34 R. W. CROSSKEY 



- Scutellum with four pairs of marginal setae (a very strong supernumerary pair of 



marginals present between the normal apical and subapical pairs). Bend of vein 

 M forming a sharp right-angle and with a well developed M 2 appendix. Parafacials 

 haired (hairing dense on whole parafacial in <J, sparse and mainly on middle and 

 lower parts in the $). [Terminal claspers of $ abdomen as Text-fig. 113] 



CALYPTROMYIA Villeneuve 

 2 Abdomen pale yellow on the basal half and blackish brown apically. Palpi yellow. 

 Mid tibia with two ad setae. Upper occiput bare behind the postocular row. 

 [Terminal claspers of $ abdomen as Text-fig. in] . PSEUDOBRULLAEA Mesnil 



[Only the 9 holotype is known. According to Mesnil's description the mid tibia 

 has only one ad seta, but examination of the holotype shows that whilst only one 

 ad remains on each mid leg there is a second well developed pore on each mid 

 tibia basad of the existing ad seta; two ad setae on the mid tibia is evidently the 

 natural state.] 



- Abdomen with uniformly black-brown ground colour. Palpi dark brown. Mid tibia 



with a long series of about four or five ad setae. Upper occiput with irregular long 



fine brown to blackish hairs ....... Undetermined genus 



[Running here is an unidentified o* specimen from China in BMNH that cannot 

 be generically placed until Old World Leucostomatini are adequately revised and 

 generic limits more certain. Its facies is that of Leucostoma and Calyptromyia, 

 especially the head form, but it differs from the former by having cell R h open 

 and from the latter by the key characters in couplet 1 above.] 



Tribe EUTHERINI 



The tribe Eutherini and its single constituent genus, Euthera Loew, have been 

 characterized by Crosskey (19736 : 40). Some authors consider that the anomalous 

 European genus Redtenbacheria Schiner should be placed in the tribe, but I am 

 not fully convinced that close phyletic affinity exists between Euthera and Redten- 

 bacheria and prefer to consider the Eutherini as monogeneric for Euthera (of which 

 the names Eutheropsis Townsend, Macreuthera Bezzi and Preuthera Townsend are 

 synonyms) . 



Euthera is very little known from the Oriental Region. The first mention of 

 the genus from the region appears to be that of Bezzi (1925a), who reported that 

 Villeneuve had seen a specimen of E. mannii Mik from Formosa. Townsend 

 (1938 : 210), who did not see this specimen, considered that it must represent an 

 undescribed species of Eutheropsis, and at the same time mentioned a male specimen 

 from Ceylon in the DEI, Eberswalde, collection that he also considered to belong 

 to an undescribed species. One species is known from Pakistan. 



I have not seen the specimens from Formosa and Ceylon, but mannii is a dis- 

 tinctive species that was known to Villeneuve and it may be presumed that it was 

 rightly identified from Formosa. This is likely, as it is now evident that the 

 distribution of mannii is not confined to southern Europe and Asia Minor, but 

 extends into the Oriental and Ethiopian Regions. Narayanan & Ghai (1961) 

 have recorded mannii from India, and Bezzi (1925a) noted that Villeneuve had 

 seen the species from 'British East Africa'. The location of the East African 

 specimen(s) seen by Villeneuve is not known to me, but (as with the Formosan 

 specimen) it is likely that Villeneuve's determination was correct, particularly
