AUotJieronia, from Mhicli it differs in the regularly areolated, not 

 dentate, median segment. Theronia and Neotheronia * differ,. 

 inter alia, in having pectinated claws"' {Cameron, i.e.). At Urst 

 I thought this genus possibly synonymous with my Orientotheronia, 

 but it is very obviously distinct in the non-dent ale metathorax, 

 elevated scutellum, which is laterally margined to near its apex, 

 and the but slightly emarginate eyes. 



At present we know but a single species, from Ceylon.

cJ 5 • -A ferruginous, glabrous and nitidulous species, with the 

 antennae alone black. Head with the cheeks, palpi, mandibles,, 

 clypeus, the external orbits apically, and the sparsely but distinctly 



punctate face (which is 

 laterally elevated) flavous. 

 Antennce black, with the- 

 scape flavous, and the fla- 

 gellum piceous, beneath. 

 Thorax nitidulous and im- 

 punctate, the mesonotum 

 with dense infuscate pubes- 

 cence ; lower half of the 

 propleurae, two mesonotal! 

 stripes and its sides at the 

 base, petiolar area and the 

 metaplenrae except above,, 

 flavous; metanotal arese com- 

 plete, areola twice as long as 

 broad, with the external and 

 dentijmral arete broader than 

 long, the former the longer, 

 with its carina apically rounded, the latter broadest externally ; 

 spiracular arefe and petiolar area large, posterior areae sub- 

 triangular. Sciiiellum apically, its basal carinse and the whole 

 postscutellum, flavous. Abdomen nitidulous and impunctate;

* This genus appeal's to be confined to Tropica! America, so far as is at 

 present known, and to comprise numerous species, several of \\hicli were 

 described by Cresson (Proc. Acad. Nat. Sc. Philadelphia, 1873) and manj more- 

 by Krieger {cf. the latter's very excellent papers in Ber. Nat. Ges. Leipzig, 

 1899, and "Ueber die Ichneumonidengattung NcotJiero7iia, Xr." in Zeits. 

 Hyn).-Dip. 1905, pp. 286-333).
