246 NOTES ON AUSTRALIAN TABANIDAE, ii., 



notatus. If, according to the strict application of the rules of nomenclature, a 

 change becomes necessary, S. psarophanes Taylor (1917) might be used for the 

 species, or if, as suggested in our previous paper, S. fuUginosus Taylor (1916) 

 is merely a geographical race of the same, then that name might be given pre- 

 cedence. 



Pangonia dorsalis Macquart (1838) is apparently preoccupied by Pangonia 

 dorsalis Latreille (1821), though Macquart's species has been placed by Surcouf 

 in Corizoneura. Nothing resembling the description has been found by recent 

 collectors in Australia, and we doubt if the species is really Australian, particu- 

 larly as no 'Australian member of the Pangoninae known to us is without ocelli. 



M. Surcouf similarly expresses doubt as to Stibasoma hemiptera Surcouf 

 being Australian. A doubt is also expressed as to Acanthocera australis Ric. 

 (1915) really belonging to this genus, in view of the fact that the antennae were 

 missing when described. 



Two species Corizoneura alternans Macq. and C. sulcifrons Macq., removed 

 from the Australian list as African species, are still retained as from Oceania 

 in M. Surcouf's monogi-aph. 



The locality of Australia, given by Surcouf (p. 134) for Corizoneura um- 

 bratipennis Ric, is an evident misprint for Africa. 



Tabanus dubiosus Ric. (1915) from Australia is placed by Surcouf (p. 67) 

 as a synonym of T. dorsovittatus Macq. (1855) from South America. That 

 speeifie identity should exist between an Australian species and a South American 

 is, we consider, extremely doubtful. Possibly the resemblance may be due to 

 convergence. We do not know if T. dorsovittatus Macq. is a common and well 

 authenticated South American species; if not, the question of correct location 

 might require to be considered. 



Two other species that occur on the Australian list should, we consider, be 

 also removed as not being Australasian. Both are placed by Ricardo in Pan- 

 gonia (sens, strict.) which, as far as our knowledge goes, does not occur in 

 Australia. 



Pangonia fulviventris Macq. (1838) was described from an unknown locality, 

 but was queried by Walker as Australian. There appears to be no evidence 

 whatsoever that it is from Australia. 



Pangonia fuscanipennis Macq. (1855), described from Cape of Needles, 

 Oceania, is probably an African species. The evidence for this suggestion is that 

 several other species described in the same place and from the same locality — 

 Cadicera rubramarginata Macq., Corizoneura alternans Macq., C. sulcifrons Macq. 

 — are now known to be African species. Cape of Needles is a translation of 

 Cap des Aiguilles and in all probability is intended for Cape Agulhas, though, 

 as Dr. Marshall who made this suggestion to us also points out, there is the 

 possibility of Cape Aiguilles on Great Barrier Island, N. Zealand being the 

 place intended. As Pangonia (sens, strict.) does not occur in New Zealand it is 

 much more probable that the African locality is correct. 



Under Pangonius Latr. in Surcouf's monograph, appear several Australian 

 species relegated by Miss Ricardo to Pangonia (sens. lat.). Undoubtedly none 

 of these will come into Pangonius (sens, strict.), but further consideration of the 

 species concerned is deferred for the present. 



A further alteration made by M. Surcouf that might be noted is the revival 

 of the genus Meeomyia for species of Silvius with pubescent eyes. S. niger Ric. 

 is placed in this genus, but S. montanus Ric, S. imitator Ferg. and S. sulcifrons 

 Ferg. might also be placed here.
