antennae in the mounted specimen. Apparently this second segment 
(and to some extent the third) is not cylindrical, but flattened, its 
width differing according to the side shown. The figure of the male 
shows clearly the chaetotaxy of the abdomen, and so a detailed descrip- 
tion of same seems superfluous. We have the following subspecies of 
angulocapitis : 
STRONGYLOCOTES ANGULOCAPITIS ANGULOCAPITIS Carriker 
FIGURE 6, a—d 
Of all the races this 1s the smallest in all dimensions; the paramers 
are equal to those of S. a. taoi (described below) but shorter than 
the other two races (also described below); the endomeral plate is 
longer than all the other races except ruficeps,; pterothorax scarcely 
wider than abdomen in the male; the only race in which the female 
has the pterothorax wder than in the male; hairs on abdomen long 
and coarse ; terminal segment in the male small (see fig.) ; pterothorax 
with posterior angle rounded and shorter. 
STRONGYLOCOTES ANGULOCAPITIS TAOI, new subspecies 
FIGURE 5, é, f 
Types.—Male and female, adults, from Tmmamus t. tao, collected at 
Tierra Nueva, Sierra Perija, Colombia, by the author on July 8, 1941; 
in U.S. National Museum. 
Diagnosis.—The width of head at the trabeculae is equal to that of 
angulocapitis but is wider at the temples and longer; in the female 
the head is wider at the trabeculae and narrower at the temples than in 
angulocapitis and in the male of taoz,; the pterothorax is much wider 
than the abdomen in the male; the pterothorax of the female is nar- 
rower than that of the male; the abdominal hairs are fewer and 
shorter; the terminal segment in the male is large; the posterior angle 
of the pterothorax is sharp and longer posteriorly. 
STRONGYLOCOTES ANGULOCAPITIS WEDDELLI, new subspecies 
Ficure 6, e, f 
Types.—Male and female, adults, from Tinamus tao weddelli, col- 
lected by the author at Palmar, Dept. Cochabamba, Bolivia, July 12, 
1927 ; in collection of the author. 
Diagnosis.—The head is the same width at the trabeculae in both 
sexes but much narrower at the temples in the female; pterothorax 
wider than in angulocapitis and ruficeps but narrower than in ¢aoz; 
the pterothorax of the female is narrower than that of the male; hairs
