CLASSIFICATION AND HABITS OF TICKS. 61 
given. The writers’ opinion of the specific identity of specimens from 
Venezuela, on cattle, with Texas specimens, on horse and peccary, is 
confirmed by Mr. Banks. The species may be distinguished from 
maculatum readily by the characters given in the table. (See also 
figs. 9 and 10 and PI. IV, figs. 3, 4.) 
The species has been reported from, and seems to be generally dis- 
tributed through Mexico and Central America. It has been reported 
from Colombia, Venezuela, Brazil, and Argentine Republic in South 
America. Neumann also reports it from Cuba and Jamaica. In Texas 
Mr. J. D. Mitchell has taken it in Live Oak County from the peccary 
and horse. Mr. Banks reports specimens from Louisiana, Missouri, 
and Florida. In addition to the hosts mentioned it has been reported 
from toad (Bufo agua), capy- 
bara (Tydrochxrus capybara), 
an ant-eater, and man. 
Stoll, in the Biologia Cen- 
trali- Americana, states that 
this species is the most com- 
mon of all [xodidz in Central 
America, and gives some in- 
formation concerning its hab- 
its. He has never found the 
male in a parasitic state, but 
has found it free on grass and 
bushes in Guatemala. The fe- 
male, which he states abounds 
in the woods and fields on 
grass and bushes, is occasion- 
allv brushed off by horses, ecat- Fic. 10.—Amblyomma cajennense: Coxe of male and

tle, or dogs, and even man. 
It adheres tenaciously to the skin, remaining when undisturbed for 
several days until filled with blood. If forcibly removed, the beak 
breaks off and remains in the wound, causing a disagreeable and 
sometimes painful inflammation. The young, which are distinguished 
by the inhabitants of Guatemala by the name of ‘‘ mostacilla,”” hang to 
the grass in clusters of thousands, especially during the dry seasons. 
By their creeping on the skin and frequent biting they form one of the 
greatest plagues of travelers. 
Ina letter accompanying specimens of this species from Venezuela the 
writers are informed that the ticks do great damage by producing fever 
in cattle, which become weak and in many cases die. It hardly seems 
possible that the malady can be Texas fever; nevertheless this species 
may possibly transmit some disease.
