NO. 1202. GENERA OF THE ENCYRTINJB—ASHMEAD. 347 



long as thick, the postmarginal never well developed, 

 although acnminate and longer than the short marginal. 

 Flagellum filiform, pilose, the joints of fimicle ahout twice as long as thick; 

 lateral ocelli at least their width from eye margin. 



(70) ApMdtncyrtus Ashmead, new genus. 



.51. Scutellum neither triangular nor acute at iipex 51 



Scutellum triangular, acute at apex. 



Anteunai simple, subfiliform, pubescent (71) Choreia Westwood. 



52. Funicle 6-jointed - 53 



Funicle 2-jointed, the club unusually long and cylindrical (teste Mayr). 



(77) Habrolepis Forster. 



53. Head with vertex antero-posteriorly broad, the face much indexed, the frons 



regularly punctate ; antenme with the scape and flagellum 

 usually strongly compressed, broad ; wings fuscous or 



with fuscous rays 54 



Head always semiglobose, the face less distinctly inflexed, the scrobes always 

 forming a semicircle; antenme simple, filiform, the joints 

 long, cylindrical, distinctly separated and hairy, rarely 

 slightly compressed ; wings usually fusco-radiate or partly 

 fuscous, rarely entirely hyaline. 

 Scaiie elongate, extending to or beyond the middle ocellus, the flagellum 

 very long, clothed with rather long hairs. 

 (72) Cheiloneiirus 'Westwood = Sterrhocoma Forster, male. 



54. Wings fuscous, with narrow white tixis 55 



Wings hyaline, the marginal vein rather long, stoat, as long as thestigmal vein, 



the latter not short, the postmarginal not developed; 

 antenme long, filiform, the flagellum with si^arse moder- 

 ately long hairs; funicle joints 1-6 constricted at apex or 

 subpedunculate, somewhat similar to the male in Eury- 

 ioma (76) Cerapteroeerus Westwood. 



55. Marginal vein shorter than the stigmal 56 



Marginal vein longer than the stigmal. 



Facial impression not bounded by a distinct carina superiorly. 



(79) Ensemion Dahlbom. 



56. Facial impression and scrobes deep, bounded by a high carina superiorly. 



Scutellum Avith a tuft of bristles; stigmal and postmarginal veins very long. 



(80) Chrysoplatycerus Ashmead. 

 Scutellum without a tuft of bristles; stigmal and postmarginal veins not 



long (83) Anieetus Howard. 



Facial impression not bounded by a carina superiorly. 



(84) ZarhopaluH Ashmead, new genus. 



57. Antennas 10-jointed, with a 5-jointed funicle (85) Metallon Walker. 



Antennte 9-jointed, the fanicle 4-jointed (86) Cercobelus Walker. 



Antennas 6-jointed, the funicle 3-jointed (87) Coccobins Ratzeburg. 



AntenniB 5-jointed, the funicle 2-jointed, the club unusually long and cylin- 

 drical (77 ) Habrolepis Forster. 



Tribe IV. ARRHENOPHAGINI. 



This tribe is proposed for two genera differing decidedly from the 

 other tribes in mandibular characters, as well as in general habitus. 

 The mandibles are acutely pointed or conical, and edentate: the tarsi 

 4 or 5 jointed; while the marginal vein is wanting or puuctiform, the 

 postmarginal vein wanting, the stigmal vein sometimes present.
