214 Genus Ixodes 



ix. 1905 (D. Robertson); (N. 501, ?), from horse, Cambridge, 

 V. 1908 (G. A. Banham); (N. 1068, j"s, ?s) from nest of Cotile 

 riparia, Lyndhurst, Hants, vil. 1900 (N. C. Rothschild); (N. 605) 

 from Cotile riparia, Warsbrough Bridge, Barnsley, VII. 1906 (A. 

 Whittaker; ex N. C. Rothschild coll.); (N. 1051, ?), from grass, on 

 the Downs, Lizard, ix. 1909 (L. Cobbett); (N. 19, ?), from dog, 

 Lougner Hall, Shrewsbury, IV. 1906 (R. F. L. Burton.) The last- 

 named gentleman has, moreover, sent us from the same locality (N. 499, 

 larva) from mole, xi. 1908; (N. 1137, ?s, o), from ferrets, vi. 1910, 

 and (N. 1141, 1143, many ,/s, !j!s, Os) from nests of three sand-martins 

 (C. riparia) on the banks of the River Severn, Shrewsbury, VII. 1910. 

 Ireland: (N. 62, ?s) from dog, Sligo, ix. 1905 (M. F. Nuttall). 

 Germany: (N. 768, $ s), from dog, Kittendorf, Mecklenburg-Schwerin, 

 vin. 1908 (G. H. F. Nuttall). Prance: [Neumann, 1901, records (?) 

 "inchoatus" from the fox (R. Blanchard coll., Paris); from the 

 dog, Toulouse (Neumann coll.); and badger (Railliet coll., Alfort)]. 

 N. America: [Banks, 1908, p. 32, records the species (2$s) as occur- 

 ring either on the red squirrel or fox, but does not state the locality].

29. IXODES TEXANUS Banks, 1909. 



Figs. 210, 211 (original). 



Banks, vi. 1909, p. 172, Figs. 16, 17 ( ? capitulum, coxa I, tarsus 4 

 and spiracle. Inaccurate). 



Male : unknown. 



Female : Scutum as long as broad 1 , hexagonal, with posterior border 

 broadly rounded, broadest about the middle. Cervical grooves broad, 

 shallow, nearly parallel, far apart, reaching the posterior border, the parts 

 external to them, and especially the scapulae, being rugose, the area 

 between them pitted with deep punctations, more or less confluent. 

 No lateral grooves. Scapulae moderately prominent. Dorsum with 

 very short white hairs; punctations inconspicuous. Capitulum: base 

 sub-trapezoid, narrower in front, very rugged, its sculpture rendering 

 the porose areas ill-defined. Porose areas irregular, separated by about 

 their breadth, the interval rugged ; no distinct auriculae. Palps rather 

 short and broad, with straight external and very convex internal contours, 

 the internal contour very rugose, giving a beaded effect ; article 1 



1 The scuta of our three specimens measure respectively l'lxl-2, 1-2x1*1, and 

 lxl mm. Our most replete specimen measures 4-9 x 3'3 mm. Banks gives the body-length 

 at 6-5 mm., but docs not state if this is the maximum length which may be attained in 

 gorged females.
