 swollen base, 145// long by 72// broad. Palpi

^ This tick has been reported or sent 



[ •! to the Department of Agriculture a 



number of times from Texas and 

 Florida, where it is claimed to do 

 serious damage to chickens. So far 



as we know, it has been reported only once for cattle, 

 Packard having found it among a number of specimens of 

 Boophihis animlatus taken from cattle. We have seen one case from 

 Florida in which a chicken was literally covered with the hexapod stage.

 imens upon which this description is based they are contiguous. 



^Hassall has figured this from live specimens as a disk with ventral concavity; in 

 preserved specimens it is distinctly convex ventrally.
