192 On South African and Oriental Asilinae. 



Schiner described the species from Hongkong. 



Type (female) of separatus was described by the author 

 as from an unknown locality. 



Males and females from Trincomalee, Ceylon [Yerbury). 

 Male from Batu Pahat, near Johore {H. N. Ridley). Male 

 from Dindiiig, Siam. Female from Toungoo, Burmah, in 

 Forest Research Zool. Coll. Male from China (J. J. Walker). 



The species has been recorded from Singapore. 



A medium-sized robust species with blaclc legs. Scutellum 

 covered with black hairs and Avith a fringe of black bristles 

 on the border, four in number at least, not common in this 

 genus. Fore femora unarmed. Moustache black and white. 



Schiner gives the length as 12*13 mm.; these are from 

 16-18 mm. 



Philodicus lonffipes, Schiner. 



Novava Reise, Dipt. p. 179 (1868); Ost.-Sack. B. Eut. Zeit. xxvi. 

 p. 112 (1882). 



One male from Albay, S.E. Luzon {Whitehead Expe- 

 dition) ; one male from Los Bancs, male and female from 

 Cape Engano, N. Luzon [J. Whitehead) ; two females from 

 Isabella, N. Luzon : all localities in Philippine Islands. 



This species appears to be distinguished from Philodicus 

 chinensis, Schiner, by its slighter narrower build. Mous- 

 tache usually white. Schiner says the scutellum has two 

 black bristles, and gives the length as 10 mm. ; but these 

 species are larger. 



Bezzi (in ' Studies in Philippine Diptera/ i. p. 14, 1913) 

 says it is an endemic species, and suggests Erax integer^ 

 Macq., from Manila, is the same. 



Philodicus ceylonicus, Schiner. 

 Novara Reise, Dipt. p. 179 (1868). 



Males and females from Trincomalee, Colombo, Kanthalia, 

 and Kandy, in Ceylon (Yerbury). 



Distinguished from Philo'dicus chinensis by having only 

 two black bristles on the scutellum, and is usually smaller 

 in size. Schiner gives 11 mm.; these range from 11-15 mm. 



It seems very closely allied to the above species from the 

 Philippines.
