Pygiopsylla Robinsoni (Rothschild) ♂
The female of this species has been described by the Hon. N. C. Rothschild in Novitates Zoologicae, Vol. 12, p. 483 (pl. XIII, fig. 6). The author states that it is allied to Ceratophyllus ahalae Rothsch., and indeed the head of the ♂ of this species, judging from the figure given by the British Suctoriologist in Novit. Zool. Vol. 11, pl. XI, fig. 51, resembles that of the present species as two peas. The male apparatus, however, differs, though not widely. Head. The antennal groove, which is closed behind, reaches far dorsally, so that it is very near the vertex. The grooves are united by a very fine but distinct seam. In the anterior part of the head there are three eyelike organs, two near the fore margin, one above the implantation of the maxillary palp and behind the foremost row of bristles. In the posterior part of the head there are also three eyelike organs, two near the dorsal margin, and one above the middle of the antennal club and behind the foremost row of bristles. The foremost portion of the anterior part and that of the posterior part of the head are finely punctured i. e. provided with numerous extremely fine and minute hairs. Then follows in the anterior part an oblique row of six heavy bristles, behind which one observes a second row of four ditto; then between this row and the eye, eight heavy bristles irregularly placed. The eye itself is ellipsoidal; its fore half is brown, its hind half black; its fore half projects a little into the antennal groove. The gena is provided with a rounded transparent piece.
