TACHINIDAE OF ORIENTAL REGION 125 



and hesperiids are hosts of Argyrophylax and hesperiids are hosts of Thecocarcelia 

 in the Oriental area. 



Key to Oriental Genera ov CARCELIINI 



1 Four post dc setae ............ 2 



- Three post dc setae ............ 5 



2 Eyes bare. Hind coxa bare posterodorsally ....... 3 



- Eyes haired (usually very conspicuously so). Hind coxa bare or setulose postero- 



dorsally ..... CARCEL1A Robineau-Desvoidy (most forms) 



3 Four stpl setae ............ 4 



Two or three stpl setae . . . ARG YROPHYLAX Brauer & Bergenstamm 



4 Frontal setae all conspicuously reclinate. Apical scutellar setae directed upwards. 



Mid tibia with one ad seta. Antennae short, not nearly reaching to the epistome. 

 $ without an externally visible ovipositor. [Mainly Palaearctic but known from 

 Punjab] THELYCONYCHIA Brauer & Bergenstamm 



- Frontal setae normal (i.e. mostly inclinate). Apical scutellar setae horizontal. 



Mid tibia with two or more ad setae (except only one in linearifrons). Antennae 

 long, third segment usually reaching almost to the epistome (Text-fig. 53). § 

 with an externally visible flat shining sclerotized ovipositor. [Widespread in 

 Oriental Region] THECOCARCELIA Townsend 



5 Lyes bare. Parafrontals completely (,J) or nearly (9) meeting in mid-line of the 



Irons, the interfrontal area obliterated or virtually so. Propleural seta absent. 

 Ocellar setae absent. Hind tibia without pd setae. Scutellum without preapical 

 (discal) setae HYPERSARA Villeneuve 



- Eyes distinctly haired (though hairing sometimes short). Parafrontals not meeting 



or approximated, interfrontal area normal. Propleural seta present. Ocellar 

 setae present. Hind tibia with a strong isolated submedian pd seta. Scutellum 

 with the usual pair of recumbent discal setae ....... 6 



6 Mid tibia with a submedian v seta. F"ye hairing rather short and sparse (not instantly 



conspicuous). Lateral scutellar setae weaker than, or at most subequal to, the 

 basal setae. Blackish forms with narrow bright silver pollmose bands on the 

 abdomen and with the wings distinctly brownish anterobasally 



ARGYROTHELAIRA Townsend 



- Mid tibia without a submedian v seta. Eye hairing long and dense. Lateral 



scutellar setae exceptionally strong, larger than the basal setae. Paler, more 

 generally greyish or yellowish pollinose, forms with the wings not conspicuously 

 browned anterobasally . . . CARCELIA Robineau-Desvoidy (one subgenus)
