It will be seen that oviposition continued for 20 days from May 9, 
a total of 2,650 eggs being deposited. Eggs deposited May 14, com- 
menced hatching June 21, an incubation period of 38 days. Two 
seed ticks from eggs de- 
posited May 14-25 were 
alive November 6, a pe- 
riod of more than 5 
months from deposition. 
The fact that this pro- 
longed survival included 
summer months shows 
remarkable vitality in the 
seed ticks of this species. 
Seed ticks of Margaropus 
annulatus seldom survive 
over 3 months in the 
summer.

Dermacentor occidentalis Marx of Niles (Morgan). 
This species was described by Koch in 1844 from ‘‘Carolina,’”’ no 
host being given. Prof. H. A. Morgan calls our attention to the fact 
that it was referred to as Dermacentor occidentalis Marx by Niles.@ 
It seems to be the common species along the Gulf coast of Louisiana, 
and Texas. (See figs. 11, 12, 13, and Pl. HI, fig. 6.) It was taken 
by Mr. J. D. Mitchell of this Bureau from cattle, horses, dogs, and 
man in Cameron Parish, La., and Calhoun, Jackson, and Victoria 
counties, Tex. In the Marx collection there is a male specimen
