ment of humeral setae in a regular triangle. Unusual features found within the 

 group, and not occurring elsewhere in Oriental eryciines, include the presence of 

 long fine setulae on the posterodorsal edge of the hind coxa (found in Rhinaplomyia) 

 and the (usually) long spatulate palpi found in Phebellia and Rhinaplomyia. The 

 group is so far known from very few Oriental specimens, but to judge from these 

 is confined to the northern borders of the Oriental Region; it should perhaps be 

 looked upon as an essentially Palaearctic group that spreads southwards for a 

 short distance into the Oriental area. The group is apparently unrepresented in 

 Australia, where no eryciines with the humeral setae in a triangle are known to 

 occur (except possibly for Walker's 'Tachina' calliphon which has the setae in a 

 triangle but is of uncertain Australian provenance: see Crosskey, 19736 : 97). 



Key to Oriental Genera 



Hind coxa with long fine setulae on the posterodorsal surface (as in Carcelia s.str.). 

 Intermediate abdominal tergites with numerous erect and irregular discal setae, 

 many of which are conspicuously spiniform. Epistome slightly to enormously 

 prominent, visible in front of the vibrissal base in profile RHINAPLOMYIA Mesnil 



Hind coxa bare on the posterodorsal surface. Intermediate abdominal tergites 

 either without differentiated discal setae or each with one regular pair that are 

 not at all spiniform. Epistome not prominent, invisible in profile ... 2 



Abdominal T3 with four median marginal setae. Three stpl setae. Facial ridges 



bare except for the usual few setulae adjacent to the vibrissae .... 3 



Abdominal T3 with two median marginal setae. Two stpl setae. Facial ridges 



finely setulose on their lower two-fifths . 'Exorista' seniorwhitei Baranov (? genus) 



Facial ridges prominently visible in profile. Mid tibia with one ad seta. Abdomen 



without discal setae. Palpi yellow ' Aplomyia' carceliaeformis Yilleneuve (? genus) 



Facial ridges not visible in profile. Mid tibia with several ad setae. Abdominal 



T3-T5 each with discal setae. Palpi blackish . PHEBELLIA Robineau-Desvoidy 



ERY THR OCERA -group 



Head shape normal. Eyes bare or sometimes with very short sparse inconspicuous hairs. 

 Facial ridges bare or setulose, sometimes visible in profile. Parafacials bare. Frontal setae 

 not reclinate (except in Elodia). One or two pairs of reclinate orbital setae. Upper occiput 

 flat or slightly swollen (except a little sunken in Elodia), with black setulae behind the postocular 

 row. ^ with or without proclinate orbital setae. Arista normal, at most thickened on three- 

 fifths of its length, basal segments short. Humeral callus with three setae in a straight line, 

 sometimes an additional fourth seta set forwards (only two setae clearly differentiated in 

 Elodia). 3 + 4 dc setae [3 + 3 in some African species]. Normally three or four stpl setae, 

 rarely only two. Wing cell 7? 5 open or closed exactly at wing margin. Bend of vein M forming 

 a gentle evenly rounded curve, usually far from m-cu and near to wing margin (e.g. as Text- 

 fig. 105). Second costal sector bare or haired ventrally. Mid tibia with one ad seta. Hind 

 tibia with or without pd preapical seta.
