64 R. W. CROSSKEY 



karnyi with hervei. (2) Ormia bicornis Malloch. Contrary to Townsend's (1938 : 

 269) statement this species does not require a new genus but correctly belongs in 

 the genus Phasioormia Townsend to which it is here assigned.

1 Wing with cell R 5 open or closed just by the wing margin, rarely with a short petiole 



that is shorter than r-m. One post ia seta (well developed) ..... 2 



- Wing with cell R b closed far before the wing margin, and with a very long petiole 



that is about twice as long as r-m (Text-fig. 91). No post ia seta (but sometimes 

 a small adventitious seta present in an intra-alar position close behind the transverse 

 suture) AULACEPHALA Macquart 



2 Antennae very small, their length much less than a quarter of the eye-height (the 



apices separated from the margin of the oral cavity by a distance much greater than 

 their own length, Text-fig. 63). Epistomal region forming a dorsoventrally 

 elongate and flattened strip constricted between widened subfacials (Text-fig. 63). 

 Oral cavity very reduced. Vibrissae not clearly differentiated . THEROBIA Brauer 



- Antennae not exceptionally small, their length more than a quarter of the eye-height 



(the apices separated from the margin of the oral cavity by less than their own 

 length. Text-fig. 64). Epistomal region not so modified, wide and not obviously 

 constricted between broad subfacials (Text-fig. 64). Oral cavity not noticeably 

 reduced. Vibrissae differentiated ........ 3

Tribe GLAUROCARINI 



As understood at present this small tribe contains only the two genera Glaurocara 

 and Doddiana, both of which are represented in the Oriental Region. Keys to the 

 Oriental species have been provided by Crosskey (1962), and a preliminary tribal 

 diagnosis by Crosskey (1973&). The group is poorly studied, largely on account of 

 the paucity of material in museum collections (which may be due to the fact that 

 the adult flies appear to be most active nocturnally). The early stages of Doddiana 

 are undescribed but the first instar larva of Glaurocara is a perfect planidium (Cross- 

 key, 1965) exactly like that of Ormiini (to which the tribe appears to be closely 

 related). The only host reported from the Oriental Region is the sugar-cane borer 

 Chilo sacchariphagus (Bojer) which is attacked by Doddiana mellea in Java; an 

 unsuccessful attempt has been made to introduce this tachinid into Mauritius for 

 the control of the same moth pest (Ghani, 1962). In Africa Glaurocara flav a Thom- 

 son has tettigoniid hosts (Crosskey, 1965), and it is likely that the Oriental species 

 of Glaurocara also parasitize Orthoptera. 



Mention may usefully be made here of the publication date of Thomson's work 

 in which the description of Glaurocara appeared. This has usually been cited as 

 1868 in accordance with the date on the title-page, but it is known that the actual 

 date of issue was in 1869. The latter year-date is therefore here cited.
