feature which sepai-ates the species from all other Owl Philopteri 

 so far examined. Basal plate : Rather short, broad ; latera,l 

 margins strongly chitinised along posterior half. The hind 

 margin juts out medially into a prominence beneath the endo- 

 meral plate. Parameres : Elongate rounded rods, graduated to 

 a slender distal end, and slightly curving inwards towards one 

 another. Endomeral plate : Quadrilateral, as broad as the basal 

 plate to which it is attached, and about half the length of the 

 parameres. The endomeral plate has a marginal band which

along the lower side deepens considerably in the middle part, 

 where it bends upwards between the parameres and sends back- 

 wards across the plate two diverging splints. Each of these runs 

 halfway along the oblique base-line of the articular surface of the 

 paramere. The forked rod (see text-fig. 1) is homologous with 

 similar parts in P. cursor, P. ceblebrachys, and P, athene (see 

 text-figs. 1-3).
