 The genus Cdloceriiieloulta Girault, male, is not included in the table. 

 In the Encyrtinje, there are three or four kinds of heads: (1) The inilexed or normal \y. 

 which the vertex is normally rounded, the antennal scrobes present, the ventral half of the 

 face dejiressed, the outline of the head usually circular (cephalic aspect), the frons broad or 

 narrow: (2) the kind in which the frons is |u-oniinent (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; ( )! ) the lenticular or convex-lens-shaped head, 

 characterized by the face not being infiexed, tlie scrolies jibsent oi- very short, the whole surface 

 a regular convexity (the occiput usually a regular ccmcavity) ; and (4) the head which is 

 plainly longer than wide as viewed from the cejihalic as]iect (normal ]iositiou).* 



* Like the head of an ant or a Hi)ahinf/ia- The froa.s i.s considered broad when the distan»re 

 between the eyes is great or normal, the eyes wide apart and udrroir when they are much converged 

 so that the vertex is linear caudo-cephalad. or more or less so. .A luodrrate frons is therefore the state 

 more or less between these two extremes.
