I'he genus Calocerineloides Girault, male, is not included in the table. 
In the Eneyrtine, there are three or four kinds of heads: (1) The inflexed or normal 1: 
which the vertex is normally rounded, the antennal scrobes present, the ventral half of the 
face depressed, the outline of the head usually circular (cephalic aspect), the frons broad or 
narrow; (2) the kind in which the frons is prominent (from lateral aspect especially), the 
inflexion very great, the vertex flat and abruptly declivous so that from lateral aspect it forms 
the base of a more or less distinct triangle; (3) the lenticular or convex-lens-shaped head, 
characterized by the face not being inflexed, the scrobes absent or very short, the whole surface 
a regular convexity (the occiput usually a regular concavity); and (4) the head which is 
plainly longer than wide as viewed from the cephalic aspect (normal position).* 
* Like the head of an ant or a Spalangia. The frons is considered broad when the distance 
between the eyes is great or normal, the eyes wide apart and narrow when they are much converged 
so that the vertex is linear caudo-cephalad, or more or less so. A moderate frons is therefore the state 
more or less between these two extremes.
