Promachus ceylonicus, Macq. (see Ricardo, Ann. & Mag. 

 Nat. Hist. (9) v. p. 213 (1920)), I have not been able to 

 identify as a species of Philodicus. 



Asilus alOispina, Thomson, from the description, probably 

 belongs to this genus, as the author says it is near Asilus 

 agnitus, Wied., which is now said to be a synonym of 

 Philodicus javanus. Thomson's type came from Manila. 



Promachus leucotrichodes, Bigot, and Promachus tristis^ 

 Bigot, both from India, sound from the description as if 

 they might belong to this genus, rather than to Promachus^ 

 but I have not been able to identify them from the 

 descriptions. The former is described as having an ashy.
