types in that Institution, I am enabled to place in their correct 

 genera a number of Walker's species, these species being noted 

 under each genus in question. 



In the case of two species {aperta, Wlk., and manifesta, Wlk.) 

 which have been compared by Mr. F. M. Howlett with the British 

 Museum types, I have, as the specimens appear to agree well 

 with the descriptions, accepted the identifications. t,^ 



After obtaining a more or less reliable generic classification, 

 the much more difficult problem of separating the species had 

 to be encountered, and it is to be regretted that, so far as this 

 paper is concerned, the carrying out of this task has been chiefly 

 comparative, analytical tables of the species being obviously 

 impossible without a more precise acquaintance with a larger 

 proportion of the species; Walker's species being known to me 

 almost wholly from descriptions only. Therefore, as hereinafter 

 stated, my provisional ' ' grouping ' ' of species in the genera 

 Hyper alonia, Exoprosopa and Anthrax must be received with a 

 certain amount of caution, and it must be understood that they 

 are not intended to represent natural affinities, being based almost 

 entirely on wing-markings. The reason of this is, that this character 

 is, in cabinet specimens (which are generally more or less damaged, 

 when of questionable antiquity), the most lasting one, being the 

 least affected by time, dust, mould, etc. Also it is the only 

 character mentioned by every author. Concerning the geographical 

 limits of this catalogue, the only dubious point is the inclusion of a 

 few species described from China. If these latter are from South 

 China, they may be regarded as belonging to the Oriental Fauna, 

 but if proved to occur in North China only, they must be elimin- 

 ated from this list and relegated to the Palsearctic Catalogue. 



N.B. — The descriptions and redescriptions are placed all 

 together at the conclusion of the catalogue, and after these I have 

 given a supplementary list of those species which are known on 

 the confines of the Oriental Region (Turkestan, Persia, Arabia, 

 and Queensland). Any of these species might easily be met with in 

 the Oriental Region, whilst any of the Palsearctic species may occur 

 in the Himalayas ; a list of these latter can be found in the recent 

 Palsearctic Catalogue. I also add a list, probably not so complete 

 as it might be, of Bombylidse, which have been described from 

 unknown localities, as some of these may prove to be Oriental.
