 render it hopeless either to identify or describe them. 



Family A s i L i D ^. 

 Subfamily LAPHRiiNiE. 



Proagonistes * Lw. 

 Proagonistes Loew, Of v. af K. Vetensk.-Akad. Forhandl. 1857, p. 367; 'Die Dipteren-Fauna 

 Siidafrika's,' 1860, p. 170 (Abhandl. des Naturwiss. Vereins fiir Saclisen u. Thiiringen, 

 Ed. ii. p. 343). 



* This genus, founded for PrOac/onistes validus Lw., from Caifraria, was placed among the AsilinEe by its 

 author, though the latter at the same time suggested that its proper place might be among the Laphriinse, 

 it being impossible to decide the question with certainty, since the third joint of the antenna was missing in 

 the case of Loew's type. The specimens belonging to the genus in the British Museum (Natural History) are 

 for the most part in better condition, and show that Proagonistes should be assigned to the Laphriinse. The 

 following species, referred to by Loew in his original description, also belong to Proagonistes : Laphria 

 rufibarbis Fabr. (called " rwfipes " by Loew, Ofv. af K. Vetensk.-Akad. Forhandl. 1857, p, 367), W. Africa ; 

 L. ufens Walk., Sierra Leone ; and L. praeceps Walk., Natal. Besides these, the Museum collection includes 

 two Or three specimens, apparently belonging to species of this genus at present undescribed, and among 

 others an example of a very large species, with exceedingly long hind legs, from Madagascar.
