similar in form to that of the adult and likewise implanted into an oval 
fossa on the ventral surface of the third article. 
The porose areas are absent. 
IV. The Capitulum of the Larva. 
(PI. XIV, Figs. 7 and 8.) 
The capitulum of the larva differs from that of the other stages in 
the relatively small size of its palps and in the fact that it is shorter in 
proportion to its width. The basis capituli is divided on its dorsal 
surface into anterior and posterior portions by a salient ridge, but unlike 
the later stages no ridge is developed on the ventral surface, and in 
addition the posterior portion is not so constricted. As in the nymph, 
a considerable amount of fusion exists between the articles, so much so 
in fact that the only free article is the fourth, the first, second and third 
being solidly fused together. 
The hypostome is smaller than that of the nymph and bears four 
files of about six denticles. 
The chelicerae resemble those of the female and nymph in form, all 
the structures being fully developed as in the adult (PI. XV, Fig. 3). 
The palps are very short and conical, strongly curved laterally 
and deeply concave on their median faces; the lateral angles are not so 
pronounced as in the nymph. They show a considerable amount of 
difference from those of the stages already described ; the tendency to 
fusion of the articles as already shown in the case of the nymph reaches 
a maximum. Article 1 is very small and is exceedingly difficult to 
define; it is completely hidden within the basis capituli: articles 2 and 3 
are the largest, but it is impossible to say with certainty, whether the line 
of folding of the cuticle (shown by a line in PI. XIV, Fig. 7) is the line of 
fusion of the article: article 4 is relatively large and is more terminal in 
position than in the later stages. 
A single feather-like hair is carried on the infra-internal margin of 
the palp, and in addition to this all the others, with the exception of 
the stiff bristle-like hairs on article 4, are serrate on one or both sides, 
as shown in the figures.
