and characteristic forms ; no subdivision into smaller genera has yet been proposed, but 

 in the following pages I have made an attempt to do this for the Indian species. The 

 Dacinae are represented by very special forms, different from the African ones and 

 I propose to separate them under the generic name of Badvocera. Peculiar genera of 

 the region are also Meracanthomyia , Rioxa, Ptilona, Vidalia, Themara, Acanthoneura , 

 Henicoptera, Rhahdochaeta and Myiopardalis. 



The peculiar character of the Oriental (and also of the Indian) fauna seems to be 

 the great variety and richness of Ceratitininae and the very numerous forms with a 

 plumose arista. This last character is also shown by many Ethiopian and Australian 

 forms, while in Europe we have, on the contrary, only Euphranta with a short 

 plumose arista. In North and South America there are no such forms, the arista 

 being only pubescent or very shortly pilose. 



Comparison between Oriental and Australian or Ethiopian faunas, like that 

 which Loew has established between European and American faunas, is not at 

 present possible. 



5. CRITICAL REVIEW OF THE ORIENTAL AND AUSTRALIAN 

 TRYPANEIDS HITHERTO DESCRIBED. 



There are two catalogues of the Oriental Trypaneids, one by Bigot, the other by 

 Van der Wulp. The first, pubHshed in the Journal of the Asiatic Society of Bengal, 

 ii, 1892, p. 220 — 227, is very incomplete and confused; Bigot had no idea of the 

 natural limits of the family or of the genera, as is shown by the MS. names in the 

 Indian Museum collection. 



Van der Wulp's Catalogue (the Hague, 1896, pp. 186 — 195) is very diligent and 

 complete, but not critical, as he refers to the species of Walker and Doleschall as 

 these were described, without any attempt to place them in correct genera. These 

 species are the misfortune of the Oriental fauna, and it seems that the types are in 

 some cases lost ; but fortunately Walker has described only a few species from 

 India. Van der Wulp also was little acquainted with Trypaneids, as he described 

 an Oxyna as a Leptomyza , an Acidia as an Euxesta, and even the common North 

 American Ortalid Chaetopsis aenea as an Aciura ! 



In the following review I have included the few known Australian species, 

 because they have relation with the Oriental forms and no catalogue of them exists . 

 The species marked with an asterisk (*) are Indian (including Ceylon), and those with 

 two (**) are Australian. 



1. absolutus (Dacus), Walker, 1861 (Proc. Linu. Soc, vi, 22, 13), from Cerain. Seems to be a 



Badrocera allied to ferruginea. Type in I,ondon, British Museum. 



2. **acrolenca {Tephritis),SchmeT, i868 (Diptera Novara Reise, 268, 112), from Sydney. Seems to 



be a Tephritis, with obtuse anal cell ; but if the observation on p. 269 is exact, this 

 species may belong to the new genus Tephrella. Type in Vienna, Imperial Museum. 



3. acroleucus (Z)«cms), Wiedemann, 1830 (Auss. Zweifl., ii, 520, il), habitat unknown. Is not 



a Dacine ; the plumose arista clearly indicates one of the Ceratitininae from the Oriental 

 region; but it is doubtful if this form is a Trypaneid or not. Type in Vienna, Imperial
