46. IXODES PUTUS (Pickard-Cambridge, 1878). 



Plate V, Figs. 3 and 4; Text-figs. 254-260 (Figs. 254, 

 255, 260, original). 



Lit. etc. : Hyalomma puta Pickard-Cambridge, 1878, p. 222, PL XIII, Fig. 4 (o). 

 We are indebted to the author for sending us one of his types to examine 

 in vn. 1910. It proved to be an unfed o, bleached pale yellow by long 

 immersion in alcohol. His figures, which are very sketchy, represent the 

 dorsum, venter, and dorsal aspect of the o's capitulum. Without having 

 seen the type it would have been impossible to refer it to the species 

 described as putus by Neumann.

Ixodes fimbriatus Kramer and C. J. Neuman, 1883, p. 518. Cited by L. G. 

 Neumann, 1899, p. 127, as a good species. We are, however, convinced, 

 from the authors' description, that fimbriatus— putus <$ . (It measured 

 4 x 3-5 mm.)

Ceratixodes putus (Cambridge) in Neumann, 1902, p. 117, Fig. 4 (capitulum of <J, 

 dorsal and ventral aspects, palp in profile, somewhat inaccurate, consequently 

 not reproduced. Lahille, 1905, p. 26, reprints description of <J, $ and 

 o given by Neumann ; on pp. 138-148, more detailed description (original), 

 gives many measurements, etc., PL XIII, coloured Figs. 1-13 of ° and o

 Sutherland). 



? Ixodes eudyptidis Maskell, 1885 (see Notes on Doubtful Species, p. 291). 



Male (PI. V, Fig. 3; Text-fig. 254): very large (37 mm. I, 

 including capitulum), larger than the unfed %, narrow in front, the 

 lateral borders diverging for about one-third of the length, then parallel, 

 the posterior border only slightly convex. Scutum (33 x 2'1 mm.), 

 broadly oval, very convex, with postero-lateral borders slightly concave, 

 marginal fold moderate ; cervical grooves fairly long, shallow, divergent, 

 terminating in a large shallow depression on either side, behind which 

 two smaller circular pits are often visible; no lateral grooves; very 

 numerous unequal punctatious, and very short white hairs, generally 

 caducent, except on the posterior portion of the scutum. Emargination 

 very deep ; scapular angles very prominent, but blunt. Dorsum :
