(8) P. palestinensis: Wing costa, five large black and five yellowish spots of unequal length; legs brown; a pale spot at junction of tibiae and metatarsi. Palpi, three pale bands, the apex white. Distinguished from P. superpictus by the unbanded legs, spotted wing fringe, and uniserrated large fore ungues in the ; resembles M. hispaniola and M. turkhudi, but these have hair like scales on the thorax, whereas P. palestinensis has rather broad flat scales; differs also from P. chaudoyei in the form of the large costal spot, in the apical half of the sixth long vein being dark, and in the presence of a deep brown median thoracic line. Palestine, Cyprus. (9) P. minimus: Wings, three nearly equal spots and an apical spot. Fringe spotted, except at sixth vein; so distinguished from P. superpictus. Legs, no trace of banding or knee spots. Mid ungues straight; fore ungues curved. Hongkong. (10) P. atratipes: Clypeus trilobed, costa uniformly black, six prominent patches of scales on the veins. Australia. (11) P. merus: Resembles P. cinereus, but distinguished by the spotted and banded femora and tibiae, also by its broader fringe spots. Has a single spot at the base of the fifth long vein. Africa.

Genus 6: Arribalzagia: (1) Ar. maculipes: Hind and midlegsmuch speckled and banded. Almost certainly transmits malaria (Liitz).
