A NEW SPECIES OF PAUROPUS FROM VICTORIA 153 
it is about half the length of its flagellum. The lower ramus of the antenna measures 
about five-eighths of the length of the upper ramus, and is about three times as long 
as broad ; its anterior flagellum is only very slightly shorter than the posterior, and 
measures about 24 times the length of the lower ramus. The globulus (fig. 2B) 
is comparatively small, and is about twice the width of its very short stalk. 
Trunk. This is of medium build, being neither exceptionally slender, nor, com- 
pared with other species, markedly robust. It gradually widens up to the fifth 
segment, and beyond the seventh tapers more sharply. 
The dorsal shields are approximately rounded, the first being about the breadth 
of the head. They are completely devoid of pubescence. The setae are cylindrical 
with blunt ends; and though some are slightly swollen at the tips, they are never 
markedly clavate. The six setae on the penultimate segment are all rather enlarged, 
and measure about one-third the breadth of the segment (fig. 3A).

The fifth pair of tactile setae (trichobothria) measures about 0-3 mm. in length, 
and is about twice as long as the breadth of the segment (fig. 3A) ; along its distal 
two-thirds is a very delicate close pubescence, but the proximal third is naked. 
The fourth tactile seta is a little less than four-fifths the length of the fifth; like 
the fifth it is faintly pubescent, the basal end alone being bare. The third seta is 
rather more than half the length of the fifth, and about three-quarters the breadth 
of its segment; it is faintly pubescent to within one-quarter its length from its 
base. The second and first setae are about half the length of the fifth, only the 
distal half being faintly pubescent. 
Anal segment (fig. 3). At its posterior tip the tergum of the anal segment grows 
out as an inconspicuous thin protuberance above the “anal plate,” but is not as
