spur of the male. Hypostome larger than that of male and with Seven or eight denticles in inner files and ten or eleven denticles in outer files; otherwise similar to that of male.

Scutum: Length-width ratio approximately equal, lateral

margins gradually tapering from scapulae to eyes and from eyes to bluntly rounded posterior margin. Eyes oval, slightly arched, more distinct and larger than in male, situated on lateral margin at widest point of scutum. Cervical oves curved around eyes and extending to posterolateral margin distally; delineating a broad median, slightly shagreened field bearing widely scattered, short hairs.

Spiracular # subcircular, with three rows of large goblets encircling aperture. Genital aperture shield shaped, in same position as in male. Genital grooves similar to those of male to level of anus, where they continue as slightly convex grooves extending almost to the posterior margin of the body. Hairs in lines similar to those of male except that these lines extend almost to posterior margin of body; hairs laterally only slightly longer and denser than ventrally.

Legs robust but not markedly modified. Coxae similar to those # males except that they are wider in relation to length and the spurs and ridges are even more reduced. Free # with marked constriction between first and second segment similar to that of males. Tarsi longer and narrower in comparison to those of males but otherwise similar; claws and pads similar to those of males.

NYMPH and LARWA: Undescribed.
