0. turicata 59 



Males average 3 - 5x 25mm.; females 6 x 4mm.; nymphs 22 xl - 5 mm. 



Neumann's description, from which the above is partly taken, is 

 based on numerous specimens collected in Guanajuato, Mexico, by 

 A. Duges 1 . 



Fig. 87. 0. turicata. Digit, 90 m I. (Nn. 1896, fig. 33, modified). 



This species attacks pigs, cattle and man. Its bite is painful and is 

 said to produce grave effects. The 0. americanus of Marx was found in 

 Texas on the nostrils of the horse, in South America on the llama 

 and in Florida on the tortoise, Xerobates polyphemus, whose burrows it 

 appears to infest (see Hubbard, 1894, p. 306). Banks, 1908, p. 18, has 

 moreover seen specimens from Florida (in gopher holes), New Mexico, 

 Arizona and California (on cattle).

Synonymy : Argas talaje GueVin-Meneville, 1849, pp. 342, 343. 



Ornithodoros rudis Karsch, 1880, p. 141 ; identified by Neumann, 1901, p. 259, 

 as O. talaje after examination of type. 



(lArgas coniceps Canestrini, 1890, p. 535. Regarded as A. reflexus <J by Canestrini 

 and Fanzago, 1897, p. 193. From Canestrini's description and figure (see Icon.) 

 Neumann, 1896, p. 36, appears almost justified in referring it to 0. talaje, of 

 which he makes it a variety : 0. talaje coniceps (Canestrini). The determination 

 is, however, doubtful.)

 which our figure was drawn.
