DAOTYLOPUS. aL 7 
second joints are exceptionally long and are pectinate 
on the outer margin; the last joint bears at its ex- 
tremity five geniculated setz ; first joimt of the inner 
branch robust, giving origin near the middle of the 
inner margin to a very long plumose seta; second 
and third joints equal, about as long as broad, the 
second bearing two slender terminal setz. In the 
male the first joint is excessively broad (fig. 6), and 
just within its point of attachment is a stout lobe (fig. 
6 a) with a curved spine and two or three small hairs. 
The inner branches of the following pairs of feet are 
considerably shorter than the outer. The fifth pair is 
of moderate size, the basal joint short and broad (fig. 
8), its internal segment not much produced, fringed 
with afew short hairs and five setze of moderate length ; 
the second or outer joint is small, about as long as 
broad, and is also provided with five setz. In the 
male the basal joint is less developed (fig. 9) and has 
only two sete, but the second joint is larger, more 
angular, and bears five strong spine-like setz on the 
outer, and one of more slender build on the inner 
margin. ‘The tail segments in the female (fig. 10) are 
rather longer than broad, bearing three sete, the inner- 
most of which is the longest, but scarcely equals the 
length of the abdomen; in the male (fig. 11) the last 
abdominal ring is also partially divided, forming a 
portion of the caudal fork; the tail setze are consider- 
ably dilated towards the base, and the inner angle of 
the caudal segment gives attachment to a narrow 
lancet-shaped spine (fig. lla). Colour yellowish 
brown. Length 5nd of an inch (‘6 mm.).
