but as Bigot was notoriously unreliable about provenances of his material it is 

 possible that Bellina did not have an Oriental type-locality. Because of this, I 

 have checked Robineau-Desvoidy's description against all Phasiinae known to me 

 or in the BMNH collection but have been unable to come to any conclusion on 

 the probable identity of Bellina. This is unfortunate, as it leaves the name in 

 limbo as a nomen dubium when it would be preferable to bring such a short con- 

 venient name into use for a recognizable concept. Some features of the description 

 seem to indicate that Bellina might be the same as Townsend's Catapariprosopa, 

 but the latter genus is unusual among cylindromyiines in having the basal segments 

 of the arista elongate whereas Robineau-Desvoidy states that these segments are 

 very short in Bellina ('premiers articles du Chete tres-courts'). On the whole the 

 fit of Robineau-Desvoidy's description of Bellina to the characters of Catapariprosopa 

 is not sufficiently close to warrant the sinking of the latter into synonymy with 

 the former; for the time being, until a species is discovered that will fit convincingly, 

 Bellina must remain enigmatic but may as well repose in Cylindromyiini as anywhere 

 else. 



Finally it should be recorded that I believe the female holotype of Townsend's 

 Epseudocyptera epalpata to be a teratological specimen with an aberration in the 

 palpi. This is the type-species of Epseudocyptera, a genus that Townsend (on the 

 basis of the holotype of epalpata) considered to be non-palpate. In fact the holotype 

 lacks the right palp completely but on the left side shows a small papilliform palp. 

 The certainty is that palpi are normally present in the species to which the epalpata 

 type belongs, and I therefore treat Epseudocyptera as synonymous with Lophosia 

 despite virtual absence of palpi in the type of its type-species (see couplet 22 of the 

 key to Oriental Lophosia species on p. 33). 



Key to Oriental Genera of CYLINDROMYIINI 



[Note. The genus Bellina cannot be included as it has not been recognized since its description 

 and no material exists.] 



1 Palpi absent. Cell R b with well developed petiole (Text-fig. 88). Propleuron 



bare or haired. Hind tibia with or without submedian pv setae. Intermediate 

 abdominal tergites without discal setae ........ 2 



- Palpi present. Cell i? 5 with or without petiole. Propleuron bare. Hind tibia 



without submedian pv setae. Intermediate abdominal tergites often with discal 

 setae ..... ......... 3 



2 Abdomen strongly clavate (Text-fig. 122). Basal node of R i + 5 on the ventral surface 



with a series of exceptionally long strong hairs (the largest of them much longer 

 than r-m). [Forms with 'waisted' body shape that are obviously Hymenoptera- 

 mimics] GEROCYPTERA Townsend 



- Abdomen subcylindrical or subfusiform (Text-fig. 119). Basal node of R i + 5 with 



tiny inconspicuous hairs ventrally that at their strongest are not longer than r-m. 

 [Forms without 'waisted' body shape that are not obviously Hymenoptera-mimics] 



CYLINDROMYIA Meigen 



3 Arista thickened on more than half its length and with both basal segments (especially 



the second) much elongated. Abdomen seen directly from above appearing tri- 

 segmented (Text-fig. 121), with a heavy elongate postabdomen recurved under the 

 preabdomen CATAPARIPROSOPA Townsend
