i Femora reddish yellow, or almost entirely so. Scutum with long pale yellow hair 

 resembling that of pleural regions. Pollinosity of abdomen forming definite pale 

 basal bands well visible to naked eye on T3, T4 and T5; ground colour of last 

 two visible tergites extensively black. Hairing of parafacials nearly all pale

- Femora brownish black. Scutum mainly with short blackish hair. Pollinosity of 

 abdomen rather evenly distributed and shifting with direction of light, tergites 

 not showing definite pale basal bands to naked eye; ground colour of last two 

 visible tergites mainly reddish. Hairing of parafacials nearly all black, only pale 

 yellow at lower ends of parafacials against the eyes. . . chinensis Wiedemann 



Tribe ERYCIINI 



The Goniinae with large pre-alar seta are extremely difficult to classify satis- 

 factorily, and the immense number of genera to be studied makes it unlikely that 

 a much improved arrangement will emerge in the near future. Specialists seem 

 agreed, however, that the various tribes currently recognized are largely artificial 

 assemblies of genera bearing but little relationship to the probable phyletic affinities. 

 Nevertheless it is impossible when dealing with a little known fauna to break free 

 from an existing classification, imperfect though it may be, unless some properly 

 formulated new classification has been proposed to supersede it. Such is not the 

 case with Goniinae, although several workers consider that its constituent genera 

 should be reshuffled into fewer tribes redefined on the basis of the reproductive 

 habit (rather than the conventional external adult morphology). Hence it is 

 necessary here to continue to recognize the so-called tribe Eryciini for all those 

 Goniinae with large pre-alar seta that cannot obviously be associated with any of 

 the other tribes: but it must be appreciated that the tribe in the sense used here is 

 a somewhat disharmonious aggregation of genera of polyphyletic origin - a con- 

 venience group to be recognized temporarily for the purely practical purpose of 

 identification within the Goniinae. 



As here used the Eryciini equates with the tribal entity recognized under this 

 name by van Emden (1954), and (certain genera excepted) corresponds to Mesnil's 

 Erythrocerina, Trypherina and Masicerina taken together (in Lindner's Die Fliegen 

 der Palaearktischen Region 64g) ; there appear to be no forms in the Oriental Region 

 fitting Mesnil's (op. cit.) group Baumhaueriina, although such forms occur in southern 

 Australia. A few genera that Mesnil placed among the sturmiines - including 

 Dolicho colon, Aneogmena and Psendoperichaeta - seem to have rather little relation 

 to Sturmia and are here treated as eryciines because of their close resemblance to 

 certain Eryciini (e.g. Dolichocolon to Frontina, Aneogmena to Rhinomyodes and 

 Simoma, and Pseudoperichaeta to Aplomya and Phryxe).
