Subfamily EUCHARINAE. 

 The genera of this subfamily are in such confusion that it is useless 

 to attempt a synopsis before they have been thoroughly reviewed. I give 

 simply Cameron's synopsis of the four Central American genera. 



Sen ellum simple at apex. Antennae 13-jointed, simple in both sexes 



*Genus Orasama Cameron. 

 S.u'.eHum ending in two short blunt teeth which are not much longer than broad. 

 Sides of metathorax with leafdike expansions at apex. Antennae, serrate in fe- 

 male, simple in male *Genus Lophyrocera Cameron. 



Scutellum ending in processes which are as long as the abdomen. Antennae in male 

 flabellate. 



Third joint of antennae as long as all the succeeding joints together . 



*Genus Lirata Cameron. 

 Third joint of antennae not much longer than fourth Genus Kapala Cameron. 



Subfamily PERILAMPINAE. 

 Abdomen not petiolate. 



Flagellum of antenna? compacted into a short club....*Genus Philomides HaJiday. 



Flagellum long and only slightly clavate Genus Perilampus Latreille. 



Abdomen petiolate. 



Mesonotum thickly and deeply punctate *Genus Lamprostylus Foerster. 



Mea 'iiotum not so punctured *Genus Elatus Walker. 



Subfamily EURYTOMINAE. 

 Marginal vein thick, quadrate; post marginal and stigmal very short: a lunate or 

 transverse submarginal dusky shade. Male antennae similar to 9. funicle 



4-jointed Genus Decatoma Spinola. 



Marginal vein linear; no submarginal fascia; male antennae verticillate-pilose. 

 ( heeks usually acute. Mesonotum umbilicate-punctate. 



Scape much longer than first funicle joint Genus Eurytoma Illiger. 



Scape equal in length to first funicle joint Genus Bephrata Cameron. 



Cheeks usually rounded. Mesonotum with more obsolete punctures, not umbili- 

 cate-punctate. 

 Body short; metathorax almost vertical. Marginal vein not longer than stigmal. 



Genus Systole Walker.
