ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 297 



38. Frons convex, finely coriaceous ; scape rather short, clavate, the pedicel twice as long as thick at tip, 



longer than the first funicle joint Bseocharis Mayr. 



39. Frons not broad , 40 



Frons broad ; axillae united at inner basal angles. 



Antennae long, fusiform, luithout branches, and inserted rather high up on the face, the flagel- 



lum clothed with sparse black pile Stenoterys Thomson. 



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



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

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



Antennae with 4 branches Tetracnemus Westwood. 



41. Eyes bare, not pubescent. 42 



Eyes pubescent. 



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

 stigmal vein, flagellum hairy, without branches Habrolepoidea Howard. 



42. Antennae with five long branches 44 



Antennae with four- long branches. 



Marginal vein not thrice as long as the stigmal vein ; postmarginal vein very short or not de- 

 veloped 43 



Marginal vein about thrice as long as the stigmal vein, the postmarginal vein short ; pronotum 

 very short Tetralophiella Ashmead. 



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



the mesonotum Tetracladia Howard. 



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

 verxj short. Tetracnemopsis Ashmead. 



44. Marginal vein punctiform, not half the length of the stigmal, the postmarginal wanting. 



Pentacnemus Howard. 



Tribe II. Encyrtini. 

 The species falling in this tribe are broad and robust, the mandibles being broad 

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

 antennae 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 marginal cell is long and broad, while the hind tibiae have ttuo apical spurs. 



TABLE OF GENERA. 



1. Metathorax with the lateral ridge bare ; spurs of hind tibiae nearly equal 2 



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



spurs of the hind tibiae unequal 3 



2. Frons broad with a sparse, thimble-like 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 infvtmated ; 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 infidus Rossi). 



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



Howardiella Dalla Torre (type Bothriothorax peckhami Ashm.).
