with third 
and fourth joints white ...... Ceratomansa g. NOV. 
In addition to the characters given in the key, Ceratomansa 
differs from the three species of Mansa described on preceding 
pages as follows: Slenderer; head and thorax less strongly sculp- 
tured; face impressed on each side of middle; malar space not 
longer than basal width of mandible; prepectal carina complete; 
speculum partly striate; apical tarsal joint much shorter than 
third; areolet much smaller, scarcely half as long on radius 
as basal abscissa of radius, second recurrent beyond middle; 
discocubitus slightly angulate; nervulus antefurcal; postner- 
vulus strongly broken; basal abscissa of discoideus much more 
than twice as long as nervulus.
