short; pronotum not short, conical, at least the length of the 



mesonotum, or a little longer (19) Tetradadia Howard.

 stigmal, the postmarginal hardly developed; pronotum very 

 short, transverse linear.

Tribe II. ENCYRTINI. 



' The species belonging in this tribe are broad and robust, with broad, 

 stout mandibles which are broadly truncate at apex and edentate or very 

 nearly; the labrum is conspicuous; the antennae similar in both sexes, 

 the marginal vein in the front wings short, the stigmal and postmar- 

 ginal veins usually long; in the hind wings the marginal cell is long, 

 broad, and distinct, while the hind tibite have two apical spurs. 

 Only three genera are known, separated as follows: 



TABLE OF GENP^RA. 



Metathorax with the lateral ridge, or at least the metapleura, clothed with a 

 silvery white pubescence; spurs of the hind tibiae unequal, the outer one 

 being very small - - '-... 2 



Metathorax with the lateral ridge bare; spurs of the hind tibiae nearly equal. 

 Frons broad, with sparse, thimble-like jjunctures, thicker toward the scrobes ; 

 front wings with the stigmal and postmarginal veins long, nearly equal 

 in length and three or more times longer than the marginal; apical half 

 or more of the wings usually infumated. 

 Scutellum with a bunch of hairs at apex above; first joint of flagellum 

 scarcely so loug as the second. 



(23) Encyrius Latreille= Comys Foretev-^^ E^icomys Forster. 

 (Type Chrysis infidiis Rossis Comys scutellata Swederus.) 

 Scutellum withont a bunch of hairs at apex above; first joint of flagellum a 

 little longer than the second.
