processes (a) attaching basally to a large apodeme or basal plate. Between 
these two processes is a ring-shaped piece (c) which extends forward on to the 
basal plate and terminates distally in a small point. Within this ring-like piece 
are some ill-defined structures that probably represent the true penis.

Previous Records. Known only from the original records, from Cervus 
mexicanus, Central America. 
Specimens Examined. Three males and two females from skin of a deer, 
Mazama sp., Yacuiba, Bolivia, in the collection of the Field Columbian Museum. 
Notes. Speiser (ref. cited) has placed this species as a synonym of 
L. depressa , but if our identification of the species be correct, this is decidedly 
in error, the genitalia of the males being so different that the two certainly 
cannot be the same species. 
In general appearance L. mazamae is very similar to L. depressa, so much 
so, in fact, that the figure given for the female of the latter will apply almost 
equally well for the former. There are slight differences in the arrangement of 
the setae, but no more than might be included within the possible range of 
variation. The presence of a stout apical seta on the inner margin of the anterior 
tibia will permit the separation of mazamae, however. The genitalia of the 
latter (Fig. 2 E) are very different, being not only relatively but actually 
smaller than in depressa and having the inner ring-like piece ( c ) bluntly rounded 
at the tip. 
Lipoptena traguli n. sp. 
Figs. 2 G, 3. 
Specimens Examined. Five individuals, the holotype, a female, and one 
female paratype from Tragidus subrufus Lingga Id., China Sea; the allotype 
and one male paratype from T. russeus Tuangku Id.; and one female paratype 
from T. rubeus Pulo Bintang, Rhio Archipelago. All the specimens are from 
skins in the National Museum and a paratype will be deposited in the collection 
of that institution. 
The hosts are members of the family Tragididae, the “mouse deer.” 
Female (Fig. ._>). Length (on slide) 2*75 mm. General colour, pale brown 
or yellowish. 
Head with narrow, elongate frontal vitta; the ocellar area much reduced; 
the front almost destitute of setae, those which may be present rather small; 
ventral side with but few setae. 
Thorax dorsally with but few setae; pre-alars slender; two pairs of slender 
pre-scutellars and two pairs of scutellars, the outer pair of the latter small.
