Vinsonza. 279 
VINSONIA, Szgnoret. 
Vinsonia, Sign., Ann. Soc. Ent. Fr. (5), Vol. 11. p. 33 (1872). 
A monospecific genus. Distinguished from Cevoplastes (to which it is 
closely allied) by the extension of the waxy test into prominent marginal rays. 
Newstead gives the articulation of the cephalic lobe as a generic character ; 
but this condition is approached in some species of Cevof/astes, notably 
C. rubens—in old examples of which the cephalic lobe is sharply demarked 
from the remaining parts.
