The single female of extraneus taken on Nothoprocta ornata subsp., 
Incachaca, is very close in all respects to s¢mlis, the size and propor- 
tions being almost identical, with nothing outside the range of indi- 
vidual variation. The head is, however, exactly as wide as long, 
while in s¢méls it is slightly longer than wide (0.50 by 0.49 mm.). 
This specimen I have placed under C. e. semélis.

Cuclotocephalus secundus CARRIKER, Lice of the tinamous, p. 102, pl. 11, fig. 2, 1936. 
(Host: Nothoprocta p. penilandi.) 
The differences between this species and extraneus have been fully 
explained under extraneus. ‘The species was described from a single 
female. I now have additional material of this species as follows: 
Six males and four females from Nothoprocta p. pentlandi (the type 
host) taken at Oploca and Padilla, Bolivia; three males and two 
females from Nothoprocta ornata subsp., taken at Incachaca, Bolivia. 
The four females from Oploca and Padilia seem to be identical with 
the type, while the specimens from Incachaca are slightly different, 
presenting discrepancies in size and proportion of abdomen and 
pterothorax, as well as in all three parts of the male genitalia. 
The male, hitherto unknown, may be diagnosed as follows: Very 
similar to the female except for size, dimorphism in the antennae, and 
different shape of seventh abdominal segment. The antennae are 
exactly like those of the male in eatraneus (see description under 
genus). Abdominal segment VI is as wide as in the female, but VII 
is very small and rounded posteriorly; the general shape of the abdo- 
men is very similar in the sexes, except that in the male it is much 
smaller, but of similar proportions (see table of measurements).

Types.—Male and female, adults, from Nothoprocta ornata subsp.. 
collected by the author at Incachaca, Dept. Cochabamba, Bolivia, in 
June 1980; in collection of author. 
Diagnosis—The abdomen of the male is longer and narrower than 
in secundus (0.98 by 0.63 against 0.93 by 0.67 mm.) ; the pterothorax 
in the female is wider (0.389 against 0.336 mm.) ; the basal plate in 
the male is shorter and wider (0.195 by 0.075 against 0.12 by .0084 
mm.); paramers are shorter and narrower (0.108 by 0.075 against 
0.12 by 0.084 mm.) ; endomeral plate longer but of same width (0.097
