was noted), as has also been confirmed for New Guinea likewise. Secondly, two 

 high altitude specimens have been seen in BMNH collection from Kenya and Uganda 

 that have the basal wing veins more orange coloured than usual, the general colouring 

 deeper bluish black, and the downcurved parafacial bristling stronger: the male 

 genitalia show that these specimens can be assigned to ruralis, but the cereal prong 

 is smaller than usual. This and the other differences from typical ruralis are 

 considered to be infraspecific, for minor differences are to be anticipated in high 

 altitude populations. 



Key to Oriental Genera of VORIINI 



Parafacial with a very strong proclinate seta inserted at its upper end near the 

 lowermost frontal seta, sometimes accompanied by some weaker proclinate setae 

 (Text-fig. 56). Arista thickened for about half its length or only slightly more than 

 this, the second segment not elongate .... VORIA Robineau-Desvoidy 



Parafacial bare, without either hairs or setae below the lowermost frontal seta. 

 Arista thickened on more than half its length (not conspicuously so in Hyleorus 

 takanoi), the second segment elongate (at least twice as long as broad and usually 

 more than this) ............ 2 



Eyes haired. Prosternum haired. Facial ridges setulose on half their height (in 

 profile no gap between the uppermost setula on the facial ridge and the lowest 

 frontal seta). Wing with M 2 appendix very long, subequal in length to or longer 

 than the section of M between m-cu and the bend (Text-fig. 92). Propleuron bare 

 or haired . . HYLEORUS Aldrich 



Eyes bare or virtually so. Prosternum bare. Facial ridges bare (except for the 

 usual small setulae near vibrissae). Wing with M 2 appendix or fold short, much 

 shorter than the section of M between m-cu and the bend. Propleuron bare

Tribe WAGNERIINI 



This small suprageneric taxon was originally proposed by Mesnil (19391? : 42), 

 as Wagneriina, and was treated as a tribe by van Emden (i960). For convenience 

 I here follow van Emden's practice, treating the group as a tribe exactly equivalent 

 to Mesnil's Wagneriina (see Mesnil, 1966 : 891), but the wagneriines are unques- 

 tionably very close phyletically to the voriines and perhaps should not be accorded 

 separate rank at either tribal or subtribal level. The group includes parasites of 

 noctuoid Lepidoptera and is found mainly in the Holarctic Regions and in the 

 Ethiopian Region; it has not been recognized in the Australian fauna. In the 

 Oriental Region the tribe occurs mainly in the border areas with the Palaearctic 

 (though one species has been described from the Philippines), and is represented 

 by two genera, Peteina Meigen and Periscepsia Gistl. 



Peteina is not strictly speaking a member of the Oriental fauna and is included 

 here solely because of the occurrence of P. hyperdiscalis Aldrich in the Szechwan 

 Province of China and in Tibet and Nepal. Actually this nominal species, despite 

 the supposed differences mentioned in the description by Aldrich, is almost certainly 

 not distinct from the widespread Eurasian type-species of Peteina, viz. P. erinaceus
