Subgenera o/Asilus. 



Williston in his 1908 edition of ' Manual of N. American 

 Diptera ' considered many of the subdivisions of the old 

 genus Asilus very vague and often not based on true generic 

 characters, and placed them in his table of genera as sub- 

 genera. Prof. Hine in " Robberflies of the Genus Asilus,'^ 

 Ann. Ent. Soc. America, ii. no. 2, pp. 136-172, follows 

 Williston. 



Glaphyropyga, Schiner. 

 Verh. zool.-bot. Ges. Wien, xvi. p. 674 (1866). 



There are only two species recorded in this genus — 

 G. himantocerus, Wied., from Brazil, for which Schiner 

 formed the genus, and G. australasia, Schiner, 'Novara' 

 Reise, Dipt. p. 187 (1886), from Australia.
