38. Frons convex, finely coriaceous ; scape rather sliort, elavate, tlie i)e<lieel twice as loni; as thick at tip, 



longer than the first funicle joint Bseocharis Jlayr. 



39. Frous not broad 40 



Frons broad ; axilla; united at inner basal angles. 



AntennjB long, fusiform, without branches, and inserted rather hijili up on the face, the llagel- 



lum clothed with sparse black pile Stenoterys Thomson. 



Antenna; with 4 branches, a branch on joints 1 to 4 of funicle Tetracnemoidea Ashmead. 



40. .Vxilhe united or touching each other at their inner basal angles ; anteunic either simple or ramose 41 

 Axillic either widely separated or at least not touching each other at their inner basal angles. 



Autennie with 4 branches Tetracnemus Westwood. 



41. Eyes bare, not pubescent. 4'2 



Eyes pubescent. 



Marginal vein a little shorter than the sligmal, the pustniarginal vein at least as long as the 

 stigmal vein, flagellum hairy, ivithout branches Habrolepoidea Howard.' 



42. -Vntenna; with jive long branches 44 



-Vntennic with four long branches. 



Marginal vein not thri(^e as long as tlie stigmal vein ; po^t marginal vein verij short or not de- 

 veloped 4;! 



Marginal vein about thrice as long as tlie stigmal vein, the pustmarginal vein sliml ; prunutuni 

 very short Tetralophiella Ashmead. 



43. Marginal vein only a little longer than the stigmal ; pronotum not short, conical, at least as long as 



the mesouotum Tetracladia Howard. 



Marginal vein only about thrice as long as thick or about half the length of the stigmal ; pronotum 

 very short Tetracnemopsis Ashmead. 



44. Marginal vein punctiforni. not half the lengtli of the stigmal, the postmarginal wanting. 



Pentacnemus Howard. 

 Tkibk II. Evcijrthii. 

 The species liilliug in this (ril)e are lii-oad and rulmst, the inaiidil)les Ijeiiig liruad 

 and stout, truncate at apex, and edentate or nearly ; tlie labniiii is conspicuous; the 

 antenna' are very similar in both sexes; the marginal vein in the front wings is 

 short, the stigmal and postmarginal veins being usually long; in the hind wings 

 the mai-ginal cell is long and broad, while the hind tibite have hro apical spurs. 



TABLE OF GENERA. 



1. Metathorax with the lateral ridge bare ; spurs of hind tibite nearly c<iual 2 



Metathorax with the lateral ridge or at least the metapleura clothed witli a silvery white pubescence ; 



spurs of the hind tibiie unequal 3 



2. Frons broad with a sparse, thimliU-likc punctuation, thicker towards the scrobes ; stigmal and post- 



marginal veins long, nearly equal in length and three or more times longer than the marginal ; apical 

 half or more of front wings usually infumated ; scape long and slender. 



Scutellum with a tuft of long hairs towards apex ; first joint of the flagellum hardly so long as 



the second Encyrtus Latreille (type Chrysis injidua Rossi). 



Scutellum ivithout a tuft of long hairs ; first joint of the flagellum a little longer than the second. 

 Howardiella Dalla Torre (type Botliriolhorax pcchhumi .\shm.).
