being tridentate (fig. 2, 6) while the anterior of the keels rising from the 
genal keel is absent (fig. 1). The hind coxa bears a ventral subapical 
tooth (fig. 2, d). Between the toruli and the clypeus there is a smooth 
area bounded by more or less pronounced lateral keels (fig. 1). Cameron 
has made G. marginata the type of a genus Oncochalcis. (The Entomo- 
logist p. 161, 1901), but his subsequent applkiation of the category has 
been loose and inconsistent.
