curvicornis. It is simply an unusual coincidence that males of 

 curvicornis without females of the same species, and females 

 of another species (our new one) have been taken without the 

 males, but the pheasants are so heavily parasitized, Argji- 

 sianus argus already having four Mallophagan species recorded 

 from it, that the coincidence is not at all an impossible one. 

 Fortunately we have found several females of G. curvicornis, 

 together with males, in the present lot. They were taken from 

 Argusianus argus, and, as described in this paper under the 

 proper species caption, are unmistakably Hke the males in species 

 characteristics. 



The new species is characterized by its short straight abdo- 

 men, which instead of being elliptical or sub-spherical in the 

 male as is usual in Goniodes, is parallel-sided in both sexes. 

 The abdomen of the male is not as long as the head and thorax 

 togetlier. The head of the piale has shallow, concave tem- 

 poral margins, and the antennae are very large and bear forked 

 processes on the first segment, and the appendage of the third 

 segment is strongly chitinized, very long and pointed so as to 

 be almost claw-like ; the last two segments appear as appen- 

 dages to the third. The genitalia of the male are large, and 

 in both specimens that \^■e have are exserted. This exsertion 

 is probably unnatural but may, because of the small size of 

 the abdomen and unusual size of the genitalia, be natural. 

 The general colour of both sexes is pale yellow with but few 

 darker red-brown markings. 



Description of male : Head sub-quadrilateral with rounded 

 front, sides not expanding, the width across the temples 

 but little exceeding that across the base of the clypeus. Front 

 rather prominent and evenly rounded with a light brownish 

 marginal band, terminating in two antennal blotches ; a rather 

 long hair and four short ones on the clypeus on each side 

 The antennae (plate xv, fig. 6a) are set in rather deep emar- 

 ginations ; the first joint is very large, as long as all the succeed- 

 ing together, and bears midway on its posterior margin a most 

 prominent forked appendage bearing a stout spine between the 

 two forks ; the second segment is half as long as the first and 

 bears a smaller appendage on its inner margin ; the third seg- 

 ment is practically all appendage, is long, curved and claw-like 

 and bears the last two segments of the antenna near its base, 

 having the appearance of an appendage of the third ; of these 

 last two the first is very short and the last about half as 

 long as the second ; a few short hairs are present. The eye is 

 prominent with an inconspicuous fleck and a short spine. Behind 

 the eye the sides of the head are slightly concave and bear 

 a short spine; on the rounded temples are two long, stout 

 hairs, a short spine behind them and a prickle between, and 

 farther back on the blunt posterior angle is a stout spine. 

 The occiput is concave and the occipital l)and prominent, form- 

 ing two pnle blotches.
