252 Genus Ixodes 



anal ring anteriorly, forming a short point at their union posteriorly. 

 Spiracles small, circular, whitish, placed somewhat posteriorly to the 

 middle of the length. Cajritulum very short (540 fi), with very short 

 sub-rectangular base, at least twice as broad as long on the dorsal 

 surface, as long as wide on the ventral surface ; auricula a small 

 tuberosity; excavate on the anterior border; porose areas medium, 

 somewhat triangular, separated by an interval equal to their breadth ; 

 in front of them a triangular median pit. Hypostome spatulate, 

 dentition 3 1 3 or 4 | 4. Palps much separated at the base, claviform ; 

 article 1 large, hollowed out on the inner side to surround the chelicerae 

 and hypostome like a cuff; the second article convex externally at the 

 base, its articulation with the third but slightly visible. Legs of 

 medium length. Coxae flattened, not winged, increasing in size from 

 I to IV, all bearing a sharp spur at the postero-external angle, internal 

 angle unarmed. Coxa I visible dorsally. Tarsi long, tapering gradually; 

 pads half as long as claws. 



The species was described by Neumann from five $s, from Ganis sp., 

 West Australia (N. C. Rothschild coll.). The specimens we possess are 

 doubtless the types, for they were derived from the Hon. N. C. 

 Rothschild's collection. Our specimens, two £s (N. 645, 646), were 

 found on Ganis familiaris, at Cranbrook, IV. 1900 (J. T. Young), and 

 on Bettongia lesueuri (marsupial rat-kangaroo), at Kogonup, XI. 1900. 

 Our figures are drawn from the latter. 



45. IXODES VESTITUS Neumann, 1908. 



Figs. 250-253 (Figs. 251-253 original). 



Lit. and Icon. : Neumann, iv. 1908, p. 7, Fig. 2 (reproduced), Fig. 3 (part 

 of venter ; omitted). 



Male : unknown. 



Female (Figs. 250, 251): Body oblong, with lateral borders parallel, 

 reddish yellow, L. 37 mm. (capitulum included), W. 22 mm. Scutum 

 cordiform 1 , with rounded sides, broadest (l - 35 mm.) toward the middle, 

 1'25 mm. long; cervical grooves absent, replaced by two elongated 

 depressions (Fig. 250) separated from the anterior border by a distance 



1 The antero-lateral borders of the Bcutum in the type are very ill-defined. They 

 appeared to us almost rectilinear (as in the accompanying figures of the nymph and 

 larva) but Neumann's figure, here reproduced, coincides with the appearance of a specimen 

 in our possession.
