but in ¢aoz it is much narrower than long (0.755 against 0.67), while 
in ruficeps it is smaller in all dimensions. 
The genitalia differ from those of taoz more in this race than in 
chocoensis, being narrower at base of paramers and having the para- 
mers considerably shorter; the endomeral plate is shorter and slightly 
narrower, while there is the same constriction of the basal plate as in 
taor.

AUSTROKELLOGGIA INTERMEDIA Carriker 
Austrokelloggia intermedia CARRIKER, Lice of the tinamous, p. 176, pl. 31, figs. 
1-1b, 1986. (Host: Nothocercus n. nigrocapillus, Bolivia.) 
A series of 9 males and 13 females of this interesting species was 
taken on two individuals of Nothocercus bonaparti, collected by the 
author at Tierra Nueva, Sierra Perija, Colombia, in July 1941. An 
exhaustive series of measurements of both sexes shows considerable 
variation, especially in the head measurements, which run as follows:

Compared with the measurements of two males and four females 
of the type series of intermedia it is found that all the measurements 
of zntermedia fall within the extremes for the series of specimens 
taken on J. bonaparti (as given above). 
Apparently there are no differences in the male genitalia, and so 
we may safely say that specimens of Austrokelloggia from Nothocer- 
cus bonaparti are A. intermedia Carriker. It is unusual that not even 
subspecific differences are found in a species of Mallophaga taken on 
two different host species of tinamous, although it is not by any means 
unique.
