New Mallophaga 
narrow in front, widening rapidly posteriorly, with hind angles rounded, 
and margin slightly convex; with dark lateral bands, thickening at 
the antero-lateral angles. Legs elongate. 
Abdomen of d with sub-parallel sides anteriorly, tapering gradually 
from the fifth segment to the rounded ninth. Pleura of first to sixth 
segments of strong translucent brown, continued forwards and inwards 
into the segment in front, and with a median inwardly directed rounded 
enlargement; of segments seven and eight narrower; all eight segments 
with a broad light-coloured transverse band. Terminal segment rounded, 
with tergum only faintly chitinous. Abdomen of ? broader, widening 
evenly to the fourth segment, whence it tapers gradually to the bifid 
ninth. Pleura as in the S ; but the transverse bands of the first seven 
segments have a broad median interruption. The hind border of the 
eighth segment is the shape of an inverted V; and its transverse band 
seems to be continuous. The ninth segment has the form of two narrow 
triangular lobes, each fringed with a dense pencil of hairs projecting 
from the ventral side. 
The material at my disposal has not been sufficiently well preserved 
to allow of a satisfactory description of the genitaha. In the d, the 
apparatus is complex. The basal plate reaches forward to the anterior 
border of the fifth segment, and its lateral margins become heavily 
chitinised as it passes backwards. The parameres are straight, with 
their tips (Fig. 7) truncated, and bearing a longish hair. But the 
median part of the apparatus is not in fit condition for description. 
Chaetotaxy of $. Forehead with five extremely fine small hairs, 
the fifth just in front of the trabecula; a spine in the eye, and three 
along the lateral temporal margin; a fairly long hair at the angle; two 
spines between this and the pro thorax on the hind margin, and a pair of 
spines inside the occipital border. Prothorax with a pair of short hairs 
on the hind margin. Metathoracic angle with, from without inwards, 
a spine, a hair, a row of three pustulated hairs, followed by a second 
similar row. Abdomen with one or two hairs at the angle, and a pair of 
hairs on the hind border, of each of the first seven segments. Segments 
five to seven have an additional pair of hairs laterally on the hind border. 
Eighth segment with four hairs; ninth terminated on either side by a 
brush of hairs. The S differs only at the posterior end of the abdomen, 
where the square flap of the eighth segment, covering the genital 
opening, carries a row of ten short hairs, and the ninth segment has six 
or seven scattered hairs on each side.
