AllotJieronia, from which it differs in the regularly areolated, not 

 dentate, median segment, Theronia and Neotheronia* differ, 

 inter alia, in having pectinated claws'' (Cameron, I.e.). At first 

 I thought this genus possibly synonymous with my Orientotheronia,. 

 but it is very obviously distinct in the non-dentate 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.

j $ . A ferruginous, glabrous and nitidulous species, with the 

 antenna 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. 

 Antennae black, with the- 

 scape flavous, and the fla- 

 gellum piceous, beneath. 

 Thorax nitidulous and im- 

 punctate, the mesonotiun 

 with dense infuscate pubes- 

 cence ; lower half of the 

 propleurae, two mesonotal 

 stripes and its sides at the 

 base, petiolar area and the 

 metapleurae except above,, 

 flavous ; metanotal areae com- 

 plete, areola twice as long as 

 broad, with the external and 

 dentiparal area broader than 

 long, the former the longer, 

 with its carina apically rounded, the latter broadest externally ; 

 spiracular area? and petiolar area large, posterior areae sub- 

 triangular. Scutellum apically, its basal carinae and the whole 

 postscutellum, flavous. Abdomen nitidulous and impunctate; 

 apices of all the segments flavous ; terebra one-fifth the length 

 of the body (3 millim.). Lef/s ferruginous, with the anterior coxae, 

 and all the trochanters, flavous. Wings hyaline and highly

* This genus appears to be confined to Tropical America, so far as is at 

 present known, and to comprise numerous species, several of which were 

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

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

 1899, and "Ueber die Ichneumonidengattung Neotheronia, Kr." in Zeits. 

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