the sides of the pterothorax are much more convex.

STRONGYLOCOTES ANGULOCAPITIS Carriker 
Strongylocotes angulocapitis CARRIKER, Lice of the tinamous. p. 89, pl. 8, fig. 3, 
19386. (Host: Tinamus s. serratus.) 
This species was described from one juvenal and two adult females, 
from two different individuals of the same species of host. Two 
females from 7inamus t. tao, collected at La Cumbre de Valencia, 
Venezula, were identified as being the same. 
The two females from Venezuela have unaccountably disappeared, 
but the following additional material of S. angulocapitis was ob- 
tained at a later date: One male and two females from the type host, 
Tinamus s. serratus, collected at Rio Chaparé, Bolivia; three males 
and three females from Tinamus t. tao, taken at Sierra Perij4, Colom- 
bia; one male and one female from 7inamus tao weddelli, collected at 
Palmar, Dept. Cochabamba, Bolivia; and three males and four females 
from Zinamus major ruficeps, from Sierra Perijé, Colombia. 
The male of S. angulocapitis, hitherto unknown, is herewith de- 
scribed and figured. The shape of the last abdominal segments and 
the markings of the whole abdomen are so unique that the species 
(outside of the unusual shape of the head) may be recognized at a 
glance. 
The parasites taken on 7’. t. tao prove to be subspecifically distinct, 
as well as those from 7’. tao weddelli and the series from 7. major 
TUPICEDS. 
In the figure of the male the second segment of the antennae is shown 
as being considerably thicker than the same segment in the female. 
I have since discovered that this was caused by the position of the
